Varco Energy announced on the 14th April 2025 that it has started full commercial operations at its new Native River battery energy storage system (BESS).
The Native River Battery Energy Storage System (BESS) is a significant advancement in the UK’s renewable energy infrastructure, strategically located south of Liverpool. This project is a collaborative effort between Varco Energy, a UK-based battery storage asset owner and operator, and GE Vernova, the energy division of General Electric.
Project Overview
- Capacity: 57 megawatts (MW) power output and 138 megawatt-hours (MWh) energy storage capacity.
- Location: South of Liverpool, within a historically congested part of the UK electricity grid.
- Construction Timeline: Began in the third quarter of 2023, with grid connection anticipated in early 2024.
- Developer: Varco Energy, funded by Adaptogen Capital.
- Technology Provider: GE Vernova, supplying the complete BESS, including FLEXInverter, FLEXReservoir, and FlexIQ solutions.
Energy Supply Potential
The Native River BESS has the capacity to power approximately 37,000 UK homes with clean, renewable energy.
Technical Specifications
GE Vernova is providing modular units comprising:
- FLEXInverter: Converts stored DC energy to AC for grid compatibility.
- FLEXReservoir: Manages energy storage and discharge.
- FlexIQ: Offers intelligent control and monitoring for optimal performance.
These components are designed to be scalable, meeting the project’s capacity requirements and providing balancing and capacity services to the National Grid.
Construction and Infrastructure
Ethical Power Connections has been contracted to provide the Balance of Plant (BoP) work and act as the Independent Connections Provider (ICP). Their responsibilities include the electrical, mechanical, and civil infrastructure necessary for connecting the BESS to the National Grid’s transmission network.
Financial Aspects
Varco Energy secured £58 million in debt financing from NatWest to fund the construction of the Native River project and a similar BESS project named Sizing John. The financing package includes a £50 million capital expenditure facility and an £8 million VAT facility.
Significance
The Native River BESS plays a crucial role in supporting the UK’s transition to a net-zero future. By providing grid stability and facilitating the integration of renewable energy sources, it addresses the challenges of intermittent renewable generation and contributes to a more resilient energy system.
Richard Whitmore, director of Varco Energy, called the start of commercial operations at Native River a milestone that “represents a significant step forward in Varco’s expanding portfolio of BESS assets”. Whitmore also thanked Varco’s team for the delivery of the project, praising their “unwavering dedication, expertise and commitment”.
