Swansea Greener Grid Park Extension
About Swansea Greener Grid Park Extension
Welcome to our dedicated website for our proposals to extend our Swansea Greener Grid Park on land to the west of Rhydypandy Road, Morriston.
We have now submitted our planning application for Swansea Greener Grid Park Extension (April 2025). We are grateful to everyone who has engaged with us over the consultation period and have incorporated local feedback where possible.
Our current Greener Grid Park is under construction, building large electrical machines with flywheels (called synchronous compensators) which can replace the function of the spinning turbines of a traditional power station without emitting any carbon dioxide. Read more about our consented development (opens construction project website).
We are now proposing an extension to our Greener Grid Park which will use a different technology, Battery Energy Storage Systems, that also work to provide grid stability.
Why do we need Greener Grid Parks?
Greener Grid Parks are a collection of buildings and zero carbon technology which stabilise the grid, allowing more renewable energy to be transmitted through the network. They are not a wind or solar farm, the buildings resemble agricultural barns, storage units or shipping containers.
When renewable energy cannot meet the energy demand on the grid, the country has had to pause the renewable supply and switch on fossil fuel power which is costly for both consumers and the environment.
The proposals for expansion will use Battery Energy Storage Systems to provide grid stability. Batteries capture and store energy for future use. They increase the amount of renewable energy consumers can use by storing and releasing it when demand is high.
