Schedule and timeline
TransWest Express LLC conducted a corridor feasibility study to identify the proposed transmission line route and alternative routes, many of which are located within or adjacent to federally designated or proposed utility corridors, or parallel existing transmission lines or pipelines.
In 2008, TransWest applied for rights-of-way over federal lands because the proposed route and the alternative routes for the transmission line crossed federal land that is mainly administered by the BLM and the U.S. Forest Service. The proposed project was considered a major federal action requiring the preparation of an Environmental Impact Statement to meet the requirements of the National Environmental Policy Act. The BLM and Western Area Power Administration were the joint lead agencies responsible for preparing the EIS, and coordinated with about 50 other federal, state and local government cooperating agencies. (To learn more about the NEPA process, check out A Citizen's Guide to the NEPA (PDF).)
The BLM and WAPA sought agency and public input on potential issues to be addressed in the EIS. Based on this input, the BLM and WAPA analyzed the proposed route for the transmission line and reasonable alternatives to that route. After issuing a Draft EIS for review and addressing comments on that draft in 2013, the agencies issued a Final EIS in 2015. A Record of Decision was issued by BLM in 2016 and by WAPA in 2017. Construction of the project will require two to three years, allowing the TWE Project to be in service well before 2030, when California utilities must be procuring 60% of their electricity from renewable energy sources.
