AltaGas Secures Supply Agreement with Encana to Construct Natural Gas Processing Facility in Montney Resource Area

November 04, 2010

CALGARY, ALBERTA--(Marketwire - Nov. 4, 2010) - AltaGas Ltd. ("AltaGas") (TSX:ALA) today announced it will be constructing a 120 Mmcf/d gas processing facility and an associated gas gathering system in the Gordondale area of the Montney resource play, approximately 100 km NW of Grande Prairie, Alberta. The plant will be equipped with liquids extraction facilities to capture the natural gas liquids value for our customers.  "The Gordondale gas processing facility is an exceptional gas infrastructure project located in an area of strong natural gas supply growth that will provide long-term, stable cash flows," said David Cornhill, Chairman and CEO of AltaGas. "The project is consistent with our strategy to optimize our existing base business and to partner with leading North American natural gas producers."  The Gordondale gas processing facility and gathering system will cost approximately $235 million. The gas processing facility is expected in-service in late 2012. By using existing infrastructure in the area, AltaGas anticipates providing processing for early production by mid 2011. The project is subject to regulatory approval.  AltaGas has secured a long term, gathering and processing agreement with Encana Corporation to supply natural gas to the new Gordondale processing facility.  "The continued strength of natural gas liquids prices offers Encana opportunities to capture additional value and enhance project returns by stripping the propane, butane and ethane from the extensive liquids-rich production in our deep basin resource plays," said Mike Graham, Encana's Executive Vice-President and President, Canadian Division.  The plant is located in the Montney resource area, one of the largest, low cost, liquid rich resource plays in the Western Canadian Sedimentary Basin. This plant will allow AltaGas to provide a midstream solution to a number of producers in the area. The addition of deep cut facilities to the project allows producers to extract additional value for liquids from the gas they bring to the plant for processing. The natural gas liquids extraction facilities also allow AltaGas to expand its service offering to market liquids for customers, and to purchase gas at the plant gate and extract the value of the liquids.  Encana is a leading North American natural gas producer that is focused on growing its strong portfolio of prolific shale and other unconventional natural gas developments, called resource plays, in key basins from northeast British Columbia to east Texas and Louisiana. A pure-play natural gas company, Encana applies advanced technology and operational innovation to reduce costs and maximize margins. By partnering with employees, community organizations and other businesses, Encana contributes to the strength and sustainability of the communities where it operates.
