Electric Utility Assistance and Support

NREL provides data-driven support, assistance, and tools to electric utilities to help further the integration of renewable energy and energy efficiency technologies into the electric grid.

Distributed Generation Interconnection Collaborative

The Distributed Generation Interconnection Collaborative aims to share knowledge on distributed photovoltaic interconnection practices and innovation. The collaborative hosts monthly informational meetings on interconnection topics chosen by participants. Learn more and become a member.

Energy Systems Integration

Using its new, state-of-the-art Energy Systems Integration Facility (ESIF), NREL is exploring the concept of energy systems integration evaluating  the relationships between electricity, thermal, and fuel systems and data and information networks to find ways to ensure optimal integration and interoperability across the entire energy system.

Electricity Integration

NREL's electricity integration activities enable the testing of renewable energy technologies and how they might be fully integrated into grid planning and operations—from ultra-high-voltage transmission systems to medium- and low-voltage distribution grids. Learn about our grid modernization research.
