The aim of the research was to determine the forms of support provided to energy clusters in Poland. The author sought to answer the following questions: What activities do energy clusters receive support for? Does the support come from foreign (EU) or domestic funds? How do energy clusters fit in the current cluster policy in Poland? The study area was the Lower Silesia Voivodeship – one of 16 administrative regions of Poland. The author selected this region, because it has the largest number of energy clusters in Poland. The following methods were used to achieve the goal of the research: (1) a review of literature and industry reports; (2) a CAWI survey of clusters; and (3) interviews with cluster coordinators. Public support received by the surveyed clusters concerned either the commencement or the continuation of cluster activity. In the initial phase of the clusters activity, the support received concerned documentation work, drafting plans for the expansion of the power grid, and purchasing an energy monitoring and management system. At later stages of cluster development, the implemented projects mainly concerned the construction of ground-based PV farms and photovoltaic installations on the roofs of public utility buildings. Less frequently implemented projects included the thermal modernisation of public buildings, hybrid investments (PV and wind turbine), and energy storage facilities. Apart from the above, educational projects were implemented. The support funds came mainly from the EU funds (Operational Programmes and the Interreg programme). In turn, support from national funds came from the Voivodeship Fund for Environmental Protection and Water Management, from local government funds, or from the Polish Deal, i.e. the government’s programme of strategic investments.
