Derogation to Scottish and Southern Electricity Networks Distribution pursuant to SLC 13B Part E of the Electricity Distribution Licence
Share the page
We have granted a derogation to Scottish and Southern Electricity Networks (SSEN) to charge outside of its methodology for extra high voltage (EHV) customers for 2025/26. Specifically, it allows SSEN to carry over locational components and Network Use Factors of the 2024/25 charge setting process to the 2025/26 charging year. We consider it is in the interests of its customers overall, and in particular its EHV customers, to mitigate what would otherwise have been an exceptional level of volatility in charges and maintain the tariff notice period.
