The City of Portland’s Green Building Policy requires the incorporation of on-site renewable energy systems into the design and construction of all new City-owned facilities, as practical, or as required by the State of Oregon. The Water Bureau’s Sustainability Action Plan also articulates a goal for the bureau to achieve and maintain a capacity of over 400 kW of renewable energy, including solar and micro-hydro facilities. The Water Bureau has met this goal by installing, or helping to install, 422 kW of renewable energy. These facilities help reduce the amount of fossil-fuel energy that the Water Bureau consumes.


Solar Energy

Interstate Shops & Stores Warehouse
The Water Bureau's newest solar array is a 100 kW array on the roof of the new Shops & Stores Warehouse as part of the Interstate Renovation Project. This array will provide energy for the warehouse and the new Maintenance Building.

Meter Shop Solar Array
A 12.24 kW solar array on the roof of the LEED Gold-certified Meter Shop provides 10 percent of the building’s average annual electricity and is able to generate as much as 15-20 percent of the building’s electricity during summer months.

Groundwater Treatment Building Solar Array
A 9.80 kW solar array is located on the roof of the Groundwater Treatment Building.

Powell Butte Interpretive Center Solar Array
A 7.90 kW solar array was recently constructed as part of the Powell Butte Reservoir Project. This installation will provide electricity to three new buildings at the site – a caretaker’s residence,  interpretive center, and maintenance building.

Solar on the Slough Array
A 267.54 kW solar array at the Groundwater Pump Station is located on bureau land. The system is owned and managed by a third party (Groundwater Solar LLC). Energy from the array provides power to the pump station when it is operating. See HERE for more information on this project.

Solar at Bull Run monitoring stations
The bureau also has four small solar arrays at water quality monitoring stations in the Bull Run watershed. Each array has a capacity of 110 Watts. Using solar technology at remote locations saves money and eliminates the need to use and store liquefied propane gas (LPG).

Micro-Hydro

The Water Bureau installed a 25 kW micro-hydro turbine at Sabin Hydro Park in September 2012. This Vernon Micro-Hydro Project converts energy from moving water into electrical energy. 
 

Hydropower

Two large hydropower facilities are located at the Bull Run dams. They are owned by the Bureau of Hydroelectric Power and are operated by Portland General Electric. For more information see the Bureau of Hydroelectric Power. These facilities generated almost 60 million kWh of electricity in 2013 and this hydropower helps contribute to the region’s mix of renewable power.
