The measure is a governmental subsidy scheme to engage private households in alternative energy generation. The support is aimed at small scale electricity generation (photovoltaic systems) and heat generation for residential buildings (solar, biomass, heat pumps). The Slovak Innovation and Energy Agency (SIEA) launched this project in 2015. Since its launch, the project has provided 13 500 coupons worth over EUR 30 million in total, resulting in over 18 000 installations of new renewable energy sources. The project’s total budget is EUR 45 million and the SIEA aimed to open two more rounds of grant applications after the first round, the second round started in 2019.
