Key Takeaways
- India will mandate two-hour battery storage for all new solar and wind projects starting July 2027.
- The storage requirement will increase to four hours by July 2029, maintaining a minimum capacity of 10%.
- The regulations aim to address challenges in managing electricity generated from renewable sources.
New Regulations for Renewable Energy Projects
India is set to implement new regulations that require all new solar and onshore wind projects to include battery storage. Starting July 2027, these projects will need to have battery storage that can hold energy for at least two hours, equivalent to a minimum of 10% of the project’s capacity. This requirement is part of draft regulations put forth by the Central Electricity Authority to improve the management of renewable energy and its fluctuations.
The purpose behind these regulations is to ensure that surplus energy generated from renewable sources can be stored and reused effectively. This initiative comes as India, the third-largest solar power generator globally, faces difficulties in managing excess solar energy. Notably, nearly 14% of the solar output was curtailed between April and June due to an abundance of clean energy during the day and insufficient transmission infrastructure.
In addition to the battery storage mandate, the draft rules will also require all clean energy projects commissioned after July 2027 to integrate grid-forming inverter capabilities. These technologies are vital for stabilizing voltage and frequency in the grid, particularly as the proportion of renewable energy rises. By establishing these regulations, India is taking significant steps to enhance the reliability of its power supply while facilitating the transition to a more sustainable energy future.
The planned regulations are designed not only to improve energy storage but also to help manage the challenges arising from the intermittent nature of solar and wind energy generation. As the country continues to increase its renewable energy capacity, these measures are intended to ensure that power can be effectively dispatched when needed, minimizing adverse impacts on the grid and supporting broader sustainability goals.
