How much energy is produced by connecting a city to my capital

In Civ: Beyond Earth, the Civopedia tells me that roads cost 1 energy/tile/turn to maintain, but that connecting a city to my capital with a road will give me "a large amount of energy".

How much energy is this? What does the value depend upon?

Here is the equivalent question for Civ V. It is obviously not a duplicate, since it refers to a different game, but the mechanics may be similar.

Solution 1:

Routes appear to generate 1 energy per citizen in the non-capital city, plus some "base energy per route" amount. These amounts are directly added to your faction-wide income.

Check out the Economic Overview screen. Along the left side under Income will be a section that says "City Connections", you can expand that to see how much each connection is getting you.
