AltaGas Announces Start-Up of Acme CBM Processing Facility and Growth in Field Gathering and Processing Assets

November 29, 2007

CALGARY, ALBERTA--(Marketwire - Nov. 29, 2007) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced that the 10 Mmcf/d Acme coal bed methane (CBM) processing facility went into service on November 18. Ember Resources Inc., the producer, has completed its drilling program for the year and, as expected, 31 wells were tied-in. Additional volumes are expected to come online in January.

"We are pleased to announce that our Acme CBM processing plant is now in service - on time and under budget. The plant is already processing 4 Mmcf/d of CBM gas and is expected to ramp up as more production wells are connected over the next few months," said David Cornhill, Chairman, President and Chief Executive Officer of AltaGas. "We are also pleased to announce a further $13 million in growth projects in the Field Gathering and Processing segment, including 5 Mmcf/d of gathering and processing capacity and a new natural gas gathering line."

The Trust expects to acquire natural gas gathering and processing assets in the strategic coal bed methane producing area of Corbett Creek, 150 km northwest of Edmonton, Alberta. AltaGas is acquiring the assets, which include 13 km of gathering lines and a processing plant with a capacity of 5 Mmcf/d, from an independent third-party unconventional oil and gas producer. The acquisition is expected to cost approximately $5 million and supports the Trust's strategy to increase processing of unconventional gas production, particularly CBM. The acquisition will be effective December 1, 2007 and is subject to normal industry conditions precedent.

In addition, AltaGas expects to acquire 100 percent interest in a new 15 Mmcf/d natural gas gathering line in northwest Alberta. The gathering line will be constructed by Fortress Energy Inc. and will connect the Trust's Clear Prairie gas processing facility to the Square Creek area, 250 km northwest of Grande Prairie, Alberta. Construction is anticipated to begin late this year and the 38 km gathering line is expected to be commissioned in the first quarter of 2008. Upon completion of construction AltaGas will assume ownership of the gathering line, which is expected to cost $8 million. Once in service, it is expected that the gathering line will increase throughput at the 15 Mmcf/d Clear Prairie gas plant by approximately 5 Mmcf/d. The agreement is subject to normal industry conditions precedent.
