For funsies, I calculated the amount of power you need. Essentially, you should have consumption take less than 0.54 (~55%) of your peak, give or take. This means you need around ~1.85 more production than your consumption.
Please note, it does not seem like the consumption number doesn't account for build energy, consumed over the course of building similarly to matter. Perhaps you tried to build something that was a bit too expensive (or drones... drones take a lot of energy for upkeep).
When you're out in space, it seems like you can get away with consumption and production being equal.
