City of Colville Phase II

Location: Colville, WA

The City of Colville completed their first solar array in 2016, and it quickly became apparent that they would want to take advantage of additional Grant opportunities through the Department of Commerce and the TransAlta Corporation. 

After performing a Preliminary Energy Analysis it became very clear that the City of Colville had a prime location at their Wastewater Treatment Plant for a fixed array to be net metered to that electrical service. 

Apollo was successful in applying for, and securing both solar grants on behalf of the City of Colville. The City has entered into a net metering agreement with Avista Utilities for a 100 kW Fixed Solar Array which will cover nearly 40% of the Treatment Plants energy production.
