NATIONAL MISSION ON

ENHANCED ENERGY EFFICIENCY (NMEEE)

The National Action Plan on Climate Change wasreleased by Honorable Prime Minister of India in June

2008

The Action Plan Outlines 8 Missions including NationalMission on Enhanced Energy Efficiency (NMEEE)


3/15

NMEEE. 4 new initiatives

The market based mechanism to enhance costeffectiveness of improvements in EE in energy intensiveindustries through certification of energy saving whichcan be traded. (Perform, Achieve & Trade) Accelerating the shift to energy efficient appliances in

designated sectors through innovative measures to makethe product more affordable

Creation of a mechanism that would help finance DSMprograms in all sectors by capturing future energy saving

Developing fiscal instruments to promote energyefficiency


4/15

Large Energy Usage Bandwidth

The energy usage pattern varies widely in industries of a particular

sector due to various diversities like

- Scale of Production (Installed Capacities)

- Use of Raw Material

- Process Technology

- Vintage of Technology - O & M Practices

- Type of Product Output etc.

Factors of Diversity Most Affected Sectors

a) Raw Material Input Pulp & Paper, Fertilizer, Power Plant, Textile

a) Quality of Raw Material / Fuel All sectors

a) Process & Technology Aluminium, Iron & steel, Chlor-Alkali, Paper

a) Final Product output Textile, Iron & Steel, Aluminium

a) Vintage All Sectors

a) Capacity Utililization All sectors

Target Setting of Power Plants for PAT Mechanism would mainly

depend upon Net Heat Rate (NHR) to include both i.e. GHR &

APC

Net Heat Rate = Gross Heat Rate / (1- APC%)

Example - 1 Installed Capacity = 420MW

Station Design Heat Rate = 2450 Kcal/Kwh

Annual PLF = 55.72 %

Annual Average Operating Station Heat Rate = 2650 Kcal/Kwh

Average APC = 9.7 %

Annual Production in MUs = 2050.28

Net Operative Heat Rate = 2936.29

Net Design Heat Rate = 2714.68

Deviation from Design NHR = 221.61

% Deviation = 8.16 Target % Reduction = 17% of Deviation = 17 % of 221.61= 37.67

Target NHR Reduction : 37.67 Kcal/KWh
