Project Update (2/26/2020)

Seattle City Light and Seattle Parks and Recreation hosted an open house at Miller Community Center on Monday, Dec. 9. Below are the PDF files that were shared at the event.

The Office of Arts & Culture (ARTS), in partnership with Seattle City Light and Seattle Parks and Recreation (SPR) is seeking an artist/artist team to develop an interior permanent site-specific artwork as part of a solar microgrid project at the Miller Community Center in Seattle’s Capitol Hill neighborhood. The artist(s) will meaningfully engage with the users of the Miller Community Center as part of the design process and work with City Light staff to gain a working knowledge of Seattle City Light’s sustainability goals.

This call is open to emerging and established artists residing in Washington, Oregon, Idaho. The deadline to submit an application is Wednesday, March 11, 2020 at 10:59 p.m. Pacific. To apply, please visit

What is the Microgrid Resiliency Project?

Seattle City Light is partnering with Seattle Parks and Recreation to implement a microgrid project at Miller Community Center, located in the Capitol Hill neighborhood. The project will include the installation of a battery energy storage system, solar panels and microgrid controls.

The microgrid will provide backup power storage for the community center during emergency events, such as a windstorm or unplanned power outage. When the electric grid is down, the microgrid will generate and provide power to the community center to keep the center's services and communications operational.

A $1.5 million grant from the state of Washington will provide a portion of the funds for the project. The City of Seattle is partnering with the University of Washington to perform analytics on the microgrid's community and utility benefits.

How will the project operate?

During normal operations, the solar panels will charge the batteries. When the solar panels are not generating, the batteries can back up the delivery of electricity from City Light's distribution grid. The microgrid will provide backup power storage for the community center during unplanned outages such as a windstorm.

What are the project's benefits?

The project will empower a community to recover quickly from unplanned emergency events and gain technical knowledge on the installation and operation of a microgrid system. Analytics from the microgrid resiliency project will allow the City of Seattle to research and develop similar technologies.

How will the project be funded?

In August 2016, Governor Jay Inslee announced $12.6 million in Clean Energy Fund grants to five utilities in the state of Washington. Seattle City Light's microgrid resiliency project was chosen as one of the recipients for a state clean energy grant from the Washington State Department of Commerce. A $1.5 million grant will provide a portion of the funds for the project. The additional $1.8 million in project costs will be funded by Seattle City Light.

Who did the City of Seattle select to work on the project?

The City of Seattle is working with several groups to learn how the microgrid will impact or benefit Seattle City Light's electrical system and customers. The project will allow the utility to gain valuable insights on what it takes to design, build and operate a microgrid. The findings from this project will also determine how Seattle Parks and Recreation and other city partners can incorporate innovative technologies like microgrids in their operations.

Owner's Engineer: DNV GL was hired for their microgrid expertise. They evaluated sites for the microgrid and will oversee the project through design, construction, commissioning and testing.

Analytics Team: The University of Washington will gather data and perform quantitative and qualitative analysis of the microgrid, community and system benefits.

Building Engineered Systems Contractor: Worley was selected to design, build, test and commission the microgrid.

What is the project schedule?

The design and construction for the new microgrid is now scheduled to occur in mid-2020. Analytics on the project will be completed after the microgrid has been installed.
