Shared Solar FAQ
Learn more about our Shared Solar program.
What is the Shared Solar program?
Shared Solar is an easy way for you to get the benefits of locally generated solar energy to power your home or business. Now you can support solar even if you rent or have a shaded roof.
The program offers customers local, cost-effective solar energy. Participants reserve a portion of the electricity produced from a large solar array over its 25-year lifetime. The power from the Shared Solar project is delivered to MGE's electric grid, replacing electricity generated by fossil fuels or other sources.
Where is Shared Solar located?
MGE partnered with the City of Middleton to build the first system on the roof of the City's Municipal Operations Center (MOC), east of and visible from Highway 12, on the north side of Middleton.
An expansion of the Shared Solar program, with a second solar installation, will be built at Morey Field in Middleton. The 3.5-megawatt (MW) expansion of the program allows for additional customers to participate in Shared Solar.
How much electricity is produced?
The array located on the MOC has a capacity of 500 kilowatts (kW). Given the type and efficiencies of solar panels and other project components and our region's solar exposure, we have generated about 640,000 kilowatt-hours (kWh) annually from the project.
The program's share of the installation at Morey Field will have a capacity of 3.5 MW.
Are participants paying to own part of the solar array?
No. Participants reserve a portion of the electricity produced from the solar project over its 25-year lifetime.
Is the power delivered directly to the homes or businesses of participants?
The power from the Shared Solar arrays is delivered to MGE's electric grid. It replaces electricity that would have been generated by fossil fuels and other sources.
What if a storm damages the solar panels?
We do everything we can to make repairs and to restore the solar system to optimal performance. Damage to the solar project will not cause participants to lose power. MGE will continue to meet the energy needs of the participants with other resources as long as there is no damage to the electrical system feeding their homes.
Can I monitor the solar project's energy production over time?
Yes, you can monitor the energy production of the solar array at the MOC at mge.com/sharedsolarproduction. We expect the new solar array's production data will be added after it becomes operational.
What’s the difference between Shared Solar and MGE’s Green Power Tomorrow (GPT) program?
Both of MGE’s renewable energy programs provide eligible electric customers with the opportunity to receive some – or all – of their electricity from clean energy sources. GPT supports wind energy generation in our region. GPT customers pay a penny more per kilowatt-hour (kWh) and can select a fixed dollar amount or a percentage of their monthly energy use (1% through 100%) to purchase under GPT.
Eligible electric customers who would like to power their homes or businesses on 100% renewable energy can participate in both our Shared Solar and GPT programs.
How does Shared Solar fit with MGE's Energy 2030 framework?
This community solar program was designed by MGE with help from our customers. Shared Solar is an example of the types of innovative programs, products and services through which we are partnering with customers to advance our Energy 2030 framework. Beyond Energy 2030, MGE is targeting net-zero carbon electricity by 2050. We'll continue to work with our customers to reach this ambitious goal.
Who can participate in Shared Solar?
Standard residential electric customers and residential time-of-use customers are eligible to participate. Participation will be first come, first served. Under the expansion, customers who have joined the waiting list will be offered participation first.
What happens once the project is fully subscribed?
Once the project is fully subscribed, other interested customers will be placed on a waiting list. If portions of the project become available (previous participant moves out of the electric service area or otherwise chooses to exit), MGE will offer their solar to the next customer on the waiting list.
Can I join Shared Solar if I am in MGE's Green Power Tomorrow (GPT) program?
Yes. When you join Shared Solar, MGE will automatically adjust your GPT purchase to apply only to your electricity use that exceeds the amount of solar power produced by your Shared Solar purchase.
What happens if I move?
Your program participation will transfer to your new residential MGE electric account. Participation ends if you move outside of MGE's electric service area.
Can I cancel my participation?
Yes. You can leave the program at any time. When you notify us, MGE will resume billing you for all your electricity use at the standard rate. The up-front participation fee is nonrefundable.
Can I view the Terms and Conditions?
Participants must complete and sign a Service Agreement. Read an overview of the agreement's Terms and Conditions.
How can I learn more?
Residential customers can call MGE's Home Energy Line at (608) 252-7117 or 1-800-245-1125 Monday through Friday from 8 a.m. to 4:30 p.m.
Are all MGE commercial electric customers eligible to participate in Shared Solar?
Customers who have an electric service meter on the Cg-3, Cg-4 or Cg-5 rate are eligible to participate.
How much energy can I purchase?
I currently participate in the Shared Solar program. Do I need to do anything?
With the project approved, MGE will email you a new agreement for your signature. Upon execution of the new agreement and completion of construction, you will enjoy the benefits of the new Cs-1 rate and the other proposed changes below.
