Installing a commercial generator involves more than just placing the unit and connecting a cable. It calls for correct sizing, a proper changeover switch setup, wiring to the distribution board, and often a concrete or steel base to keep the unit stable and safe. Below is a breakdown of typical costs involved.
| Service | Estimated Cost Range (KES) |
|---|---|
| Site assessment & load calculation | 3,000 – 8,000 |
| Generator base/foundation preparation | 15,000 – 50,000 |
| Automatic Transfer Switch (ATS) installation | 20,000 – 60,000 |
| Wiring & connection to distribution board | 15,000 – 40,000 |
| Exhaust & ventilation setup | 10,000 – 30,000 |
| Fuel line/tank installation | 10,000 – 35,000 |
| Full installation (small generator, up to 20kVA) | 40,000 – 90,000 |
| Full installation (large generator, 50kVA and above) | 100,000 – 300,000+ |
Costs vary widely depending on generator size, whether the ATS is included, and how far the unit sits from the main switchboard. Larger commercial and industrial installations typically need a certified electrician’s sign-off, which is worth factoring into your budget and timeline.
