Zero injuries onsite in over 20,000 hours worked

6th February 2018

Our latest 20MW embedded gas plant, at Cattedown Business Park in Plymouth, was completed ahead of time, with zero injuries.

Working closely with Green Frog Connect, the project was completed to tight timescales after winning a capacity market obligation in National Grid’s Early Auction on 3rd February 2017, for delivery by October 2017. Located on a challenging site, the plant occupies a site previously utilised as a tip for building material and a quarry. Despite the tight timescales, the site was generating and available for export from mid-September, and is now available to respond to Capacity Market Warnings issued by National Grid.
