In April 2021 new RIIO-2 price controls came into effect which 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, which was updated for the second Business Plan period (BP2, starting on 1 April 2023).
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:
- Plan Delivery (completing the activities set out in the Delivery Schedule)
- Metric Performance (please refer to the metrics set out by Ofgem in annex 1 of the ESORI guidance)
- Stakeholder Evidence
- Quality of Outputs (which replaced Demonstration of Plan Benefits from April 2023)
- Value for Money
In line with Ofgem’s ESORI guidance which was updated for BP2 in March 2023, we publish a report on this page every month. The reports vary in their contents and significance:
17th working day
An update on monthly Metrics and Regularly Reported Evidence, and notable activities from the last month.
We also publish the minutes of our monthly performance meetings with Ofgem
Q1: 17th working day of July
Q3: 17th working day of January
In addition to the above, Quarterly reports provide an update on quarterly Metrics and Regularly Reported Evidence.
They also include a Value for Money update on cost and delivery progress of all ESO specific IT investments, and an updated Deliverables Tracker.
|Mid-year reports||17th working day of October||In addition to the above, Mid-year reports provide an update on six-monthly Metrics and Regularly Reported Evidence. The Value for Money section provides an additional update of progress at an overall Role level, and we also publish results of stakeholder satisfaction surveys.|
|Mid-scheme and End of scheme reports||7th May||
In addition to the above, these reports provide an update on annual Metrics and Regularly Reported Evidence.
They also report against the delivery schedule for each of the activities outlined in the ESO’s Business Plan CBA, and set out how activities are delivered in line with expectations set out in the ESO Roles Guidance.
The Performance Panel scores the ESO’s performance every six months, and Ofgem will decide on our financial reward at the end of the two-year “Business Plan 2” period (in summer 2025).
