USA, Texas: AEP Texas is set to build one of the first 765 kV transmission lines in the ERCOT region to meet the surging electricity demand in the Permian Basin, a vital center for Texas’ energy production and economic growth. The Howard-Solstice transmission line, a key element of the Permian Basin Reliability Plan, received the green light from the Public Utility Commission of Texas (PUCT) on 24 April 2025.
This large-scale project will involve constructing approximately 480 km (300 mi) of high-voltage line, connecting the Solstice Substation near Fort Stockton to a new substation close to San Antonio. Developed jointly with other entities, the line is designed to increase grid efficiency and ensure reliable power delivery across West Texas.
The initiative aligns with House Bill 5066, signed by Governor Greg Abbott in 2023, requiring ERCOT to implement an electric reliability strategy for the region. The new infrastructure will support both the expanding oil and gas sector and the electricity needs of surrounding communities.
Judith Talavera, president and COO of AEP Texas, emphasized the importance of this step, saying it will help accommodate the state’s continued population and industrial growth.
AEP’s parent company, American Electric Power, operates the largest 765 kV transmission network in North America, spanning over 2,200 miles and including 30 substations in six states.
