By exposing MP systems to wholesale market electricity prices, FERC-2222 can help activate this bioeconomy and open new revenue opportunities for dairy farms. We demonstrate the impacts of FERC-2222 on the state of Wisconsin, and only for the largest dairy farms; the policy implications for environmental health and phosphorus security could be significantly greater on the national scale, especially if the new infrastructure can find ways to include smaller dairy farms. FERC-2222 creates incentives that simultaneously increase economic welfare and mitigate environmental impacts, and represents an important step in the support of renewable energy, in addressing environmental issues, and in nutrient security.
