Purpose
PSE's Community Solar program lets its electric customers buy into local solar without putting panels on their own property. PSE builds the arrays, divides them into shares, and credits subscribers on their bill for what their share actually produces. Renters, homeowners, and businesses can all take part, and PSE reserves a portion of every project at no cost for income-eligible customers, who are least likely to have a roof of their own to use.
The arrays sit on host properties across PSE's service area. Here, that is leased industrial roof space: the owner is paid to use the roof, and PSE funds, owns, and maintains the system. The connection is made on PSE's side of the meter, so the output goes to the grid and to subscribers rather than to the building underneath it.
Technical Details
Snowberry spans two roofs. Arrays on the two buildings aggregate into a single 800 A PV aggregation panel at 480/277 V, so two buildings deliver one point of interconnection rather than two. Unlike the Beargrass and Salal community solar sites, this Snowberry ties to an existing PSE transformer, which meant a new 600 A CT enclosure coordinated with PSE and a 600 A fused service disconnect rather than a new vault and a new pad. Communications equipment is fed from a dedicated service so the utility's monitoring stays up independently of anything on the host's side.
