S&C Electric Company PureWave® Storage Management System
Helps Reduce the NOx Emissions on Catalina Island, California
Catalina Island—a historic landmark 22 miles off the coast of Long Beach, California—has a population of approximately 3,700 people. There’s no utility tie to the mainland. The island microgrid has a peak load of 5 MW which is served by Southern California Edison (SCE) through a combination of six diesel generators and 1.4 MW of micro-turbines. The diesel generators were deemed to be high emitters of mono-nitrogen oxide (NOx) gases by the South Coast Air Quality Management District. To mitigate these smog causing emissions, SCE installed emissions control systems which convert the gases into water. But the catalyst for this conversion is only effective at a specific temperature range, which is reached when the generators are run above 80% load. SCE needed a solution that would allow the generators to run more efficiently, and thus reduce NOx emissions on the island.
