In Europe, the non-profit sector employs 28 million full-time workers engaged in education, research, housing, counselling, workforce training and other social activities. The sector remains underserved by the financial industry, making it challenging to obtain funding to undertake clean energy investments. SER brings together 8 organizations from 4 EU countries to maximise social impact by boosting clean energy investments in the nonprofit sector. SER intends to consolidate and implement an innovative hub that will offer full technical and financial assistance to TSOs in deploying clean energy projects, including a de-risking financing instrument (guarantee instrument) to support the projects. The SER HUB will advise TSO’s to be able to design, structure and coordinate the high impact execution of projects. It will be configured as one-stop-shop (establishing an ecosystem of partners providing modular and tailor-made solutions for specific project issues) where TSOs can find integrated solutions to all problems (technical and financial) referred to their energy transition projects, also identifying and improving their sustainability impact. Social enterprises gain access to affordable sustainable renovations, coupled with technical assistance, while investors gain access to secure, high impact investments aligned with ESG and impact investment criteria. SER is positioned to strengthen social enterprises and generate more than 500M in clean energy investments over the course of 5 years after the project, translating into nearly 9,000 jobs, 24,633 Co2 emissions saved per year and massive social impact involving energy poverty mitigation, improvements in social inequality, health, wellbeing, productivity, financial literacy, and overall social cohesion. The initial focus is on Italy, with further replication foreseen in Bulgaria and France, and exploratory efforts in Germany, Czech Republic, Slovakia, and Poland. SER Consortium represents an ideal mix of partners including a specialized lender, an ESCO, a financing and de-risking advisory, social impact experts, an energy agency and local replicators in Bulgaria and France. SER strengthens the non-profit sector – a key driver in achieving a just and fair clean energy transition and a post- COVID-19 recovery.
