Enabling ATTs and GETs
Advanced transmission technologies (ATTs) and grid enhancing technologies (GETs) are a family of technologies that, for a minimal cost, can dramatically enhance the capacity of the existing electrical transmission and distribution system. Since grid capacity is a significant bottleneck to bringing more renewable energy online, state policies that promote ATTs and GETs can be key to unlocking renewable energy development at lower cost and with shorter wait times.
At a technical level, this family of technologies includes advanced power flow controls (which redirect power from overloaded lines to underutilized ones), dynamic line ratings (which use weather conditions to better predict the true amount of power a line can carry), and topology optimization (which uses algorithms to analyze grid conditions and identify optimal paths for power flow). They also include high performance conductors, which are wires that transmit power at higher capacity, greater efficiency, and with minimal thermal sag.
Effective state policy promoting ATTs and GETs ranges across a spectrum. A state may mandate a study of the potential impact that ATTs and GETs may have on reducing the cost of future grid upgrades or accelerating interconnection. In more ambitious scenarios, a state may mandate the consideration of ATTs and GETs in integrated resource planning or grid modernization processes. To incentivize the utilization of ATTs and GETs, states may also offer utility incentives or cost recovery, as well as expedited siting for optimized infrastructure.

Indiana
Electric utilities are required to incorporate advanced transmission technologies (ATTs) into their integrated resource plans starting in 2026. The Indiana Utility Regulatory Commission (IURC) must study ATT use and deployment and include those findings in its 2026 annual report.
Massachusetts
The Massachusetts Energy Facilities Siting Board must determine whether sufficient consideration was given to the use of advanced transmission technologies (ATTs) when reviewing proposals for transmission infrastructure, and the Department of Public Utilities must study the use, costs and benefits, and impediments to ATT deployment.
Utilities must also conduct analyses related to the deployment of ATTs and grid-enhancing technologies (GETs), and they enabled to propose rate incentives to encourage the deployment of such technologies. Utilities must make a filing with the legislature and grid operator every five years on the deployment of ATTs.
Minnesota
Entities that own more than 750 miles of transmission lines in Minnesota must evaluate the technical and economic feasibility of installing grid-enhancing technologies (GETs) to address grid congestion. The Public Utilities Commission can approve cost recovery mechanisms for cost-effective GET investments.
