MADISON GAS & ELECTRIC CO

Madison Gas & Electric Co. blends natural gas distribution, retail electricity supply, and energy-efficiency services for households, municipalities, and businesses in south-central Wisconsin, anchoring its operations in the regulated SIC 4911 electric services arena where rates and capital plans are vetted by regulators. This vertically integrated utility relies on transmission and distribution networks, plus grid modernization, to keep lights on, deliver fuel, and offer conservation programs while balancing commodity exposure and weather volatility against long-term demand. Target customers span single-family homes depending on reliable heating, downtown retailers depending on electricity, and industrial plants requiring coordinated gas and power schedules, so the company engages with the Public Service Commission and federal safety standards to demonstrate compliance. Financing and investment choices closely follow rate-case outcomes, meaning that interest-rate shifts, load-growth uncertainty, or a major storm can materially affect earnings and capital spending.
