ATCO Northland Utilities Enterprises has been lighting up the North for more than half a century. Its owners include northern investors, the Denendeh Development Corporation (14%) and Arctic Energy Investors (10%). The remaining shares are owned by ATCO Electric.

One of NUE's two operating companies, Northland Utilities (NWT) Ltd., began operations in Hay River in 1951. Today, it provides electricity to 2,500 customers in Hay River, Trout Lake, Kakisa, Dory Point, Fort Providence, Wekweti, Enterprise and Kátl'odeeche First Nation. In 1988, Northland completed a $3.5 million transmission line from Pine Point to Hay River which allows it to buy power from the Talston hydro system. It also maintains a back-up diesel generation plant in Hay River. In the small remote communities, Northland both generates and distributes its power.

The second of NUE's subsidiary companies, Northland Utilities (Yellowknife) Ltd., serves approximately 7,860 customers in Yellowknife and neighboring Ndilo. The company celebrated its 10th anniversary of service in 2003. In Yellowknife, Northland purchases power from the Snare Lake hydro dams for distribution to its customers.

Northland has the operational experience and corporate resources to offer northern businesses a full range of services, including electrical consulting, ownership and operation of power plants; and power plant operations and maintenance for industrial complexes.
