Illinois Distributed Generation Installation Rules

Beginning January 1, 2014, all entities that install distributed generation facilities, with the exception of self-installers, are required to be certified by the Illinois Commerce Commission.

List of ICC Certified Distributed Generation Facility Installers

The rules require each certified company to ensure that its employees, agents or contractors will:

  • Comply with applicable building and electrical codes including those contained in the National Electrical Code;
  •  Install only distributed generation facilities that meet recognized industry standards and comply with manufacturers installation instructions;
  • Comply with applicable licensing and municipal bonding requirements;
  • Allow only qualified persons and/or electrical contractors or persons enrolled in training programs, who are supervised by qualified persons, to install distributed generation facilities.

The Public Utilities Act was recently amended to authorize the ICC to determine what entities are subject to certification requirements and set reasonable certification fees and penalties.  The ICC has also been charged with investigating any violations, adopting procedures for renewal of certificates, establishing conditions for revocation, probation or suspension or other disciplinary procedures.

The rules applicable to distributed generation installer certification can be found on JCAR’s website at:

A Distributed Generation Installer means an organization, institution or individual that has its own existence for legal or tax purposes and is involved in the business of installing distributed generation facilities. Distributed generation facility means the equipment used by an interconnection customer to generate or store electricity that operates in parallel with the electric distribution system. A distributed generation facility typically includes an electric generator, a prime mover, and the interconnection equipment required to safely interconnect with the electric distribution system or local electric power system. Install means to complete the electrical wiring and connections necessary to interconnect the distributed generation facility with the electric utility’s distribution system at the point of interconnection between the facility and the utility.
