AN environmentally-friendly energy firm wants to build an experimental green energy park at a former Scottish nuclear plant, which could create more than 500 jobs.

Scotia Global Energy has put forward ambitious plans to transform the Chapelcross 90-hectare site near Annan, Dumfries and Galloway, claiming it is “ideally positioned” for a hybrid power station intended to radically reduce carbon dioxide emissions.

The development would also include a 10,000 sq ft administration building – public exhibition space on the ground floor and flexible office accommodation on the first floor, laboratory space for energy research and a zone for four community energy projects.

The company has put its proposals to the Scottish Government and Dumfries and Galloway Council, as well as Scottish Enterprise and the Nuclear Decommissioning Authority (NDA).

A report on the plans stated that the existing electricity grid connection, its proximity to the gas grid and the water abstraction facilities that are on site are an “ideal mix”, the report added.

It claims a development company set up to manage the early stages of the project could initially support five jobs.

However, the report said: “As the site matures, the manufacturing supply chain operations could support several hundreds of jobs conceivably exceeding the site’s historical peak of 500 jobs.”

Dumfries and Galloway Council said it was working with Scottish Enterprise and the NDA on the regeneration of the Chapelcross site.

A council spokesman said: “The council, along with Scottish Enterprise and the NDA, are working together to bring forward proposals for the regeneration of the Chapelcross site. The partners recognise that the Chapelcross site represents a major opportunity to attract inward investment and create new jobs which will have a positive impact on the regional economy. The vision for the site is to develop a sustainable, mixed use approach providing opportunities for large and small scale businesses across a range of sectors. It is highly likely that the energy sector will play a prominent role within that mix, with opportunities for research and development, generation, and storage.”

An NDA spokesman told the BBC they have had one “exploratory meeting” with a representative of Scotia Global Energy. He added: “The idea for an ‘integrated energy centre’ seems to fit in general terms with the emerging development framework for the Chapelcross site but we would need considerably more details before giving serious consideration to this proposal.”

The Chapelcross Works was the sister plant to Calder Hall in Cumbria and was officially opened in May 1959 by the Lord Lieutenant of Dumfriesshire, Sir John Crabbe.

The main purpose of the site was to produce plutonium for the UK’s nuclear weapons programme and electricity was always viewed as to be a by-product. Ownership of all of the site was transferred to the NDA, when it was set up as the new regulatory body by The Energy Act of 2004.

The plant stopped operating in June 2004 and decommissioning work began the following year, which included demolishing the cooling towers, and by 2013 all four reactors were removed.
