Bidder for manufacturing site
A joint venture formed by Scottish and Southern Energy and Marsh Wind Technology could save 130 manufacturing jobs.
Wind Towers has been appointed by administrators as the preferred bidder for the Skykon plant in Campbeltown.
The company is expected to complete due diligence on the deal by the end of April.
Staff in the wind turbine tower factory, which is still working to fulfill an order for Siemens, were told of the developments today.
Andrew Davison, of administrator Ernst & Young, said: "There are a number of significant matters to resolve before any sale can be finalised, but we hope that today proves to be a milestone in our endeavours to find a buyer for the business."
The site was placed in administration last year when its Danish parent company filed for bankruptcy.
Skykon had bought the plant from previous owners Vestas in 2009.
Ian Marchant, chief executive of SSE, said: "The development of a sustainable supply chain is a key priority for renewable energy developers such as SSE, and I am pleased that we are working with Marsh Wind Technology to secure the future of the Machrihanish plant.
"With the right business plan and management, it should be a sustainable business in every sense. As the market for offshore wind turbines develops from 2013 onwards it should be possible to expand the operation to fully utilise the excellent facilities which are now available at the site.
"While some restructuring may be necessary at the plant to position it for growth we would envisage the substantial majority of the workforce being retained, while the joint venture partners would also be looking at potential redeployment opportunities."
William Marsh, founder of Marsh, said: "We are delighted to be able to expand our European supply chain footprint in partnership with SSE who has once again shown a real commitment to developing opportunities for Scotland in renewable energy.
"Both partners believe that this plant has an important role in building the supply chain base for the growing wind energy sector and that it will have a healthy future in the medium term as the demand for turbine components expands.
"It is our aim to build the Campbeltown operation into a stable and reliable partner to our customers with a singular focus on creating value in the supply chain."
