Sustainable Electricity

MGE generates, purchases and distributes electricity to nearly 155,000 customers. We take seriously our obligation to provide safe, reliable, affordable and sustainable energy.

Our energy supply mix is in transition. MGE is working toward greater use of renewable resources and targeting net-zero carbon electricity by 2050. Like most Midwest utilities, MGE has historically relied upon fossil fuels to serve its electric customers. Our fuel mix, however, is changing as renewable energy technology continues to improve in performance and decrease in cost. MGE is working aggressively to grow our use of cost-effective renewable energy to benefit all our customers.

Our energy future

MGE's carbon intensity will decrease as we continue to transition further toward greater use of renewables. Since introducing our Energy 2030 framework in November 2015, we have developed projects that we expect will increase our owned renewable energy capacity by almost 675% by the end of 2022.

In February 2021, MGE and the co-owners of the Columbia Energy Center announced plans to retire the power plant earlier than initially planned. The plan represents another step in MGE's ongoing transition toward greater use of cleaner energy sources and net-zero carbon electricity by 2050. We also continue to pursue other wind and solar projects to serve all our customers.

Our climate commitment

The Intergovernmental Panel on Climate Change (IPCC) has identified carbon neutrality by 2050 as a benchmark for limiting global warming to 1.5 degrees Celsius. MGE's net-zero carbon by 2050 goal is based on the latest climate science from the IPCC, and our deep decarbonization strategies—clean energy, energy efficiency and conservation, and the electrification of other end uses, such as transportation—are the same as those identified by the IPCC.

Our goal of net-zero carbon electricity by 2050 signals our direction, but it doesn't determine our pace. We're working as aggressively as we can toward deep decarbonization. We believe we can go further faster toward our goal by working with our customers to advance our strategies.

The power of working together

We’re continually evaluating current and new programs to help our customers advance clean energy and manage their energy use. As we transition to greater use of cleaner energy, including through voluntary purchases by our customers who participate in our Green Power Tomorrow and Shared Solar programs, we can partner to reduce emissions by using renewable energy.

Energy efficiency is considered a key strategy for deep decarbonization. Programs like MGE Connect and On Demand Savings help us save energy, manage costs, reduce emissions and better understand the potential for managing energy use using smart technologies.
