Electric Vehicle Supply Equipment, Energy Storage and Solar Permitting and Inspection Guidelines

Guideline / November 23, 2022 / Codes And Policy

In many parts of the United States, navigating building permits required for distributed energy resources such as solar, storage, and electric vehicles (EVs) can be a daunting process.  Under a three-year project, funded by the Department of Energy, NBI has led the development of a series of guidelines to streamline the permitting and inspection processes for distributed energy resources to reduce carbon emissions, save people money, and help balance energy supply and demand on the grid.

These guidelines provide an overview of code requirements for the installation of Electric Vehicle Supply Equipment and Energy Storage Systems (stand alone and paired with simple photovoltaic systems) in single family, multifamily, and office buildings. By providing specific and replicable lists of permitting and inspection requirements, local jurisdictions can streamline the permitting and inspection process by reducing informational barriers while helping ensure the design and installation of these distributed energy resources are consistent, code compliant, and safe.

In 2023, NBI will pilot these guides in several jurisdictions across the country to refine their content.

We’d appreciate any feedback on these guidelines that you would be willing to provide.
