National Mission for Enhanced Energy Efficiency (NMEEE)
- 2010
Four initiatives to promote energy efficiency
Perform Achieve and Trade Scheme (PAT), a market based
mechanism to enhance cost effectiveness of improvements
in energy efficiency
Market Transformation for Energy Efficiency (MTEE),
Energy Efficiency Financing Platform (EEFP),Framework for Energy Efficient Economic Development (FEEED),

Performa , Achieve and Trade PAT
( To be implemented from 01.04.2011)
PAT framework includes:Methodology for setting SEC for each DC in the base line year
Methodology for setting the target to reduce SEC by the target year
The process to verify the SEC of each DC in the base line as well astarget year by an accredited verification agency
The process to issue energy certificates to those DCs who achieve SEC
lower than the specified value
Trading of ESCerts
Compliance and reconcilation of ESCertsCross sectoral use of ESCerts and their synergy with renewable energy
certificates

As per the Energy Conservation Act,2001, Energy Audit is defined as
Theverification, monitoring and analysis of use of energy
including submission of technical report containing
recommendations for improving energy efficiency with
cost benefit analysis and an action plan to reduce energy
consumption.

An Energy audit will help to keep focus on
1. Details of energy consumption
2. Energy costs,
3. Specific energy consumption
4. Energy saving potential areas,
5. Saving measures suggested
6. Cost economics of new technologies, retrofit for existingequipments

Energy Audit also provides
1. Bench-mark (Reference point) for managing energy in the
organization
2. Basis for planning a more effective use of energy
throughout the organization.

Demand Side Management
Actions of an utility, beyond thecustomer's meter, with the objective ofaltering the end-use of electricity
be it to increase demand, decrease it,shift it between high and low peakperiods, or manage it when there areintermittent load demands - in theoverall interests of reducing utilitycosts.

DSM is the implementation of those measuresthat help the customers to use electricitymore efficiently and in doing so reduce thecost to customers.

Demand Side Management
Often the terms energy efficiency and DSMare used interchangeably. However, it is important to point out that
DSM explicitly refers to all thoseactivities that involve deliberateintervention by the utility in themarketplace so as to alter the consumer'sload profile.

Demand Side Management
To make this distinction precise,1. A program that encourages customers toinstall energy efficient lighting systems
through a rebate program would fall underDSM.2. On the other hand, customer purchases ofenergy efficient lighting as a reaction tothe perceived need for conservation is notDSM but energy efficiency gains.

Demand Side Initiatives -Deliberations at
the Forum of Regulators (FOR)
DSM involves actions at the level of consumers.
Constitution of DSM Cells by all DISOMs
Submitting of DSM Plans by Discoms including measures
for increasing the consumer awareness
Organizing of training courses on DSM by FOR Allowing cost of approved DSM programmes as pass
through in ARR.

Recommendations of Forum of Regulators
(FOR) on Demand Side Initiatives
SERC to specify a percentage of the ARR to be
utilized for DSM programmes
SERCs could consider appropriate tariff interventions
to support DSM eg. TOD tariffs, power factor
incentives and penalty, reactive power charges, load
management charges, rebate incentives for energy
efficient buildings/appliances, and differential pricing
for agriculture consumers.

Recommendations of Forum of Regulators
(FOR) on Demand Side Initiatives
Special tariffs to induce the concerned authorities
towards DSM & Energy Efficiency
SERCs could consider giving a slightly higher return
on equity for the investments made towards DSM
measures.
