How we're performing under RIIO-2
Our RIIO-2 Business Plan

From April 2021 new RIIO-2 price controls will determine the amount we can earn for the projects we deliver and the services we provide.

On this page, you will find our performance reports, which form part of our evaluative incentive scheme.

What is an evaluative incentive scheme?

Under the ESO’s evaluative incentive scheme, a Performance Panel scores how well we have delivered the objectives set out in our RIIO-2 business plan.

Our regulator, Ofgem, then converts these scores into a financial reward or penalty.

The RIIO-2 framework divides the ESO’s activities into three roles:

  • Role 1: Control centre operations

  • Role 2: Market development and transactions

  • Role 3: System insight, planning and network development

The reports on this page perform part of the evaluation process, and provide a transparent summary of our activities.

How we report on our progress

The Performance Panel assesses our performance according to five criteria: 

  1. Plan Delivery (completing the activities set out in the Delivery Schedule)

  2. Metric Performance (please refer to the metrics set out by Ofgem in annex 1 of the ESORI guidance)

  3. Stakeholder Evidence

  4. Demonstration of Plan Benefits

  5. Value for Money

In line with Ofgem’s ESORI guidance, we publish a report on this page every month. The reports vary in their contents and significance:
