GRIDCO, Odisha’s renewable energy nodal agency, has issued a Request for Proposal (RFP) to appoint a consultant for an Environmental and Social Impact Assessment (ESIA) of the proposed 225 MW Upper Indravati Floating Solar Photovoltaic and battery energy storage system (BESS) project. The development, including power evacuation infrastructure and transmission lines, is planned across Nabarangpur and Kalahandi districts. The consultancy will assess the project’s environmental and social impacts under applicable Indian regulations, the International Finance Corporation Performance Standards 2012 and World Bank Group Environmental, Health, and Safety Guidelines.
