The REopt® platform and web tool analyses can be applied to energy optimization projects that include renewable energy, microgrids, electric vehicles, energy storage, and combined heat and power.

Featured Projects

A map shows the locations and sizes/net present value of renewable energy projects across the United States. The largest yellow circles, located in California, Hawaii, and the Northeast, represent projects with a net present value of $850,000 to $2.2 million. The second largest yellow circles represent projects with a net present value of $350,000 up to $850,000. The third largest yellow circles represent projects with a net present value of $200,000 up to $350,000. Smaller yellow circles represent projects with a net present value of $100,000 up to $200,000. The smallest yellow circles represent projects with a net present value of less than $100,000.

Projects by Topic

The REopt platform has efficiently identified and prioritized renewable energy opportunities across portfolios of properties spanning multiple cities, states, or countries. REopt analysis is tailored to the individual energy requirements, costs, resources, and constraints of each client and site. The platform identifies the most cost-effective and technically viable ways to meet energy goals and the estimated costs to achieve them.

Evaluation and Prioritization of Renewable Energy Projects

Support for Campus-Wide Carbon Reduction Strategies

The REopt web tool empowers energy and facility managers to identify, evaluate, prioritize, and plan their most economically viable renewable energy and energy storage opportunities.

The REopt platform evaluates solutions to reduce operating costs of electric vehicle DC fast charging stations, including coupling stations with energy storage and distributed solar photovoltaic generation, and colocating them behind the meter of existing commercial loads.

REopt evaluates how water treatment and storage systems can be leveraged for economic savings through demand reduction and time-of-use shifting. REopt looks at water treatment and storage in integration with other energy assets and calculates system sizes and operating strategies to minimize life cycle costs.

NREL continues to expand the application of the REopt platform to new areas, including combined heat and power, energy efficiency and renewable energy optimization, demand management, nuclear-renewable hybrid system optimization, and model predictive control.
