Upon being built this power plant will run itself indefinitely, but to run efficiently this powerplant needs to be provided lava to the central tank. Whether the lava is provided by a creative tank, a train transporting lava, or an infinite lava pool does not matter, but those are not provided in this schematic. The schematic has two level 9 steam engines for a total of 294,912 stress units, but uses 1,536 stress units to run itself, so the net production is 293,376 su. This power plant is based on a previous design I did in a multiplayer server with friends, just shorter since I wanted to keep the resource cost low for anyone who wants to build this in survival.
