Project Overview
Medlock Battery Energy Storage System (BESS) is a 30MW project that will deliver vital flexibility to the UK energy system, helping to decarbonise the grid and support local energy resilience. The project is currently in the planning appeal process following an initial refusal at committee, despite a recommendation for approval by planning officers.
Medlock BESS will provide fast-response flexibility to the grid, storing renewable electricity and helping balance local and national supply and demand. Once operational, it will contribute to a more resilient and decarbonised electricity system.
The site, located in an area sometimes referred to as “grey belt” due to its position and limited contribution to Green Belt purposes, is well screened by existing vegetation and topography. The land itself is unsuitable for most other uses due to its terrain.
PRE APPLICATION
An accelerated connection offer has been secured meaning this project can provide benefits from 2026.
Medlock BESS will deliver a 10% biodiversity net gain, providing enhanced habitats and supporting local wildlife.
The project received a recommendation for approval from planning officers, but was refused at committee on the grounds of inappropriate development in the Green Belt. We have submitted an appeal to the Planning Inspectorate, supported by a comprehensive case which demonstrates the limited impact of the scheme on the purposes of the Green Belt and highlights its significant public benefits.
We continue to engage openly with local community groups. In response to local feedback, we have committed to helping tackle flytipping in the area through the provision of new fencing and CCTV around the site perimeter.
- Capacity: 30MW
- Storage: 60MWh
- Homes Powered: 60,000
- Energisation Date: Mid-2026
Timeline and next steps
An accelerated grid connection offer has been secured, enabling the project to start delivering local and national energy system benefits as early as 2026, subject to a successful appeal outcome.
We remain committed to working with local stakeholders to ensure that Medlock BESS brings lasting positive outcomes to the area.
