Blog: Behind the Meter Flexibility: Turning Opportunity into Revenue
In our previous blog, we looked at the growing role of Behind the Meter (BtM) flexibility in Great Britain’s energy future. If you missed it, you can catch up here:
Exploring Behind-the-Meter Flexibility
We outlined how BtM assets are becoming an essential part of a more decentralised, flexible energy system. Now we’re taking a closer look at the next big question: how do you make it pay?
With up to 70GW of BtM flexibility expected by 2050, monetisation will be key to driving adoption, both for end users and the providers who help them unlock value.
New Routes Into the Market
Recent regulatory updates are reshaping the landscape for BtM participation and making it easier for assets to access commercial opportunities.
Two key changes to the Balancing and Settlement Code have been especially important:
P415 allows Virtual Lead Parties (VLPs) to participate directly in the wholesale market without needing a licensed supplier. This opens up more flexibility for more players, especially independent aggregators.
P444 introduces a fair compensation mechanism for VLP actions in the Balancing Mechanism. This levels the playing field and gives all participants greater confidence in BtM involvement.
These changes not only create more room for innovation but also give suppliers greater incentive to bring flexible offerings to market.
Where the Value Is
Revenue opportunities for BtM assets are more varied and more accessible than ever before. The most common include:
1. Capacity Market
Assets are paid for being available during system stress events. This provides a reliable long-term income stream, with the most recent T-1 clearing price at £20 per kilowatt.
2. Local Flexibility Services
Distribution System Operators (DSOs) procure local services to manage network constraints. These include load shifting, scheduled use and demand response. BtM assets that can support these needs are increasingly valuable, though availability still depends on the region.
3. Day-Ahead and Intraday Trading
Aggregated BtM assets can take advantage of wholesale price movements by adjusting operations in real time. They can reduce consumption when prices are high or export stored energy when it makes financial sense.
4. Balancing Mechanism
The Balancing Mechanism helps the system stay in balance. With clearer access routes and better protections in place, BtM participation is becoming more viable and attractive.
5. Ancillary Services
From fast frequency response to reserve services, these critical system stabilisers are opening up to distributed energy assets, especially where they can be aggregated.
6. Network Energy Cost Optimisation
Large commercial and industrial users can generate savings by avoiding peak periods and reducing their exposure to charges such as DUoS or Triads. For many, this is a key benefit of BtM flexibility, turning cost avoidance into value generation.
Aggregation and Forecasting: The Keys to Scale
The majority of BtM revenue streams require participation thresholds that small individual assets cannot meet alone. This is where aggregation becomes essential.
By pooling smaller BtM assets, aggregators can:
- Meet market access requirements
- Optimise across a larger, more flexible portfolio
- Increase returns for all participants
But this only works with reliable forecasting. Aggregators must be able to predict:
- When and how assets will be available
- On-site generation from solar, batteries or CHP
- Usage behaviour and response capability
- External conditions such as weather and pricing trends
The better the forecast, the more reliable the flexibility and the more value that can be captured.
As participation grows, flexibility optimisers may become just as important to end users as energy suppliers. Choosing the right one could be key to maximising returns and system impact.
Looking Ahead
The monetisation of BtM flexibility is already happening, but to scale it further, we need continued alignment across regulation, systems and incentives.
That includes:
- Better coordination between DSOs
- Standardisation of local services
- Clearer, more transparent market signals
This is a real opportunity for consumers to become active participants in the energy transition, and for providers to build scalable, data-driven solutions that reward flexibility fairly.
BtM flexibility is no longer a future concept. It is a growing part of how we power the grid, balance demand, and move toward net zero.
