  October 26, 2021
  he project, earlier known as Cardinal Bluffs, will connect ATC’s Cardinal substation in the town of Middleton, Wisconsin, with ITC’s proposed Hickory Creek substation in Dubuque County, Iowa.

• Central East Transfer-Out Transmission Development Project, Canada

  October 6, 2021
  The Central East Transfer-Out Transmission Development Project includes constructing new 240 kV transmission lines by ATCO Electric and AltaLink in the counties of Red Deer, Lacombe and Stettler.

• LRGV System Enhancement Project, US

  October 5, 2021
  Lower Rio Grande Valley (LRGV) System Enhancement Project outlines major improvements to Lower Rio Grande Valley electric grid, including additional 345 kV transmission lines and substations.

• Lake Erie Connector, Canada-US

  September 6, 2021
  The Lake Erie Connector (earlier known as Lake Erie Clean Power Connector) is a 1,000 MW high voltage direct current (HVDC) electric transmission line proposed to connect the power grids of Canada and the United States (US).

• Transmission upgrade project in Warren County, US

  August 9, 2021
  The transmission upgrade project was undertaken to improve the service reliability for customers in the Flowers area of Warren County, US.

• West of Devers Upgrade Project, US

  July 13, 2021
