Kalaeloa Cogeneration Plant - Hawaii, USA

Kalaeloa Cogeneration Plant was acquired in 1997 by Kalaeloa Partners L.P. (KPLP). Public Service Enterprise Group (PSEG) is the managing partner and Harbert Power Corporation is the limited partner of KPLP. The plant is located in Kapolei on the island of Oahu, 25 miles West of Honolulu.

KPLP’s electrical output is 20% of Oahu’s electrical generating capacity, and supplies 90% of the refinery's thermal requirements.

The general management responsible for the facility is PSEG, operations and maintenance is performed by a third party vendor. All together employing 30 individuals from diverse backgrounds.

What is Combined Cycle Co-Generation?

The most efficient way of generating energy with combustion turbines, utilizes a combined cycle co-generation technology. This produced two types of useful energies, electricity and steam, from the same fuel source, LSFO.

Advanced technology captures a large portion of the combustion turbine exhaust heat that would otherwise be wasted by reducing its temperature from 950°F to approximately 350°F, and converting this free energy into steam by means of heat recovery steam generators.

A portion of this steam is used to run a steam turbine generator, producing additional electricity powering 50,000 homes with no additional energy and zero emissions. The remaining steam is used by the refinery for its processes.

Benefits to Hawaii:

Energy Efficiency

As one of the cleanest and most efficient energy plants in the state, KPLP generates more energy with less fuel oil, thus producing fewer emissions.

Protecting The Environment

KPLP is committed to Hawai`i’s renewable portfolio standards by employing co-generation technology, combusting less fuel, reducing emissions, and exploring alternative fuels. KPLP is the only plant in the United States combusting LSFO using turbine technology. Allowing for a rapid response to grid fluctuations, and the use of diverse fuels including gas, diesel, LSFO, and variety of bio fuels.

KPLP is helping to preserve Hawai`i’s limited water resources by utilizing reverse osmosis recycled wastewater in its operations. Replacing the need for half a million gallons of drinking water every day.

Reliability

KPLP provides 20% of the electrical demand for O‘ahu. By producing electricity and process heating in a single process, combined cycle cogeneration represents an excellent solution for achieving a sustainable energy future for the people of Hawai‘i. With an overall efficiency as high as 50% and a lifetime reliability of 99%, KPLP is a reliable and proven means of generating power while reducing costs and minimizing waste.

New Haven Peaking Project

PSEG Power Connecticut built an electric generating peaking facility at its New Haven Harbor station, located at 1 Waterfront Street in New Haven, Connecticut. The new peaking units began commercial operation on Jun 1, 2012. The project represents a $160 million investment in New Haven and provides the City with more than $3 million annually in additional tax revenue.

The project added three highly efficient General Electric LM-6000 combustion turbines at the site of the existing New Haven Harbor facility. These turbines use state-of-the-art technology to provide residents of Southwest Connecticut with power during periods of peak demand for electricity.

The new turbines are dual-fueled and use either natural gas or ultra low sulfur fuel oil. These are the cleanest fuels available.

The project included state-of-the art emissions controls that meet the latest environmental standards. A Selective Catalytic Reduction system and water injection were installed to reduce nitrogen oxide emissions by 90 percent or more. A combustion catalyst has reduced carbon monoxide emissions by 80 to 85 percent.

Peaking units can rapidly produce electricity and are most often used during periods of high demand – for example, during sweltering afternoons when air conditioners are in constant use. The GE LM-6000 turbines at New Haven can reach full output within 10 minutes of being called into service.

As peaking units, these turbines operate only during periods of peak power demand. The facility is helping to improve the reliability of the transmission system by quickly providing power when required by the NE-ISO.

PSEG Power Connecticut is committed to providing the state with reliable and environmentally responsible energy.

The PSEG Keys Energy Center project will be constructed on a 180+ acre parcel of land previously used for a sand and gravel mining operation. The site is located north of North Keys Road approximately 1.25 miles east of Brandywine, Maryland.
