Warm greeting to industry friends and colleagues!

India formally joined the Paris climate change agreement on Gandhi Jayanti, taking the global pact a step closer to its enactment. As India reaffi rms its global leadership on tackling climate change, I would like to congratulate the eff orts made by our Industry friends and colleagues in making Perform Achieve and Trade (PAT) scheme a success, which has made a huge contribution in propelling India on a low carbon growth trajectory. While the PAT scheme sets a powerful example on how individual industry level eff orts and commitment to energy conservation and effi ciency can contribute to making India energy secure, the targets achieved by the industry have set international benchmark on achieving energy effi ciency in many sectors. The industry has already set to overachieve fi rst PAT cycle specifi c energy consumption targets by 30% and I am happy to note that through the ‘Knowledge Exchange Platform (KEP)’ we were able to support the industry in realizing these targets by building a knowledge economy and inspiring industries to focus on strategies and solutions that can enhance their energy productivity. This role of KEP will become particularly important for new industries and sectors that have been covered under the second PAT cycle, where the challenge will be to replicate the success achieved so far and to create a smart economy reinforced by green manufacturing and production.

As Industry braces itself to achieve the targets under the second cycle of PAT, there will be a need to bring in knowledge and enhance access to new and innovative technologies and services that help them to improve their energy performance on a continuous basis. To realise this potential, KEP has initiated sector wise technology gap assessment and mapping of best available international technologies to bridge the information gap. To compliment this process, we have also created a searchable database on energy effi ciency technologies, service providers and technology supplier’s among host of other resources that can help industry choose from a range of options and guide the users on best technologies suited for their industry. Recently, we brought the industry, technology suppliers and other important stakeholders on a common platform to exchange knowledge on technology options and approaches through a National Seminar cum Technology Exhibition organized on 7th to 8th November, 2016 and I would like to thank my industry partners for their wholehearted participation in this event.

Potential benefi ts of Co-processing RDF

Co-processing of MSW in cement plants has the potential to eff ectively address many waste disposal challenges facing the country.

• Addressing local environment issues by reduction of MSW going for landfi lls.

• Addressing health and social issues by breaking cycle of diseases resulting from unhygienic conditions.

• Creating sustainable livelihood option for the informal sector involved in waste picking, sorting and recycling by making these operations organized.

• GHG reduction potential by replacing coal in cement kilns. Additional GHG reduction through methane avoidance from landfi ll.

• Huge Coal saving potential by using waste in place of coal for cement manufacture

For circulation within the KEP network only

Effective management and disposal of Municipal Solid Wastes (MSW) has already reached a stage of major concern in India, as in many other countries around the world. Rapid urbanisation, uncontrolled population growth and rising per capita income is only going to add to this problem. The significance of the issue can be understood from the high priority accorded by the Prime Minister of India, Narendra Modi under the Swachh Bharat Abhiyaan (Clean India Campaign). This campaign is India’s biggest ever cleanliness drive where eminent people from different walks of life are being encouraged to promote it. But the challenge is huge. The total estimated generation of MSW in India is about 68 million tonnes (2011-12) from urban sources alone. MSW generation from major Indian states is illustrated in Figure 1. The generation of MSW is estimated to reach 221MT in 2030, with a per capita increase of 1 to 1.33% annually.

Landfi ll/ Waste dumps or open burning (60%- 90%) continue to be the principal method of waste disposal causing severe health hazard, continuous emission of harmful gases and environmental degradation. Despite adverse impacts, land fi lling is expected to continue as most widely adopted practice in coming years, even though the major cities are already facing problem of land availability

for waste disposal. Local Municipal Authorities responsible for handling wastes face severe challenges, signifi cant among them being scarcity of funds, inherent institutional weaknesses, lack of capacity and knowledge on choice of method/ technology for waste disposal.

MSW Co-processing in Cement Plants: an eff ective solutionIn a situationas grim as this, it becomes imperative to look at customized non-conventional solutions involving all stakeholders responsible for solid waste management. Making Refuse Derived Fuel (RDF) from MSW and using it gainfully as a fuel in cement plants is one such sustainable long-term solution. RDF is the dry organic fraction of MSW which can be recovered by treating MSW using Mechanical Biological treatment. RDF comprises of plastics, paper, cardboard, cloth, wood, rubber, leather, etc. This option represents a win-win situation by way of reducing coal usage in cement manufacture on one hand and in finding a long-term sustainable solution for managing urban waste effectively on the other. As illustrated in Figure 1, states like Maharashtra, Gujarat, Rajasthan, Andhra Pradesh, Karnataka & Tamil Nadu, which produces large quantities of MSW also have number of cement plants which can absorb the RDF in these states.

However, despite many potential benefits, RDF usage is not getting scaled upin India. Typically, RDF can replace up to 15-20% of primary fossil fuels used in cement plants. However, the current thermal substitution rate (TSR) or the rate of co-processing wastes in India ranges between 0.5-1%, while in some developed countries, this figure is as high as around 60%. There are some cement plants in Europe where more

than 80% of the conventional fuel is being replaced with RDF.

Models of MSW co-processingInstitute for Industrial Productivity(IIP) commissioned a project to analyse the issues and challenges facing RDF projects in India. Three different models processing MSW to RDF for usage in cement plants, were studied. These models were carefully selected to cover projects that are being managed by different types of stakeholders viz. (i) Municipal Corporation (Panjim Model); (ii) an NGO (Sarthak Model); (iii) Cement manufacturer (Jaypee Model), to get a range of perspective, understand their implementation challenges and review their comparative advantages/

disadvantages. Each of these models involve different actors in its operations, handle different nature of waste and have varying degrees of mechanization in production process.

Panjim Model

The city of Panjimin Goa generates around 60 tonnes of waste every day, and this fi gure is rising at a rate of 5% every year. To handle this waste eff ectively, primary segregation is done at the household level by providing separate bins for collecting and storing bio-degradable and non-biodegradable wastes. The organic bio-degradable waste is composted in pits to produce manure. The non-biodegradable wastethat constitutes about 12% of the total waste, is further segregated into recyclable and non-recyclable waste, by Municipal Corporation employees. About 0.8 tonne per day of non-recyclable wastes can be processed as RDF, however, the facility generates an average of 0.36-0.40 tonnes of RDF per day.Bales of RDF weighing about 100-110 kg are transported from processing facility to cement companies for use as fuel.

Although the project has greatly enhanced the effectiveness of the waste management system in the city, the model is not sustainable. While the total cost incurred by Municipality is INR 1100 (USD 18)per tonne, it derives no revenues from this activity as the RDF is supplied to the cement companies free of cost. The revenues obtained through “sanitation fees” levied by the Municipality is able to cover only 12-15% of the total cost of this project.

Sarthak Model

The city of Bhopal in Madhya Pradesh generates around 420-460 tonnes of MSW every day. About 5,000 rag pickers were involved in this city to segregate the waste in an unhygienic manner that was also hazardous to their health. The plastic waste constituting around 14% of the garbage, was dumped either at a centre near Bhopal-the state capital or burnt. Both these practices were

highly harmful for the environment and overall health of the inhabitants in the city. So, in order to improve the waste management system and the working conditions of rag-pickers a local NGO, Sarthak, initiated a project on MSW processing, which was supported by Bhopal Municipal Corporation (BMC). BMC allocated land to Sarthak for solid waste management and collection of plastic waste. This initiative was started in five of the 70 management wards of BMC, and is now being implemented in 21 wards, employing 1465 “SarthakKarmis” (rag-pickers). The NGO has carried out capacity building of Sarthak Karmison waste management processes and has also linked them with social security schemes. The Sarthak Karmiscarry out the collection and segregating of wastes, which is transported to the processing facility, where the waste is aggregated into bundles of 100 kg. This process generates 5-6 tonnes of RDF every day. RDF is sold to cement plants at a rate of INR 5.50 (USD 0.09)per Kg,for use as fuel. Till now, nearly 2000 metric tons of plastic bags have been used as fuel in cement plants, saving nearly 5,000 tonnes of GHG emission from burning of plastic waste. Furthermore, rag-pickers have been employed, in a job that pays them an income higher than what they were earning earlier. Discussions with local cement companies reveal that they are generally happy with this, but in order to be sustainable, cost effective and scalable this model needs to promote primary segregation of wastes at the household level.

Jaypee Model

Chandigarh city generates about 400 tonnes of solid waste every day and to deal with the issue of its safe disposal, Jaypee Cement Industries has setup a highly mechanized system, for the waste collection and processing in Chandigarh that caters to 70 % of the waste generated in the city. The segregated waste comprises of a mixture of plastic and textile wastes, which is processed and converted into RDF without any primary

Figure 2: Typical waste management process

segregation. While this model is based on an efficient technology, however, it is not financially viable for Jaypee. It incurs INR 2500 (USD 41)per tonne on processing of wastes and recovers only INR 1750 (USD 28.7)per tonne by way of selling the product. Inadequate supply of waste is another significant obstacle faced by Jaypee in this project.

Comparison between the three Waste Management ModelsA typical waste management process is depicted in Figure 2, where the major stages are demarcated as A, B, C & D. For an effi cient waste management model, primary segregation (A) is an important

NEWSLETTER ISSUE-6, SPECIAL EDITION-ENMS 20164

step. The management arrangement and responsibility for each stage of waste management in different models is presented in Table 1.

One of the major issues identified for impeding the rapid scale up in all the three model is the poor financial viability of these projects.The salient feature of these models on key financial parameter is depicted in Table 2.

Way forwardThe Indian cement industry has made significant improvements in its energy efficiency and productivity in the recent years. However, the Thermal Substitution Rate (TSR) or the use of Alternate Fuels and Raw Materials (AFRs) for cement manufacture, remains extremely low. India which is the second largest producer of cement in the world after China, is likely to see its cement capacity of 350 Million Tonnes per annum (Mta) double over the next decade, resulting in a huge surge in coal demand. This demand for coal is projected to increase in the range of 63 –to 96 Million Tonnes (MT) during 2012 – 2017 as per the Planning Commission’s 12th Plan Report on cement industry. The role of AFRs to replace coal therefore assumes great significance against this backdrop.

Increasing TSR in cement industry offers not only huge opportunity for reducing fossil fuel usage but also in addressing the issue of local as well as global emissions. The time is right to launch a structured campaign for AFR, keeping in mind the following recent developments.

i. Government of India has pledged to higher targets for emission intensity reduction in the Nationally Determined Contribution (NDC), which would translate in to greater push for manufacturing sectors like cement to reduce their emission intensity

ii. More challenging targets to cement industry under second cycle of Perform Achieve and Trade (PAT) scheme implies that the industry will have to look at opportunities like AFR to achieve these targets.

The GHG mitigation cost through AFR use is reasonable, and there is a significant replication potential across the entire cement industry in India. The other associated co-benefits include an effective and efficient means of managing urban and industrial waste, which is increasingly becoming a cause for major concern. The relatively low use of AFR is diagnosed to be due to a number of technical and financial issues coupled

with policy and regulatory barriers, many of which are interlinked.

IIP India has launched a multi-stakeholder initiative to draw up a stakeholder-designed ‘Implementable Action Plan’ (can be downloaded from www.iipinetwork.org) for increasing the TSR in Indian cement industry. In order to identify and resolve the regulatory and policy issues, IIP had created a Forum of Regulators with high level representation from State Pollution Control Boards of major cement producing states in India. The Forum of Regulators (FoR) reviewed the provisions of existing policy and regulatory guidelines and came out with a series of five White Paper Compendium (can be downloaded from www.iipinetwork.org), based on which the Central Pollution Control Board (CPCB) has now set up a ‘National Task Force (NTF) on Co-processing’, to take the recommendations of the Forum forward, which provides the much needed framework to deal with some of the pressing regulatory and policy barriers. While NTF reviews the policy and regulatory provision to enhance the use of AFR, it is important to draw policy learnings from other countries, which have been successful in enhancing the TSR rate. The UK Landfill Tax is seen as one such key mechanism for increasing TSR in cement industry by making it financially more viable compared to the cost of landfill.

Consultations with Cement industry show that they are willing to invest in technologies that can help them increase the TSR (while helping them meet their PAT targets). In a recently (Sept., 2016) conducted UK study tour under Knowledge Exchange Platform (KEP) initiative, the Indian cement industry representatives were exposed to such technologies for waste co-processing, their economics and benefits. KEP will continue to provide information on similar technological options available for enhancing TSR. The cement industry will however need to capitalize on these opportunities for not just achieving scale of energy efficiency, GHG mitigation and coal savings,but in also contributing to the society by gainfully utilising MSW/Solid waste.

– Mr. Bijneswar Mohanty(AVP, Head Cast house & Energy Management) , Mr. Ramesh Chandra Patro(Associate Manager, Coordinator Energy Cell)

Introducing the Plant

Vedanta Ltd. (VL), Jharsuguda, is an associate company of the FTSE 100 diversifi ed resources group Vedanta Resources Plc, listed on the London Stock Exchange. Originally incorporated in 2001, Vedanta is a leading producer of metallurgical grade alumina and other aluminium products, catering to a wide spectrum of industries. The aluminium smelting unit at Jharsuguda has carved out a niche for itself in the aluminium industry with its superior product quality based on energy effi cient state-of-the-art technology. The fi rm operates a 0.5 MTPA aluminium smelter and a 1215 MW captive power plant supported by highly modern infrastructure at this location in Odisha.

In the quest to meet high quality standards and the best of Health, Safety and Environment systems, the company hasput into place an integrated management system (IMS) and is certifi ed for: ISO 9001, ISO 14001, and OHSAS 18001 and ISO 50001.

Development strategies adopted for implementing ISO 50001, Energy Management System

Development Strategies:

At Vedanta, we believe that teams are always better than individuals and systematic tools are more fruitful than solitary ideas. Cross-functional team involvement in Focused Improvement Projects to improve energy performance by optimizing processes, innovating, implementing new ideas, and also using the latest technology, have all helped

achieve signifi cant reductions in energy consumed.

The top management’s role in implementing and maintaining such a system is vital and incudes,

Formation of an Energy Cell (Fig 1.) comprising a three-layer structure: an apex committee, core committee, coordinating committee and Small Group Activities (SGA) team. (refer to attached Annexures 1 and 2, for details of the Energy Cell and Energy Management Team’s roles and responsibilities).

Defi ning an energy policy taking into account all organizational and legal requirements.

Appointing a management representative (MR) and Energy Manager to drive the system.

Defi ning the roles and responsibilities of the MR and Energy Manager.

Establishing energy objectives and targets according to energy policy and providing necessary resources for achieving them. (necessary resources include approvals for CAPEX (capital expenditure) and OPEX (operational expenditure) proposals aimed at implementing energy saving projects, computerization of all energy reports, energy-effi cient procurement, design, etc., and training human resources).

Training all plant personnel in energy conservation awareness.

Reviewing the energy

performance of the plant periodically.

Our team is actively involved in spreading awareness about energy conservation in the community and in industry: we also conduct workshops at national level. Vedanta organized the fi rst aluminum sector KEP (Knowledge Exchange Platform) workshop involving all players in the aluminium industry, research institutes, and the Bureau of Energy Effi ciency, Government of India.

Energy review and planning

The energy review is the heart of this management system. All aspects of the EnMS depend on it so proper energy plans and reviews are a must for successful implementation of EnMS. An energy review exercise is conducted every year. The energy planning process includes:

a. Identifi cation of diff erent energy streams used in our plant.

b. Analysis of energy use and consumption.

c. Determination of areas of signifi cant

Figure 1: Formation of Energy Cell

NEWSLETTER ISSUE-6, SPECIAL EDITION-ENMS 20166

energy use and consumption (by Pareto method).

d. Analysis of past and present energy consumption, so as to determine the baseline for each area.

e. Analysis of relevant variables impacting significant energy use.

f. Identifying opportunities for improvement.

g. Setting out objectives and targets.

The energy review exercise involved the Energy Cell team: the energy consumption of motors, lights, different parts of the process, furnaces, etc.,were measured using a power analyzer and recorded for analysis. This procedure was followed for all types of energy streams.

To monitor energy performance, energy performance indicators (EnPI) were defined for each area, and,based on past and present energy consumption, baselines were set for each EnPItaking the average energy consumption over a year.

A list of opportunities was drawn up using audits, brainstorming sessions, sharing best practices, etc., and then priorities set, based on conditions such as payback, feasibility, process impact.

Use of Professional Expertise

During the implementation stage an energy consultant guided our team in developing energy review formats, trained the internal auditor, provided information about best practices in other industries, all of which helped us develop a robust system not only for complying with all the requirements of an EnMS but also for achieving national benchmarking figures of energy consumption.

Human resources are the key to success in any organization, hence it is of utmost importance to train them and develop skills. To enable focusing on this, our policy mandates every department to conduct training sessions on energy conservation. The HR department conducts training programmes and monitors their effectiveness.

1. Training by external agencies

Agencies from outside the organization were called in to train the Energy Cell team in techniques of energy auditing, energy management and energy saving in different kinds of equipment.

Training on the following topics was carried out by external agencies mentioned alongside:

Energy auditing techniques: CII

Energy saving in utilities: FICCI

Energy management training: CII

Internal auditor training: GRK enterprises

Lead auditor training program: SGS

We are also encouraging our engineers to go through the BEE-certified Energy Auditor’s course and we now have eight government-certified energy auditors and managers.

2. Training by faculty within the organization

As per the internal training calendar, in-house specialists provide refresher training for internal auditors, and EnMS, as also in areas such as:

Energy savings in pump and motors

Energy efficiency in pot cells.

Energy efficient lighting, etc.

3. Tool Box talks cover energy conservation awareness for shop floor personnel

Tool box talks are organized each fortnight for shop floor technicians and operators, on energy savings, deviation reporting and control, to communicate of the energy policy, objectives and targets, etc.

Online e-testsare being organized to evaluate the competence of all employees who are significantly impacting energy. We also invite vendors to participate in workshops and demonstrate energy efficient products and educate our Energy Cell team members by exposing them to national international symposiums.

Tools and resources

The Jharsuguda plant of Vedanta has a value-driven culture with strong business drivers such as Six Sigma, Quality Circles,

NEWSLETTER ISSUE-6, SPECIAL EDITION-ENMS 2016 7

before and after the training. To increase awareness, posters and dashboards are displayed on the shop floor.

Approach to determine energy performance improvement and validate results

Before implementing the energy saving projects, the SGA team of our Energy Cell measured energy consumption and other process parameters such as pressure, flow, temperature, and recorded them in a specified format. All these parameters, including energy, current, voltage, etc., were again measured (after implementation) to enable a comparison. The results were verified by an internal auditor/central EnMS coordinator.

Details of the modifications along with photographs and other data are recorded in a specified format for reference and the final result verified by the Energy Manager.

Cost-benefit analysis

Cost-benefit is calculated on the basis of costs of the project, maintenance, operations, and finally comparing this with savings due to reduced energy consumption.

Annual energy cost savings

1634.66 lakhs INR

Cost to implement 224 lakhs INR

Payback period 2 months

The work force is skilled, well- trained and competent. An in-house laboratory carries out quality tests on in-coming material, in-process material and the fi nal product.

Development strategies adopted for implementing ISO 50001, Energy Management System

Development phase:

• In order to have a well-defi ned and functional energy management system, the members of the organization should become conscious of energy consumption, conservation and wastage.

• With a well-organized system for collecting and measuring data in place, consumption fi gures for diff erent departments were readily available, allowing a systematic approach to understanding energy use. With this data we were able to study our past consumption and fi nally, a baseline was arrived at: the fi nancial year, 2014-2015.

Analysis of the data suggested that electricity was the form in which most energy was consumed. Hence, monthly electricity consumption for all departments was recorded separately and the annual total was determined. This allowed determination of areas of signifi cant energy use (SEU): if the area consumed more than 5% of the

total electrical energy consumed it was considered an area of signifi cant energy use. For each department, Energy Performance Indicators (EnPIs) were based upon the energy consumed per unit of production.

Use of Professional Experience:

The plant identifi ed the level of training for diff erent personnel according to their job profi le. The top management’s commitment to EnMS implementation was high and hence a management representative (MR) was appointed with immediate eff ect. The MR was given powers to make decisions with respect to the EnMS and he was also responsible for assigning roles and responsibilities to other members of the organization. The major resource was a team which comprised 15 experienced and dedicated members from all over the plant, specialists in their respective roles: this team was hence called the Energy Management Team (EMT) with the MR as their leader.

The MR and EMT played key roles in implementing the EnMS and hence specialized training by certifi ed external experts from the Bureau of Energy Effi ciency (BEE) on EnMS implementation and internal auditor training was arranged.

These members were, in turn, responsible for training the other staff members in their departments. In particular, a number of training sessions were arranged for ground level workers working in the SEU area, because they were the fi rst in line to work on the machines and had a signifi cant role to play in energy conservation and preservation.

A clear communication system was set up with details and updates on EnMS were

circulated to all concerned personnel via e-mail; all the latest documents, records and data were placed on the intranet so as to be accessible to all staff members. Notice boards were also used to intimate workers of progress; control was maintained throughout by using passwords to protect all relevant documents on the intranet.

Workers were trained on the process fl ows of the machines. They were also given proper instructions about how to operate the machine effi ciently. For this purpose the instructions were noted down on a paper and placed near the machine to ensure good operational control.

Implementation roadmap of ISO 50001 and approach adopted

A number of activities were undertaken to improve the energy performance of the plant, and included replacement of old ineffi cient motors by IE2 class high-effi ciency motors, as also VFD and LED light installation, all of which resulted in signifi cant improvements in energy consumption. The energy effi ciency improvement projects were fi rst documented and a detailed action plan consisting of responsibilities and time frames was drawn up, with steps taken to implement it. Performance was measured using regression since it considered all variables aff ecting energy use.

The energy team prepared a template for determining energy consumption and validation in Excel format. This template used the baseline data, regression, and some mathematical calculations to compute the energy consumption for the current period. A report was generated showing the diff erence between the actual and computed values of energy consumed with values deviating from preset limits, being colour-coded. Reasons for these deviations were given by the department’s energy team member.

Since the system was fully integrated and scattered bits brought together, preparing for audits was no trouble. Only minor things such as placing the instructions at proper places near the machines, checking

the availability of documents, needed to be checked.

ISO 50001 and the PAT scheme

After implementing ISO 50001, the plant was able to reduce its energy consumption by 9.81% during the 1st PAT cycle.

Cost-benefi t analysis

Replacing conventional lights by LEDs and installing VFDs in place of conventional starters saved Rs. 2.55 million, with a total investment of Rs. 2.44 million. Other contributions to savings came from the installation of solar light pipes, interlocking for ETP aerator motor, and replacement of obsolete motors by high-effi ciency motors. It was the hard work of our team that led to a timely completion of the projects aimed at saving energy, giving a payback period of one year.

Challenges • As a composite textile mill, the largest

hurdle that came our way was a gap in competence and training. Since the number of processes is large, the training and competence of workers working in each process was diff erent and the gap had to be made up. After a long brain-storming session with the Human Resources personnel, it was decided to make a department-wise competency matrix which would also cover the training needs in a single context.

• Because of the presence of diff erent kinds of machinery with diff ering loads, varying from 0.375 kW to 135 kW, the number of motors was correspondingly very large, approximately 3000. This made it diffi cult to identify and set the criteria for SEU equipment; however, after studying all the aspects and possibilities a value of 100 kW for connected load of individual or group

of machines was considered to be taken as the base value for further analysis.

It was indeed a big task to implement the energy management system, but the willingness and dedication of the organization brought success. Many lessons were learned as the projects were implemented: team work, sharing of responsibilities, accountability, and time management played a key role in implementing EnMS.

Keys to Success• A suitable system / method for timely

data collection and measurements of energy consumption within the plant’s boundary.

• Awareness amongst the people working in the plant is essential because no system/process/method can be brought into practice without knowing its signifi cance.

• Good computer operating skills, especially for working with MS Excel, came in handy in EnPI measurement and analysis.

Introducing the Plant

Shree Cement Limited (SCL) is a leading Indian cement company and its approach in transforming risks into opportunities has given it a notable presence in the national cement industry. It is India’s third largest cement company with a cement production capacity of 25.6 million tonnes per annum. SCL commenced operations in 1986 with a production capacity of just 0.6 million tonnes per annum. With changing times and needs, SCL diversified its business portfolio and entered the power sector with a commercial power plant, Shree Mega Power,whose generating capacity was 300 MW. If 201 MW of captive power is included, the total power generation capacity becomes 501 MW. The capacity of this plant is augmented by 111 MW from the waste heat recovery plants (WHR),making a total of 612 MW. The capacity of SCL’sWHR power plant is, worldwide, second only to similar plants in China. WHR-based power plants are located in Beawar, Rasand Raipur.

Development strategies adopted for implementing ISO 50001, Energy Management System

Identification of Energy Aspects and Prioritization

• All members of the core team, comprising personnel from concerned departments such as Process, Mechanical, Electrical, the power plant,together with a Management Representative,conduct an energy review (aspect identification and evaluation) initially. While identifying and evaluating energy aspects, the

following are considered.

• Analysis of energy use and consumption based on measurements and identification of current energy sources. Past and present energy use and consumption are also evaluated.

• Based on the analysis of energy use and consumption, areas of significant energy use are identified as are also facilities, equipment, systems, processes and personnel working for, or on behalf of, the organization that significantly affect energy use and consumption. Other relevant variables affecting significant energy uses are identified. Current energy performance of facilities, equipment, systems and processes related to significant energy uses are identified and future energy use estimated.

Determining Criteria for Potential Savings and Feasibility

Once the energy aspects are identified, their significance is reviewed; the two significance criteria include, “Potential Savings” and “Feasibility”. Both these, Savings Potential and Feasibility, are added to determine which energy aspects are significant: aspects totaling to more than 10 are considered significant. The table below illustrates how the significant criteria are determined.

The significant aspects are further examined to determine energy factors, opportunities for savings and required investment. Details are recorded in the register of opportunities (ROP).The above criteria are used to prioritize among the opportunities available based on payback period and use of renewable energy. An action plan for tackling the significant aspects based on priority is drawn up and recorded in the register of opportunities (ROP). The action plan could be in terms of an EnMP or check sheet or work instructions, or a combination of all these. The delegation of responsibilities for the action plan is also mentioned in the ROP. All members of the core team, comprising personnel from the concerned departments shall establish an energy baseline using the information in the initial energy review, considering a data period suitable to the organization’s energy use and consumption. Changes in energy performance shall be measured against the energy baseline. Adjustments to the baseline shall be made in the case of one or more of the following:

1. The Energy Performance Indicators (EnPI) no longer reflect organizational energy use and consumption,

2. There have been major changes to the process, operational patterns, or energy systems, or,

3. According to a predetermined method.

Use of Professional Expertise

The plant regularly provides three kinds of training to their personnel: organizational needs, functional needs and individual needs. In FY 2014-15, 1,153 internal and external training programs were conducted across all SCL units, totaling

77,179.56 training man hours –a key highlight of our People Development Agenda. We are attempting to customize the training programs based on the individual learning style of employees in the coming year. In addition to classroom training, we also incorporate innovative and interactive modes of training such as role plays, theatre, workshops, movies and case studies to ensure that the sessions have a higher recall value.

Cross-functional training is an important aspect of our training sessions wherein employees are encouraged to work across departments, learn new skills and aspire for all-round development. This is aimed at building a team of people that comprehends the views of other teams and is able to address cross-sectorial challenges.

Energy Management System Implementation

Raymond Limited, Jalgaon Unit

– Mr. Sanjay Bokare(Dy.GM Engg.), Raymond Limited, Jalgaon Unit

Introducing the Plant

The Jalgaon Division of Raymond Ltd. was established in 1979 with a manufacturing capacity of 79 lakh meters per annum, of worsted suiting. The worsted division manufactures worsted suiting fabric with polyester-wool and polyester-viscose blends.

Strategies adopted for implementing ISO 50001, Energy Management System

Development phase

• The top management is committed to establishing the EnMS system because of its direct eff ect on operation costs. This is encouraged by providing separate funds, and involving the heads of each department, who decide issues related to EnMS implementation and use available resources.

• An energy team was formed comprising young and energetic members together with experienced members. Each team member’s responsibility was clearly defi ned, as were timelines.

• The team identifi ed current energy sources, evaluated past and present energy use and consumption. Based on this, analysis areas of signifi cant energy use were identifi ed. Also identifi ed were the facilities, equipment, systems, processes and personnel working for, or on behalf of, the organization that signifi cantly aff ect energy use and consumption. Other relevant variables aff ecting energy use signifi cantly were also identifi ed.

• Estimates of future energy use and consumption were also drawn up; opportunities for improving energy performance were identifi ed, priorities listed and recorded. Based upon the energy review, an energy baseline for each SEU was set as was also a target for each department.

Use of Professional Experience:

A professional was hired to guide personnel and implement EnMS 50001. He provided training customized to the level of the employee and made them aware of the EnMS system and how to implement

it. An Idea Box has been set up in every department to collect suggestions from shop fl oor workers, with the best suggestion of the month being awarded, so as to encourage the workmen. At middle level, there is a monthly meeting to assess whether the EnMS system has been implemented eff ectively.

Tools and resources

The plant was guided by a BEE-certifi ed energy auditor. Help was sought from external experts to implement ISO 50002:2014, ISO 50003:2014, and ISO 50004:2014. ISO 14001:2008 was a very handy tool in the implementation of the EnMS system.

Steps taken to maintain operational control and sustain energy performance improvement

The plant listed some Critical Operating Parameters (COPs) for each department and monitor these parameters continuously; the COPs are prominently displayed in each department. Specifi c consumption in the plant was monitored each day.

Approach used to: 1) determine whether energy performance improved, and, 2) to validate results

1. Monitoring of specifi c energy consumption of each department.

2. Monitoring of plant’s monthly power consumption.

3. Monitoring of effi ciency and machine utilization.

4. Measurement of power consumption using energy meters installed in each area.

BEE’s Financing Initiatives

– Ms. Vineeta Kanwal, Assistant Energy Economist, Bureau of Energy Efficiency

India’s objective of attaining sustainable economic growth is directly related to the efficient management of its energy resources. The Government of India is implementing a large number of programmes addressing the country’s economic challenges: closely linked to these is bridging the gap between the demand and supply of energy: energy efficiency has a vital role in this role to bridge the gap between the demand and supply of energy. In June 2008, the Government of India released the National Action Plan on Climate Change (NAPCC) with the objective of achieving a sustainable path of development advancing both, economic and environmental objectives. The National Mission for Enhanced Energy Efficiency (NMEEE) is a key component of the NAPCC, under which the Ministry of Power and BEE have launched the Framework for Energy Efficient Economic Development (FEEED), and Energy Efficiency Financing Platform (EEFP).

The BEE has constituted two funds under the FEEED, the Partial Risk Guarantee Fund for Energy Efficiency (PRGFEE)and Venture Capital Fund for Energy Efficiency (VCFEE) to bridge the gap between demand and supply of capital investment in energy efficiency projects.

The PRGFEE is a risk-sharing mechanism to provide financial institutions (banks and NBFCs) with a partial coverage of risk in extending loans for energy efficiency projects. The guarantee will not exceed Rs. 10 crore per project or 50% of the loan amount, whichever is less. The Government of India has approved Rs. 312 crore for the PRGFEE covering the following sectors: government buildings, private buildings with commercial or multi-storey residential accommodation,

municipalities, SMEs and industry. The Ministry of Power has a constituted a supervisory committee to monitor the implementation of the PRGFEE. The BEE appointed an Implementing Agency (IA),a consortium comprising RECPDCL-REC-EESL,toope rationalize the PRGFEE, in July 2015. Many public and private sector banks have shown an interest in this programme with Yes Bank signing a charter with BEE in 2015 to this effect. IDFC Bank, Tata Clean tech Capital Ltd., and Andhra Bank have, so far, been empanelled by BEE.

BEE and Implementing Agency have prepared the Operations Manual for the PRGFEE and created a pipeline of few projects to be covered under this guarantee mechanism. PRGFEE rules were notified by the Ministry of Power (MoP)in May 2016.

The Venture Capital Fund for Energy Efficiency (VCFEE) is a fund to provide equity capital for energy efficiency projects. A single investment by the fund is not to exceed Rs. 2 crore. The Fund provides last mile equity support to specific energy efficiency projects, limited to a maximum of 15% of the total equity required, through Special Purpose Vehicles, or Rs. 2 crore, whichever is less. Sectors covered under VCFEE are government buildings, private buildings and municipalities. The Government of India has approved Rs. 210 crore for this Fund. The MoP has constituted a Board of Trustees for VCFEE and the trust was registered on 7th July 2015. The BEE has already identified SIDBI as the Fund Manager for VCFEE; the notification of VCFEE rules bythe MoPis underway.

In a recent market survey of ESCOs being carried out by USAID-PACE-D team for energy efficiency projects in 2014-16,it

has been estimated that there is a debt requirement of Rs. 450 crore and an equity requirement of Rs.185 crore for energy efficiency projects.

The Energy Efficiency Financing Platform (EEFP) is an important initiative under NMEEE whose objective is to provide a platform for interaction with financial institutions and project developers to implement energy efficiency projects. As part of this programme, MoUs have been signed with financial institutions to work together for developing energy efficiency market side ntifying issues related to this market development. The BEE is signing MoUs with M/s. PTC India Ltd, M/s. SIDBI, Tata Capital, and IFCI Ltd to promote financing for energy efficiency projects.

In 2015, BEE signed an MoU with the Indian Banks’ Association for training programs on energy efficiency financing for scheduled commercial banks. This training program was launched in June 2015 and two training-of-trainers workshops were held in June 2015. During the launch of this training programme the BEE released a booklet entitled, “Success Stories for EE Projects Financed in India” and a “Training Manual for Energy Efficiency Financing in India”. This booklet containsan account of 50 success stories related to energy efficiency projects financed by SDBI and covers 20 industrial sectors across the country. In National Energy Conservation Awards 2015, two new categories for FIs and best business models were also introduced to encourage financing in the energy efficiency sector.

These financing tools for promoting energy efficiency projects under NMEEE will assist India in its commitment to the Paris Climate Change Agreement signed in December 2015.

Technology gap assessment of the Pulp and Paper Sector and the scope for UK technology suppliers in this industry

In India, six hundred pulp and paper manufacturing plants produce 14.99 million tons of paper against an installed capacity of 19.27 million tons. This accounts for 3.7% of the global paper production. The Indian paper industry has a highly fragmented structure consisting of small, medium and large paper mills with capacities ranging from 10 to 1500 tpd, and using mostly wood, agro residues and recycled waste paper for raw material. The industry is growing at a rate of 8% per annum, due to a demand for paper and paper board.

The Indian paper industry mostly produces writing/printing, newsprint, as well as industrial grade paper. Of the total production of 14.99 million tons of paper/paper board and newsprint, 35% is writing

and printing paper; 55% is packaging paper, and 10% is newsprint. Certain special kinds of papers such as security and cheque paper are imported. The writing and printing grades of paper,mostly the uncoated varieties, cream wove, maplitho and branded copier, are made mostly from wood-based raw materials, with agro and recycled waste paper being used as raw material for a small portion. Industrial paper, classified into kraft paper, white board, machine glazed (MG) poster, duplex board and grey board, is largely produced by the small- and medium-sized recycled waste paper and agro-based mills. Newsprint grade paper is made by mills which use mostly recycled waste paper as raw material.

The level of technology used in the three segments of industry (in terms of the raw

material used: wood, agro and recycled fibre-based) varies. The agro and recycled paper mills still use conventional processes which are obsolete by international standards, and have not attempted to improve their methods. However, the wood-based mills have upgraded the technology used to improve paper quality and reduce pollution load. In order to solve many problems the industry faces, it is necessary to modernize the processes involved in paper manufacture; the technology currently in use lags behind that used in the rest of the world by about 30 years.

Steps aimed at filling the gaps in technology should be taken up in wood, agro- and recycled fibre-based paper mills through a structured technology support

Interventions of ESCO-based Steam Supply Services in a Process Industry - the Success Story of Kaleesuwari Refi nery (KRPL)

Kaleesuwari Refi nery Private Limited (KRPL), popularly referred to as Kaleesuwari is one among India’s largest FMCG brands and has also managed to makea mark in a few international markets such as America, Europe, the Middle East and Asia.The refi nery produces edibleoils as also oils for home care, personalcare and for use in baking confectionery. There are four major manufacturing facilities across the southern states backed by state-of-the-art refi ning technology and processes from Desmet Ballestra, Belgium.

This is a case study of the KRPL unit located at Medavakkam, Chennai, and looks at their unique and innovative Energy Saving Company (ESCO)contract approach for eff ectively and effi ciently meeting the need for thermal energy.

Nature of Energy Use – KRPL ChennaiThe Chennai unit of KRPL is considered the mother unit and is highly energy in tensive.Electrical energy is sourced from the State Electricity Board while thermal energy is generated in-house using a coal-fi red boiler. Coal-fi red thermic fl uid heaters are also used to meet any high temperature heating process requirements.

Challenges Encountered with respect to in-house Thermal Energy GenerationThe current set up for supplying thermal energy involves the deployment of technically qualifi ed manpower as also top management for day-to-day activities such as procuring coal of the right quality,its storage, handling, utilization, operation and maintenance of the boiler and it sauxiliaries. Stringent statutory and environmental compliance by the company call for close monitoring and prompt action.

Intervention of GSH GROUP in Thermal Energy Supply Considering the challenges involved in fulfi lling their thermal energy needs, KRPL decided to outsource the operations and maintenance of their thermal utilities so as to enable a sharper focus on their core activities such as innovations in processing, launching a wider variety of products, and, maintaining an uncompromised quality standard.

The GSH Group, with their domain expertise in the operation of thermal utilities was a natural choice for this work, for KRPL.

GSH Group PLC,a renowned US- and UK-based multinational company in the fi eld of facility and energy management evolved the concept of steam supply service through ESCO contracting.

GSH has articulated a unique ESCO model in the Indian context. The model is a blend of GSH’s international experience and exposure as well as the specifi c requirement of Indian industries. In essence, the end-to-end responsibility of steam generation would be taken care of solely by the GSH Group with payment being made on a pre-agreed unit cost of steam.

Salient Features of Steam Supply Services via ESCO Route

The salient features of the steam supply model are listed below.

• GSH to take entire responsibility of steam generation including aspects

such as coal procurement, operations and maintenance of boiler and related auxiliaries, water treatment and waste disposal.

• Cost of steam indexed with price of coal based on prevailing market situation.

• Guaranteed supply of steam @ 14 ± 0.5 kg/cm² and 180 °C, and mass fl ow rate as desired.

• Uninterrupted steam supply throughout the day and year (excluding annual maintenance hours).

• Replacement guarantee for boiler and associated equipment throughout the period of the contract. Onsite maintenance of all the equipment. Duration of the contract 7 years from the signature of the contract and extendable by 5 years.

• All assets of the thermal utility leased to GSH Group for the term of contract.

Unique Strategies Adopted by GSH

To fulfi l the contract responsibilities and commitments, GSH adopted innovative engineering and managerial techniques. These are described below.

The technical team is supported by skilled technical staff and often trained by a team of technical experts and specialists.

iii. Advanced Automations and Instrumentation Controls

GSH has invested a considerable amount of capital in upgrading the metering and monitoring methodologies and are thus able to identify bottlenecks in day-to-day operations and eliminate the wastage of resources such as coal, water, electricity, etc. Some notable changes were the installation of online combustion monitoring software, EffiMax 3000 (a product of Forbes Marshall), and remote energy monitoring software, GSH EMS (a product of GSH), (shown in Figures 2 and 3) to monitor energy use and facilitate maintenance of desired efficiency levels.

iv. Energy EfficiencyThe main goal of this ESCO model is to fulfill the thermal energy demand of KRPL, Chennai, by enhancing the efficiency of energy use without compromising on environmental norms. The energy efficiency of steam generation is enhanced through the necessary audits and periodical reviews by the team of energy experts led by a specialized arm of the GSH Group. Different ways in which energy efficiency was increased and some areas of the utility where these improvements took place are listed below.

Efficient coal stacking and conveying.

Control of coal fines by monitoring quality and characteristics before feed.

Oxygen trim control (maintained at 4 to 5%).

Reducing radiation losses by cost-effective insulation.

Minimizing air ingress.

Recovering condensate to maximum possible extent thereby increasing feed water temperature and conserving resources.

Benefits of ESCO Model on Energy, Economy and EnvironmentThis ESCO contract commenced in April 2015 and continues to operate successfully. Benefits of the venture are detailed below.

Reduction in coal consumption maintaining a steam-to-coal ratio not

less than 5 kg of steam/kg of fuel.

Increased profitability, since energy efficiency is the only profit margin factor for the GSH Group.

Uninterrupted supply of steam with the desired parameters, hence increased productivity and nil downtime.

Sharper focus by KRPL team on their core activities such as production and quality enhancement to increase competitiveness in the market.

Reduction in operating costs because of improved energy efficiency and enhanced maintenance.

Watch by GSH on subsidies, environmental standards, CO2 quota management, hygiene and safety, etc.

SummaryThe scheme to supply steam through the ESCO route proved to be a success allowing the reaping of substantial financial, organizational and environmental benefits. The success of this ESCO model can be attributed to the unique work culture of the GSH Group and the extraordinary organizational support provided by the Kaleesuwari Group. The success of the ESCO model is also evident from the fact that a similar contract(ESCO-baseds team supply service at the KRPL, Palani Unit) was offered to the GSH Group by the Kaleesuwari management,an acknowledgement of the excellent service delivered.
