The document discusses India's power grid and integration of renewable energy. It notes that renewable energy capacity in India is currently 44 GW and plans to reach 175 GW by 2022. This growth presents transmission challenges due to the intermittent nature of renewables. The Power Grid Corporation of India is addressing this through initiatives like green energy corridors to strengthen transmission infrastructure, renewable forecasting centers, battery storage pilots, and enabling policies around ancillary services. The corporation's vision is for a flexible grid that can smoothly integrate high levels of renewable capacity through advanced technologies and system upgrades.
