Mark Nisbet, Xcel Energy’s principal manager for North Dakota, will retire on Jan. 15, after spending nearly 40 years with the company. Xcel has hired Tony Grindberg to take over the position.
Nisbet began working at the company in 1981, building and upgrading substations in the Red River Valley. His career took him to Grand Forks, where he was promoted to Customer Business Officer. His other roles included serving as the North Dakota leader for Customer Operations, Statewide Training Coordinator, and Minot General Manager. He was ultimately promoted to Principal Manager for North Dakota, where he worked for 18 years.
“It’s been an honor and a privilege to spend my entire career with wonderful colleagues here at Xcel Energy,” Nisbet said in a news release.
As Principal Manager in North Dakota, Nisbet played a key role in the company’s wind energy expansion in North Dakota, which brought more than 600 megawatts of new wind projects to the state.
Grindberg served as vice president for Workforce Affairs at North Dakota State College of Science in Fargo and led the aviation division at Fargo-based technology company at Appareo, from 2002 to 2012. Grindberg served one term as a Fargo city commissioner from 2016 to 2020, after spending 22 years as a North Dakota state senator, from 1992 to 2014.
