Kalaeloa Cogeneration Plant - Hawaii, USA

In 1997, PSEG and its partner, Harbert Power Corporation of Birmingham, Alabama, acquired the Kalaeloa Cogeneration Plant (Kalaeloa) in Hawaii. The plant is located 48 kilometers from downtown Honolulu, the state capital and the economic center of Hawaii, on the island of Oahu.

Kalaeloa provides 90 percent of the refinery's thermal requirements and supplies approximately 20 percent of the entire island electrical generating capacity.  The plant's output is critical for meeting the energy needs of Oahu, the third largest and chief island of Hawaii. 

In addition to ensuring a reliable supply of power to the highly urbanized island of Oahu, Kalaeloa is helping to protect the environment. Kalaeloa is pioneering the use of reclaimed water rather than drinking water, thereby conserving valuable water resources, drastically reducing waste water effluent discharged to the ocean and significantly reducing the use of chemicals.

PSEG Power Ventures has general management responsibility for the facility. Operations and maintenance is performed by a third party vendor under long-term contract to Kalaeloa.

Combined Co-Generation:

The most efficient way of generating energy with combustion turbines, Kalaeloa Partners' combined cycle co-generation technology produces two types of useful energies—electricity and steam—with the same source of low sulfur fuel oil (LSFO). 

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

A portion of this steam is then used to run a steam turbine generator and produce additional electricity to power up 50,000 homes without additional energy and with zero pollution. The other portion is used at a local refinery for its processes.

Benefits to Hawaii:

Energy Efficiency

As one of the cleanest and most efficient energy plants in the State, Kalaeloa Partners L.P. generates more energy with less fuel oil, thus produces fewer emissions. Compared to traditional power plants, Kalaeloa Partners’ high tech combined cycle co-generation system uses 500,000 to 700,000 barrels less fuel oil each year to help meet O‘ahu’s energy needs.

Protecting The Environment

Kalaeloa Partners is committed to doing our part to help protect Hawai‘i’s beautiful environment. By employing co-generation technology, we are burning less fuel, reducing emissions and minimizing the environmental impact.

Kalaeloa Partners, L.P. (KPLP) is the only plant in the United States which burns LSFO, which is a left over product after crude oil has been refined by the refinery, with combustion turbine technology, thus combining a rapid response to grid fluctuations with inexpensive fuel. KPLP covers a variety of fuel types it can burn such as gas, diesel, LSFO, including a variety of bio fuels. KPLP has also invested in a Solar Photo Voltaic System at the cogeneration plant further increasing the plant’s output with clean and renewable energy.

As the first company in Hawai‘i to use reverse osmosis recycled water in its operations, Kalaeloa Partners is also helping to preserve Hawai‘i’s limited water resources. By choosing to use the industrial-grade water processed and recycled from wastewater, Kalaeloa Partners saves the island half a million gallons of drinking water each day!

Reliability

As the source of approximately 20% of the electricity needed for the island of O‘ahu, combined cycle co-generation represents a excellent solution to the challenge of achieving a sustainable energy future for the people of Hawai‘i by simultaneously producing electricity, heating and cooling in one single process. With an overall efficiency as high as 70%, co-generation is a reliable and proven means of generating power while cutting 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.
