How Battery Energy Storage Systems Can Improve Renewable Power Grid Stability
India's power sector is undergoing a major transformation as solar and wind capacity continues to grow. Renewable energy supports the country's clean-energy goals, but its variable generation creates new challenges for power-system operators. Solar generation changes with sunlight, while wind generation depends on weather conditions. Maintaining a balance between electricity generation and demand therefore requires flexible grid infrastructure. Battery Energy Storage Systems (BESS) are becoming an important part of this transition. By storing electricity when renewable generation is high and supplying it when generation falls or demand rises, BESS can improve grid flexibility, support frequency and voltage management, reduce renewable-energy curtailment, and help integrate more clean power into the electricity network. The Central Electricity Authority has also highlighted energy storage as an important requirement for addressing the intermittency of renewable energy and suppo...
