Projects

Branxton - 650MW

The Branxton project is the largest of EHD's portfolio comprising of a 450MW and 170MW BESS shared connection totalling 650MW, with planning consent granted. The site is in close proximity to the current Eastern Link project being developed by Scottish Power. The Eastern Link is the site of the first of 4 new transmission cables from Scotland to England and Europe’s largest windfarm – SSE’s 4GW Berwick Bank windfarm. This will be the most used BESS location in GB with low cost grid power.  Tucked within a valley and hidden from view, the land has 49 acres with significant space to augment the BESS from 2h site to a 4h, 6h or even 8h site significantly increasing the opportunities within this development.

Rayleigh - 480MW

Rayleigh BESS is a 480MW site which has full planning consent on the land and approved cable route to connect directly into the Rayleigh Substation.

The Proposed Site comprises of approximately 4.80 hectares (ha) of agricultural land, primarily of which is subgrade 3b (moderate quality) agricultural land. The Site is located within the land at the Crouch Valley Showground, east of the A1245 in Rayleigh.

Due to the modest size of the Proposed Development, the lack of sensitive receptors in close proximity to the Site and the non-polluting nature of the Proposed Development, amongst other things, it was considered that the Proposed Development did not comprise of an Environmental Impact Assessment development. No objections were received from the public and the BESS was welcomed as an important infrastructure supporting the local area.

Gretna Green - 456MW

Dumfries and Galloway Council, like many others, declared a climate emergency and recognised the impact and responsibility to tackle climate change and fully commit to taking effective action to limit the impact on their region and its people. Gretna Green BESS will have a storage capacity of up to 456 MW of electricity, which helps to maintain grid stability and secure the power supply for the equivalent of over 100,000 average UK family homes while supporting the local transition to Net Zero through low carbon infrastructure.  The BESS at Gretna Green has received planning consent and will connect to the neighbouring substation.

Landscaping including generous biodiversity enhancements are proposed to screen the development, and minimise impact on its surroundings. The scheme will
also include other biodiversity and landscape enhancement
measures to provide significant biodiversity net gain.

Kincardine - 342MW

The Kincardine Battery Energy Storage System (BESS) site is on land to the north west of the Kincardine Generating Station and Substation, between the A876 and the Hawkhill Rd in Fife. Kincardine BESS will have a storage capacity of up to 342 MW of electricity and has received planning consent. Climate Fife projects will support an efficient ‘whole energy systems’ approach to moving, storing and transforming energy into different
forms. A whole energy systems approach looks at minimising
distribution, transmission and energy transformation losses by
making smart choices about the most appropriate energy sources
for a given time and location, and by joining networks and storage
options together so that they work holistically. Fife Council has set the same target of reaching net zero greenhouse gas emissions by 2045 at the latest, after declaring a Climate Emergency in 2019.

Cockenzie - 342MW 

Cockenzie BESS is currently being built with construction started in March 2026. Cockenzie BESS has two sites with shared connections, a 240MW and 102MW BESS.  Both will be operational and connected to grid by 2027. Locating the BESS project adjacent to the SPT Cockenzie Substation provides a viable and cost effective connection at this important node of the network. The site is located within land at the former Cockenzie Power Station under policy PROP EGT1 within the East Lothian Council Local Development Plan 2018. The proposed battery storage energy facility will provide a significant contribution to the energy storage targets in the timescales necessary to contribute to the UK’s progress in meeting its renewable energy targets. It will also provide a rapid-response electrical backup to the Scottish Power Transmission, providing a flexible system to balance energy supply and demand.

Ocker Hill -240MW

Ocker Hill is a 240MW BESS site being developed within an industrial, urban landscape creating a sustainable energy system for the local area. The Proposed Development is to deliver a BESS that will enable the storage of energy generated from renewable sources and its future distribution to both local and national networks, reducing reliance on non-renewable energy sources. The provision of renewable energy development will ensure local resilience to shift toward renewable energy and the reduction of non-renewable energy sources, in pursuit of the national target to achieve net zero carbon production; supporting the adaption of both local business and communities in SMBC area and the wider region. The proposed development will not result in any unacceptable or significant adverse impacts in terms of landscape, biodiversity, heritage, noise, highway, or visual amenity.

Mossmorran - 300MW

The Battery Energy Storage System (BESS) site is on land to the east of the Natural Gas Liquids Plant near Auchtertool, Fife, KY2 5UE. The BESS will have a storage capacity of up to 300 MW via a shared connection of a 200MW and a 100MW BESS, and has planning consent. The BESS infrastructure will connect to the neighbouring substation, the Site covers approximately 13.9 hectares (34.3 acres) of land, although this includes open areas and new landscape planting. The BESS will therefore not occupy the entirety of the land. Landscaping including generous biodiversity enhancements are proposed to screen the
development, and minimise impact on its surroundings. Mossmorran BESS will help to maintain grid stability and secure the power supply for thousands of UK family homes. Fife Council has set the same target of reaching net zero greenhouse gas emissions by 2045 at the latest, after declaring a Climate Emergency in 2019.
