Powin and Pulse Clean Energy partner on Scottish battery project

Global energy storage platform provider Powin and Pulse Clean Energy, an investor, developer and operator of flexibility and stability assets in the UK, will deploy a 50MW/110MWh Battery Energy Storage System (BESS) on the Scottish project Overhill, located in Aberdeen.

Powin, a US-based energy storage platform provider, will provide its Stack750 energy storage system with integrated StackOS software, while Pulse will oversee asset delivery and manage operations across the project lifecycle.

The Overhill project is scheduled to enter full commercial operations by mid-2025.

The project will provide services to maintain balance within the power grid, enabling more renewables to be connected securely to the UK energy system.

Once operational, the Scottish battery project will be capable of storing surplus renewable generation during periods of high production for release back into the grid during periods of lower production or high system demand.

“After detailed evaluation, Pulse determined that Powin’s capabilities and technology stack placed them as one of the leading players in the BESS market. This agreement with Powin underscores our shared commitment to innovation and the pursuit of a cleaner, more affordable and secure energy system,” said Aazzum Yassir, director of Technology & Operations at Pulse.

BESS deployments

The agreement, which according to Energy-Storage News is a first for Powin in the UK, comes after numerous other battery energy storage deployments by Powin and in the UK.

Two weeks prior, Powin announced a project alongside Galp, a Portuguese-integrated energy company.

The two companies will instal a utility-scale BESS at one of Galp’s solar power plants near Alcoutim, a small village in the country’s sunny southern region of the Algarve, where Galp operates several projects with a combined capacity of 144MW.

The batteries will allow Galp to store the solar energy produced in periods of high generation, and to deploy it during periods of high demand, alleviating stress from the power grid.

“This particular project with Galp is bigger than its MW impact – it is the beginning of a new partnership and is Powin’s first project in Europe following the opening of our Madrid office. Europe is expected to deploy over 90GWh of utility-scale battery energy storage projects by 2030 and we are well positioned to support this demand along with the wider EMEA region’s rapid energy storage growth,” said Powin CEO, Jeff Waters.

Additionally, in the UK, several announcements have been made of BESS deployments to support the power grid.

Earlier this week, British energy developer Balance Power secured planning approval for a 40MW battery storage project in Cheshire, which will export stored renewable power to the grid when demand is high.

The project, located in Cheadle, will balance intermittency on the UK grid and provide stability for around 90,000 homes.

Announced the same day as Balance Power, news was released of financial close for TagEnergy’s 49.9MW/99.8MWh Pitkevy facility in Fife, Scotland, the company’s sixth battery energy storage system (BESS) project in the UK.

The project marks TagEnergy’s first split-contract project, with Tesla providing a Megapack 2XL battery system and contractor RJ McLeod executing site works and installation. Flexitricity will be acting as route to market and battery optimiser and RES has been appointed as asset manager.

The British government has established targets to ensure the power sector achieves net zero by 2035.

By 2030, the UK will require nearly 40GWh of BESS to help integrate renewable energy, enhancing the stability and security of the UK electricity system. BESS is a key enabler to help the government reach this ambitious goal.
