Madison Gas and Electric Company: Overview and Service Area
Madison Gas and Electric Company (MGE) is a regulated utility that provides natural gas and electric service to customers in south-central Wisconsin. Headquartered in Madison, the company serves a service territory that spans portions of Dane, Rock, Green, and several neighboring counties. MGE is a subsidiary of Madison Gas and Electric Holdings, Inc., and it operates under regulatory oversight from the Wisconsin Public Service Commission. The company maintains and operates the local electricity and gas distribution systems, including power lines, substations, pipelines, and meters. MGE does not generate a large share of the electricity it sells; it purchases power on the wholesale market and through long-term contracts, while also drawing from a growing portfolio of local renewable resources.

As a regulated monopoly in its service territory, MGE is required to file rate cases with the PSC, where it must justify its revenue requirements and demonstrate that investments in infrastructure are reasonable and necessary. Rate decisions involve testimony from the utility, customer advocates, and the public interest, and they shape the bills that residential and business customers pay. Understanding how MGE structures its rates and services can help customers anticipate costs, take advantage of assistance programs, and participate in proceedings that affect the community.
Electricity and Natural Gas Rates
MGE's rates are divided into several components, including charges for energy delivery, capacity, and the purchase of the electricity itself. For electricity, customers typically see a supply charge that reflects the cost of the energy, along with a delivery charge that covers the wires, poles, and infrastructure needed to move power from the grid to the meter. Natural gas rates include similar delivery charges and a commodity charge tied to the cost of the gas MGE purchases on behalf of customers. Because MGE buys natural gas in bulk and passes the cost through, gas bills can fluctuate with wholesale market conditions, although the company may use rate stabilization mechanisms and hedging strategies to smooth out short-term price swings.
MGE files rate adjustment requests periodically, and the PSC reviews them to ensure that rates are just and reasonable. During rate cases, the utility provides detailed testimony and financial data, and customers can intervene or submit comments. Residential customers also have access to budget billing, which averages out energy costs over the year to reduce seasonal spikes. MGE's rate schedules and tariff sheets are publicly available, and the company publishes explanations of rate components so customers can understand what they are paying for.
Renewable Energy and Sustainability Programs
MGE has invested in renewable energy as part of its long-term resource plan. The company's portfolio includes wind generation assets, community solar projects, and utility-scale solar installations. Customers can participate in programs such as the MGE Share the Sun community solar program, which allows subscribers to benefit from solar energy even if they cannot install panels on their own property. MGE also offers a Green Power Tomorrow program that lets customers voluntarily purchase renewable energy blocks, with the premium supporting new renewable development.
Renewable Energy Targets and Investments
MGE has set goals to increase the share of renewable and low-carbon energy in its portfolio, consistent with state policy objectives and stakeholder input. The company's integrated resource plan evaluates the cost, reliability, and environmental impacts of different resource options over a multi-decade horizon. Investments in energy efficiency, demand response, and grid modernization are part of the same planning framework, and MGE reports progress to regulators and the public through integrated resource planning filings and sustainability reports.
Customer Service, Billing, and Assistance
MGE offers multiple ways for customers to manage their accounts, pay bills, and report service issues. Customers can access online account management, set up paperless billing, and receive automated notifications about outages and payment due dates. For those facing financial hardship, MGE provides payment plans and connects eligible customers with the Wisconsin Home Energy Assistance Program and other utility assistance resources. The company also has a dedicated process for resolving billing disputes and for handling service interruptions, with protections in place for customers who qualify for medical certification or other special circumstances.
Outage Management and Grid Reliability
MGE operates a 24-hour outage reporting system and maintains a workforce trained to respond to storms, equipment failures, and other events that affect service. The company prioritizes restoration based on public safety, the number of customers affected, and the condition of critical infrastructure. MGE also invests in vegetation management, equipment upgrades, and grid sensors to improve reliability and reduce the frequency and duration of outages. Customers can sign up for outage alerts by text, email, or phone, and MGE provides estimated restoration times during widespread events.
How to Participate in Regulatory Proceedings
Wisconsin utility regulation is a public process, and MGE rate cases, tariff changes, and resource plan approvals are open for comment. The PSC accepts filings from intervenors, consumer advocates, and individual customers, and public hearings are held before decisions are issued. MGE's docket information, testimony, and proposed rates are available through the PSC website and the company's own resource center. Customers who wish to follow or participate in proceedings can monitor dockets, submit letters, or file formal interventions, and MGE publishes guides to help stakeholders understand the process and timelines.
