How It Works
NREL functions as a government-supported national lab with a mission to advance energy transformation through science and innovation. Its researchers develop new materials, design systems, simulate performance, and validate technologies under real-world conditions.
Much of NREL’s work begins in the lab, where scientists use high-performance computing, advanced materials synthesis, and experimental test beds to investigate new solutions. These early-stage discoveries are refined through modeling tools and prototype development. Technologies that demonstrate potential are tested in pilot projects and scaled through partnerships with commercial or government entities.
For example, in solar energy, NREL researchers work on improving the efficiency and durability of photovoltaic cells using materials science. In energy storage, teams evaluate new battery chemistries and grid integration strategies. For buildings, the lab creates simulation models to test how energy systems interact under different usage scenarios.
NREL also provides technical validation for emerging technologies and contributes to national standards. Using its large-scale testing infrastructure, it supports certification of products and systems before they are deployed at scale.
All of NREL’s tools, data, and research are made accessible to stakeholders via its website and collaborative platforms, ensuring that energy developers, city planners, utilities, and governments can apply the findings in practical ways.
Use Cases
NREL’s research and platforms are used across multiple industries and sectors to inform, design, and deploy clean energy solutions:
Utilities and Grid Operators: Use NREL tools and data to plan renewable integration, energy storage, and grid modernization strategies.
Clean Energy Developers: Leverage NREL’s simulation software like SAM and PVWatts to assess project viability and optimize system performance.
Local Governments and Cities: Collaborate with NREL to design net-zero buildings, develop clean transportation infrastructure, and meet sustainability goals.

Academic Researchers: Access high-quality data, publications, and collaboration opportunities in energy science and engineering.
International Development: NREL supports global energy access projects, helping countries implement clean energy policies and infrastructure.
Pricing
As a federally funded research lab, NREL does not sell commercial products or operate under a traditional pricing model. Instead, its services and resources are accessed in the following ways:
Public Access: Most tools, models, datasets, and publications are available for free through the official NREL website.
Research Partnerships: Organizations can engage in collaborative research agreements (CRADAs), user facility agreements, and cooperative research efforts. These are typically negotiated and cost-shared based on the scope and duration of work.
Technical Assistance: NREL offers technical services through U.S. Department of Energy programs, often subsidized or funded by grants.
Startup Support: Entrepreneurs can apply to tech incubators and funding programs like the Wells Fargo Innovation Incubator (IN²) or DOE’s Lab-Embedded Entrepreneurship Programs.
Training and Workshops: NREL occasionally provides specialized training or hosts industry-specific workshops, which may require registration fees.
Custom Research or Validation: Businesses seeking proprietary testing or technology validation can enter into direct agreements with the lab.
Strengths
NREL’s greatest strength is its breadth and depth of scientific expertise across the full clean energy ecosystem. As a trusted, independent research body, it brings credibility and technical rigor to every aspect of its work.
Its role as a non-commercial, data-driven institution allows it to serve as a neutral advisor, making it a critical partner for both public and private entities navigating energy transitions.
The lab’s extensive open-access toolsets and data repositories empower stakeholders worldwide to plan and analyze renewable energy systems with accuracy.
Its integration of theory, experimentation, and field validation ensures that research is not only innovative but also grounded in real-world performance.
NREL’s state-of-the-art infrastructure supports large-scale testing that few institutions globally can match, particularly in grid, wind, and hydrogen energy.
Drawbacks
One challenge with NREL is that its primary audience is technical and institutional, which can make it less accessible to individuals or small organizations lacking technical expertise.
While many tools are free, navigating the complexity of certain models or datasets may require a steep learning curve or support from experienced analysts.
Custom research services and partnership opportunities, though impactful, often require time-consuming negotiation and government oversight, limiting rapid access.
Because NREL is a public institution, it may not always be able to prioritize commercial urgency, especially when projects are aligned with long-term national goals rather than market timing.
Comparison with Other Tools
Unlike private clean energy consultants or commercial software platforms, NREL is a nonprofit public entity focused on advancing science, not selling solutions. Its tools and datasets are publicly funded and freely available, offering unmatched transparency.
Compared to organizations like the Electric Power Research Institute (EPRI), which serves the utility industry, NREL covers a broader technology base including buildings, vehicles, and fuels.
While other labs under the DOE network also focus on energy, NREL is uniquely dedicated to renewable energy and energy efficiency, making it the flagship lab for clean energy innovation in the U.S.
Its models like SAM and ReOpt are frequently used in comparison with commercial project finance software and outperform in terms of technical depth, accuracy, and credibility.
