Listohan
there is nothing wrong with a good embedded network.
The strata buys electricity at a wholesale price. Each lot has a separate meter. Each lot is charged a retail rate. The strata pockets the difference, which ultimately goes back to the owners. You need a network manager to do the meter reading and billing.
Unfortunately many new buildings are sold with an embedded network manager thst does not advantage the strata. It’s akin to selling the building management rights on a long contract.
