Energy System Interconnection Standards | State, Local, and
NLR provides information and resources to U.S. states and communities on interconnection standards—how energy systems can be legally connected to the electricity grid.
The utility will evaluate the system design, its impact on grid reliability, and the safety of its operation. Approval typically results in an Interconnection Agreement, a formal document granting permission to operate (PTO). Without this agreement, a solar system cannot legally go live. Utility interconnection isn't just paperwork. It affects:
Approval typically results in an Interconnection Agreement, a formal document granting permission to operate (PTO). Without this agreement, a solar system cannot legally go live.

The process can be complex, time-sensitive, and filled with regulatory requirements, so it's important for developers and facility owners to understand the path to successful interconnection.
