public service co. of new mexico (pnm) and its research partners are testing and demonstrating numerous benefits of the solar power-storage system at its prosperity energy storage project. the site features 500kw of poly c-si pv panels and 500kw/1 mwh rated battery. the features of the battery include:

smoothing: battery storage provides the ability to “smooth” the output of the solar facility. for example, when a cloud casts a shadow on the solar panels, the advanced battery system and smart grid technology immediately dispatches energy to fill the gap created by the cloud.

shifting: stored energy can be dispatched as “firm” energy when energy demand increases, similar to how a natural gas plant can be used today during times of customer peak usage. this allows pnm to use renewable energy when it’s most needed.
