Energy solutions company Rolls-Royce has started construction of a 43 MW battery energy storage system (BESS) in Falkirk, Scotland, under an engineering, procurement and construction (EPC) contract awarded by owner-operator Voltaria Helios Energy Storage.
The facility will have a storage capacity of 86MWh and is expected to be connected to the grid in 2026, with commercial operations planned for 2027. This is Rolls-Royce’s first large-scale BESS project in the UK. In addition, the company will enter into a 15-year maintenance agreement for the system.
The project will use battery technology supplied by Chinese battery OEM Contemporary Amperex Technology Limited (CATL).
“Rolls-Royce was selected because we were impressed with their commercial and technical offering, as well as their technical advice and involvement in the lead-up to the decision, and their 15-year full-wrap long-term service agreement. Rolls-Royce and the CATL battery solution are market leaders and both stand for quality, so our expectations for the delivery and execution of this project are high,” said Nigel Jefferson, CEO of Voltaria.
Rolls-Royce will deploy its mtu EnergyPack solution at the site, allowing the system to store electricity during periods of high renewable generation and send it to the grid at times of peak demand.
According to the company, the system will store electricity during periods of high renewable generation and send it to the grid during peak demand. The battery storage will also support additional renewable capacity by reducing the need to curtail wind generation.
In addition, the mtu EnergyPack aims to: The UK Government’s Clean Power 2030 Action Planwhich aims to have a battery storage capacity of 27 GW by 2030. Increased deployment of battery storage is expected to help balance supply and demand, maximize renewable energy production and reduce dependence on fossil fuel-based generation, the company said.
