Solar & wind variability can require large shifts in generator output Flexibility – Not just reductions in peak demand matter With clusters of renewable generation there can be large local impacts

Smart pricing stalled by the limited availability of customers to respond Can be changed by cheap, standard automation Can build with existing tools ISOs / RTOs calculate day-ahead prices and most can or are working to forecast look-ahead price Exiting FERC Authority for Price Transparency: 16 USC 824t directs FERC to “facilitate price transparency” and “provide for the dissemination, on a timely basis of information about [wholesale] prices … to … the public.” If needed, FERC can “establish an electronic information system” to do so. Available data formats permit utilities to add information on local distribution Tools that empower customers are a key first step in enabling efficient retail pricing
