Future reserve services

As the UK moves to a low-carbon economy, the way we operate the electricity system is evolving.

A smart, flexible system that makes the best use of all the energy resources available will enable us to meet our customers’ needs in a balanced, efficient and economical way.

Our aim is to create balancing services markets that meet our changing system needs, and in which all technology types can compete on a level playing field. To achieve this, we will:

  • provide market information that plainly sets out our needs;
  • simplify our products to create transparency; and
  • ensure routes to market for all participants.

We will publish updates on services and system needs via this page. We are keen to understand your views. You can get in touch with us to provide your thoughts and feedback at [email protected]. If you would like to be kept informed, please sign up to the mailing list using the link on the right.

Reserve Reform

Update - 18 December 2020

The Reserve Reform project aims to deliver a standardised suite of upward and downward reserve product(s) that work holistically with new frequency response products and reserve replacement products (TERRE and MARI) and can be procured at day ahead through an auction held on the Single Market Platform from March 2022.

We are co-creating this product with industry and hosted a workshop on the 9 December 2020 to communicate the need for reserve, and NESO’s drivers when designing a product suite and market. We also wanted to understand the industry’s needs and drivers​, share ideas to facilitate co-creation of a new reserve product suite and identify common themes and areas for further investigation.

You can view the slide deck and feedback on the four topics from the workshop below:

Operability Strategy Report

Update - December 2022

We have updated our Operability Strategy Report which outlines the future operational challenges we face, driven by decarbonisation of the electricity system. It defines the operational requirements, future system needs, and capabilities required to enable a zero carbon electricity system by 2035. It also covers our progress towards meeting our ambition to be able to operate the network using 100% zero carbon electricity by 2025.

Flexibility from Intermittent Generation

March 2020

In this report we provide an overview of our current markets and the barriers that we are aware exist for intermittent generation types, along with the work that we are doing to increase access to our markets for this specific technology group. With these enablers we hope to increase competition, unlock consumer value and facilitate open and transparent markets. These are some of the deliverables that we have committed to as part of the NESO Forward Plan, and we will be continuing to report progress through the monthly and quarterly Forward Plan progress reports.

Response and Reserve Roadmap

December 2019

This document updates our plans for the reform of our frequency response and reserve services.  It is our priority to reform the design of these services to ensure that they are capable of supporting the operation of the electricity system carbon-free by 2025. This document gives an update on the progress made since the publication of our 2017 System Needs and Product Strategy (SNaPS) document, the service-specific roadmaps, the NESO Forward Plan and initial publications on the service designs.

Reserve Reform Q&A

Update - 25 February 2022

On 25 February, we shared an update on Reserve Reform project delivery. We will not be launching Negative Slow Reserve directly after Dynamic Moderation in Summer 2022, and instead we will be taking the time to further engage with industry to identify the optimum approach to deliver the new reserve products.

Update – 14 September 2021

Following the co-creation workshops and an internal challenge and review process, we will deliver Negative Slow Reserve as the first service in the new suite of Reserve products. This update summarises the progress made thus far on Negative Slow Reserve and provides an update on other Reserve services.

Reserve Reform Product & Service Design

Update - 4 March 2021

We are co-creating the new reserve product suite with the industry, and this consultation aims to gather industry views on initial product designs which have been based on feedback from the industry workshop on 9 December 2020.
