Ripon Cogeneration, which operates cogeneration facilities throughout most of northern and central California, US, says it has achieved a 30% reduction in start-up time for its 50 MW plant by replacing its obsolete distributed control system (DCS) with a new system from Rockwell Automation.
In addition, Ripon said it has reduced the number of nuisance trips by nearly 90% at the 25-year-old gas-fired plant.
The system includes an information-enabled, scalable, multidiscipline control platform that combines process and safety control with communication and state-of-the-art I/O. The system is equipped with 750 I/O points and is able to collect up to 1000 points of process data.
‘Besides significantly reducing costly shutdowns, the PlantPAx system has helped us comply better with state emissions and other regulations,’ said Brett Weber, operations and maintenance manager at Ripon Cogeneration.
