Large Power Generator
Ancient Technology around levels 49-50, commonly cited at four Ancient points. Soften that unlock band if your tree differs; the job is the same either way: far more generation and storage than a basic Power Generator.
Build cost is Pal Metal Ingot ×200 and Electric Organ ×200. Workload sits near 5,000. That's a serious organ farm and an Electric Furnace already humming before you place one, so treat the Large as a late grid project, not a casual swap.
Introduced in 0.3.1 and buffed in 0.3.4, it became the practical answer for power-hungry farms. Mass Oil Extractor rows, multi-furnace smelting, and stacked assembly lines chew through a basic tank; this is the upgrade that keeps them online.
Pair it with an Accumulator for overflow the same way you did early game. Keep Generating Electricity pals assigned, and don't drop every extractor until the Large (or several) can actually refill under load.
