REopt Lite
• The REopt Lite Web Tool offers a no-cost subset of NREL's more comprehensive REopt model
• Beta version of web tool launched September 2017; additional features added through 2018 and beyond
• Financial mode optimizes PV and battery system sizes and battery dispatch strategy to minimize life cycle cost of energy
• Resilience mode sizes PV+storage systems to sustain critical load during grid outages
