Model Interconnection Procedures

IREC first developed Model Interconnection Procedures in 2005 in an effort to capture emerging best practices in this vital area. Several important evolutions in best practices are synthesized into the 2013 Model Interconnection Procedures, last updated in 2009.

The important advances incorporated into these model procedures include:

  • Integrating a pre-application report that provides developers with readily available information on relevant considerations associated with interconnecting at a specific point on the local electric power grid;
  • Updating one of the expedited interconnection screens to allow generators that require limited construction on the utility system to proceed through an expedited review so long as there are no safety and reliability impacts that require additional study;
  • Incorporating location-specific criteria for determining eligibility for expedited interconnection that vary according to the voltage of the line at the proposed Point of Interconnection and distance from the utility substation;
  • Increasing the clarity and transparency of the supplemental review process by establishing timeframes for completing, identifying technical criteria for reviewing applications, and providing a fixed cost;
  • Adding an options meeting prior to entering Level 4 that allows for dialogue between the utility and the customer before studies are conducted;
  • For applications that require study, eliminating the Feasibility Study and embracing a more efficient two study process already in use by many utilities;
  • Updating application fees so that they reflect current costs;
  • Explicitly allowing for electronic signatures on applications and agreements to expedite the administrative aspects of the interconnection process.
