Coal based Thermal Power Plants (TPP) are the backbone of the power generation utilities in the country. Coal based TPPs constitute to around 56.1% of the total installed capacity and generates around 74.2% of the electricity generated in India. Considering the high pollution and resource impacts, of TPPs the Ministry of Environment, Forest and Climate Change (MoEF&CC) notified the Environment Protection (Amendment) Rules (EPAR) on December 5, 2015 with a two-year window for TPPs to meet these standards. When implemented, these norms are expected to have positive environmental and health benefits by leading to lower pollution levels from TPPs. However, compliance with the new emission norms would require retrofitting existing thermal power plants with various Pollution Control Technologies (PCT) in the form of auxiliary systems to control SO2, NOX and PM emissions. In order to ensure 24x7 supply of electricity, CPCB (in consultation with CEA) finalized the revised timelines for all TPPs to comply with the new emission norms by December 2022. The team at Energy and Environment Programme (EEP) in NIAS, Bangalore interacted with various Power Plant Generation companies (GENCOs) in Southern Region to understand their challenges and way forward with respect to the huge capital investment and schedules for implementation. This team developed and a “Concept Paper” for a workshop with the theme, “Strategies and Action Plans needed for transition to an environment friendly and sustainable Electricity Source mix for the Southern Region”. This Workshop was held at NIAS on 17th September 2019 to enable key stakeholders - Power Plant Owners (Central & Southern States), Pollution Control Equipment Suppliers, Regulators and Policymakers to share their experience and deliberate on the challenges to develop a road map for implementation. This report presents the gist of each talk by the invited participants, and also consolidates the key findings and recommendations of the Workshop. This summary report will form the basis for further research as well as for policy advocacy with GOI through NITI Aayog. A.V. Krishnan, Shyam Sundar R, Shilpa Srivastava and R. Srikanth
