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.

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.

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.

1. Study of load profile and improvementof efficiencies Developing and promoting energy efficienttechnologies, Adopting soft options like higher prices during peakhours, concessional rates during off-peak hours

seasonal tariffs, etc.

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.

8/13/2019 Energy Audit 08.03

CEETEM-COS

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.

8/13/2019 Energy Audit 08.03

CEETEM-COS

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.
