Well in coop multiplayer one player should be a regular merchant guild so that the other player as a megacorp can build branch offices and harness the trade value.
In singleplayer games if you can find a megacorp to join your trade league you can use the Golden rule succession to steal/reappropriate the energy he got from his branch offices on your planets. I managed to get an extra 25k+ energy every 10 years using this trick in the midgame. Just make sure you have a large energy surplus.
