## Data quality

- Capacity is reported differently by source: the CEC and Milepost Power list 240 MW, while an EIA-linked record lists 247 MW and an ARB record lists 247.4 MW of nameplate capacity for generator GE1. Technology labels also differ: the CEC project page labels the project simple cycle, while Milepost Power identifies it as natural-gas combined cycle/cogeneration; the CEC equipment description includes a heat-recovery steam generator and steam turbine. The CEC lists the project as operational. Its 2012 post-certification change concerned natural-gas compression equipment rather than a stated generating-capacity expansion; no retirement or repowering milestone is specified in the cited regulatory history.
