Have you seen any numbers for the life expectancy of grid connected batteries? I heard A solar project in Hawaii expects to replace the batteries every 5 years with daily cycles. So for California it would be $111 million /yr in battery costs. Manageable, but not a trivial amount to be factoring in to the cost of firming up the capacity of wind/solar.
