How State Regulators Can Utilize the Latest Legislative Trend to Make Electricity More Affordable and Reliable

This guide by RMI outlines how state regulators in the United States can implement recently passed legislation to deploy advanced transmission technologies (ATTs), such as grid enhancing technologies (GETs) and advanced conductors, to lower electricity costs and improve grid reliability.

• Advanced transmission technologies (ATTs), including grid enhancing technologies (GETs) and advanced conductors, allow utilities to increase the amount of electricity delivered through existing infrastructure by improving the efficiency and safety of power routing.
• There is a growing legislative trend in the United States to accelerate ATT deployment; in the past year, 10 states (seven with Republican governors and three with Democratic governors) passed laws to this effect, adding to six states that already had such laws.
• State ATT legislation generally falls into four categories: planning laws (requiring feasibility studies during resource planning), siting and permitting laws (requiring evaluation during the Certificate of Public Convenience and Necessity process), cost recovery laws (guaranteeing expenditures can be included in the rate base), and general study requirements.
• ATTs can provide significant economic benefits and faster returns on investment compared to new construction. For example, advanced conductors can double transmission flows at less than half the cost of a new line, and a dynamic line rating pilot in AEP's territory cost $0.5 million but yielded estimated savings of $11 million.
• RMI analysis indicates that deploying GETs in five PJM states could save customers over $1 billion annually and accelerate the interconnection of 6.6 gigawatts of new generation.
