NESO Business Plan Guidance: decision

National Electricity System Operator (NESO) will need to submit a Business Plan for its enduring regulatory framework, commencing with the business plan cycle starting on 1 April 2026.

In May 2025, we consulted on NESO’s Business Plan Guidance. This document provides guidance on the information that should be included in NESO’s Business Plan. We consulted on the content of NESO’s Business Plan Guidance in accordance with Part D of Condition G1 of NESO's licences.

We received 14 responses to our consultation. We have set out our decision and rationale in response to stakeholder responses in our Decision on the enduring regulatory framework for NESO document.

NESO’s Business Plan Guidance will go live from 22 August 2025. The Business Plan Guidance document below is tracked to show the location of modifications relative to the previously published version. The clean version is available at: NESO Business Plan Guidance.
