With four cities down and four to go, Sonoma County officials this week enter the second half of their roadshow to convince cities to take part in the county’s planned public power agency.

Windsor on Wednesday became the first city to join the Sonoma Clean Power Authority, created as an alternative to PG&E to provide a greener product at competitive, if not cheaper rates.

Sonoma County supervisors were told Tuesday that they could have $24.4 million in property tax revenue available through mid-2017 to complete former county redevelopment projects and programs.

The Cloverdale City Council has said it’s premature to join a public power agency intended to supplant PG&E as the city’s primary source of electricity.
