Energy Efficiency and Capacity Milestones
Exact achievement milestones plus a concise energy troubleshooting checklist.

Table of contents
Energy efficiency and energy capacity are different targets. Efficiency measures how effectively the grid uses or produces energy; capacity measures how much energy it can hold. The achievement inventory provides five exact milestones for each.
Efficiency milestones
| Tier | Required efficiency |
|---|---|
| ENERGY EFFICIENCY I | 100% |
| ENERGY EFFICIENCY II | 150% |
| ENERGY EFFICIENCY III | 200% |
| ENERGY EFFICIENCY IV | 250% |
| ENERGY EFFICIENCY V | 300% or more |
Capacity milestones
| Tier | Required capacity |
|---|---|
| ENERGY CAPACITY I | 50,000 |
| ENERGY CAPACITY II | 200,000 |
| ENERGY CAPACITY III | 1,000,000 |
| ENERGY CAPACITY IV | 10,000,000 |
| ENERGY CAPACITY V | 50,000,000 |
Diagnose the live grid
The Status and energy readouts matter more than the next achievement label.

If current energy is falling:
- disconnect or idle one active consumer;
- watch whether the per-second rate recovers;
- verify that a generator has fuel and a valid grid connection;
- check that storage is not preventing production;
- add the consumer back only after the baseline is stable.
Harvesters, Salvagers, and Refiners can consume no energy while idle and draw energy only while working. Test a full work cycle instead of trusting an idle snapshot.
