TORONTO, ONTARIO--(Marketwired - June 11, 2015) - TransCanada Corporation (TSX:TRP) (NYSE:TRP) (TransCanada) today announced that the National Energy Board (NEB) recently issued its decision to the company to proceed with the King's North Connection project as part of approximately $500 million in pipeline and facility expansions within the Eastern Triangle portion of the Canadian Mainline system.

"We are pleased that the NEB has approved our application for the King's North Connection project. The approval of the application will allow TransCanada to move forward with this important facilities expansion, which will provide our customers with the flexibility to source growing supplies of Marcellus gas from the U.S. Northeast," said Russ Girling, TransCanada's president and chief executive officer. "The approval of this project is a great milestone for our southern Ontario facilities expansion plan. We are committed to ensuring that we continue to provide diverse, reliable and economic sources of natural gas while minimizing our environmental footprint and impact to nearby residents and landowners."

The project was developed in collaboration with Enbridge Gas Distribution and Union Gas Limited in an effort to ensure the most efficient design, development and construction of facilities for the area. The project will connect a portion of new Enbridge Gas Distribution pipeline facilities with TransCanada's existing Canadian Mainline system in Vaughan, Ontario. This cooperative strategy will optimize the provision of natural gas pipeline service required in the Greater Toronto Area while continuing to provide homes, businesses, schools and hospitals in Ontario and Eastern Canada with a safe and reliable source of natural gas.

The King's North Connection project is part of the company's $12 billion of small-to-medium sized projects that are expected to enter service by 2017. Beyond 2017, the company continues to advance a number of growth initiatives, including $34 billion of commercially secured projects. Expanding existing facilities allows the company to continuously explore new ways to help producers reach their market.

Construction of the King's North Connection project is expected to cost approximately $220 million and is anticipated to be in-service by third quarter 2016.

TransCanada operates one of the largest natural gas pipeline systems in North America. The shifting supply and demand patterns for natural gas have led to opportunities for new projects to connect emerging supply basins with growing markets. The expansion of TransCanada's southern Ontario facilities demonstrates how the company is responding to changing market needs, building new capacity to meet demand and maximizing the efficiency of the Canadian Mainline system.
