ATCO Begins Construction of New Power Station in Karratha

Western Australia Energy Minister turns sod at a special ceremony

 CALGARY, ALBERTA--(Marketwire - March 25, 2009) - ATCO Power today with the Government of Western Australia celebrated the start of construction of a new 86 megawatt (MW) power station in Karratha. Western Australia Energy Minister, Peter Collier turned the sod on what will be the most efficient gas-fired power station in the region.

"ATCO Power is committed to providing additional clean, efficient, reliable power in Australia," said Rick Brouwer, ATCO Power President. "We currently own and operate a 180 MW cogeneration station in Adelaide and a 33 MW cogeneration station in Brisbane. Both those stations provide environmentally friendly power to support businesses and consumers in their respective areas."

The Karratha Power Station will be constructed, owned and operated by ATCO Power and will supply electricity to residential and business consumers on the Pilbara North West Interconnected System (NWIS) under a long-term contract with Horizon Power. The station will be constructed directly adjacent to Horizon's 132 kilovolt substation giving it a direct link into the local network.

Horizon Power Managing Director Rod Hayes said the power station will bring added security to the North West Interconnected System. "With the rapid growth of the NWIS and the increasing demands of energy consumers in the Pilbara, the Karratha Power Station will play a vital role in maintaining a secure and reliable power system," Mr. Hayes said.

The new station - ATCO Power's 20th throughout the world - will be built to an initial capacity of 86 MW but will be designed to allow for expansion to meet the growing needs of the region.

Minister Collier was positive about the long-term benefits of the project for the local community and the State. "This project will be a central component of the ongoing development of the region and its continuing contribution to the State," Minister Collier said. "It not only creates employment opportunities for the construction workforce, but long-term will make a significant contribution to the local community."

The power station will initially be comprised of two 43 MW high-efficiency gas turbines and can be augmented with a heat recovery steam generator (HRSG) that will generate electricity from waste heat. The HRSG would enable the plant to generate approximately one-third more electricity for the same amount of fuel.

The first power is scheduled to be produced by February 2010 with the station operating at full capacity by second quarter 2010.

Horizon Power is the state owned energy company created by the Government of Western Australia in 2006 to meet the needs of residential and commercial electricity customers and resource developments in regional Western Australia. Horizon Power is the energy provider for 31 regional towns and a growing number of rural communities. It is responsible for generating or procuring, distributing and selling electricity to approximately 37,000 customers and major industry in the West Pilbara region.
