The Energy Systems Integration Facility, a U.S. Department of Energy user facility, is designed to support grid integration of clean energy technologies.

As an applied lab, the National Renewable Energy Laboratory (NREL) is making an impact on our nation's clean energy goals. Clean energy has been our mission since we were founded more than 35 years ago.

We focus on:

  • Renewable energy generation
  • Sustainable transportation and
  • Energy-saving homes, buildings, and manufacturing.

Our primary research areas are solar, wind, bioenergy, transportation, buildings, analysis, and manufacturing.

We are experts in clean energy resources, technologies, and systems. We develop tools and analytical capabilities to support informed decisions about energy projects, systems, markets, and policies.

Core Capabilities

Our core capabilities include:

  • Chemical, biological, and materials science
  • Mechanical and thermal engineering and
  • Energy systems integration.

NREL has a rich history of scientific innovation and partnering with industry in research and development to bring new products and technologies into the marketplace.

Partners value our objectivity and research-based approach. Working with us enables our partners to meet their goals and targets. We draw upon the deep and diverse expertise of our staff in energy analysis; technology development, transfer, and deployment; and energy systems integration to meet our partner's requirements.

User Facilities

We collaborate with partners who use our unique capabilities for testing technology and integrating energy systems.

  • Energy Systems Integration Facility (ESIF) — A U.S. Department of Energy user facility, ESIF is the focal point for NREL's work in clean energy integration. ESIF is used to design, test, and analyze components and systems to enable economic, reliable integration of renewable electricity, fuel production, storage, and building efficiency technologies with the U.S. electric grid.

  • Integrated Biorefinery Research Facility (IBRF) — The IBRF enables researchers and industry partners to develop, test, evaluate, and demonstrate processes for the production of bio-based products and fuels—all with a focus on reducing performance risk and improving the commercial viability of new processes.

  • Process Development and Integration Laboratory (PDIL) — The PDIL has one-of-a-kind capabilities for fabricating and studying a wide range of solar cell technologies.
