INDIAN POWER SECTOR
OVERVIEW
CLEAN COAL DAY 2016 INTERNATIONAL SYMPOSIUM (TOKYO)
PRESENTION BY:
ANIRUDDHA KUMAR JS(THERMAL), MIN OF POWERGOVT OF INDIA
INDIAN POWER SECTOR OVERVIEW
India has a Federal political structure
Power is a concurrent subject
Till recently, very few private sector plants, transmission constraints
Electricity Reforms-Electricity Act 2003
De-licensing of Generation, tariff determination by competition
Unbundling of Generation, Transmission and Distribution
Corporatisation
Setting up of independent Regulators and Appellate Tribunal for dispute resolution

INDIA AIMING FOR REDUCTION IN EMMISSIONS IN POWER SECTOR
Commitments made by India in COP 21: Reduction in the emissions intensity of its GDP by 33 to
35 % by 2030 from 2005 level.
To achieve about 40 percent cumulative electric power installed capacity from non-fossil fuel based energy resources by 2030.
INDIA AIMING FOR REDUCTION IN EMMISSIONS IN POWER SECTOR
Steps Taken Introducing new, more efficient and cleaner technologies in
thermal power generation: no sub-critical plants allowed. 40 units of 27485 MW capacity commissioned 61units of 41865 MW capacity under construction
New emission norms for Thermal Power Stations issued by Ministry of Environment, Forest and Climate Change in December 2015 regarding Suspended Particulate matter (SPM), SOx, NOx, Mercury and specific water consumption.
Energy efficiency measures175 GW of Renewable Power by 2022
CHALLENGES…………
Grid Stabilisation in the context of integration of Renewable Energy Sources
Flexible Operation of Thermal Units
Retrofitment of existing plants to meet new emission norms
