## Data quality

- Published capacity figures differ by measurement or reporting scope: AltaGas lists 507 MW, the CEC lists nominal 520 MW, and an EIA/FERC record lists 591 MW across CT1 at 182 MW, CT2 at 182 MW, and ST1 at 227 MW; these figures should not be treated as interchangeable. The acquisition release separately describes equity, debt, preferred-share financing, and a proposed US$300 million revolving facility; it should not be treated as a standalone construction-project financing amount. The project is listed as operational. Documented post-certification changes include the CAISO transmission intertie and 2014 gas-turbine turndown upgrades; no retirement or repowering milestone is listed in the cited project history.
