TransCanada – CSR – Environment: TransCanada’s GTN natural gas pipeline crosses the Pend Oreille River in Idaho. We worked to safely and successfully re-establish river bed support under our pipeline.

Water Water in Power Generation

Our various non-hydroelectric power facilities use water in various ways:

  • Generate steam to create electricity
  • As a coolant in plant processes

TransCanada’s Ocean State Power, Ironwood and Coolidge generating stations utilize a zero-liquid-discharge water treatment system to eliminate any process water discharges to the environment.

When water is used, it is sourced from fresh water, sea water or groundwater sources. The use of water in power generation processes is subject to a prescriptive regulatory, governance and best management framework. When water is returned to its source or discharged to the environment, it has been rigorously tested to meet or exceed all discharge criteria.

Our hydropower assets have a very intimate relationship with water sources, harnessing the raw power of water in the natural environment to create electricity.

The water we borrow in our hydropower process is a precious shared resource and TransCanada takes industry-leading measures to ensure its protection. We have achieved a Low Impact Hydropower Institute (LIHI) certification for the bulk of our hydroelectric generation in New England. LIHI is a non-profit organization dedicated to reducing the impacts of hydropower generation through the certification of hydropower facilities that have avoided or reduced their environmental impacts.
