Capabilities

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.
