Our nation’s energy landscape is in the midst of a remarkable revolution. Energy systems are becoming increasingly distributed and integrated, and renewable energy projects are helping customers save money, increase resilience, and meet clean energy goals. Given the many technology options available, and complex technical and financial considerations, decision-makers need user-friendly tools to inform strategic energy investments.
Enter REopt. NREL’s free, online REopt platform is designed to help building owners, developers, utilities, researchers, and everyday citizens understand their optimal energy solution.
REopt considers synergies and tradeoffs among a wide range of energy generation, storage, and electrification technologies, and identifies the most cost-effective mix of technologies to meet a user’s energy goals – including cost-savings, resilience, decarbonization, and energy justice. Specifically, REopt works by:
Evaluating the economic viability of distributed solar PV, wind, battery storage, combined heat and power, heat pumps, thermal energy storage, EV charging, and hydrogen technologies.
Identifying system sizes and strategic operations to minimize energy costs.
Quantifying the renewable energy and emissions impacts of these technologies.
And estimating how long these systems can sustain critical loads during a grid outage.
The REopt web tool delivers powerful insights with as few as three site-specific inputs, allowing users to identify a single, integrated, comprehensive energy solution based on the least-cost combination of technologies. Additionally, REopt’s capabilities are accessible through an application programming interface and open-source code, allowing researchers and industry to integrate REopt into their own tools and workflows to further amplify the platform’s impact.
Achieving ambitious clean-energy goals depends on many people making complicated decisions. With REopt, you don’t have to be an expert to unlock expert energy analysis. In just five minutes, users can identify an optimal solution for a site, helping spur transformational clean, resilient, cost-effective energy solutions.
