The test fleet program has been in operation since 2003 and this is the second extension of the contract for Ballard. The extension is based on the success of the test program so far. The twelve buses in the two cities has exceeded expectations so far with some of the stacks having run for over 4,000 hours of service already. In service availability for the fuel cell buses averaged ninety-eight percent during 2006.
