Implications of policy-driven transmission expansion for costs, emissions and reliability in the USA
Evaluates the economic, reliability, and climate impacts of minimum interregional transmission requirements on the U.S. power sector. Finds that policy-driven transmission expansion can simultaneously reduce costs, cut emissions, and improve grid reliability.
