What MGE Energy does

MGE Energy, Inc. (NASDAQ: MGEE) is a public utility holding company headquartered in Madison, Wisconsin, whose principal subsidiary, Madison Gas and Electric Company (MGE), is a regulated electric and natural gas utility serving approximately 170,000 electric customers across 264 square miles in Dane County and 180,000 natural gas customers across 1,722 square miles in seven south-central and western Wisconsin counties. The company generates, purchases, and distributes electricity and natural gas under rates approved by the Public Service Commission of Wisconsin, with revenue mechanics driven by regulated rate base growth, retail gas deliveries, and equity earnings from transmission investments held through MGE Transco Investment and MGEE Transco LLC in ATC LLC and ATC Holdco. Beyond core delivery, MGE owns generation assets through MGE Power (West Campus Cogeneration Facility in Madison and Elm Road Generating Station in Oak Creek) and is building out a portfolio of utility-scale solar (Darien 25 MW operational March 2025; Nine Springs 8 MW expected 2027), battery storage (Paris 11 MW operational June 2025), and the Columbia Energy Storage Project (18 MW, MGE owns 3 MW) using Energy Dome's closed-loop CO2 long-duration storage technology—the first of its kind in the United States.

The company's business model is a regulated utility franchise: revenue is generated through state-approved rates tied to capital investment in rate base, supplemented by retail gas deliveries and transmission equity income. MGE serves residential customers, commercial customers, and select large energy users including data centers, with state regulatory safeguards ensuring incremental costs from new large customers do not burden existing ratepayers. Adjacent product lines include a Shared Solar community program, MGE Charging Network (public EV fast-charging on 100% clean energy), the MGE Connect smart thermostat demand-response program, Renewable Energy Rider for large commercial customers, and a proposed Commercial EV Charging Allowance (CEVCA). The company has paid dividends for more than 110 years with 50 consecutive years of dividend increases and maintains the highest S&P and Moody's credit ratings among U.S. investor-owned electric and gas utilities. Recent capital actions include a $250 million underwritten common stock offering completed in May 2026 to fund capex, and the company is pursuing regulatory approval to acquire a 33% interest in the RockGen Energy Center natural gas-fired plant (expected close late 2027).

MGE Energy operates with goals of net-zero carbon electricity by 2050 and net-zero methane emissions from its gas distribution system by 2035, supported by capital investment of approximately $1.5 billion in renewable energy and battery storage from 2015-2030 and forecasted near $850 million in generation investment from 2025-2029.
