Not quite sure about it.
Yes, the energy cost per flight would probably be cheaper. I fully expect MX to be cheaper, as both electric engines and batteries are less complicated and easier to replace/upgrade.
However, the cost could come from investment cost. There was a calculation done many times here, how much fuel and MX is spent on plane. Will it offset higher purchase price? Over the time, probably. Will it be substantially cheaper? On operating costs, I tend to agree. On TCO, not so much.

This question has rattled around in my head as we get closer to having battery electric short haul aircraft. If the noise is extremely low, it makes me wonder if we'd see an increase in demand for inner city airports.
