Looks like Gillig has electric buses on the street in Walnut Creek, California. Its the Central Contra Costa Transit Authority.
There is a cool video here: http://www.baesystems.com/en/article/zero-emission-buses-in-service-at-walnut-creek
They beat BYD in getting inductive charging (wireless) into operation!
The four buses are powered by BAE Systems’ electric propulsion and accessory systems.
