US Storage Market Sets Power Capacity Record With Q1 Deployments - or maybe it is a misleading nomenclature?

US Storage Market Sets Power Capacity Record With Q1 Deployments,  The market is still small, but more and more states are getting in on it.   JULIAN SPECTOR JUNE 04, 2019

The U.S. energy storage industry installed a record amount of power capacity in the first quarter of 2019.

The 148.8 megawatts of new grid storage capacity represented a 232 percent growth over Q1 2018, according to the latest edition of the Energy Storage Monitor report produced by Wood Mackenzie Power & Renewables and the Energy Storage Association. The ESM tracks storage in terms of instantaneous power capacity (megawatts) as well as energy capacity (megawatt-hours).

The previous record came during the Aliso Canyon procurements, in which California fast-tracked battery development to respond to a grid emergency. The new record came from business as usual, as more states pursue storage technology to deliver rapid-fire ancillary services, shift solar power for nighttime consumption and provide local capacity without local emissions.

Among the utility-scale projects that are possible to track individually, New Jersey led the quarter with two 20-megawatt/20-megawatt-hour projects that Viridity developed to participate in PJM’s frequency regulation market.

New York also posted a 20-megawatt system for frequency regulation. Arizona utility Salt River Project completed a 10-megawatt/40-megawatt-hour standalone storage project, giving it the second-place ranking for energy capacity.

Observations:

1. Aliso Canyon procurements, in which California fast-tracked battery development to respond to a grid emergency.

The companies collectively brought on-line more than 70 megawatts of energy storage in less than six months. Julia Pyper, Jan 31st, 2017

At 70 MW it is not a storage battery, but rather a stabilizer, grid quality, low voltage ride through, frequency control and a power factor correction application.  The statement above that 70 MW: "...in which California fast-tracked battery development to respond to a grid emergency. " is not true. 

2. Ditto New Jersey and New York 20 MW each – those, again, those are for grid stabilization, grid quality, low voltage ride through, frequency control and a power factor correction application.  Size does matter...

3. Could anyone elaborate why is this misleading nomenclature, for a small set of batteries, is being used to deceive the public???  That is no different from the “Climate Deniers” claim that mankind energy exceeds the Sun’s energy and changing the Earth climate…
