UK battery storage project developer Clearstone Energy has unveiled the first project in a 2.2GW pipeline, the largest by an independent developer, it claimed.

The 400MW/800MWh Junction 27 project in the South West of England is the first site in a UK BESS project pipeline of 8 large-scale projects with a combined capacity of 2.2GW for which Clearstone Energy is aiming to seek planning consent over the next 12 months.

Three of the projects are 400MW while the remainder are planned to be 300MW/200MW.

The Junction 27 Energy Hub is on low-grade agricultural land near existing transport infrastructure on the M5 corridor in Devon. The project will “help balance electricity supply and demand across Devon and Cornwall and reduce reliance on gas-fired power stations,” according to Clearstone.

Clearstone says the project has received “broad support from the local community during a public consultation this summer before planning submission.” The project includes a major biodiversity component and “will deliver a comprehensive community value offering” including financial support for low income households to implement energy efficiency savings.

The pipeline projects have energisation dates from 2027-2032, which Clearstone says ”represents the largest near-term battery energy storage pipeline in the UK originated by an independent developer.”
