On May 24, 2013, Governor Mark Dayton of Minnesota signed into law an energy bill that is projected to greatly increase the state’s solar energy capacity by the end of the decade. Specifically, all utilities in the state must procure 1.5 percent of their electricity from solar generation by 2020, in addition to Minnesota’s existing Renewable Portfolio Standard (RPS) of 25 percent by 2025. Thus Minnesota’s RPS is now effectively 26.5 percent by 2025.

Although 1.5 percent may seem low, compared to Minnesota’s existing solar capacity it is actually quite high. Currently, Minnesota has 13 megawatts (MW) of solar energy capacity, but in order to reach the 1.5 percent standard, the state will have to increase its solar capacity to 450 MW, more than a 30-fold increase. Thirteen other states have solar requirements, or “carve-outs,” five of which have percentage requirements higher than Minnesota. The states with the highest solar requirements are Colorado and New Mexico, each requiring four percent of electricity sold in the respective state to come from solar energy by 2020.
In addition to requiring that 1.5 percent of electricity come from solar resources, HF 956  also includes other solar energy initiatives. The law mandates that the state’s largest utility, Xcel Energy, begin a community solar garden  program, in which people can own shares of a remote solar energy system and earn credit on their utility bill as if the solar panels were on their own homes. In addition, the law increases the maximum capacity for a net meter  from 40 kilowatts to 1000 kilowatts , meaning owners of large solar panel arrays, such as large retail stores, can now be credited for electricity they put back on the grid, reducing their electricity bills. Lastly, the law also mentions a non-mandatory, state-wide goal of 10 percent solar by 2030.
Another energy bill  was recently introduced in Minnesota that would increase the state’s RPS to 40 percent by 2030. This move would make Minnesota’s RPS one of the highest in the country.
