From a Brownfield Site to a Green Future

Parc Stormy has been redeveloped from a rundown brownfield site to a cluster of interconnected renewable energy technologies. The concept is modeled on Güssing, Austria, where a vibrant local economy has been created using renewable energy, natural resources and the re-use of waste materials. 

Site Timeline:

  • Shortly after its acquisition in 2007, it was decided to use the site to commercialize a low-carbon technology invented by researchers at Cardiff University that focuses on converting mineral wastes from industry into a new generation of low-carbon cement replacements.
  • In 2011, our first renewable energy investment was made in the form of a 750kW photo voltaic solar plant.
  • In 2015 a 1.5MW Vensys 77 wind turbine was commissioned.
  • Also in 2015, SOLCER House was built, an energy positive concept building of the future.
  • In 2016, a 3MW Anaerobic Digestion plant was built by Agrivert, later to be acquired by Severn Trent Green Power.
  • In 2018 a 4MW Tesla grid frequency balancing battery was installed on site.
  • In 2019, we were granted planning permission for a commercial vehicle EV charging depot at Parc Stormy.
  • In 2020, we commisioned our second wind turbine, a 3.6MW Vestas V117.
  • There are also several exciting future projects in the pipeline for Parc Stormy.

This cluster of green technologies offers a fantastic opportunity for education in sustainability and low-carbon energy production.  Cenin Group is attempting to demonstrate that considerable local economic benefit  and job creation can be achieved by SMEs simply by embracing collaborative approaches that are commonplace in Mainland Europe.

The History of Stormy Down

The site was originally built as an airfield to train both air and ground crews during the 1939-45 war. The grass airfield was located on the fields south of the site. More than 7,000 personnel were trained here.

During the 1950s the site was used as a location for an early warning radar station, of which there were many spread across the UK. The radar was later decommissioned. The auxiliary fire service were based here during the 1960s. In the late 1970s the site was used as a resettlement centre. From 1980-2010 a Sunday market and car boot sale was held at Parc Stormy, and from 1990-2005 a go cart track was in operation inside one of the large hangers.  Cenin acquired the site in 2007 in a poor condition littered with rubbish and derelict structures. After clearing up and refurbishment, the original hangers became the cement factory and drying sheds.
