The LGIP Study Process
The LGIP provides for 3 increasingly-detailed study stages. These explore and refine a design and estimates for a plan of service that will be defined in detail in a Large Generator Interconnection Agreement (LGIA) , following obligatory NEPA
review. The customer participates in meetings that review each study report, and each subsequent study requires the customer to confirm the recommended and agreed-upon decisions arising from the previous stage. The three studies are:
- Interconnection Feasibility Study [FES]
- Interconnection System Impact Study [ISIS]
- Interconnection Facilities Study [FAS]
Each study agreement requires a deposit; descriptions of the studies, the deposits, and associated timelines can be found in this guidance document
Each study report will be followed by a review meeting, which provides opportunities for the Customer and BPA’s team to meet and discuss all the aspects of the proposed interconnection, and to obtain clarity on any outstanding issues. BPA will attempt to schedule these meetings when the Customer is available to meet in person at our Vancouver offices; if that is not possible, conferences by phone can be arranged.
Study reports from existing Interconnection Requests, as well as many transmission system studies, may be requested,
To request a copy of any generator interconnection study report, please email the following information to email@example.com
