4.C) SolarStone CUP PresentationAbout Us
•Solar based development company,
headquartered in Minneapolis
•Experience
–25+ years of renewable energy development both
domestic and international
–Developed over 3,000 Megawatts (MW) of solar,
wind and hydro energy
–Currently have 22 solar garden projects in for
approval in 13 counties with capacity of 100+ MW’s
Minnesota Solar Energy Legislation
•In 2013 the State enacted the Community Solar
Program to significantly increase the production of
clean energy
•Blueprint:
–Public utilities must dedicate a minimum of 1.5% solar
energy production by 2020 (450 MWs)
–No limits on number of installed
–Solar subscribers must be physically located in a county
or adjacent county
–Each installed solar garden is permitted a maximum
energy capacity of one (1) Megawatt
–Minimum of five subscribers, with no one subscriber
controlling more than 40%
