On Thursday April 22, 2016, Ken Donohoo of ONCOR, Director (Power) System Planning, presented a joint AEP/ONCOR project in West/Far West Texas. This project has been submitted to ERCOT RPG for review.
The project addresses the significant load growth in the area, particularly oil and gas, and coincides with the need to support the large amount of solar generation development in the area. It includes several 69 and 138 kV line upgrades, new 138 kV lines, other substation and transformer infrastructure, and most of all a 345 kV Backbone for the area. The 345 kV lines will “Reach out to areas where there is extreme load and generation growth, but there is lack of adequate transmission grid infrastructure”.
The proposed project will “Provide reliable service to current and future load, relieve planning criteria violations including overloading and voltage collapse with loss of load, support continuing oi/natural gas load growth, provide export capability for new and existing generation, increase reliability & Operational Flexibility, provide injection sources [stations] to aid short circuit strength limitations and meet system protection requirements…”
