Regulated Energy Delivery

Our utility group, comprised of four utility companies, provides natural gas and/or electric power to approximately 1.19 million customers across eight states.

From 2017 to 2022, our utility rate base grew at a compound annual rate of 8% to a combined $4.0 billion. We expect to invest approximately $2.3 billion from 2024-2028 to replace, expand and modernize our existing infrastructure.

WBI Energy provides natural gas transportation through approximately 3,800 miles of regulated pipeline systems primarily in the Rocky Mountain and northern Great Plains regions of the United States.

WBI Energy’s system is strategically located near five natural gas-producing basins, making natural gas readily supplies available to the company's transportation and storage customers. The system has 14 interconnecting points with other pipeline facilities, allowing for the receipt and/or delivery of natural gas to and from other regions of the country and Canada. WBI Energy owns the largest natural gas storage field in North America, which is adjacent to the Bakken play.

The vast majority of our pipeline business is regulated, providing low-risk, stable returns. From 2024-2028, WBI Energy plans to invest $405 million in its pipeline system, including organic growth projects and system upgrades and replacements with a focus on being the pipeline of choice for demand customers as well as customers in the Bakken.
