Photovoltaic Parks

By Todd Burley and the Sustainable Operations Team

Seattle is a national leader in clean energy thanks to our ample hydropower and local investments in solar and wind power. Yet as our population grows, and electricity demands increase, we need to think creatively about how to provide more power while still maintaining our goals for being carbon neutral by 2050. Seattle Parks and Recreation (SPR) isn't sitting on the side-lines for this transition!

A lot of photosynthesis happens on parklands in Seattle, but there is enough solar power to share. Yes, even in cloudy Seattle the sun can effectively support solar power. In fact, it is estimated that there are about 200 days of sunshine per year with an average of 4.5 kilowatt-hours per square meter of solar potential per day. This is enough to provide most of the power for a smaller home!

SPR owns and manages many buildings that have expansive roofs ideal for adding photovoltaic panels. The old airplane hangers at Magnuson Park are a great example. At the "Brig" building, SPR partnered with the Office of Sustainability and the Environment and Seattle City Light (SCL) to install an extensive photovoltaic system on the roof that produces 33 mWh annually, enough to power three houses.

We also have solar power systems on three picnic shelters at Jefferson Park that add 23 mWh of power back to the grid. And at Carkeek Environmental Learning Center, 36 modules produce enough electricity to power half of that facility's needs. At Mounger Pool, SPR has installed solar tubing to provide solar water heating, seeking to tackle one of our greatest energy draws.

At Miller CC, SPR has partnered with Seattle City Light to install a 50 kW solar microgrid on the roof that is attached to a massive battery bank. This system of 132 modules provides enough power for five houses and independent power during emergencies when the power grid may be down, creating an emergency shelter that can provide services when needed most.

SPR is looking into more solar locations. In 2024 we are conducting a solar feasibility study for six buildings that are slated for renovations. These possible locations include the Green Lake Small Crafts Center, Densmore Headquarters, Langston Hughes Performing Arts Center, Central West District Headquarters, Ravenna Eckstein Community Center, and the Pratt Fine Arts Center.

Seattle is doing a lot to decarbonize our energy system, and SPR is proud to do our part by installing solar energy systems when we can. The future is bright, or as we say #SeattleShines!
