These Power Blocks are essential for powering your base—and with the updated EARN 22 service-station layouts, they expand seamlessly via EARN Service Trains.
Boiler Block
Boilers are your initial solution for base power needs.
Features:
Works with both coal and wood trains, prioritizing wood over coal.
Enable wood processing via the constant combinators to receive wood trains.
Performs best under full load when smart accumulator control is disabled.
Net Power Output: 475.2 MW
Components: 528 Boilers
Solar Block
Updated for EARN 22 with improved roboport positioning—adjacent solar blocks now share a unified logistics network without a bridge—and a better panel/accumulator ratio.
Solar Block with Service Station
Net Power Output: 145.38 MW
Components: 2,438 Solar Panels & 2,063 Accumulators
Ratio: 0.8462
Solar Block (No Service Station)
Net Power Output: 146.56 MW
Components: 2,456 Solar Panels & 2,076 Accumulators
Ratio: 0.8453
Fission Reactor Block
Reactor logic has been improved to take full advantage of the neighbor bonus when reactors are clustered. Water input still comes via fluid trains.
Features:
Enhanced reactor-neighbor bonus logic for higher per-reactor output.
Uses the EARN 22 Reactor Refuel Train from Service Hub → Trains with Refuel Station.
Stable Power Output: 2.4 GW
Peak Power Output: 2.584 GW
Components: 240 Heat Exchangers & 444 Steam Turbines
Efficiency: 375%
