AltaGas to Expand Cold Lake Transmission System

November 09, 2006

CALGARY, ALBERTA--(CCNMatthews - Nov. 9, 2006) - AltaGas Income Trust (AltaGas or the Trust) (TSX:ALA.UN) today announced that it will expand its Cold Lake natural gas transmission system located in the Cold Lake area of northeastern Alberta by approximately 18 Mmcf/d. AltaGas will install compression and construct 4 kilometres of 8-inch diameter natural gas pipeline from its existing Cold Lake transmission system to BlackRock Ventures Inc.'s (Blackrock) Orion steam assisted gravity drainage (SAGD) plant.

AltaGas has entered into an agreement with BlackRock, a subsidiary of Shell Canada Limited, for pipeline transportation capacity to serve the Orion plant. Additionally, AltaGas will provide BlackRock with natural gas supply of up to 17,000 GJ per day. Natural gas deliveries to Orion are expected to commence by May 1, 2007. The project will include modifications to AltaGas' existing field gathering and processing and transmission systems in the area, which will reduce overall Cold Lake system compression requirements.

David Cornhill, Chairman, President and CEO of AltaGas said, "This expansion project, while small, is a key example of AltaGas' integrated energy business strategy in action." He added, "Our Energy Services, Transmission and Field Gathering and Processing businesses worked together to develop this project with BlackRock."

AltaGas' Cold Lake operating area integrates the Transmission, Field Gathering and Processing and Energy Services components of AltaGas' business. The Field Gathering and Processing component of the Cold Lake operating area includes over 646 kilometres of gathering pipelines and 27 facilities, including gas plants and compressor stations that gather and process sweet natural gas. After the natural gas is processed it enters AltaGas' Cold Lake natural gas transmission system, which is approximately 250 kilometres in length and has current operating capacity of 80 Mmcf/d. The majority of the gas entering the system is delivered to off-system residential and heavy oil markets. Any gas not sold to off-system markets is compressed and delivered to downstream pipeline systems. AltaGas' Energy Services business markets or exchanges essentially all of the volumes that flow through the AltaGas Cold Lake transmission system.
