Electricity Laws and Incentives in Washington

The list below contains summaries of all Washington laws and incentives related to electricity.

Laws and Regulations

Alternative Fuel Use Requirement

All state agencies must, to the extent practicable, use 100% biofuels or electricity to operate all publicly owned vehicles. Agencies must prioritize all-electric vehicles (EVs) when leasing or purchasing new vehicles, and all trips that may feasibly use EVs must employ them. For vehicle classes without EV model options, agencies must prioritize the most cost-efficient, low-emission vehicle option available. Agencies may substitute natural gas or propane for electricity or biofuel if the Washington State Department of Commerce (Department) determines that electricity and biofuel are not reasonably available. Practicability and measures of compliance are defined in rules adopted by the Department. The governor has established a cross-agency Governing Council, which must adopt and implement standards, measures, targets, and tools to support agencies in reducing greenhouse gas emissions and prioritizing EV adoption.

In addition, all local government agencies must, to the extent practicable, use 100% biofuels or electricity to operate all publicly owned vehicles. Transit agencies using compressed natural gas and engine retrofits that would void vehicle warranties are exempt from this requirement. To allow the motor vehicle fuel needs of state and local government to be satisfied by Washington-produced biofuels, the Washington Department of Enterprise Services and local governments may contract in advance and execute contracts with public or private producers and suppliers for the purchase of appropriate biofuels. Agencies may substitute natural gas or propane in vehicles if the Department determines that biofuels and electricity are not reasonably available. Practicability and measures of compliance are defined in rules adopted by the Department.
