Existing services
Demand Flexibility Service
This innovative new service offers incentives for flexing the times when consumers use electricity, helping us to manage the electricity system during peak demand.
Frequency response
We ensure there is sufficient generation and demand to control system frequency. Services include new Dynamic Response, Mandatory Frequency Response and Firm Frequency Response.
Reserve services
These services provide us with access to sources of extra power when it's needed the most. Our reserve services are designed to deliver power across a range of timescales.
Local Constraint Market
We are exploring the development of a new Local Constraint Market to access new sources of flexibility to help manage one of our most constrained boundaries.
System security services
Read about the techniques and services we use to help maintain the security and quality of electricity supply across Britain's transmission system.
Reactive power services
These services help us ensure voltage levels on the system stay within a specific range. We instruct generators or other asset owners to either absorb or generate reactive power.
Trading
Access trade information data, trading instruments and requirements for trading.
Electricity System Restoration Standard
A successful path to zero carbon necessitates changes to our existing Electricity System Restoration preparation arrangements.
Network services procurement
Network services procurement projects aim to find solutions to the challenges of the electricity system with increasing renewable and low carbon generation.
Stability market
The Stability Markets allow NESO to secure operation of the network at lowest cost to consumers.
Future services
