April 24, 2008

CALGARY, ALBERTA--(Marketwire - April 24, 2008) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced it plans to spend approximately $55 million on projects to increase volumes and boost efficiency at its Harmattan Complex located approximately 100 kilometres northwest of Calgary, Alberta. AltaGas will invest $24 million to construct on-site facilities and build a 30-kilometre pipeline between its Harmattan Complex and a gas plant in the Carstairs area of southern Alberta. It will also commission a new gathering system to the West and extend an existing gathering system to the North, spending a combined $7 million. A further $24 million will be directed to efficiency enhancements to reduce operating cost and increase reliability at the complex. "Our gas business is growing," said David Cornhill, Chairman and CEO of AltaGas. "Our Harmattan Complex is the best choice for natural gas processing and NGL extraction in the Caroline - Crossfield corridor." He added, "We continue to develop and maximize our existing assets to offer cost-effective solutions for our producer customers." The processing volume is expected to increase by 30 to 40 Mmcf/d and will increase AltaGas' extraction volumes by 1,800 to 2,400 Bbls/d when the projects are completed. The non-AltaGas owned Carstairs area facility will be reconfigured as a compressor station delivering raw gas to Harmattan. Further opportunities to build on Harmattan's strategic location via the consolidation of other gas plants in the area are being actively evaluated. The Carstairs pipeline is subject to regulatory approval and is expected to be in service in the fourth quarter of 2008.
