KUPEHAU SOLAR
Project Description
174 Power Global proposes to install, own, and operate a 60 megawatt solar photovoltaic energy facility with a four-hour battery (240MWh battery energy storage system, “BESS”) in the ʻEwa – Kunia area of Oʻahu in response to Hawaiian Electric Company’s Variable Renewable Dispatchable Generation Island of Oʻahu 2019 – Request for Proposals.
The photovoltaic solar and energy storage system would be interconnected to the grid on the Kahe to Waiau 138 kV transmission line.
The proposed project consists of :
Solar photovoltaic modules
Solar PV pad-mounted inverters
Pad-mounted battery modules and inverters
Medium voltage transformers
A site controller system
Medium voltage switchgear
Main power transformer
Relaying and telecommunications equipment necessary to safely integrate the project into the existing grid
The project is sited on approximately 200 acres of low-productivity agricultural lands (LSB D and LSB E soils classification), immediately adjacent to the Kahe to Waiau 138 kV transmission line.
The project has been selected to the Stage 2 Final Award Group, and if a Power Purchase Agreement is signed and approved, the project will be authorized under a 20-year Power Purchase Agreement.
