Power production - Factorio Wiki

Steam engine power. Each steam engine needs 0.5 boilers when running at full capacity. One offshore pump can supply 20 boilers and 40 steam engines.. The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at efficiency. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2
