Renewable Energy: Finance

Question

To ask the Secretary of State for Energy Security and Net Zero, what steps he is taking to reduce constraint payments to renewable energy producers.

Answer

The majority of the costs of constraints are driven by turning on expensive gas plants to replace curtailed generation. The current extent of grid constraints reflects years of underinvestment, with new network infrastructure development having lagged the expansion of new generation.

We are already taking action to reduce constraints, with the biggest upgrade to Great Britain’s electricity network in decades, which will also help deliver clean power by 2030.

Upgrading the grid is not a choice, it needs to happen to make sure the grid stays resilient and to get power from where it is generated to where it is needed, so we can connect homes, businesses and industry to generate growth.
