Large Generator Interconnection Procedures

This page provides information on submitting a Large Generator Interconnection Request. The Large Generator Interconnection Business Practice contains the complete process.

A Large Generator is a generator, or an aggregation of generators, whose single or combined generating capacity is greater than 20 MW. The interconnection of Large Generating Facilities to the Federal Columbia River Transmission System (FCRTS) is governed by Attachment L to BPA's Open Access Transmission Tariff (OATT).
The LGIP provides the procedural framework for moving from a submitted Request to a completed interconnection for generators larger than 20 MW (nameplate). The different (Interconnection Feasibility [FES], Interconnection System Impact [ISIS] and Interconnection Facilities [FAS]) studies are defined, together with the deposits and timelines required at each stage.  
Submitting an LGIP Interconnection Request:
An LGIP Interconnection Request begins with the submittal of an Interconnection Request in the appropriate form, Appendix 1 to the LGIP.
An initial deposit of $10,000 is mandated; and an additional deposit of $10,000 is required unless the request is accompanied by a demonstration of Site Control. Note that in certain circumstances, delaying the submittal of Site Control documentation may result in these two deposits being non-refundable: section 3.3.1 of the LGIP sets forth the terms. See Payment and Remittance Instructions.
Signed Interconnection Requests may be scanned and submitted as email attachments to; the originals must arrive within 5 business days. Please cc your Transmission Account Executive and the LGIP Administrator on email submittals.You may also submit Requests by Fax or overnight, see the Business Practice for details
The time a request is received establishes its position and its priority within the Interconnection Queue. The Large Generator Interconnection Business Practice contains the complete process.
Once the Request has been reviewed for completeness and validity, a Scoping Meeting will be scheduled. This begins the process of studying the feasibility and scope of the interconnection.
Please read the comments here to ensure that the requesting entity’s name is properly recorded and that any information BPA requires for registering a new entity is provided.
