Is 10-Baht per unit electricity for renting a commercial restaurant property overpriced?

[creative1000]

Commercial restaurant property inside a resort (right next to the lobby), employee says its 10-Baht per unit of electricity. They're also including 4 commercial AC units for free. Compared to my own house, I believe the electric rate is nearly double the price we pay per unit, but maybe this is the normal going electric rate when renting commercial properties, especially when co-located within a larger building with other businesses?

Location is Chiang Mai
