Minnesota legislators passed the Next Generation Energy Act in 2007 which, in part, established power sector standards for carbon dioxide emissions. As a result Minn. Stat. §216H.03 now provides that no person shall:

• Construct within a state a new large energy facility that would contribute to statewide power sector carbon dioxide emissions;
• Import or commit to import from outside the state power from a new large energy facility that would contribute to statewide power sector carbon dioxide emissions; or
• Enter into a new long-term power purchase agreement that would increase statewide power sector carbon dioxide emissions. For the purposes of this section, a long-term power purchase agreement means an agreement to purchase 50 megawatts of capacity or more for a term exceeding five years.
