Instructions for Submittal of a Large Facility Interconnection Request to the NYISO
Introduction
The NYISO Standard Large Facility Interconnection Procedures (LFIP), contained in Attachment X of
the NYISO Open Access Transmission Tariff (OATT), apply to Generating Facilities that exceed 20 MW
and to Merchant Transmission Facilities. The following instructions are for Developers that wish to
submit an Interconnection Request to the NYISO under the LFIP.1
Submittal of an Interconnection Request to the NYISO
To initiate an Interconnection Request, a Developer must submit all of the following: (i) a $10,000 nonrefundable application fee; (ii) a study deposit of $30,000; (iii) a completed application in the form of
Appendix 1 of the LFIP (see attached); and (iv) demonstration of Site Control or a posting of an
additional deposit of $10,000. To facilitate processing, NYISO prefers these items to be submitted
electronically (fee and deposit(s) via wire transfer, application form and documentation of Site Control by
e-mail). The scanned copy of the completed application and documentation should be submitted via email to: NewProject@nyiso.com
Wire transfers are preferred for making deposits. Please request wiring instructions via e-mail from:
Chelsea Bonesteel
Accounting Associate, Finance
Phone No. (518) 356-8805
E-mail: cbonesteel@nyiso.com
If paying by check, make deposit check(s) payable to: New York Independent System Operator, Inc.
A separate Interconnection Request must be submitted for each site and multiple Interconnection
Requests may be submitted for a single site. A deposit must be submitted for each Interconnection
Request even when more than one request is submitted for a single site. An Interconnection Request to
evaluate one site at two different voltage levels shall be treated as two Interconnection Requests.
Upon Receipt of an Interconnection Request
Within five (5) business days of receipt of an Interconnection Request, the NYISO will:
 Acknowledge Receipt of the Interconnection Request,
 Forward a copy of the Interconnection Request to the connecting Transmission Owner(s),
 Review the Interconnection Request and notify the Developer and connecting Transmission
Owner(s) if the request is determined to be invalid and the reasons for such determination,
 If the Interconnection Request is determined to be valid, provide a form Interconnection Feasibility
Study Agreement to the Developer and connecting Transmission Owner(s).
Within ten (10) business days after receipt of a valid Interconnection Request, the NYISO will establish a
date agreeable to the Developer and connecting Transmission Owner(s) for a Scoping Meeting.

LFIP that will govern.
