Executive Summary
Commercial Battery storage is evolving rapidly. While systems have traditionally been deployed only to increase solar self-consumption, the market is increasingly shifting towards intelligent optimisation and financial value stacking.
To support this transition, AlphaESS and Capture Energy have announced a strategic integration that combines AlphaESS’s product solution with Capture’s advanced optimisation platform.
For customers, this creates an opportunity to extract greater value from battery investments through tariff optimisation, increased solar self-consumption, and participation in grid services. For installers and renewable businesses, it provides a more compelling and future-proof investment proposition to present to customers.
As a specialist in Commercial Battery Storage, Immersa has chosen to work alongside Capture Energy because of their proven capabilities, strong technical expertise and a growing track record of delivering real-world projects across the UK.
About Capture Energy
Capture Energy is a UK-based energy technology company specialising in battery optimisation, flexibility market participation and energy supply.
The business has developed a sophisticated, machine-learning platform that enables batteries to respond dynamically to changing energy market conditions. Their software continuously analyses factors such as tariffs, site demand profiles, solar generation forecasts and market opportunities to determine the most valuable operating strategy.
Capture is qualified to participate in several UK flexibility and wholesale energy markets, allowing assets to generate value from multiple revenue streams while continuing to support customers’ operational requirements.
Making Optimisation Easier with AlphaESS x Capture
The AlphaESS x Capture integration has been designed to make this process easier.
Capture works through AlphaESS’s API, meaning there is no need for additional costly hardware to be installed on-site. This makes the proposition easier to explain, more practical, and gives the ability to onboard AlphaESS systems in minutes.
That simplicity matters.
Commercial battery projects already involve technical design, grid considerations, site-specific sizing and financial modelling. By making the optimisation layer easier to integrate, installers can present a more complete solution without adding unnecessary complexity for the customer.
For businesses, it also helps answer one of the most important questions after installation: how do we make sure the battery keeps delivering value?
With Capture’s optimisation layer, the system can continue responding to changing site conditions, tariffs, solar forecasts and market opportunities. That helps customers move beyond a passive storage model and towards a more active energy strategy.
Real-World Example: AlphaESS TB125 with Capture
Capture has already demonstrated this approach through a live commercial battery project using an AlphaESS TB125.
The customer faced a common challenge. Most electricity consumption occurred during working hours when energy prices were highest, while cheaper overnight electricity could not be utilised effectively because of limited night-time demand.
Using Capture’s optimisation platform, the battery charges during lower-cost periods and discharges during higher-cost periods, reducing expensive grid imports without affecting normal business operations.
With Capture and Immersa, the project boasted the following:
- Installation completed within a single day and commissioned within one week of the TB125 arriving in the UK.
- Delivers estimated annual net benefits of approximately £10,000–£12,000 through tariff optimisation and flex market participation.
- Results in an expected payback of less than four years.

The project demonstrates how commercial battery storage can already deliver meaningful financial returns when paired with intelligent optimisation.
What This Means for Installers and Commercial Customers
The UK commercial battery market is entering a new phase.
As battery costs continue to fall and flexibility markets mature, successful projects will increasingly rely on combining multiple value streams rather than focusing solely on solar self-consumption or peak demand reduction.
The AlphaESS and Capture partnership provides a framework for achieving this.
For commercial customers, it creates an opportunity to maximise returns on battery investments while supporting wider sustainability and energy resilience objectives.
For installers and renewable energy partners, it offers a stronger proposition that combines industry-leading battery technology with advanced optimisation capabilities and expert commercial support from Immersa.
Looking Ahead
At Immersa, we believe commercial battery storage should be measured not only by its capacity, but by the value it delivers over its lifetime.
Our partnership with Capture Energy reflects that philosophy.
By combining AlphaESS hardware, Capture’s optimisation expertise and Immersa’s commercial battery storage experience, we can help customers and partners unlock greater performance, stronger returns and a smarter approach to energy management.
