Jobs saved by deal
Kingspan Renewables has bought troubled Proven Energy and saved 20 jobs.
Wind turbine manufacturer Proven went into administration last month when a fault was discovered in one of its main products.
The resulting financial problems led to 55 people being made redundant.
The sale - brokered by administrators from KPMG - means the company's facility in Stewarton, Ayrshire will continue to be used for manufacturing.
The sum Northern Irish firm Kingspan paid has not been revealed.
Noel Crowe, managing director of Kingspan environmental and renewables, confirmed plans to make three and six kilowatt turbines in Scotland and added: "A decision on whether or not to launch a 15KW turbine will be made at a later date, but any launch is unlikely to be before January 2013.
Nimmo, head of restructuring for KPMG in Scotland, said: "Following a competitive sales process, we are delighted to confirm the sale of the business and assets to Kingspan.
"We would like to thank Proven's remaining employees, customers and suppliers for their patience and support and would also like to thank the many parties who showed an interest during the sales process."
