Energy Supply

The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of Ofgem’s RIIO-GT3 Draft Determinations on energy security.

Answered by Michael Shanks

DESNZ works closely with the energy sector to maintain energy security and ensure industry has the tools at their disposal to support security of supply.

As the risk landscape continues to evolve, ensuring high standards of infrastructure resilience and security across the energy sector is a key priority for the Department and Ofgem.

The Department will continue engaging with the regulator to ensure RIIO-GT3 delivers the investment needed to maintain energy security and resilience through the price control period.

For example, DESNZ recently launched an Energy Security and Resilience Taskforce with CEOs of critical operators, with Ofgem in attendance, which will be a key forum to discuss risks and standards.
