Nexus Systems Modeling and Analysis
NREL performs cutting-edge analysis and develops unique multisector and multiscale model frameworks to address critical planning and operational decisions at the energy-water-land nexus.
NREL offers the following integrated water systems and energy-water-land nexus modeling and analysis capabilities.
Multisector Planning and Reliability Assessments
NREL performs multisector energy system analyses that have embedded water, land, and other resource constraints into planning and reliability models. NREL has developed in-house models as well as adapted commercially available and open-source models to perform electricity system capacity expansion and production cost modeling integrated with other sector dynamics.
