A July 2016 article in Environmental Finance by ARENA Managing Director Greg Kats describes the large current financing gap facing growth stage clean energy companies, and how the ARENA fund structure helps address this gap. A clean energy debt fund leveraging very low cost SBIC debt provides a very promising and scalable approach that complements bank debt and venture capital sources. Rapid expansion of this type of debt financing would help remove a critical financing obstacle to the rapid growth of a generation of clean energy firms, and enable the necessary rapid transition to low carbon economy.
