Hey Pappus, I did some digging and some maths (that's been a while) and it uses the following things to come to the 150:
- HQ/Core Structure: +10
- Workers (8): +96
- Derelict Power Plant: +5 (Flat Gain)
- Derelict Power Plant: +10 (Exploitation Gain)
- Energy Exploitation Level 5: +30 (This is the flat bonus, the second entry is the % bonus and doesn't count to generation)
