SB 5445 Washington Senate · 2025-2026 Regular Session

Encouraging utility investment in local energy resilience.

SB 5445 encourages utility investment in local energy resilience throughout Washington State. The bill defines specific "distributed energy priorities," including solar energy on landfills or existing structures, agrivoltaic facilities, and small-scale wind energy. It provides greater incentives for electric utilities under the Energy Independence Act when they invest in these designated priority projects. The legislation also streamlines the development of certain small-scale solar energy generation projects by exempting them from some environmental review requirements. This aims to promote the development of decentralized energy sources, affecting utilities, clean energy developers, and local communities.

MODERATE
This bill was amended to broaden the definition of 'distributed energy priorities' to explicitly include microgrids and electric utility infrastructure sites, allowing for more flexible solar and wind project locations. It also updated tax exemptions to cover small solar arrays on previously developed lands like driveways and patios, provided they are not on agricultural or timber land. Finally, the bill increased financial incentives for utilities, allowing them to count certain new distributed energy projects at four times their electrical output instead of double.
Scope change
The bill's scope expanded to include microgrids and utility infrastructure sites as eligible project locations, and it clarified eligibility for small-scale solar installations on non-agricultural developed lands.
ELIGIBILITY

Added 'microgrids' and 'electric utility infrastructure sites' to the list of eligible locations for distributed energy projects.

Expanded the definition of 'agrivoltaic facility' to remove the requirement that the land must also provide ecological value or habitat.

Created a new exemption for small solar arrays (under 1,000 sq ft) placed on previously disturbed lands like driveways and patios, excluding agricultural and timber lands.

FISCAL

Increased the incentive multiplier for qualifying distributed energy priority projects from double to four times the facility's electrical output for projects starting after the effective date through 2029.

DEFINITION

Updated the definition of 'demand response' to explicitly include energy storage that helps reduce system peak demand.

REQUIREMENT

Changed the calculation method for 'accelerated conservation' to measure savings based on the number of years the measure operates until 2030, rather than its projected useful life.
