This IDC Energy Insights report provides an in-depth look at the micro concentrating solar power (CSP) plant Holaniku at Keahole Point, located in Kailua-Kona on the Big Island of Hawaii. The pilot plant produces 2MW of thermal energy that can be used to generate up to 500kW of electricity through an organic rankine cycle (ORC) power block, and the site includes up to two hours of thermal energy storage. The plant was designed by Hawaii-based Sopogy Inc., as were the solar collectors used in the plant. Development of the plant was carried out by Keahole Solar Power LLC (KSP), a Sopogy spinoff. KSP has a 10-year power purchase agreement (PPA) for the output of the plant with the Hawaiian Electric Light Company (HELCO). This report identifies the objectives, the major drivers behind the company's decision to undertake this project, a description of the implemented solution, the business value and the major lessons learned.
According to Jay Holman, lead analyst for IDC Energy Insights' Renewable Energy Strategies program, "The HKP project was an important test of the feasibility of the micro CSP approach in general, and Sopogy's approach in particular … only time will tell if the company will be able to compete in a world of rapidly falling costs for PV plants."
