Rolls-Royce and Voltaria to Deliver 43 MW Battery Storage Project in Scotland
Rolls-Royce partners with Voltaria to deploy large-scale battery system supporting the UK’s clean energy transition.

Rolls-Royce has begun construction of a 43 MW battery energy storage facility in Falkirk, Scotland, marking its first large-scale battery storage project in the UK.
Project overview: Large-scale storage for grid support
The project, developed for Voltaria Helios Energy Storage, will feature an installed capacity of 86 MWh and a power output of 43 MW. The system will be based on Rolls-Royce’s mtu EnergyPack solution and is designed to support grid stability and renewable energy integration.
Once operational, the facility will be capable of supplying electricity equivalent to the demand of approximately 10,000 homes or a large industrial site.
Function: Enabling renewable energy integration
The battery system will store excess electricity generated during periods of high renewable output and feed it back into the grid during peak demand.
This capability is critical for:
- Reducing renewable energy curtailment
- Balancing supply and demand
- Supporting a more flexible and resilient energy system
Timeline and execution
The project is being delivered under a full Engineering, Procurement, and Construction (EPC) contract, with Rolls-Royce providing a turnkey solution along with a 15-year long-term service agreement.

- Grid connection expected: 2026
- Full operation: 2027
Strategic context: Supporting UK energy targets
The project aligns with the UK’s Clean Power 2030 Action Plan, which targets 27 GW of battery storage capacity by 2030.

Battery energy storage systems (BESS) play a central role in enabling carbon-free electricity by:
- Maximising renewable generation
- Reducing reliance on fossil fuels
- Enhancing grid flexibility
Partnership and technology
The collaboration brings together Rolls-Royce’s expertise in turnkey energy systems and Voltaria’s investment and development capabilities. The project will also utilise battery technology from CATL.
Rolls-Royce has already deployed more than 200 battery storage systems worldwide, reinforcing its experience in delivering scalable energy storage solutions.
Conclusion: Strengthening energy transition infrastructure
The Falkirk battery storage project represents a key step in expanding large-scale energy storage infrastructure in the UK. By combining advanced storage technology with long-term service support, Rolls-Royce and Voltaria are contributing to a more stable, efficient, and low-carbon energy system.
