@MaurantKilom - I don't mean changing the transferring within the grid - optimizing flows within the grid would be nightmarish if there were internal transfer caps. I don't mean a complicated peer-to-peer transfer cap.
I mean the grid itself works exactly the same as it currently does. A windgen can transfer 1000+ E to the next windgen. The cap is only hit when transferring power from a windgen to a mex. So the player still doesn't have to worry about the interior of the grid any more than he does now, he only has to worry about the power-points of the grid.
So, imagine we have a grid that looks like
SINGU -> WINDGEN -> FUSION -> 2 Mexes
The windgen doesn't matter. Even though the windgen's
output cap is 5, it has no cap
within the grid. The only cap that's relevant is the fusion. We've got about 260E in that grid, and 2 mexes to power. Under the old system, they'd each get 120E (assuming no other energy drains). Under my system, the power-cap on the fusion prevents them from recieving more than 50 each. So they each get 50 and the rest of the energy must go into the reserve. The fact that the windgen can only power 5E doesn't matter because the windgen is *internal*.
Now, if we had it
SINGU -> WINDGEN -> 2 Mexes
Then you'd be dealing with the Windgen's 5E power cap. Then you'd be putting the other 215ish energy into the reserve while the mexes get 5E each.
See? While it's more complicated than the current system (which, I'll grant you, is already pretty complicated) it's not
that bad. And the point is it will mean you have to invest near the mexes/superdefenses, not just building energy sources in back-country and running transfer stuff to the front.
Of course, you could take it a step further and remove the grid and just go by individual power-limits on energy buildings, but then we might basically end up back at square 1 with OD, effectively.
