Cultybraggan camp has been awarded more than £35,000 to extend a biomass heating system.
The former Second World War prisoner of war (POW) camp is being regenerated by the Comrie Development Trust.
It plans to connect 10 listed Nissen huts to the heating system as part of their refurbishment into self-catering accommodation
Cultybraggan is one of the best preserved and last remaining high-security POW camps in the UK and is recognised by Historic Scotland as being of international significance.
Over the next five years, the refurbished huts are expected to attract more than 20,600 visitors, creating an income of more than £1.4 million for the local area.
The cash was a share of SSE’s £250,000 Perthshire Sustainable Development Fund.
Bob Hughes, treasurer of the Comrie Development Trust, said: “The grant brings closer the prospect of securing the future of an important group of listed buildings within Cultybraggan Camp: a community owned historic environment of international significance.
“Taken together with support offered by Historic Scotland, a major proportion of the capital funding has now been identified.
“The Sustainable Development Fund will allow these buildings planned for self-catering accommodation to be connected to the camp’s district heating system, and solar PV array, and so maximise the use of green energy.”
Other successful bids to the fund included a £50,000 award to the Highland Perthshire Communities Partnership to employ three local technical trainees to progress a high-speed rural broadband initiative and £40,000 to the Ericht Trust in Blairgowrie to purchase the disused Hill School for redevelopment as a community cinema and venue.
SSE has three operational wind farms in Perthshire Drumderg, near Alyth, constructed in 2008 and the neighbouring Griffin and Calliachar wind farms, near Aberfeldy, constructed in 2010 and 2012.
