- Status detail: The exact EIA plant is currently operational, with four operational generators totaling 161 MW. The underlying Stanton facility is a 98 MW natural-gas hybrid project with two GE LM6000 turbines and integrated batteries. CAISO records identify Stanton 1 and Stanton 2 as resources STANTN_2_STAGT1 and STANTN_2_STAGT2; a July 2025 CAISO report showed Stanton 2 in a forced/curtailed condition, which is an outage status rather than a retirement or mothball designation. No formally announced retirement, deactivation, seasonal-operation date, or repowering plan is supported by the retrieved records. — Stanton Energy Reliability Center | California Energy Commission · confidence: medium

## Data quality

- EIA plant data report 161 MW and four units, while CEC and project materials describe the SERC configuration as 98 MW with a 20 MW battery system; Commercial-operation dates vary by scope: the gas facility is reported as operating in July 2020, the BESS soon thereafter, and the CEC records the project commercial-operation date as October 6, 2020. A 2018 interconnection filing proposed adding a 20 MW inverter-based battery facility that would have produced a 170 MW project, but the cited filing does not establish the completion date or final relationship of that proposal to the current 161 MW EIA record. Public project materials identify original joint-venture ownership and project financing support, but disclose no buyer, seller, acquisition consideration, sale date, or completed ownership-transfer transaction. The $30 million figure reported by Vanir is identified as construction cost, not as debt financing, sale consideration, or a portfolio transaction value.
