The PNM Prosperity Energy Storage Project is the nation’s first solar storage facility that is fully integrated into a utility’s power grid.
The project features one of the largest combinations of battery storage and photovoltaic energy in the nation.
The project is part of a nationwide effort to help the economy, develop reliable renewable energy and research battery-storage technology. Partially funded by the American Recovery and Reinvestment Act of 2009, the PNM Prosperity Energy Storage Project is the first ARRA-funded demonstration to go online.
The large, 2,158 panel solar array was funded by PNM customers as part of the PNM Renewable Energy Portfolio Procurement Plan for 2010.
It involves extensive research and development of smart grid
concepts with a number of project partners
including, University of New Mexico, Northern New Mexico College, East Penn Manufacturing and Sandia National Laboratories.
New Mexico companies, SCHOTT Solar, Cameron Swinerton and Positive Energy also made significant contributions to the project.
