The offer aims to raise £550,000 with a minimum investment of £100 and a protected average annual return of 6.5 per cent over 20 years.
This follows a successful share offering this summer which raised over £1 million for the two small community-owned projects. The offering encourages local participation, giving priority to people living within 20 miles of the projects.
Small Wind Co-op director Jon Halle said: “Over 300 people joined us to help raise over £1 million this summer which means the groundwork is now getting underway in Inverclyde and the turbine has been ordered for Ceredigion.
“We’re building on that momentum with our second offer and we really want to encourage those living near the turbines to join our supporters from across Scotland and the UK.”
The projects are both supported by the government-guaranteed Feed-in-Tariff and has attracted support from politicians across Scotland and Wales.
Scottish National Party MSP Stuart McMillan said: “It’s great news that work is about to start on the Kellybank turbines, supporting initiatives that improve employment prospects and grow a further sense of community in Inverclyde.
“The Scottish government will ensure that by 2020 at least half of newly consented renewable energy projects will have an element of shared ownership like this one. And we will argue for Scottish control of our share of feed-in tariffs to help promote community ownership schemes.”
