FLAGSHIP GAMEBuild the power station. Master the physics. Keep the lights on.
A top-down construction and management simulation built with uncompromising engineering credibility. From real IAPWS-IF97 steam thermodynamics and Brayton cycles to live wholesale electricity dispatch and PWR nuclear safety systems.
Decker Enterprises builds games that take real systems seriously and make them fun. Power Plant Architect is the studio's flagship, and right now its entire focus.
Like Prison Architect, you start with raw earth and an empty grid. Lay foundations, roads, heavy blast walls, and security doors, then position heavy boilers, turbines, and transformers before connecting high-pressure steam and cooling loops.
Underneath the graphics runs an authentic IAPWS-IF97 steam formulation. Condenser vacuum rises and falls with ambient cooling water temperatures; wet steam droplets physically erode turbine blades if your reheat cycle falls out of spec.
Balance firm supply contracts against a volatile hourly electricity market shaped by the solar duck curve. Manage rising carbon prices, bank loans, and maintenance crews. Spend three consecutive days in the red, and creditors step in.
Click any component on your plant floor to open a live thermodynamic inspector. Trace enthalpy, entropy, mass flow rates, and condenser vacuum in real time as your operational team responds to peak grid demand.
Every machine, pipe, valve, and wire serves a physical purpose. Experience a management simulation that rewards understanding the underlying science.
Lay foundations, heavy roads, structural walls, and security doors. Place boilers, steam turbines, generators, condensers, multi-stage pumps, feedwater heaters, cooling towers, and step-up transformers.
Route dedicated steam, feedwater, cooling-water, fuel, and high-voltage transmission lines. A full crew of builders, technicians, and operators brings your plant to life.
Built on rigorous IAPWS-IF97 steam tables. Model Rankine cycles with reheat and regenerative feedwater heating, alongside gas turbines (Brayton cycle) subject to ambient air derating.
Achieve combined-cycle efficiencies reaching ~55%. Condenser vacuum dynamically tracks cooling water temperatures, while wet steam droplets physically erode turbine blades if moisture exceeds threshold.
Operate a full Pressurised Water Reactor (PWR) thermal core with true decay heat simulation, neutron flux management, primary loop pressurizers, and emergency safety trains.
Execute emergency SCRAM shutdowns when temperatures drift out of safe envelopes, and rely on emergency diesel generators (EDGs) in the event of total loss of offsite power (LOOP).
Perform economic dispatch against an active wholesale electricity spot market. Capitalize on heat-wave price spikes while surviving mid-day solar 'duck curves' and escalating CO2 allowance prices.
Sign firm delivery contracts with regional grid operators. Manage debt amortization, fuel supply logistics, carbon emissions, and maintenance outages. Three days in the red and creditors take over.
Progress through an interconnected 15-node technology tree spanning regenerative feedwater heating, reheat stages, gas turbines, combined cycle systems, scrubbers, wind, battery storage, and advanced nuclear.
Earn 25 achievements and strive for a prestigious 5-star Plant Rating. Comply with evolving Clean Air Act environmental legislation by retrofitting FGD scrubbers or paying heavy penalties.
Engineered from the ground up for seamless cross-platform play. Run natively on Windows PCs, directly inside modern web browsers, or on Android phones and tablets.
Engineered with tailored touch controls supporting both portrait and landscape orientations, plus an official TikTok Mini Game currently in active development.
Real thermodynamic math. Every percentage point of thermal efficiency requires deliberate engineering design. These are actual test benchmarks from the game's simulation engine.
Single-stage expansion without regenerative heating. Baseline thermal efficiency.
Intermediate pressure reheat loop plus 5 bleeding-steam regenerative feedwater stages.
Gas turbine exhaust gases channeled into HRSG boiler powering secondary steam turbine.
Primary loop coolant under 15.5 MPa non-boiling water transferring heat to steam generator.
Burns fuel to convert pressurized demineralized feedwater into high-temperature superheated steam for turbine admission.
