New York Interconnection Standards

Date Last Updated8/13/2014
Policy TypeInterconnection Standard
Policy Administrator/Contact OfficeNew York Public Service Commission (PSC)
Policy Initiation Date12/31/1999
Policy SummaryNew York PSC adopted uniform interconnection standards that apply to CHP. The Standard Interconnection Requirements (SIR) have been amended several times, most recently in March 2013. The SIR apply to New York's six investor-owned local electric utilities: Central Hudson Gas and Electric, Consolidated Edison (Con Edison), New York State Electric & Gas, Niagara Mohawk, Orange and Rockland Utilities, and Rochester Gas and Electric. The SIR includes two sets of interconnection and application procedures:
  • Expedited Process. As amended in 2013, systems up to 50 kW are eligible for a simplified or expedited six-step process. Systems up to 300 kW may be eligible for this provided that the inverter based system is UL 1741 certified and tested. Systems proposed to be installed in underground network areas may be required to submit additional information and may subject to a longer review process. Systems up to 50 kW are not charged an application fee.
  • Basic Process. All systems >50 kW and up to 2 MW, and systems >50 kW and up to 300 kW that have not been certified and tested in accordance with UL 1741, applicants must use the basic, 11-step process for interconnection.
Both processes include utility response timelines, applicable fees, and procedures for dispute resolution. Certified, inverter-based systems up to 25 kW are not required to have an external disconnect switch; all other systems are required to have an external discconnect switch. Utilities are required to maintain a web-based system for providing information on the status of interconnection requests to customers and contractors. The requirements specifically state that utilities are not permitted to require customers to purchase general liability insurance; however, the PSC recommends that system owners purchase insurance for their own protection.
CHP Eligibility RequirementsBoth fossil-fueled and renewably-fueled CHP systems are eligible for standardized interconnection.
Eligible Project Size (MW)Standardized interconnection applies to systems up to 2 MW.
