Hawaii Electric Light Co. has filed a draft Geothermal Request for Proposals with the Hawaii Public Utilities Commission (PUC) to add up to 50 MW of geothermal power at prices not tied to the cost of oil to help lower electricity costs for customers. The utility says the added power must also blend operationally with other resources, including renewable energy from wind, solar, biomass and hydro.
The RFP is pursuing geothermal technologies that provide renewable dispatchable energy and firm capacity, which means that the utility would be able to schedule and control output from the geothermal plant. The utility says this approach will also provide firm back up for other renewable resources such as wind or solar to help maintain reliable service.
