This may have been asked before. What about adding a research option to allow power sharing between bases that are with close proximity of each other? Power grids exists in the real world.
Sorry if this is considered necro, but I may have an idea about power sharing between bases. It should cost more credits to send power of the same amount as tiberium/crystal. It should be like 8x as normally when you upgrade a unit, the ratio between tiberium/crystal with power should be 4 to 1.
