Originally estimated to cost approximately $19.5 million annually, Caltrain’s electricity use since the launch of electric service averages 207 MWh on weekdays and 175 MWh on weekends, revising cost estimates to $16.5 million.
With the agency expecting approximately $6 million annually in energy credits from the California Air Resources Board’s Low Carbon Fuel Standard Program, the first year of electric service will have lower fuel costs than the previous diesel service.
