ComEd Breaks Ground on New Substation to Accommodate Expected Growth of Data Centers in Elk Grove, Expanding Capacity, Intelligence and Technology

New substation will span over five acres of land

Chicago (October 24, 2019) – ComEd today broke ground on an expansion project at a new substation in Elk Grove, Ill., that is part of a long-range plan to meet an anticipated need for more power in the region, due in part to expected growth and operation of data centers in and around the village's technology park and O'Hare market area. This ground-breaking took place just ahead of International Data Center Day on Oct. 29.

"Elk Grove remains one of the most desirable data center locations in the Chicagoland market, and the nearby Elk Grove Technology Park provides additional sites for growth," said Elk Grove Village Mayor Craig B. Johnson. "Thanks to this ComEd electricity capacity expansion project getting underway, businesses in the area will have the confidence that power requirements will continue to be met and sustained well in to the future."

The new development of the site, the first phase set to be completed by the summer of 2021, will expand capacity of both transmission and distribution systems. An expansion that will bring increased high voltage support, capacity, innovation and intelligence to the village's technology park and O'Hare market area.

 "ComEd actively supports economic development throughout all of northern Illinois and for the 4 million customers we serve.  Substation projects, like the one where we broke ground on today in Elk Grove, will help ensure the electrical infrastructure is in place to meet the region's growth and future energy demand," said Melissa Washington, Senior Vice President of Governmental and External Affairs. "We look forward to working with prospective businesses like data centers and other industries who thrive in Elk Grove and who are also interested in moving their companies into the area."

ComEd has multiple existing substations serving customers in the area and goes through an annual planning process to assess expected load growth based on economic forecast modeling and actual customer usage. The Elk Grove substation is fulfilling a plan introduced in 2017.
