The City of Beaverton was awarded $355,420.80 by the Energy Trust of Oregon (ETO) to enter into a Power Purchase Agreement (PPA) for a 420 kW solar system on the Sexton Mountain Reservoir. Sun Edison recently completed the installation of the solar array system and it began generating power on August 17, 2015. There is an estimated annual savings of $95,000 in energy costs over the first 20 years. Then, the City has the option to purchase the system at fair market value.
Assuming purchase, the City expects to save approximately $840,000 over the life of the project. After 20 years, the City can remove the panels, buy them, or extend the agreement. This will allow the City to receive lower-cost electrical power rates and save taxpayer dollars, while utilizing solar energy to help offset the pumping of drinking water to residents on the west side of Cooper Mountain.
The Sexton Solar Tool can be used to track the solar system, and provides data such as the lifetime energy generated and the lifetime CO2 emission offset. This project is expected to prevent 756,220 lbs. of CO2 per year from entering the atmosphere through utilizing clean energy. This is equivalent to keeping 72 passenger vehicles off the road each year or preventing 123 tons of waste from being sent
