SerGanton the quote from Maxis about drained power supplies shortly after placing the Turbine seems to not matter. The quote always triggers on solo soon after placing the Turbine under the tower regardless of if you’re using the solo mod or not. You can see in this video of a solo Maxis speedrun that Maxis says the power supplies drained quote shortly after placing the Turbine, but the mod works as intended as seen by the step getting completed once the Avogadro is killed with an EMP Grenade under the tower while the Turbine is active, indicated by Maxis’ quote: “You have done well, but yet we need more energy.”
I suggest that you watch the Turbine before killing the Avogadro with an EMP. If it starts not emitting power, then you might fail and have to redo the step if you kill the Avogadro while having that low-power Turbine under the tower. Otherwise, once you kill the Avogadro with an EMP while there’s a Turbine under the tower, either listen to Maxis’ quote regarding having done well, or try completing the last step.
Update (2025/01/22):
Additionally, you’ll want to allow up to 6 seconds between placing the first Turbine and killing the Avogadro. I found out about this in October of last year and mentioned it in one of the topics I’ve posted.
