Power Operations

Power Icon


TransCanada owns or has interests in 11 power generation facilities with combined capacity of approximately 6,600 megawatts (MW) – enough to power more than 6 million homes.

Nearly half of the power we provide is generated from an emission-less nuclear power facility and we are leaders in the development and operation of high efficiency, natural gas-fired generating stations.

Strategy at a glance:

  • Maximize the value of our diverse portfolio of Energy assets through safe and reliable operations
  • Execute capital programs on time and on budget
  • Pursue North American growth in contracted power infrastructure as electric systems move to become less carbon intensive and absorb growing amounts of intermittent renewable capacity
