Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the effectiveness of battery storage technology for large-scale grid stabilisation.

Battery energy storage systems can play an important role in large-scale grid stabilisation, depending on the type of inverter technology used and their location on the network. The National Energy System Operator (NESO) is responsible for grid stability, and the department works with NESO to ensure that we have the resources needed for secure system operation. Battery energy storage systems with grid-forming capabilities were trialled on the Stability Pathfinder programme and are now eligible to apply into the Stability Market which offers a route for NESO to procure these services through a transparent and competitive market.
