The question
To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of curtailment costs to electricity billpayers in 2026.
Answered by Michael Shanks
Data on the aggregate impact of curtailment payments to electricity billpayers is calculated by the National Energy System Operator (NESO) and can be found in NESO Annual Balancing Report, the next of which will be published later this year. The most recent NESO Annual Balancing Report was published in June 2025, covering the 2024/25 financial year, and can be found via this link: neso.energy/document/362561/download
