EcoGeek reports that California is considering mandating utilities provide a level of energy storage embedded within the grid - California Considers Mandated Grid Storage.
Legislators in California have introduced a bill that would require electric utilities to provide grid-scale energy storage in their operations. The bill would call for a capacity of 2.25% of daytime peak demand by 2014 and 5% of peak demand by 2020.
A variety of technologies could be included in the mix to provide grid energy storage, including pumped storage hydro, compressed air storage, utility-scale batteries, and flywheel storage systems.
This may have the indirect effect of encouraging the utilities to promote efficiency measures and to encourage load shifting, in order to lower the amount of storage that would be required.
