SAN FRANCISCO (AP) — A group of San Francisco Bay Area cities, counties and water agencies has joined forces for what is being billed as one of the largest single government purchases of all-electric vehicles in the country.

The six cities, two counties and two water agencies have united to buy 90 electric vehicles with the help of a $2.8 million grant from the Metropolitan Transportation Commission, a regional transportation agency, officials with the Bay Area Climate Collaborative said Tuesday.
