Why you could start paying less for electricity

Kenyan electricity consumers may see relief on their monthly bills in the coming months after the Kenya Electricity Generating Company reported significantly improved water storage levels at the country's principal hydroelectric reservoirs, raising the prospect of reduced generation costs that could feed through to lower retail tariffs.

KenGen, which accounts for the bulk of Kenya's installed electricity generation capacity, indicated that reservoirs feeding key facilities including the Seven Forks cascade on the Tana River — comprising Masinga, Kamburu, Gitaru, Kindaruma, and Kiambere dams — are holding at levels that support sustained hydro output. The Seven Forks system alone contributes a substantial share of Kenya's dispatchable renewable generation.

Hydroelectric power is among the cheapest sources of electricity in Kenya's generation mix, and when hydro output is high, the national grid relies less on expensive thermal plants running on heavy fuel oil and diesel, which carry significantly higher per-unit generation costs. The Kenya Electricity Transmission Company manages dispatch decisions based on the available mix, and a hydro-heavy dispatch profile directly lowers the aggregate cost of power delivered to consumers.

Retail electricity tariffs in Kenya are set by EPRA and include a fuel energy cost component that fluctuates monthly. During periods of low reservoir levels — such as prolonged droughts that have affected the country with increasing frequency in recent years — fuel-dependent thermal generation rises, and this cost is passed on to consumers through tariff adjustments.

Kenya has invested heavily in geothermal capacity at Olkaria in the Rift Valley, which provides a stable baseload and reduces dependence on both hydro variability and costly imports. Analysts say a combination of healthy hydro levels and continued geothermal output could produce measurable tariff reductions if conditions hold through the dry season.
