100 kVA ≈ 76 kVA here
Adama stands 2,732 m up — the highest of the 7 Ethiopia cities we cover, on high-highland ground. Thinner air means less oxygen per stroke, so 2,732 m costs 24.3% of rated output.
Practically: 100 kVA on the plate is about 76 kVA in Adama. Size from the plate and the set runs at its limit from day one, glazing bores and wet-stacking. At 2,732 m a turbocharged engine recovers most of that 24.3% and is usually worth the difference.
9.1 °C to 19.5 °C. A 10.4 °C cycle is enough to loosen connections within a year or two in Adama. The intermittent faults that follow get misread as controller trouble; they are almost always a terminal needing re-torquing.
Adama is roughly 1368 km north of our base at Embakasi, Nairobi, in a straight line and across a border. At 1368 km, mobilisation is a real line in any Adama quotation, and a machine waiting on a travelling part waits days, not hours. Hold a critical kit on site — filters, belts, an AVR, injectors — rather than ordering per failure.
Elevation: Open-Meteo Geocoding API (GeoNames elevation), retrieved 2026-08-26. Temperature: Open-Meteo Archive (ERA5 reanalysis), 2025 daily maxima and minima. Derate figures are planning estimates using standard corrections (approximately 1% per 100 m above 300 m; 2% per 5 °C above 25 °C); final sizing follows the engine manufacturer’s own derate tables for the set proposed.
We supply and install heavy-duty generators for factories, hospitals, and data centers in Adama.
