CALGARY, ALBERTA--(Marketwire - Nov. 2, 2009) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) is pleased to announce that its Bear Mountain Wind Park is now fully commissioned and connected to the British Columbia power grid. The Park has satisfied the conditions of Commercial Operation Date (COD) and will now receive the firm price under the 25-year energy purchase agreement (EPA) with BC Hydro.

"The completion of Bear Mountain Wind Park is a milestone event for AltaGas and for British Columbia. As the first fully operational wind park in B.C., Bear Mountain Wind Park is adding to the province's supply of renewable energy," said David Cornhill, Chairman and CEO of the Trust.

AltaGas met conditions of COD by satisfying the British Columbia Transmission Corporation (BCTC) certification and grid compatibility requirements, and by successfully completing a 72-hour test which ended October 24, 2009. During the test period, the turbines performed well and the Park produced approximately 2,000 megawatt-hours of energy. "The turbines, substation, and transmission infrastructure are performing as anticipated and the Park is meeting AltaGas' expectations," said Cornhill.

The $200 million project was completed on budget and ahead of schedule. "The success of AltaGas' Bear Mountain Wind Park demonstrates our strategy of investing in and building projects that are long-term, stable assets. AltaGas has again proven its ability to meet complex project development and construction targets on time and on budget."

With a total capacity of 102 MW, the Park will produce enough energy to power most of B.C.'s South Peace region. Under the Government of Canada's ecoENERGY for Renewable Power program, the project will receive a one cent per kilowatt-hour incentive over the next ten years, in accordance with the terms of the agreement. The project includes green attributes, which AltaGas can trade or sell to third parties.

"Bear Mountain Wind Park is a great example of industry, community, and all levels of government, working together to achieve a common goal," said Cornhill. "It has been a delight to work with the people of Dawson Creek and the various governments to bring long-term, clean, renewable wind power to British Columbia."

AltaGas is committed to growing its renewable power generation capacity. With 1,500 MW of wind power opportunities and an additional 400 MW of run-of-river power opportunities under study or development, AltaGas is well positioned to be a leader in clean energy generation.
