Public Service Co New Mexico
The Public Service Company of New Mexico (PNM) demonstration project installed an energy storage system composed of two elements: a 0.5MW Smoothing Battery utilizing Ultra Batteries and a 0.25MW/0.99MWhr Peak Shifting Battery utilizing Advanced Lead Acid Batteries, both manufactured by Ecoult/East Penn Manufacturing. These two systems combined with a single 0.75MW Power Conditioning System, are coâ€located with a separately installed 500kW solar PV plant, at a utilityâ€owned site, to create a firm, dispatchable, renewable generation resource. This hybrid resource provides simultaneous voltage smoothing and peak shifting through advanced control algorithms, and is capable of easily switching between endâ€ofâ€feeder and beginningâ€ofâ€feeder configurations to demonstrate simultaneous smoothing and shifting encompassing a range of applications.
