3R Energy is working on a new generation of renewable energy projects, which have the potential to further contribute to national renewable energy and climate change targets, as well as the local and regional economy.

The Hagshaw Hill III development is expected to comprise around eight wind turbines, approximately 30 megawatts (MW) of solar photovoltaic energy generation, and approximately 50 MW of Long Duration Electricity Storage (LDES).

3R Energy is committed to engaging positively with communities in the local area to ensure that the final project design maximises benefits to be delivered locally. The design of the project is ongoing while data in relation to the site conditions continues to be collected. The final proposals will be informed by the results of environmental and technical surveys and the feedback from the Scoping process and community consultation exercises.

Hagshaw Hill III would neighbour the existing Hagshaw Hill and Douglas West wind farms and consist of up to eight wind turbines with a maximum blade tip height of 200 metres. The same height as those currently being constructed within the Hagshaw Cluster.

The proposals also include for approximately 30 MW of solar panels, to complement the wind generation and ensure electricity production even when the wind isn’t blowing and forms a core part of the UK Governments’ Net Zero 2030 target.

Using the same technology as proposed for our Hagshaw LDES proposal, Hagshaw Hill III will include a circa 50 MW LDES facility, designed to store and release electricity over long periods. These sites are essential to the green energy transition as they help create a more stable and reliable electricity grid by storing the surplus renewable energy produced by the wind turbines and solar panels and delivering it back to the grid when it is needed most.

At Hagshaw Hill III, we are proposing to use a network of 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. The LDES at Hagshaw Hill III would be capable of discharging around 50 MW of electricity over a period of up to 12 hours, which is enough electricity to power approximately 130,000 homes for a continuous period of up to 12 hours.

Consultation

We have now submitted a Scoping Request to the Scottish Government Energy Consents Unit in July 2025.

Persons wishing to make comments to the applicant relating to the proposal may do so via info@3renergy.co.uk. Comments made to the Applicant are not representations to the Scottish Ministers. Once the Applicant submits a planning application there will be an opportunity for consultees to make representations on the application to the Scottish Ministers.

Further details on our proposals, including a programme of community consultation, will be made available in due course.

Community Benefits

Based on the current layout, the proposed development would generate a community benefit contribution of around £288,000 per year (index-linked) or £11.52 million over its lifetime of 40 years.

3R Energy are keen to hear the communities’ ideas on how the revenue from the project could be used to enhance the local area and deliver projects that provide lasting benefit.
