Seba also dismisses concerns about baseload, pointing me to the new Solar Reserve110 MW baseload solar plant in the Nevada desert, running on molten salt storage, that will power Las Vegas at night. Meanwhile, increasing efficiencies and plummeting costs of lithium ion (li-on) batteries are already making night-time residential storage of PV and wind power cost-effective. Every year, li-ion battery costs drop by 14-16 percent. By 2020, experts believe that li-on will cost around $200-250 per kilowatt per hour (kWh) in which case, according to Seba: “A user could, for about $15.30 per month, have eight hours of storage to shift solar generation from day to evening, not pay for peak prices, and participate in demand-response programs.”
