A As used in this section: 1. "Advanced power flow controllers" means technologies that modulate circuit impedance or other electrical properties to reroute power flows and relieve congestion; 2. "Advanced transmission technology" means a technology that increases the capacity, efficiency, or reliability of electric transmission infrastructure, including grid-enhancing technologies (GETs) such as dynamic line rating, advanced power flow controllers, and topology optimization; high-performance conductors; and other technologies designed to reduce transmission congestion; 3. "Congestion" means a condition in which a lack of transmission line capacity prevents the delivery of the lowest cost electricity dispatched to meet load at a specific location; 4. "Dynamic line rating" means a system that uses real-time or forecasted weather and operating conditions, including wind speed and direction, to determine the transfer capacity; 5. "Grid-enhancing technologies" or "GETs" means advanced transmission technologies that increase the usable capacity of existing transmission infrastructure through hardware, software, or operational tools including dynamic line rating, advanced power flow controllers, topology optimization, and related technologies; 6. "High performance conductors" means a conductor used in an electric transmission system, including carbon-fiber conductors, composite core conductors, and superconductors, and where: a. the conductor has a direct current electrical resistance that is at least ten percent (10%) lower than an aluminum conductor steel reinforced (ACSR) conductor with a similar diameter and weight, b. the conductor has an energy carrying capacity at least seventy-five percent (75%) greater than ACSR conductors of a similar diameter and weight, or c. the conductor has a coefficient of thermal expansion at least thirty percent (30%) less than ACSR conductors of a similar diameter and weight; 7. "Integrated resource plan" or "IRP" means a utility's plan as further defined and established in the Oklahoma Corporation Commission's administrative rules found at OAC 165:35-37 to ensure that sufficient supply-side and demand-side resources are available to meet its obligation to serve and to achieve public policy objectives, including those prescribed by law, rule, or Commission IRP filing, a rate case, or other proceeding in which an electric utility proposes additions or expansions to the transmission system; 8. "Large load user" means an electric customer whose existing or anticipated load materially contributes to transmission congestion or necessitates transmission upgrades; 9. "Topology optimization" means software that identifies switching configurations to reroute electricity and alleviate transmission constraints; and 10. "Utility" means an investor-owned electric utility subject to the ratemaking and integrated resource planning authority of the Oklahoma Corporation Commission, and does not include electric cooperatives, municipal utilities, or other non-investor-owned providers.

B 1 A utility shall analyze, as part of its planning process and in coordination with stakeholders where practicable, the cost-effectiveness and deployment timeline of advanced transmission technologies and GETs. A utility shall analyze: 1. The cost effectiveness and timetable for deployment of advanced transmission technologies as an alternative strategy to meet electric system needs; and 2. Whether the technologies would: a. increase transmission capacity, b. increase transmission efficiency, c. reduce transmission system congestion, d. reduce curtailment of energy generation resources, e. increase reliability, f. reduce the risk of igniting wildfire, g. increase resiliency, or h. increase capacity to connect new energy resources.

C 2 A utility may consult with large load users to identify opportunities for voluntary collaboration, cost-sharing, or customer-funded pilot deployment of GETs to reduce congestion and minimize impacts to the general rate base. The Corporation Commission shall encourage a utility to include the deployment of advanced transmission technologies in an integrated resource plan. In an integrated resource plan, a utility shall: 1. Analyze congestion hotspots to cost-effectively maximize the delivery of energy resources in the near term, including: a. identifying the ten most congested locations on the entity's transmission system, b. estimating the frequency of congestion at each location and the increased cost to ratepayers resulting from the substitution of higher-priced electricity, c. evaluating the technical feasibility and estimate the cost of installing one or more advanced transmission technologies to address each instance of grid congestion, and d. proposing an implementation plan, including a schedule and cost estimate, to install advanced transmission technologies at each congestion point; 2. Include the results of the analysis described in paragraph 1 of this subsection and the analysis described in subsection B of this section in the filing to the Commission; and 3. Include a summary of its existing and planned advanced transmission technologies.

D If the Commission determines, based on the analysis provided by the utility under subsections B and C of this section, that the deployment of advanced transmission technologies is cost effective, the Commission shall approve the utility's recovery of the prudently incurred costs of the advanced transmission technologies.

This act shall become effective November 1, 2026.
