mr. harrington talked about. right now, you have a very high water year. you want to know what that does to revenues or city's sales. at other times, you have a very low water year. you want to know what that does to revenues or costs. we work with power enterprise to do that. the model we developed with them involves setting rates for irrigation districts. you know the long-term capital plan costs. probably most importantly is when you serve electricity customers in the redevelopment areas, area, and understanding of what the costs are on an actual basis and the revenues, we build that into the model. as was mentioned, the goal was to get this to the development areas. just really two points on this slide. one was stated, we you have a carbon free resources. these surrounding resources do not have that. because of those, you have a very low costs. if you look at the main points, the costs for the power enterprise averages about 9 cents per kilowatt hour which is very low. pg&e has costs that are much higher, about 15 cents per kilowatt hour. in santa clar
