Community Solar - Current Projects
Seattle City Light's current project is in partnership with affordable housing provider Capitol Hill Housing. It has a limited number of units, so act now to help bring new, clean, renewable energy to our electric grid while benefitting both yourself and an organization that is dedicated to conservation, sustainability and community.
Seattle City Light has teamed up with affordable housing provider Capitol Hill Housing (CHH), for its fourth
Community Solar project. Capitol Hill Housing helps people of limited means to have a home by providing secure,
affordable apartments to more than 1,700 of our neighbors across the city. The system is on the roof of a
30-unit apartment building located in the heart of Capitol Hill. Although owned and managed by City Light
between now and June of 2020, this is also a key project of the Capitol Hill EcoDistrict
- a neighborhood-based sustainability initiative serving the most
densely populated urban village in the Pacific Northwest. When the project ends mid-2020, full ownership and
management of the system will be transferred to CHH and the energy generated will help reduce their operating
costs, which directly translates into benefits for CHH tenants.
Plan for 25 kW system at CHH's Holiday Apartments
Capitol Hill Project Details
- Single site project
- 25.92 kW
- Made-in Washington Itek modules & inverters
- A "ballasted" system on the flat roof of the Holiday Apartments, located at 1001 E. John Street
on Capitol Hill
- After system ownership passes to CHH, the electricity it generates will lower the operating
costs for the Holiday Apartments and other CHH properties, directly benefitting low-income tenants
- Live solar data can be seen here.
As with our previous Community Solar projects, the upfront costs will be paid by Seattle City Light, but ultimately the cost of the project will be paid for by customers who enroll in the program and participate by buying one or more solar units. These customers will in turn be paid back as they receive Washington State production incentives and City Light energy credit payments that currently total $1.16 per kilowatt hour of electricity generated by a community solar project. As City Light's rates rise (very slightly) over time, the total payment will also rise as that increased rate is reflected in your payment.
Beginning in July of 2020, ownership of the solar systems will transfer to their respective hosts, who will
enjoy the benefits of the electricity generated by the solar arrays - lower electric bills! - for the rest
of the life of the systems.
- Solar units cost $150; each represents a 28 watt piece of the system
- Customers can buy from 1 - 125 units
- Phinney Ridge Project 2671 units
- Capitol Hill EcoDistrict Project 925 units
- Current Washington state production incentives ($1.08/kWh) and bill credits for the energy
produced (about 7.5 cents/kWh) add up to $1.16 per kilowatt-hour of electricity.
- Online enrollment system available
- Charges are divided into 2 equal payments across 2 bills
- The Phinney Ridge Project is expected to generate more than 77,000 kilowatt-hours of electricity per
year. With each unit of the array sized at 28 watts and assuming 1050 kilowatt-hours of electricity
produced for each kilowatt in size of the system, each unit could generate about $34 annually in credits
- The Capitol Hill EcoDistrict Project is expected to generate more than 26,000 kilowatt hours of
electricity per year. Assuming 1040 kilowatt-hours of electricity produced for each kilowatt in size of the
system, each unit could generate more than $33.75 annually in credits.
