Brad Rockwell: Kauai Island Utility Cooperative

Brad Rockwell is the executive manager of operations at the Kauai Island Utility Cooperative in Hawaii. In this episode, Robert talks to Rockwell about how his co-op has achieved high penetration of renewable electricity – it now gets about 60% of its electricity from biomass, hydropower and solar – his grid’s use of battery storage, why it will still need oil-fired generators, and the future of renewable electricity on the other Hawaiian islands.
