If your KPLC bill jumped recently and you’re not sure why, there’s a genuine, specific reason — and it’s worth understanding, because it changes how “normal” usage months are priced, not just a one-off bad month.
What actually changed
In a gazette notice dated September 18, 2026, EPRA amended how Kenya Power classifies customers into domestic tariff bands. Under the new rule, your tariff category is now based on a rolling 3-month average of your consumption, rather than being fixed. Customers averaging up to 30 kWh a month over that rolling window fall into DC1, the lower-cost “lifeline” category. Cross above that average, and you move into DC2, the standard domestic category — at a meaningfully higher per-unit rate.
The part worth paying attention to: because it’s based on a 3-month average, a single unusually high-usage month — visitors staying, hotter weather pushing up fan or fridge use, a one-off appliance purchase — can pull your rolling average up enough to shift your whole tariff category, not just that one month’s bill. You could find yourself paying the higher DC2 rate for months afterward, even once your usage drops back to normal, simply because the average hasn’t caught back down yet.

Why this matters more than a typical tariff adjustment
Kenya’s electricity pricing has moved in several directions this year — a proposed base tariff hike of 14–31% was actually withdrawn by government in June 2026 after public pushback, and a small base-rate reduction was announced alongside that withdrawal. But separately from the base rate, monthly fuel energy cost charges and forex adjustment charges (reflecting the shilling’s movement and actual fuel costs used in generation) have continued to add to bills on a month-by-month basis — in some months adding several shillings per unit on their own.
Combine that background volatility with this new 3-month averaging rule, and the practical effect for a lot of households is: electricity costs have become genuinely harder to predict from month to month, in a way that a flat, fixed solar system cost simply isn’t.
What this means if you’re considering solar
This is exactly the kind of structural change that strengthens the case for solar, independent of any single month’s headline tariff number. A solar system — once paid off — produces electricity at a cost that doesn’t move with EPRA gazette notices, forex swings, or a 3-month rolling average catching up with one unusually busy month. For households already close to the DC1/DC2 threshold, even a partial solar offset that keeps your KPLC draw consistently low can matter for which tariff band you land in, on top of the direct savings from using less grid power overall.

What to do right now, regardless of whether you go solar
Pull your last 3–4 months of bills and check your actual kWh consumption, not just the shillings total — this tells you which band you’re likely sitting in under the new rule. If you’re hovering close to the 30 kWh threshold, small, deliberate reductions in usage (switching off appliances left on standby, shifting high-draw tasks to off-peak where relevant) can matter more now than they did before this rule took effect, since they affect your rolling average, not just a single bill.
