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.  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.

Below is the information for the interconnection of two different types of systems. 

1. Systems 300 kW and less
2. Systems between 300 kW and 20 MW

Detailed below under the two categories of systems are the various documents required for interconnection.  Please be sure to read all of the information, as approvals are needed from Avista along the way.  If you have any questions, please contact the key contacts for either type of system.  For systems larger than 20 MW, please contact Warren Clark at 509-495-4186.
