Peak Demand

A minimalist strategy game about keeping a growing city powered.

In development · PlaytestingComing first to Windows and macOS. Android and iOS planned.

Peak Demand key art: the title crosses from a light daytime city into a dark city lit by amber power lines.

Design a resilient power grid for a city that never stops growing. Lay cables between plants, substations and districts, route around rivers, and connect each new neighbourhood before its patience runs out.

Six campaign cities introduce new terrain and new sources of power — from coal and clean air to hydro reservoirs, geothermal fields and nuclear energy. Or take an endless city through ever-harder peaks, failures and forecasts.

Gameplay

  • Build with limited cable, two line capacities, sockets and river crossings.
  • Balance gas, coal, solar, wind, hydro, geothermal, nuclear and batteries as demand changes through the day.
  • Watch overloaded lines trip and reroute their load before a failure cascades across the network.
  • Plan around construction time, heat waves, storms and plant maintenance.
  • Choose one of three deliveries each morning, then prepare for the evening peak.
  • Play six campaign cities or an endless city with optional modifiers.

Screenshots

  • A morning in Peak Demand: amber power lines connect a gas plant and substations to residential, commercial and industrial districts beside a river.
  • An evening overload in Peak Demand: one cable glows red while warning pins mark districts that are running out of power.
  • Highland Dam on day five, with a hydro plant selected beside its river reservoir and a broad power network crossing the countryside.
  • Windward Isles divided by branching rivers, with pylons carrying power between islands and a forecast warning of an evening shortage.
  • Hot Springs on day five, where geothermal plants feed the grid while maintenance temporarily cuts power to part of the city.
  • A dense Atom Valley grid with a selected nuclear plant, hospitals, data centres and a mix of live and idle transmission lines.
  • A sprawling endless-mode city at night, its dense network of amber and orange power lines stretching across both banks of a river.
