The Public Service Company of New Mexico (PNM) demonstration project installed an ARRA/DOE funded energy storage system in physical conjunction with a 500kW PV resource (not funded by DOE). All the stated goals in the Project Management Plan have been achieved, if not exceeded. The storage system is now able to automatically acquire real time market pricing, status of PNM distribution feeders, tabular weather forecasts and on site storage system and PV data to make sophisticated, automated control decisions on how to best utilize the batteries and benefit the local and regional grid. The system has achieved its 15% reduction of feeder peak load goal and a dispatchable renewable resource has been created.
