Rolls-Royce begins construction of a large‑scale energy storage facility in Scotland
Rolls-Royce has begun work on its first large‑scale energy storage project in the United Kingdom. The investment is located in Falkirk, Scotland, and consists of a battery system with 43 MW of power and 86 MWh of storage capacity.
The project is being delivered under an EPC (engineering, procurement and construction) contract for Voltaria Helios Energy Storage. According to the schedule, the installation is expected to be connected to the grid in 2026 and reach full commercial operation in 2027.
Technology and partners
A key component of the project will be technology supplied by Contemporary Amperex Technology Limited, one of the global leaders in battery manufacturing. Rolls‑Royce will deploy its EnergyPack solution on site, enabling efficient energy management.
The system will store surplus energy during periods of high renewable generation—particularly from wind farms—and release it back into the grid during times of increased demand.
Importance for the energy transition
The new installation is expected to play a significant role in stabilizing the power system, especially as the share of renewables continues to grow. Energy storage systems of this type:
- reduce the need for curtailing wind generation,
- improve system balancing,
- decrease reliance on conventional power sources.
Additionally, Rolls‑Royce will provide a 15‑year full‑wrap service agreement covering comprehensive operation and maintenance of the facility.
Alignment with the UK’s strategy
The project supports the UK government’s ambitious Clean Power 2030 plan, which aims to reach 27 GW of energy storage capacity by the end of the decade. The expansion of this sector is considered essential for further integration of renewable energy and strengthening energy security.
The Falkirk investment is not only Rolls‑Royce’s debut in the large‑scale storage segment in the UK, but also a signal of the growing importance of battery technologies in Europe’s energy transition.
