NATIONAL MISSION ON
ENHANCED ENERGY EFFICIENCY (NMEEE)
The National Action Plan on Climate Change was
released by Honorable Prime Minister of India in June
2008
The Action Plan Outlines 8 Missions including National
Mission on Enhanced Energy Efficiency (NMEEE)
NMEEE…. 4 new initiatives
The market based mechanism to enhance cost effectiveness of improvements in EE in energy intensive industries through certification of energy saving which can be traded. (Perform, Achieve & Trade)
Accelerating the shift to energy efficient appliances in designated sectors through innovative measures to make the product more affordable
Creation of a mechanism that would help finance DSM programs in all sectors by capturing future energy saving
Developing fiscal instruments to promote energy efficiency
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
