KPLP Plant

A History of Reliable Energy Production


Kalaeloa Partners is a model for how a reliable, efficient electric power plant should be run.

Construction on the plant began in 1989 when it was known as the Kalaeloa Co-generation Plant with a top power output of 180 megawatts. In 1991, it began commercial operation as a combined-cycle co-generation plant combusting low sulfur fuel oil (LSFO) to produce electricity and process steam.

PSEG and Harbert acquired the plant from ABB Energy Ventures in 1997. The plant is located in Kapolei on the Island of Oahu, 25 miles west of downtown Honolulu. Kalaeloa Partners now delivers up to 208 MW of power each day to Oahu’s electrical grid.

Kalaeloa is home to a diverse team of professionals, from engineers and mechanics, to instrument control technicians, plant operators, and administrative professionals.

Harbert Management Corporation (HMC) has been part of the ownership of KPLP since 1997 and has owned power generation facilities throughout the U.S. since 1986.  HMC acquired PSEG Power’s 50% interest in Kalaeloa Partners, L.P. (KPLP) on August 10,  2023 and is now owned by Harbert Infrastructure Funds VI, LP (“HIF VI”)

On November 23, 2022, the State of Hawaii Public Utilities Commission (PUC) approved Kalaeloa Partners LP’s (KPLP) Amended and Restated Power Purchase Agreement (ARPPA), which extends the term for another 10 years, reduces the pricing for firm capacity and energy delivered to Hawaiian Electric Company, Inc. (HECO), and provides for upgrades to KPLP’s facility to maintain its exceptional reliability and availability.

Kalaeloa Partners is committed to helping Hawaii achieve its renewable portfolio standards.

Co-generation technology gives Kalaeloa the flexibility to use renewable fuels, reducing emissions and making us one of the cleanest and most efficient energy plants in the state.


It takes an experienced and dedicated team to keep the plant’s systems running smoothly.

Our Team

We are a diverse team of 30-plus professionals who bring deep expertise to Kalaeloa Partners. From plant managers and engineers to mechanics and instrument control technicians and administrative professionals—it takes an experienced team to keep the plants’ equipment and systems running smoothly 24/7, 365 days a year.

Since beginning operations over 30 years ago, Kalaeloa has worked to deliver on its commitment to provide reliable power to Oahu. Along the way, we became one of West Oahu’s long-term employers, providing stable, high-paying jobs. Many of our team members have been with us for decades, and their longevity contributes to a true sense of ohana within Kalaeloa and in the surrounding community.
