A project financed under the EU program Horizon 2020, Energy Performance Contracting Plus (EPC+) focuses on reducing transaction costs relating to energy services with the aim of promoting their use by small and medium enterprises (SME). This objective can be achieved by standardizing technical solutions and contractual matters relating to energy services. The main outcome of the EPC+ project was the establishment of functioning structured partnerships between companies from the SME segment referred to as clusters (SPIN). SPIN clusters have executed two successful pilot projects in the Czech Republic. Moreover, the project offered market participants seminars and information on technical, financial, and contractual aspects of EPC.
