SPOKANE, Wash. (AP) — The Spokane City Council may vote to override a mayoral veto of an ordinance that set goals for reaching 100 percent renewable energy for electricity by 2030.

KPBX-FM reports that Mayor David Condon cited concerns about electricity costs and potential liability in his veto letter Thursday.

The Council approved a measure on a 6-to-1 vote last month calling on the city to prepare a plan to run its operations exclusively on renewable electricity sources by 2020, with the rest of the city meeting that goal by 2030.

The Spokesman-Review reports the council will consider overriding the veto at a later meeting.

Councilmembers Ben Stuckart and Breean Beggs say the measure doesn't create additional costs for the city.

Beggs noted that the council revised the legislation to meet Condon's concerns and that changes were supported by the region's utility, Avista.
