UK Local Flexibility Markets: An Overview

Unlocking the power of decentralised energy to create a smarter, greener, and more resilient grid for the future.

What is a Local Flexibility Market?

Imagine the electricity grid as a road network. Traditionally, large power stations pushed power out in one direction. However, with the rise of renewables like solar panels and new demands from electric vehicles (EVs), we now have energy flowing in multiple directions, creating "constraints" or traffic jams on local networks.

A local flexibility market is an innovative solution where local grid operators (Distribution Network Operators, or DNOs) pay businesses and households to briefly change their energy usage—either by reducing demand or exporting stored power—to help balance the network. This is far cheaper and faster than building new substations or laying more cables.

Explore Demand & Flexibility

Understanding the potential flexibility from aggregated household demand is crucial. Use our new GB Household Demand & Flexibility Tool to model demand shapes and simulate the revenue potential of residential batteries in local markets.

How It Works: The Aggregator's Workflow

1

Signal & Procurement

The DNO identifies a future network constraint and posts a requirement on a marketplace platform (e.g., Piclo).

2

Pre-qualification

As an aggregator, you register on the platform and submit technical specifications for your aggregated assets.

3

Bidding Strategy

Analyse the tender and formulate competitive Availability (£/MW/h) and Utilisation (£/MWh) bids.

4

Automated Dispatch

Upon winning, receive dispatch signals and use your DERMS to automatically control the assets in your portfolio.

5

MVS & Settlement

Provide accurate metering data for Measurement, Verification, and Settlement (MVS) to ensure timely payment.

The Market Opportunity

DSOs are increasingly turning to market-based solutions to manage network constraints and defer costly infrastructure upgrades. This creates a significant revenue opportunity for aggregators who can deliver reliable, location-specific flexibility services.

Key System Benefits:

  • Saves Money: Defers billions in grid reinforcement, a saving ultimately passed on to consumers.
  • Increases Resilience: Creates a more robust and self-healing grid that can better handle faults.
  • Accelerates Net Zero: Allows faster integration of renewables, EVs, and heat pumps.

The Aggregator's Role

Success requires sophisticated technical and commercial capabilities to translate complex DSO requirements into actionable, automated dispatch instructions for your Distributed Energy Resource (DER) portfolio.

Core Aggregator Functions:

  • Portfolio Optimisation: Using a DERMS to co-optimise assets across local flexibility, ancillary services, and wholesale markets.
  • New Revenue Streams: Earning income for assets like batteries, CHP units, or flexible industrial processes.
  • Risk & Compliance: Managing performance obligations, baselining, and the MVS process.

The UK: A Global Leader

The UK is at the forefront of developing these markets, driven by ambitious net-zero targets and regulatory support from Ofgem. A key part of this is the evolution of DNOs into more active Distribution System Operators (DSOs), who actively manage energy flows using flexibility as a core tool. All of the UK's DNOs are now procuring flexibility, with the market projected to expand significantly.

Challenges & The Road Ahead

While the potential is enormous, challenges remain in standardising market rules and lowering barriers to entry for smaller participants. Looking forward, the market will become more sophisticated, with greater automation and deeper integration between local and national markets. Local flexibility is a fundamental building block of the smart, decarbonised grid of the future.
