Utility Public Service Company of New Mexico’s (PNM) plan to procure energy from 950MW of solar and storage facilities by 2022 and replace its retiring 562MW San Juan Generating Station coal plant has been handed a boost.  

The cost of battery energy storage in the US fell by 72% between 2015 and 2019 and utilities in the country are set to bring 10,000MW of new grid-connected capacity online in the next two years.
