Buy Wisconsin Solar RECs

through the Legacy Solar Co-op’s Switch to Solar (S2S) Program

The sale of S2S Solar Renewable Energy Certificates (solar RECs) is similar to buying “offsets” except our “offsets” are not traded to allow utility companies to continue polluting our environment. Our solar RECs are retired on behalf of the buyer, so that real and permanent good can come from the use of renewable energy.

How do Solar RECs work?

Each REC represents 1,000 kilowatt-hours of solar-generated electricity and has a (voluntary) market value between $10 and $40 per REC. The Co-op procures its solar RECs locally from solar projects in Wisconsin. Member consumers enjoy a discount, and member producers enjoy preferred pricing for their RECs.

How are Legacy Solar Co-op Solar RECs different?

Some utilities promote “Green Power”, when they are actually selling Renewable Energy Credits for out of state wind and hydro-electric projects carried into Wisconsin over ATC power lines. Often less than 1% even comes from solar projects, while they sell this “Green Power” for a premium of $.02 to $.04 per kWh above what you are already paying. Legacy Solar Co-op will guarantee that your S2S purchase directly supports local solar projects. Member Producers of S2S power are paid a fair price for their local solar RECs (currently at $.02 per kWh, higher than any other green power program).

How do I get Solar RECs?

Solar RECs through the Switch to Solar program are sold online through Legacy Solar Co-op’s ordering system. They are sold through a monthly subscription program offsetting the amount of energy you choose. Generally, the Co-op recommends a plan that is closest to your average monthly energy usage. Subscription plans are offered in the increments listed below:

  • 250 kWh/month (appropriate for a small home or apartment)
  • 625 kWh/month (appropriate for an average home or apartment)
  • 1,250 kWh/month (appropriate for a large home or small business)

Check your most recent utility bill for your energy use. If you live in their service territory, you can also use MG&E’s Average Energy Use and Cost for Residential Addresses to look up your information.

The current pricing for Switch-to-Solar customers:

  • Member price = $.03 per kWh (sold in whatever blocks you determine according to your own energy use)
  • Non-Member price = $.04 per kWh

The following form will ask for the approximate amount of energy you use and for your billing information, that’s it. If you have any questions please contact us at or by calling 608-571-4992.

Madison has a strong track record of citizens who are advocates for clean energy and who have shown great enthusiasm for solar energy and initiatives such as solar community gardens.  The good news is that by purchasing Solar Renewable Energy Credits (RECs) through Legacy Solar Cooperative’s “Switch to Solar” program, you can offset most, if not all, of your energy usage for a surprisingly low price.  You’ll directly support your neighbor’s solar installations while simultaneously giving yourself a cleaner carbon footprint.

If you are already using a similar program like MGE’s Green Power Tomorrow, consider switching to “Switch to Solar,” where 100% of the power comes from solar rather than 1% of the power.
