If you'd want the transmission charges to match the cost to the utility you should have a base charge consisting of basically the cost to the utility of maintaining your customer relationship after the initial hookup cost, and another part to match the utility O&M cost of the grid distributed over all the customers. Then on top of that a time-varying per-kWh charge for the electricity transferred. This would probably in most cases be pretty cheap, except when the grid (either the utility grid as a whole or the local part that you're connected to) starts to become overloaded; in that case scarcity pricing would apply which would presumably be very high. This would incite customers to reduce usage during scarcity, or give the utility funds to invest in grid expansion.
Similarly for the energy price, that should match the wholesale price. Though see the $10k bills some people on a wholesale price plan got during last year's Texas freeze for why such an idea might not be so popular in practice, theoretically beautiful as it may be.
