The research by Raggnar, the renewable energy provider, analysed data from the government’s Renewable Heat Incentive (RHI) deployment data.
A total of 1,245 Scottish business started using RHI-backed renewable energy sources last year, adding 421 MW of clean energy to Britain’s energy capacity.
This means seven in every 1,000 Scottish businesses now use some form of RHI-backed renewable technology to generate their own energy.
Nigel Perkins, CEO of Raggnar, said: “2015 was a big year for the uptake of low-cost, locally-generated renewable energy by businesses in Scotland, with almost as many new installations and additional capacity as had been achieved in the three years that preceded it.
“We are seeing growing demand from community energy schemes and industrial users in particular, who can now use highly-efficient biomass technologies to become entirely self-sufficient on low-cost renewable energy, generate a rapid return on their investment from RHI payments and ensure a secure, long-term supply of clean power for even their most demanding industrial processes.”
RHI technologies include solar thermal, ground source heat, and - most commonly - biomass, which can be used to cleanly and efficiently heat and supply hot water to business premises, generate electricity and power industrial heating, drying and cooling systems.
