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.
