Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what recent assessment he has made of the role of battery storage in reducing renewable curtailment.

Electricity storage has an important role to play in decarbonising the power sector by helping to balance the electricity system at lower cost. Electricity storage achieves this by charging when electricity is abundant and discharging when it is scarcer, thereby mitigating the need for grid reinforcement and reducing the curtailment of renewable generation. Efficient use of storage therefore offers opportunities for reducing constraint costs. The Government, the National Energy System Operator (NESO) and the Office of Gas and Electricity Markets (Ofgem) are currently investigating options aimed at maximising the benefits of storage technologies in reducing system costs.
