They only need to RUN a single generator. A smaller, lighter backup generator could be fitted that is started in case the primary fails. While it is cycling up the batteries can take the load. It should still be a lighter system than having two or more full power engines.
The other option is to have enough battery capacity to allow flight to an emergency landing site (you don't need anything like full power for that).
