Social Investment Scotland (SIS) has a role in funding the UK’s largest community-owned commercial-scale wind farm, Beinn Ghrideag in the Western Isles. Led by former MP Calum MacDonald, the 9MW project breaks new ground in community-owned renewables projects previously been kept small scale as community groups struggled to secure sufficient finance. The size and scale of the wind farm are not of greatest significance. The potential social and economic benefits that such innovative community-owned projects can bring are. Studies have shown that the local economic impact of renewable energy projects is much greater from community-owned schemes than from private developer-led schemes paying into a community-benefit fund. In the case of Beinn Ghrideag, it is expected that, over the course of a 25-year lifespan, it will return £20 million to community projects across the Western Isles.
