Customer Generation Type

Whether you’re thinking about or moving forward with the installation an electrical generating system, Avista has put together the information you will need to interconnect to our system.  It's important that you contact Avista very early in the process. In some cases, Avista might also be able to offer a Renewable Generation Incentive (RGI) that provides direct payments to help offset and recover costs of renewable energy systems in Washington State. More information on this incentive can be found here.

There are three different interconnection types: 

  1. Net-metered system (Net-metering is allowed up to 100 kW by state law).  The Net-metering agreement is also the Interconnection agreement between Avista and the Customer.
  2. Interconnect to Avista’s electrical system and sell power to Avista under a PURPA or non-PURPA Power Sales Agreement (Interconnection is under State Jurisdiction).
  3. Interconnect a PURPA or non-PURPA project to Avista and wheel energy across the Avista electrical system and sell power to a third party that has the rights to purchase wholesale energy.  (Interconnection is under FERC Jurisdiction).

Detailed below are the three categories of systems with various documents required for interconnection.  Please be sure to read all of the information, as approvals are needed from Avista along the way. You can find out more information about the following:

If you have any questions, please contact the key contacts for either type of system.
