DOE-oriented reporting on the project indicated that the capture facility could maintain the targeted capture rate (~4,700 tCO<sub>2</sub>/day) when operating at full output, but that achieving an annual 85% capacity factor was challenging for a first-of-a-kind (FOAK) system.<ref name="IEAGHG2020" /> Over the three-year demonstration period referenced in the DOE/IEAGHG summary, the capture facility reportedly captured 3.54 million tonnes of CO<sub>2</sub> (with multiple factors affecting uptime, including outages at the capture plant, host coal unit, cogeneration facility, pipeline constraints, and West Ranch’s ability to receive CO<sub>2</sub>).<ref name="IEAGHG2020" />

Contemporaneous media reporting also highlighted reliability constraints. Reuters reported in 2020 (citing a technical report submitted to DOE) that the project experienced outages on 367 days since startup, including outages attributed to the capture facility and the dedicated natural gas power unit.<ref name="ReutersProblems2020" />

In February 2025, ENEOS Xplora stated that Petra Nova had “safely captured, transported and sequestered” more than five million metric tons of CO<sub>2</sub> cumulatively.<ref name="ENEOS2025" />
