Hawaii Geothermal Transmission & Interconnection(8-HI)

To interconnect a proposed renewable energy project to the existing electric grid, a developer must obtain a Transmission Line Approval from the Hawaii PUC. If the total project costs are less than $2.5 million, the developer doesn’t need PUC approval. The process includes completion of an Interconnection Requirement Study and Power Purchase Agreement to determine necessary upgrades and payment of costs, both subject to PUC approval.
