Generation Interconnection Process

Generation interconnection requests to PacifiCorp’s transmission or distribution systems are managed by PacifiCorp’s Generation Interconnection department. PacifiCorp highly recommends that potential generation interconnection customers review the information contained on this and associated pages prior to submitting an application for interconnection.

Generator interconnection requests are processed based on the jurisdiction of the request. Requests subject to the jurisdiction of the Federal Energy Regulatory Commission (FERC) are processed according to the procedures set forth in PacifiCorp’s Open Access Transmission Tariff (OATT). Separate procedures apply to generators defined as small (20 MWs or less) or large (greater than 20 MWs).

PacifiCorp’s Small Generator Interconnection Procedures (SGIP) and Large Generator Interconnection Procedures (LGIP) can be found on our OASIS website, click on folder "PacifiCorp OASIS Tariff" from the sidebar menu, then click on the most recent version.

Qualifying Facilities (QFs) subject to the Public Utility Regulatory Policies Act of 1978 will be processed under rules set forth by the associated state. In the absence of state rules, QF requests will generally be processed under PacifiCorp’s OATT procedures and timelines.

Purpose of Generation Interconnection Queue
  • Treat all customers equally and in a non-discriminatory manner 
    • Requests managed in the order received
    • Common interconnection requirements required for all projects
  • Maintain safety of the system
  • Maintain reliability of the system
  • Ensure appropriate cost responsibility for interconnection costs
  • Comply with state or federal regulations and requirements
Facility interconnection requirements

The links below contain PacifiCorp’s Generation Interconnection Policies based on the interconnecting voltage. The policies explain the technical requirements for interconnection of generators to PacifiCorp's power systems. It is based on applicable rules and tariffs crafted by the Federal Energy Regulatory Commission (FERC) and jurisdictional state regulatory agencies.

In addition to providing reliability, this policy is consistent with safety requirements for PacifiCorp employees and the general public.

Pre-Application Report process

Prior to submitting a formal interconnection application, Interconnection Customers proposing to build a project which is 20 MWs or less have the option to request from PacifiCorp a “Pre-Application Report.” These reports are governed by section 51 of PacifiCorp’s OATT, however there is a separate requirement in the State of Oregon for Pre-Application information.

The ‘PreApp’ report as it is known is a snapshot type of report using only readily available information which provides prospective Interconnection Customers high-level information as to the system status, capacity, and interconnection queue where the Customer may have a potential project. As the PreApp is to be returned to the prospective customer within 15 Business days, this short timeline is intended to allow customers to make final site evaluations prior to investing in a formal interconnection application. In using this evaluation tool, prospective customers may see where in the system are superior sites for interconnection, preventing applications (and formal studies) for locations which are non-ideal for interconnection. By preventing applications for non-ideal sites, PacifiCorp also benefits by freeing up resources to evaluate more ideal sites for interconnection.

Current Generation Interconnection Queue
If you would like to view the projects currently in PacifiCorp’s Generation Interconnection Queue please visit OASIS.
Three types of agreements will be required
  1. Interconnection Agreement. This agreement allows you to connect your generator to the power company’s transmission or distribution system, as applicable.

  1. Power Purchase Agreement. This agreement governs the sale of your electricity (does not apply to net metering, see below). If your intention is for PacifiCorp to purchase your power see contact below:
Contact:
Bruce Griswold
503-813-5218
 
Interconnection customers should contact transmission services for interconnection timelines prior to committing to power purchase agreement delivery dates.
 
  1. Transmission Service Agreement. This agreement allows you to move power across the company’s transmission system. In the case of a generator that is selling its electricity to the power company, transmission service is typically contracted for by the company purchasing the power from the generator.

Net metering
Net metering measures the difference between the electricity you buy from us and the electricity you generate using your own solar, wind or other acceptable renewable generating equipment. 

With net metering, you use the electricity you generate first, reducing what you would normally buy from us. If you generate more energy than you use, the excess goes through your electric meter and into the grid.
 
If you decide to participate, you will need to have your renewable generator approved by code. Then, you will need to sign a net metering agreement and we will install a net meter at your location.

Types of generation interconnection:

FERC Jurisdictional (non-QF) Large Generator

Generating facilities larger than 20 MWs which fall under the jurisdiction of FERC will be processed according to PacifiCorp’s OATT Large Generator Interconnection Procedures (LGIP).

Learn more about Large Generation Interconnection »

FERC Jurisdictional (non-QF) Small Generator

Generating facilities which are 20 MWs or less and fall under the jurisdiction of FERC will be processed according to PacifiCorp’s OATT Small Generator Interconnection Procedures (SGIP).

Qualifying Facility or State Jurisdictional

A Qualifying Facility is a project that meets the requirements set forth in the Public Utility Regulatory Policies Act of 1978 and is generally a project generating less than eighty (<80) MW that is selling electricity to the host utility. Qualifying facilities will be processed according to state rules where applicable. In cases where state rules do not apply qualifying facilities will be processed generally according to PacifiCorp’s LGIP or SGIP as appropriate.

Customers proposing to interconnect a qualifying facility are encouraged to contact PacifiCorp prior to submitting an application to ensure the appropriate application is provided.
