Who sets Hawaiian Electric's rates
Hawaiian Electric is investor-owned, so it can change its base rates only by filing a rate case with the Hawaii Public Utilities Commission. The commission holds hearings and takes public comment before it rules, and it usually approves less than the company asks for. Fuel and other pass-through charges can change between rate cases.
Commission contact: Hawaii Public Utilities Commission. How we calculate every figure on this page: methodology.
