REFINE is a H2020 EU-funded project that aims to improve the supply of sufficient and attractive financing sources for energy efficiency investments and mainstream refinancing instruments for future energy efficiency projects across Europe. Within this scope, it seeks to create new business opportunities for financial institutions by establishing well-structured refinancing schemes for Energy Efficiency Services (EES) practices. REFINE partners have identified a large market potential for sustainable finance in the energy efficiency field that is just waiting for a smart way to be instrumentalized. Several case studies and a market assessment carried out earlier within the project have shown the advantages brought by refinancing schemes. Over time, REFINE will cooperate with key stakeholders including financial institutions, EES providers, market facilitators and guarantee funds, using their knowledge and expertise to support anyone who is interested in growing within this business area.
