Clean energy plans are documents that outline the policies and strategies states can implement to meet clean energy targets. Draft plans are often published first, and after a period of public comments and revisions, a final plan is released.

States can establish some form of statewide, consolidated siting and permitting entity — typically a council or board — for renewables and/or transmission to streamline project review and prevent uncertainty in the face of local governments’ restrictions or prohibitions of renewable generation or transmission.

Advanced transmission technologies (ATTs) and grid enhancing technologies (GETs) are a family of technologies that can enhance the capacity of the existing electrical transmission and distribution system. State policies that promote ATTs and GETs can be key to unlocking renewable energy development at lower cost and with shorter wait times.

Rights-of-way grant certain entities (like utilities) the right to pass through or use a designated portion of another person’s property. States can empower transmission planners and state Departments of Transportation to promote and prioritize projects that colocate transmission lines in existing rights-of-way, such as along highways, to accelerate the siting and construction of new transmission.

Community choice aggregation allows local governments to procure power on behalf of their residents, businesses, and municipal accounts from an alternative supplier while still receiving transmission and distribution service from their existing utility provider.
