REopt® Model Overview and Example Use Cases

Summary

NREL's REopt platform is a mixed-integer linear optimization model designed to identify cost-optimal distributed energy resources (DERs) for sites, aiming to minimize energy costs while meeting resilience and emissions goals. The model considers a 25-year analysis period, with an assumed inflation rate of 1.2% and discount rates of 4.2% (direct ownership) or 6.38% (third-party ownership). Key financial parameters include a national electricity cost escalation rate of 1.7%/year and an effective tax rate of 26% for private entities. Specific technology assumptions include a solar PV capital cost of $1,790/kWdc and battery capital costs of $910/kW + $455/kWh, both benefiting from a 30% investment tax credit and 60% bonus depreciation in the first year.
