EARN 22 Power Blocks

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%
