1 Energy Analysis with SAP MII

1.1 Solution Overview

SAP is delivering preconfigured, best practice templates for the solution SAP ManufacturingIntegration and Intelligence (http://www.sap.com/solutions/manufacturing/manufacturing-intelligence-software/index.epx). Energy Analysis with SAP MII is the result of a successful co-innovation project, leveraging the experience of SAP and partner experts from RTS Inc., as wellas customer and industry input.

Energy Analysis with SAP MII is designed to help organizations manage energy use and costand allow them to develop sustainable green strategies. This software solution is tightlyintegrated into the clients existing systems for process monitoring and control. The applicationprovides information to the appropriate personnel within an organization to improve energyefficiency and reduce carbon footprint within the enterprise.

Characteristics and Benefits:Performance of Energy Consumption Reporting and Visualization makes data useful to enable acontinuous energy improvement plan

Allows Energy Analysis Comparisons & Cost Allocationo Production shifts, lineso Departmentso Significant assets

Granular Energy Consumption Visibility ~ 15min intervals Early detection of poor Energy Performance Support Budgeting & Management Accounting Shadows Utility Meters, avoids the need of utility billing reconciliations Helps avoid peak demand charges by providing immediate alerts Can be deployed as a standard solution across all plants and sites, regardless of

underlying production and IT systems Monitors overall plant demand

Energy Analysis with SAP MII consolidates all energy related data (sources, costs, control andmonitoring points) into a data layer and provides tools to access and interact with the data. Whileconceptually straightforward, today’s energy analysis systems mostly lack that kind of capability.It is worth noting that Energy Analysis with MII is not a control system and should not beconfused with building automation systems (BAS) or a Manufacturing Execution System (MES).Energy Analysis with SAP MII is broader in scope than control systems, reaching well beyondboth BAS and MES. It provides data collection, data access, diagnostics and monitoringcapabilities, a historical data storage, and a lot more as detailed throughout this paper. Similarly,EMIS should not be confused with utility billing systems. It encompasses billing and meter data,but extends beyond and connects billing information directly to the related operational data.Energy Analysis with SAP MII provides actionable insight through the consolidation of data fromall of the institution’s disparate energy and building management systems and the interactiveaccess to that data, providing the facility’s operations and engineering departments with anaccurate picture of operations. With facts in hand, they can steward their assets, lower totalenergy consumption and operational costs quickly and effectively, and have the ability to verifyand measure results.The starting point is the flexible Executive Overview that displays the global energy status.

Executive Overview Charts display the six months history of the selected site consumptionvalues against the consumption target values in the system in a Bar chart. Further, it allows ,consumption and cost comparisons per production unit comparing all the sites.Energy Analysis displays the meter consumption values against the meter consumption targetvalues in the system in a report format for all or a particular group (location and/or asset), as wellas individual meters on that group. This provides the facility for the user to select the locationand unit of measurement and the date range.Meter Readings that provides ability to manually update the meter readings for all meters in thesystem. User can add, modify or delete the records for the selected meter. A push button willallow user to create notification to verify the reading values.

Delivering simplified user interfaces, preconfigured business processes and content, as well asfull installation and user documentation, Energy Analysis with SAP MII templates are designed toreduce implementation cost, effort and risk. Companies can thus leverage existing investments,and profit from lower total cost of ownership and time-to-value.

To ensure SAP customers and partners can leverage these templates two documents areprovided:

A technical guide that supports the implementation. It describes technical aspectsneeded to set-up Energy Analysis with SAP MII and implement the templatesAn application guide – this document - covers the documentation of all functions andfeatures of the templates as well as a user guide

2 Business Conditions

The functions described in this Application Guide are part of a larger chain of integrated businessprocesses or scenarios. As a result, you must have completed the following processes andfulfilled the following business conditions before you can start any activities in this scenario:

Business Condition Scenario

You have decided the location of all meters andsensors. You have decided on additional metering ormeasurement (if any). You have decided what type ofmeters to use units of measure.

Prerequisite Define Time IntervalReading for Consumption DataPrerequisite Develop the Meter list.

You have decided and assigned the energyaccountability centers (groups), with requiredgranularity (down to plants, lines, assets).

Prerequisite Develop the Groups list.

2.1 Prerequisites

2.1.1 Define Time Interval Reading for Consumption DataThe best option for collecting consumption interval data is for the meter to provide the datadirectly at regular intervals, or to attach a reading device that can provide the consumption datato Energy Analysis with SAP MII. The application must understand and track the hierarchy ofmeter data that comes from a purchased utility. The data hierarchy goes from utility type, tosupplier, to account, to meter and rate. A single rate is typically used for multiple metersspanning multiple accounts.

Optimal Time IntervalThere are a number of considerations in selecting a standard time series interval used by EnergyAnalysis with SAP MII, the most significant of which is ensuring that it is able to display sufficientdata to identify transitions—this means that there should be enough data points gathered todiscern performance fluctuations across transition time periods such as between day and night,‘office hours’ and nonworking hours, etc. With this information, behavior patterns and problemsbecome apparent quickly. For this reason, and because electricity is frequently metered withinthe same time interval, 15 minutes is a proposed appropriate time series upon which data can benormalized. Longer intervals do not provide sufficient data granularity to always see behavioralchanges. Shorter intervals can increase the data storage and processing requirements by 300%(or more) while increasing the information value very little. Additionally, because capturing dataat 15-minute intervals does not require a great deal of storage space to house the data records,data can be stored for the lifetime of a piece of equipment—20 years or more.The time interval defined here is used to schedule the SAP MII transaction acquiring the datafrom the meters, in the SAP MII schedule editor. See the Configuration guide on how the timeperiod schedule is set up.

ElectricityToday most electric utilities quantify consumption by averaging the demand over a 15-minuteperiod (standard interval). The majority of electric utilities make the interval data availableelectronically to the customers, although again, not always in convenient ways to collect it. Both15-minute average demand and month-to-date consumption are required for Energy Analysiswith SAP MII. Similarly, electric bills with determinants must be stored in the database too (for


© SAP AG of 22

reasons discussed later) and, because billing rates change over time, it is important that EnergyAnalysis with SAP MII can accommodate this dynamic data and propagate these adjustments.Natural GasDue to the fact that natural gas utility companies rarely bill based upon readily obtainablestandard time intervals (a fact which has led many institutions to install their own gas meters tovalidate billing), it is important that the natural gas meters installed throughout the site areconnected to the automated metering or building automation system for data collection. It is alsocritical that the meter configuration and BAS / MES point configuration collect running totals ofconsumption flow, etc. as well as instantaneous readings. Running total data is required to makeit possible to reconstruct the inevitable gaps and missed readings.Chilled WaterWhile many organizations generate their own chilled water for air conditioning, etc., some chilledwater is purchased from third-party utility companies. Similar problems exist concerningmetering, again leading some organizations to purchase their own meters to validate bills.Because chilled water generation is tied to electric consumption, suppliers are increasinglymoving towards more accurate time-series billing.SteamLike chilled water, steam is often produced by an organization itself, but, when purchased, it istypically billed based upon time intervals ranging from 15 minutes to one hour.

2.1.2 Develop Groups ListOrganizational InformationOrganizational information is required for Energy Analysis with SAP MII, so that it can roll up costcenter information. Once Energy Analysis with SAP MII allocates costs to each space,organizational information is required that can relate space to department (or cost center). It isincumbent upon Energy Analysis with SAP MII to adapt to any hierarchical structure and to theconstantly changing organizational structure of the institution. Energy Analysis with SAP MIIshould not burden the space management system or the personnel maintaining space planningdata with this task. In essence, Energy Analysis with SAP MII increases the value of theinvestment already made in existing space planning systems.Space Planning DataSpace planning data are required by Energy Analysis with SAP MII in order to identify energycosts at the space level. Space planning systems (SPS) contain information concerning the useand allocation of all areas within a campus or facility. They map the hierarchy of the campus bysite, zone, building, floor and room. Space planning systems also understand the relationshipsbetween space and cost centers. Both SPS and Energy Analysis with SAP MII have distinct,complementary roles. Space Planning’s role is to maintain the space relationships (sinceoccupancy and cost centers change) and to transfer cost center information into the generalledger. The role of Energy Analysis with SAP MII is to deliver accurate energy costs down to thespace level where the SPS can roll up the costs by cost center.

Naming ConventionsThere is a complete lack of uniformity in how buildings and systems are labeled within aninstitution. Today’s facility organizations use building automation systems, store utility bills andmeter readings in Excel or some utility system, generate their own utility bills for steam andchilled water, create campus maps and engineering drawings, maintain space planning systems,and work with outside engineering and construction firms. Each group has their own systems forspecific tasks, each with a different nuance to the same information. This is unlikely to beprevented or be brought under control - hence Energy Analysis with SAP MII should be able topresent to each specific user group the naming convention they are familiar with, while providingthe cross reference information required.

ekWh Factor This is the numericinput of equivalentkilowatts hour (EMISunit of energy) for theselected or new unit ofmeasure.

User has to input theekwh factor (decimalvalue) (i.e. selected /new unit of measure = Xekwh)

Numeric value, decimalsallowed. The EMISdatabase stores onlyequivalent kilowatt hoursenergy values for alldefined meters.

Add Button Allows the user to add new record-sets into the system (units of measureand characteristic information)

Update Button Allows the user to update existing record-sets into the system (units ofmeasure and characteristic information)

Delete Button Allows the user to delete record-sets into the system (units of measure andcharacteristic information)

It is possible to include currencies as units of measure. In this case, the ekWhFactor will reflect how many kWh can be bought by one unit of currency. The energyreporting screen allows selection of each defined unit of measure, so that consumptionand targets for groups and/or meters can be expresses in the selected currency.

3.8 Groups Configuration

3.8.1 UseGroups Configuration allows the user to see the entire set of meter groups (locations) availablein the system. The user can update their names and hierarchical relationship or delete them.

For reporting purposes it is required to define a specific meter group for eachlocation (e.g. plant) defined in the master data. Within a meter group, all consumptionand target values for each individual monitored energy meter or defined sub-group ofmeters are rolled up into the parent group.

A sub-meter (i.e. meters defined with a parent meter) consumption and/or targetvalues are not summed up into the parent group, since the corresponding values arealready included in the readings from the parent meter. Sub-meter data is mainly usedfor energy balance calculations and/or determining the overall energy loss within theenergy distribution and/or energy generation system.

3.8.2 Procedure1. Under Configuration tab click on then Groups tab. The meter groups (locations) are

displayed in the Meter Groups Display area.2. Click on a meter group (location) meter group in the Meter Groups Display area. The Input

Panel area displays details of the selected meter group (location).3. To change the details, change the content of the corresponding field, and press the Update
