Weather Matters: Protecting Your Generator Investment
Kenya's diverse climate zones present unique challenges for generator operation. From the humid coast to the dry north, from highland cold to equatorial heat, each region requires specific considerations.
Understanding your local conditions helps you maintain optimal performance and extend generator life.

Impact on Generators
Corrosion:
Salt and humidity accelerate corrosion of:
- Electrical connections
- Battery terminals
- Fuel tank
- Frame and enclosure
Moisture Problems:
- Water in fuel system

- Thorough fuel system service
Recommended Products:
- Marine-grade battery terminals
- Corrosion inhibitor spray (CRC, WD-40 Specialist)
- Desiccant in control panels
Highland Region: Nairobi, Nyeri, Kiambu, Nakuru, Eldoret (Uasin Gishu), Nyandarua
Climate Characteristics
- Altitude: 1,500-2,500+ meters
- Temperatures: 10-25°C
- Lower oxygen levels
- Cool nights, warm days
- Significant temperature swings
Impact on Generators
Altitude Derating:
| Location | Altitude | Power Loss |
|---|---|---|
| Nairobi | 1,795m | ~20% |
| Nakuru | 1,850m | ~21% |
| Eldoret | 2,100m | ~24% |
| Nyeri | 1,759m | ~20% |
A 100kVA generator in Nairobi effectively delivers ~80kVA.
Cold Starting:
- Difficult starts in early morning
- Increased battery drain
- Thicker oil causes drag
Condensation:
- Morning dew inside fuel tank
- Water in fuel system
- Moisture in electrical components
Highland Maintenance Requirements
Daily:
- Check for condensation in fuel tank
- Monitor oil viscosity (cold mornings)
- Verify battery charge
Seasonal (Cold Season):
- Consider block heater installation
- Use winter-grade oil (10W-30)
- Battery blanket for extreme cold areas
Recommended Solutions:
- Altitude compensation kit
- Block heater for cold starts
- Water-absorbing fuel filter
- Battery tender/maintainer
Northern Arid Region: Turkana, Marsabit, Garissa, Wajir, Mandera, Isiolo
Climate Characteristics
- Extreme heat (35-45°C)
- Very low humidity
- Minimal rainfall
- Fine dust/sand
- Strong winds
Impact on Generators
Overheating:
- Cooling system stress
- Reduced engine efficiency
- Faster oil degradation
Dust Contamination:
- Clogged air filters
- Radiator fin blockage
- Bearing contamination
Fuel Issues:
- Fuel evaporation
- Tank pressure buildup
- Quality degradation in storage
Arid Region Maintenance Requirements
Daily:
- Check coolant level
- Inspect air filter (may need cleaning)
- Monitor temperature gauges
Weekly:
- Clean or replace air filter
- Blow out radiator fins
- Check fan belt condition
Monthly:
- Change oil (heat degrades faster)
- Deep clean entire generator
- Fuel system inspection
Recommended Solutions:
- Heavy-duty air filtration
- Pre-filter installation
- Enhanced cooling package
- Fuel tank shade structure
- More frequent oil changes
Lake Region: Kisumu, Siaya, Homa Bay, Migori, Kisii, Nyamira
Climate Characteristics
- High humidity (65-75%)
- Temperatures: 20-30°C
- Significant rainfall
- Lake-effect weather
- Altitude: 1,100-1,500m
Impact on Generators
Humidity Effects:
- Electrical corrosion (less than coast)
- Fuel water contamination
- Rust development
Rainfall Considerations:
- Flooding risk
- Extended wet periods
- Drainage important
Lake Region Maintenance
Regular Focus:
- Water separator drainage
- Electrical connection inspection
- Proper drainage around generator
Rainy Season Preparation:
- Elevate generator if flooding possible
- Check enclosure seals
- Verify drainage is clear
Seasonal Considerations Across Kenya
Rainy Seasons (March-May, October-December)
All Regions:
- Drain water separator weekly
- Check fuel for water contamination
- Verify weatherproof enclosure integrity
- Ensure proper drainage
- Monitor electrical connections
Pre-Season Preparation:
- Service water separator
- Add fuel stabilizer
- Check enclosure seals
- Clear drainage channels
- Test emergency operation
Dry Season (January-March, July-September)
All Regions:
- Increased dust filtration needs
- Fire risk management
- Cooling system attention
- Fuel storage care
Specific Actions:
- More frequent air filter service
- Keep area clear of dry vegetation
- Monitor coolant levels closely
- Protect fuel from heat
