The REopt™ techno-economic decision support platform is used by NREL researchers to optimize energy systems for buildings, campuses, communities, microgrids, and more. REopt recommends the optimal mix of renewable energy, conventional generation, and energy storage technologies to meet cost savings, resilience, and energy performance goals.
NREL’s powerful REopt capabilities are available through a free REopt Lite web tool evaluation or a custom REopt analysis.
Use the publicly available REopt Lite web tool to evaluate solar, wind, and battery storage potential at your site.Try REopt Lite >>
