GRID FLEXIBILITY

Value can depend on where the battery is connected.

National and local networks procure flexibility for different needs. A commercial battery may be useful when it can change import or export in the right place, at the right time.

Location, network need, metering and provider registration decide whether an opportunity is actually accessible.
01

Demand Flexibility Service

NESO's year-round DFS rewards eligible homes and businesses for changing consumption when the system needs support. From April 2026 it expanded to bidirectional flexibility, zonal procurement and a lower 0.1 MW threshold; businesses usually access it through a registered provider.

02

DNO and local flexibility

Distribution Network Operators procure flexibility in constrained areas to help manage local networks and sometimes defer reinforcement. Requirements are regional and can appear only at particular substations or times.

03

Constraint management

Flexibility can help when the network cannot move all available power across a boundary. A battery might charge when energy is abundant or discharge when local demand is tight, depending on the service and connection.

04

Check the route, not just the map

A postcode is a useful start, but participation can also depend on the MPAN, feeder, import/export permissions, baseline method, minimum volume and conflicts with other services.

  • DNO procurement
  • Regional constraints
  • Provider and aggregation access

PLAIN-ENGLISH FAQ

Questions commercial teams ask.

Is flexibility available everywhere?

No. Some national services are broad, while local services depend on a specific network requirement and connection location.

What is constraint management?

It changes generation or demand where network capacity is limited, helping operators keep flows within safe limits.

Can a battery join DFS and a DNO service?

Possibly, but primacy, baseline and stacking rules are designed to prevent conflicting instructions. The current service terms must be checked.
