Previous plans and documents

We are now preparing for the final RIIO-2 planning cycle, BP3, which will run from 1 April 2025 to 31 March 2026. As always, we are keen to work with a wide variety of stakeholders, NESO customers and consumer representative groups in a co-creative manner, to help shape our plans, where it is possible to do so. 

To help stakeholders understand the new format of BP3, and the Performance Objectives contained in the plan, we held a series of webinars. There was a single high-level kick off webinar, followed by four webinars that examine pairings of our Performance Objectives
