Go Green with MGE
Reduce your footprint with our optional renewable energy programs.
MGE continues to grow our use of carbon-free electric generation to meet our community's energy needs while working toward net-zero carbon electricity.
We also offer optional programs for customers who want to further reduce their environmental footprint. Two of those options include Green Power Tomorrow (GPT) and GPT Renewable Natural Gas (GPT RNG).
Green Power Tomorrow
MGE's GPT program is a flexible, affordable option for supporting local and regional renewable energy resources and offsetting greenhouse gas emissions from your electricity usage.
Each kilowatt-hour (kWh) of electricity you purchase through GPT is generated by renewable resources, including both wind farms and solar arrays. Those allocated kWh include the environmental benefits, or Renewable Energy Certificates, which are retired on your behalf. GPT is one cent more per kWh. You determine your level of participation at a cost that works for you.
Learn more about GPT and enroll.
Renewable natural gas
MGE's renewable natural gas (RNG) program—GPT RNG—is another sustainable energy option that helps offset the greenhouse gas emissions from your natural gas usage.
Similar to GPT, under our GPT RNG option, you pay an incremental charge to participate. You can select either a set number of therms each month to offset through GPT RNG or a percentage of your monthly usage. Renewable Thermal Certificates (RTCs) are purchased by MGE on your behalf to offset the emissions associated with your natural gas usage. RTC units are added as an incremental energy charge of $1.78 per therm to your monthly natural gas bill.
