The city next to where I live has just brought a new TESLA power plant on line with the co-operation of SoCal Edison. It is 20 megawatts and can power 2,500 homes for a day. It was brought on line in only 88 days as compared to years! There was no need for water or gas lines to be installed. The batteries were built in the Gigafactory in Sparks,NV which I hadn't even read was in production already.
