Pick a product line, pick your application, set the size — see how many ENERGIN units it takes, what heat you can recover, whether absorption cooling makes sense, and what a waste-gas fuel is worth. Units run from the smallest 115 kW-class to 500 kW-class blocks in limitless multiples, packaged your way — open skid, sound enclosure, 40 ft container, or container with sound enclosure (≈1 MW per container) — with factory turns of 12 weeks to 12 months by order size. Budgetary education for playing around — real sizing is a professional exercise. What's in the math ↓

This tool is for playing around. It runs on public rules of thumb; your actual demand must be measured and calculated by a professional — load study, metered interval data, gas analysis, site conditions. Tomris arranges exactly that with RSE factory engineering when you inquire. See what the numbers do and don't account for ↓
Play with this tool all you like — that is exactly what it is for. Every figure is a published rule of thumb for a typical facility: good enough for a first conversation, nothing more. Actual demand must be measured and calculated by a professional — twelve months of metered interval data, a load study, a fuel gas analysis, and site conditions. Tomris arranges that with RSE factory engineering as step one of any inquiry. Here is what each benchmark includes:
IT load × PUE 1.4 — cooling plant, UPS and distribution losses, lighting and offices ride on top of the servers. The profile is nearly flat (peak factor 1.05), and standby duty backs up 100%: data centers protect everything.
2.5 kW/bed is a whole-campus average that already contains the imaging suites (MRI, CT, X-ray), operating theatres, HVAC, medical air and vacuum, kitchens, laundry, and labs. Peak factor 1.5 covers morning imaging + HVAC coincidence; standby sizes to the ~60% code-critical share.
1.3 kW/room includes HVAC, kitchens, laundry, pools and spa, elevators, and common-area lighting — not just the guest room. Peaks hit at check-in and dinner service (factor 1.5); emergency covers ~35%: egress, cold rooms, kitchens, one elevator bank.
0.5 kW/student blends dorms, labs, dining, sports, and lecture halls across a day. Labs and arenas drive the 1.5 peak factor; essential share ~30% for life safety and research freezers.
Your connected load × 0.6 diversity — nameplate motors never all run at once — with a 1.4 factor restoring coincident starts. Furnaces, compressors, and process lines can break this benchmark in either direction: the clearest case on this list for a metered study.
350 kW/ha is dominated by supplemental lighting, plus circulation fans, irrigation pumps, and screen motors. Lit hours shape the profile; CO₂ fertilization from engine exhaust is a bonus, not a load.
0.45 kW/home covers the electrical side only. Real CHP sizing here is heat-led — the heat load duration curve, not an electrical slider, chooses the machine. Treat this one as illustrative.
1 kWe per 500 population is digester-gas generation potential. The plant's own blowers and pumps then consume much of that power on site, and H₂S gas cleaning is mandatory before the engine — both are part of real design, not this slider.
1 kWe per 9 cows is manure-digester potential — not the farm's demand. Milking robots, milk chilling, ventilation, and automation draw their own power around the clock, and co-substrates (feed waste) can lift gas yield well above this number. Generation and demand must be balanced by an engineer.
4 kWe per Nm³/h of collected methane assumes cleaned, dry gas — siloxane and moisture treatment come first, and collection efficiency changes over the life of the site.
4.9 kWe per MSCFD nets out an allowance for the conditioning skid — separation, filtration, and compression all draw parasitic power — and rich, wet associated gas can derate an engine below its pipeline-gas rating.
42 kWe per tonne/day already deducts gasifier cold-gas efficiency and the cleaning train — cyclones, scrubbers, and filters that must tame tars before syngas may touch a combustion engine. Low heating value further derates output versus natural gas. The hardest fuel here: treat this number as the roughest of all.
Altitude and ambient-temperature derating; power factor and kVA versus kW; large-motor starting inrush; harmonics from VFDs and UPS gear; utility interconnection and local code limits; gas pressure, quality, and variability; future expansion; and your actual metered load profile. This is why the tool is for playing around — a professional load study and RSE factory sizing replace every assumption above at inquiry.
The tool sizes like an engineer: fill with 500 kW blocks, then finish with one trim unit closest to the remainder — a 1,238 kW target becomes 2 × 500 + 1 × 250, never eleven small machines. Because odd-sized demand doesn't divide evenly into fixed blocks, the plant lands slightly oversized on purpose: a touch long just loafs at high efficiency, while undersized browns out on the worst day. Oversize beats undersize — with one exception, peak shaving, where we round DOWN because an oversized peak-shaver is idle capital and the grid already owns the top of the curve. Waste-gas plants also round down, to what the fuel can actually feed. The dashed genset is the optional N+1 service spare: it exists so maintenance never means shutdown — untick the box and it disappears.
