The National Renewable Energy Laboratory (NREL) over the last year released a multivolume study titled “Storage Futures Study,” hereafter SFS. The high level goal of this is to model energy storage systems’ implementation out to 2050.

Section 3 of this report evaluated the economic potential of diurnal storage. As storage systems penetrated the utility-scale storage market over the last decade, they first penetrated the ancillary services market, which was rather small, then the market for peaking power which was much larger. The next step in this process is to evaluate the economic potential diurnal storage, which is defined as storage with a duration of up to 12-hours. Our Volume 3 of Energy Storage Futures is a summary of Section 3

Great article John, Storage is what the GRID has been missing for 100 years. Now with the new long lasting MegaWatt storage options that is changing very fast. The price is dropping as the batteries get better each year. Even a non renewable GRID  can benefit from storage to be most efficient and make use of the excess power as they can't ramp down and back up to match consumer demand.

Thanks for the comment, Jim.

I don't know if utility-scale storage is at a maximum ramp yet, but in California we have major plans (see link below) but are starting to use storage in lieu of transmission upgrades where this is viable (see second link below).

Also I'm posting the next volume of the above paper tomorrow, and on April 12 I'm posting the next "PV and Storage" paper.
