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.

Third District Supervisor Shirlee Zane aimed high at the Rohnert Park City Council on Tuesday, as the political campaign to convince cities to join the county’s public power agency continued.

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.

Plans for a public power agency and the renewable energy projects that could sprout with it appear to have scrambled politics in Sonoma County.

Sonoma County officials made their first pitch for a public power agency on Tuesday night to the Sebastopol City Council, with seven more stops to go in a campaign to enroll eight cities in a plan to supplant PG&E as their sole source of electricity.

Sonoma County supervisors hailed a landmark conservation deal Tuesday as they unanimously approved $4 million in open space dollars to help with the $24.5 million purchase of Preservation Ranch in the county’s northwest corner.

The Sonoma County Board of Supervisors Tuesday voted to implement a public power program for all homes and businesses outside city limits with plans to expand countywide.

Five months from now, Sonoma County intends to launch its program to become the power supplier to 220,000 local homes and businesses, displacing Pacific Gas and Electric Co. from its position of energy dominance.

Clearing the way for a landmark Sonoma County conservation deal, the state Coastal Conservancy board Thursday approved a $10 million contribution toward the purchase of Preservation Ranch, a 19,652-acre property that sprawls across the county’s northwest corner.

Sonoma County Supervisor Efren Carrillo has confirmed he is ‘seriously investigating’ a run for the state Assembly seat for the North Coast to be vacated next year by Wes Chesbro.

Carrillo would join two other local candidates, Jim Wood, the Healdsburg city councilman, and John Lowry, the former executive director of Burbank Housing in Santa Rosa, both of whom have said they are running for the Assembly seat. All three are Democrats.
