We are proposing to build a 500 MW Long Duration Electricity Storage (LDES) project on consented industrial land at the Hagshaw Energy Cluster, south-west of Junction 11 of the M74 motorway in South Lanarkshire.

The Hagshaw Cluster has long been at the heart of Scotland’s renewable energy ambitions. Previously granted consent for a multi-use renewable energy and industrial hub, the strategic importance of this site remains unchanged. Now, as it transitions to become Hagshaw LDES, it is evolving to meet Scotland’s growing need for electricity storage to achieve our decarbonisation requirements.

Hagshaw LDES ensures that this strategically significant renewable energy hub continues to be a cornerstone of Scotland’s net zero future while delivering direct benefits to the local community.

Public Consultation

We will be holding two drop-in public consultation events into the proposal at which you can view our plans, learn more about our proposal, and talk to the project team. You are welcome to join us at any time that is convenient.

We are holding our consultation events on:

Thursday 13th March 2025
2pm – 7pm
at the St Bride’s Centre, Braehead, Douglas ML11 0PT

Thursday 3rd April 2025
2pm – 7pm
at the Coalburn Miner’s Welfare, 42 Coalburn Road,
Coalburn, ML11 0LH

A LDES site is a facility designed to store and release electricity over long periods, anywhere from several hours to days or even weeks. These sites are essential to the green energy transition as they help create a more stable and reliable electricity grid by storing surplus renewable energy and delivering it back to the grid when it is needed most.

At this site, we’re using flow batteries, a type of LDES technology known for its safety, durability, and efficiency. Unlike lithium-ion batteries, flow batteries use a water based, non-flammable electrolyte, significantly reducing fire risk. They also operate quietly and produce no emissions, making them safer and more environmentally friendly.

LDES technologies like these provide a different service to the electricity grid, with much greater capacity and longer discharge durations than traditional battery storage schemes, which typically store energy for only a few hours. With minimal degradation over time, flow batteries are built to last, ensuring a reliable and sustainable energy solution for the future.

We are currently proposing a community benefit contribution of £50,000 per year (index-linked) as part of our Hagshaw LDES proposals. We are keen to hear your views on how the community benefit fund could be used.

People wishing to make comments to the Applicant relating to the proposal may do so via info@3renergy.co.uk. We will be accepting pre-application submission comments until Friday 11 April 2025. Comments made to the Applicant are not representations to the Scottish Ministers. If the Applicant submits a planning application there will be an opportunity for consultees to make representations on the application to the Scottish Ministers at that time.
