The aim of the study was to assess the degree, structure and spatial diversity of absorption of Regional Operational Programme (ROP) resources of the Mazowieckie Voivodeship in the 2007-2013 perspective in the field of renewable energy. The study used data from the KSI SI MIK database of projects completed and settled in years 2007-2015, supplemented with data from official websites. In the years 2007-2015, there were 2,619 projects completed. Only 70 of them concerned energy (and the Holding Fund – JESSICA). The total value of the projects was PLN 412 200 982.40, which accounted for 3.7% of the value of all projects implemented under the ROP of the Mazowieckie Voivodeship. Among these 70 projects, 16 did not concern renewable energy, but thermo-modernization of buildings, whereas in the next 23 projects, thermo-modernization was the main part of the project. The largest number of projects was carried out in the ciechanowski and warszawski wschodni subregions (10 each), and the least in the płocki subregion (2) and in the Warsaw Metropolitan City – 5. Solar investment was definitely the most popular. However, the analysis of the results indicates insufficient support for the RES sector in the context of the EU requirements.
