Techno-economic analysis of renewable energy round the clock (RE-RTC) supply for achieving India's 500 GW non-fossil fuel based capacity target by 2030

India’s ambition to achieve 500 GW of non-fossil fuel-based capacity by 2030 is steering the nation towards innovative solutions in renewable energy. With solar and wind power at the forefront, the variability and intermittency of these sources pose challenges to grid operations. To address this, the concept of Renewable Energy Round-the-Clock (RE-RTC) has emerged, combining renewable sources with storage systems like battery energy storage or pumped storage hydro (PSP) to ensure a steady power supply. A recent paper delved into the techno-economic analysis of various RE-RTC combinations, considering generation profiles, storage solutions, investment costs, and demand patterns. The goal is to provide reliable, cost-effective power while reducing greenhouse gas emissions.
