Allstream Insiders Summary
Xcel Energy has announced separate agreements to sell its Michigan natural gas operations to SEMCO ENERGY Gas Company and its Michigan electric operations to Upper Peninsula Power Company, or UPPCO. According to the companies’ October 6, 2026, announcement, the proposed transactions cover customers in Gogebic and Ontonagon counties in Michigan’s Upper Peninsula.
If approved by regulators, approximately 6,000 natural gas customers would transition to SEMCO and approximately 9,000 electric customers would transition to UPPCO. The companies expect the transactions to close in 2027, following required state and federal approvals.
The announcement does not disclose the purchase price, the exact regulatory approvals required, a closing date, or detailed gas-system asset information. UPPCO separately reported that its proposed electric-operations purchase includes 470 miles of distribution lines, 110 miles of transmission lines and Xcel Energy’s existing Ironwood service center.

How the proposed transaction divides the Michigan operations
The companies have divided Xcel Energy’s Michigan operations by utility service. SEMCO is the proposed buyer for the natural gas operations, while UPPCO is the proposed buyer for the electric operations. The companies said the affected customers are located in Gogebic and Ontonagon counties.
Both portions of the transaction remain subject to regulatory review. The announcement says the transition will occur gradually after required approvals are received, and the companies currently expect closing in 2027. It does not identify a fixed effective date or say that either transfer has closed.
What UPPCO has disclosed about the electric-operations scope
UPPCO’s transaction information identifies 470 miles of distribution lines, 110 miles of transmission lines and the Ironwood service center as part of the proposed electric-operations purchase. Those figures relate to UPPCO’s proposed acquisition of Xcel Energy’s Upper Peninsula electric operations, not to the natural gas transaction with SEMCO.
The shared announcement does not provide comparable mileage, facility or asset details for the natural gas operations. It also does not describe the condition, age, capital plan or individual locations of either company’s proposed assets.
What customers have been told during the approval process
The companies said service would continue without interruption during the transition and that there would be no immediate changes to billing, rates or customer-service processes. They said customers would receive advance notice of any future changes.
Those statements describe the companies’ transition plans while the approvals are pending. They do not establish future rate treatment or operational arrangements after closing, which will depend on the regulatory process and the eventual implementation of the transaction.
What has not been disclosed
The announcements do not disclose transaction consideration, a definitive close date, detailed gas-system assets, individual substations, line segments, customer-account arrangements, employee-transfer terms or a project-level investment program. They also do not identify construction work, equipment awards, suppliers or procurement packages.
Additional regulatory filings and transition updates would be needed to clarify the terms and execution details of the proposed sales.
Allstream perspective: utility transfers remain contingent on approvals
The planned transaction is a regulated-utility transfer, not an announced expansion or construction program. The available disclosures establish the proposed allocation of gas service to SEMCO and electric service to UPPCO, along with the reported electric-system mileage and a 2027 closing expectation.
Until state and federal reviews are complete, the sale should be tracked as a pending transaction. The public disclosures do not support conclusions about new infrastructure spending, awarded work or operational changes beyond the companies’ stated transition plans.
