Aarhus-based energy trading company Danske Commodities has been chosen as one of several optimisation partners for the Hunterston battery energy storage system in North Ayrshire, Scotland. The project has a capacity of 400 MW and 800 MWh, making it one of the largest battery schemes in the UK, and is due to begin commercial operation in the third quarter of 2028.
Hunterston is being developed by Revera Energy, which is backed by the global investment firm Carlyle. Under a long-term agreement, Danske Commodities will provide trading and optimisation services for the battery using what is described as a revenue floor model. Under that model, the battery’s owner is assured a minimum level of income from the trading arrangement. The deal builds on an existing relationship between the two companies. Earlier in 2026, Revera picked Danske Commodities as optimisation partner for Windyhill, a 400 MWh battery project.
The work relies on software rather than traders at screens. Danske Commodities runs a fully automated algorithmic setup intended to get the most value from batteries across wholesale power markets and the markets that pay for supporting grid stability. Batteries charge when wind and solar output is high and release power to the grid when it is needed, so their earnings depend on how their capacity is managed hour by hour. That makes the quality of the trading system central to how much a project like Hunterston can earn.
Chief executive Jakob Sørensen said: “The UK is a core market for us.” He linked the deal to the company’s ambition to be a leading player in energy trading and asset management. Danske Commodities already manages a contract portfolio of 17 GW of renewable and flexible energy across Europe, and the Hunterston agreement adds another large storage asset to the capacity it handles from Aarhus.
The project still has some way to go before it starts earning. With commercial operation planned for the third quarter of 2028, the next stage is construction by Revera, while Danske Commodities prepares its trading systems for a battery that will rank among the biggest in Britain. For the Danish trader, the agreement deepens its position in the UK storage market at a time when batteries are taking on a larger role in balancing grids built around wind and solar power.
