Nancy Pfund is managing partner at DBL Partners, a venture capital firm which specialises in investing in companies and start-ups that offer both rewarding financial returns, and positive social impacts. There have been some serious clean tech companies in DBL’s portfolio, including a pre-IPO investment in Tesla. With this in mind, we spoke to Nancy about how to invest in energy storage wisely and heard her views on the waves of the future. Part 2 to be published tomorrow.
Whilst most of the federal incentive buzz for energy storage surrounds California’s Self-Generation Incentive Programme (SGIP), new bills from Hawaii and Maryland provide insights on how state storage incentives are moving beyond the Golden State.
