Good reporting. A few more points: 1. In the famous California power mix charts, 'Other' includes power bought from different utilities where the exact generating method is abstracted away. You can mentally think of the 'Other' as 'Unsure'. 2. Intermountain's conversion to natgas has been long rumored, facing both regulatory pressure, environmental pressure, and infrastructure considerations. Large amounts of natgas is already piped through the Kern River Pipeline in this corridor, going to Nevada and California from the Opal hub in Wyoming. This is where Southern Nevada gets most of its electricity -- through natgas power plants alongside I-15. 3. There is a project called TransWest Express [1], to build a HVDC transmission line from Wyoming to Las Vegas to carry wind power from Wyoming to markets in the Southwest. This will run immediately parallel to the existing Intermountain HVDC line for much of their overlap, and no connection is planned at the Intermountain Power Plant (the latter line's origin) or anywhere else between the two for now. Vegas is presumably the destination for TransWest Express because it's a power exchange hub for many electricity suppliers and consuming utilities, but the overall effect is still a bit silly, because most of the power exchanged at the Vegas hub flows towards Southern California anyway on existing AC lines. One might imagine a different scenario where the Intermountain line gets split in two at Vegas, TransWest express only builds the "missing portion" between Wyoming and Intermountain Power Plant, and then there's an available chain of HVDC lines to ship power between 4 key interchange nodes...
