Involve Avista Early

Once you have decided to install your own renewable generation, we strive to make the interconnection process run as smoothly as possible. Contacting Avista and submitting your application early in the process can help ensure a quick and safe installation. The best practice to reduce surprises or slowdowns is to submit your application and receive approval before you obtain your equipment or begin your installation. In some cases, utility upgrades may be required before installation can be completed.
