100 kVA ≈ 88 kVA here
Gisenyi stands 1,461 m up — the lowest of the 8 Rwanda cities we cover, on plateau ground. Thinner air means less oxygen per stroke, so 1,461 m costs 11.6% of rated output.
Practically: 100 kVA on the plate is about 88 kVA in Gisenyi. Size from the plate and the set runs at its limit from day one, glazing bores and wet-stacking. At 1,461 m a turbocharged engine recovers most of that 11.6% and is usually worth the difference.
16.9 °C to 22.9 °C is a narrow 6 °C cycle, so thermal movement will not age this installation. Steady warmth will: with nights only reaching 16.9 °C the batteries never cool, and sealed lead-acid life roughly halves per 10 °C sustained above 25 °C. Budget shorter replacement intervals in Gisenyi than the datasheet implies.
Gisenyi is roughly 853 km west of our base at Embakasi, Nairobi, in a straight line and across a border. At 853 km, mobilisation is a real line in any Gisenyi 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 Gisenyi.
