The research paper is focused on how to choose the most suitable renewable energy solution using multi-criteria analysis for a district heating system. Making choices is based on indicators-economic, environmental and social. In this case, the study used five indicators: Resources costs, totals investments, reduction of greenhouse gas emissions, specific weight of renewable energy resources and impact on utilized land. Three situations have been compared-current situation: Gas boiler, planned: Solar collectors 21 595 m2 + accumulation tank 8000 m3 and alternatives: Solar PV panels 5504 m2-heat pump COP 3 are used in the estimation. The multi-criteria decision-making analysis shows that solar collectors 21 595 m2 + accumulation tank 8000 m3 are considered as the best alternative. The methodology is based on choosing a solution for a district heating company in Latvia.
