About COALCOM: Power Station
COALCOM: Power Station is a game about operating a coal-fired power station, played on a character-based terminal styled after a 1980s green-phosphor CRT and controlled from the keyboard. You are the new operator at Riverside Coal Power Station, with four hours of training, taking over after your predecessor tested whether the plant could run itself while he napped, and it could not. You keep boiler pressure (around 165 bar) and drum water level (between 40% and 60%) in range while handling coal feed and cooling, answer the grid operator's calls for more power and deal with breakdowns. The systems affect each other, so one change moves three other readings and faults cascade: there are 21 kinds of equipment fault, equipment wears down and you choose what to repair, and tripping the plant ends your shift. The campaign has ten shifts graded A to F, with controls unlocking over the first five; after Shift 5 a Continuous Mode of endless operation opens up. The store page says it is a game, not a realistic power plant simulator. In the Steam AI disclosure the solo developer, who says they have more than 20 years in the power industry, writes that generative AI was used to write and iterate on the game code, while the design, mechanics, domain expertise and voice are entirely human and the visual assets were not AI-generated. A paid game on Steam for Windows, released 11 May 2026, with a free demo covering shifts 1 to 4. English only.

How it was built
Partially verifiedThe developer's Steam AI disclosure says generative AI was used to write and iterate on the game code, and that this is what made it possible to finish a project idea more than ten years old. Some written content, including the store page copy and the game manual, was drafted with AI assistance and refined by the developer. The game design, mechanics, domain expertise and voice are described as entirely human, and the visual assets as not AI-generated. No tool or model is named, and no share of the code is given.
One developer with a background in the power industry supplied the design, mechanics and domain knowledge; per the Steam disclosure, generative AI wrote and iterated on the code, and the store copy and manual were drafted with AI help and then edited. The interface is a character-based terminal; the visuals are not AI-generated. After launch the developer shipped several patches, including a reworked Continuous Mode (Build 578).

“Generative AI was used to write and iterate on game code — it's what made finishing a +10-year project idea finally possible.”Verification notes: The AI claim rests on the developer-written AI disclosure on the game's Steam page (re-read on 4 Nov 2026), which says generative AI was used to write and iterate on the game code; it names no tool and gives no share, so the tool is undisclosed. The disclosure says the design and domain expertise are human, the store copy and manual were drafted with AI help, and the visuals were not AI-generated. Team size (solo) and the 20+ years in the power industry come from the same disclosure. Steam lists Pedro Matos as developer and publisher; the news posts are signed Mathus1978. Release date, price, Windows only, the demo app and English as the only language from the Steam store API; demo and launch details from the developer's Steam news posts; the review count from the store page on 4 Nov 2026. No AI content generated during play is described.
