Nestled on the scenic slopes of the Great Rift Valley, Naivasha has gone from being a beautiful lakeside destination to one of Africa’s leaders in terms of renewable energy production.
By harnessing geothermal energy produced by the volcanic forces beneath Hell’s Gate National Park, Naivasha now serves as the primary anchor of Kenya’s energy security, generating nearly half of the country’s total electricity. This new source of energy – derived from the Earth – is a reliable, continuous and clean energy source, allowing the further development of industries and the protection and preservation of the environment. Today, Naivasha is a model for other countries to follow, as it can produce energy for industrial activities without negatively impacting surrounding wildlife and support one of the country’s leading floriculture industries while protecting the national electricity grid from the effects of climate change.
How Naivasha became the geothermal capital of Kenya
Naivasha’s rise to its current status as the geothermal capital of the world began with the completion of the Olkaria 1 power plant in 1981; Kenya is therefore the first African country to harness geothermal steam from volcanic sources.
According to the study published on the International Renewable Energy Agency (IRENA) website, Naivasha’s location on the boundaries of the main tectonic plates gives Naivasha an advantage with regard to its thin continental crust and high temperature gradient. As a result, magma in the region heats aquifers to temperatures of more than 300 degrees Celsius.
This unique location therefore provides Naivasha with the capacity to produce approximately 900 MW of power from the Olkaria geothermal complex, representing approximately 47 percent of Kenya’s total electricity consumption.
The availability factor of geothermal energy (when compared to solar or wind energy) is about 95 percent, making Naivasha the most reliable energy center in East Africa for electricity generation.
Direct use of geothermal energy in Naivasha
The success of Naivasha’s geothermal energy can also be seen in off-grid ‘direct use’ applications. For example, Naivasha is the center of Kenya’s multi-billion-shilling flower industry.
According to the report titled “Sustainable Geothermal Energy Generation and Heating of Greenhouses and Spas in Kenya’s Rift Valley” published by the United Nations, geothermal steam is used to heat large greenhouses at a controlled ambient temperature, allowing year-round rose production and eliminating a significant amount of fungal diseases due to the ability to use less expensive energy sources, such as fossil fuels.
Furthermore, there is a 1,000-acre special economic zone in Naivasha, where manufacturers use subsidized geothermal energy at rates well below current market costs; For example, they can manufacture goods at a rate of about 7 US cents ($0.07) compared to current market rates of about 0.18 cents per kilowatt hour (kWh).
From sewage to a giant spa: Africa’s largest natural swimming pool
According to UNESCO, one of the main distinguishing features of Naivasha’s geothermal identity is the fact that it is located within Hell’s Gate National Park.
This requires advanced engineering techniques that reduce environmental impact. Large mammals such as giraffes and buffalo can be found roaming freely among the electricity production infrastructure due to the use of low-profile pipelines and silent turbines.In addition, the mineral-rich brine is used as a by-product of steam production to fill the Olkaria Geothermal Spa, the largest natural spa in Africa, significantly enhancing ecotourism revenues in the surrounding area.
The 5,000MW Dream: Supporting Kenya’s Vision 2030
In terms of technical achievements, Naivasha’s contribution to Kenya ranks sixth in the world for geothermal energy production from 2024 to 2026. According to the US Department of Commerce, the Government of Kenya has set an ambitious goal of adding up to an additional 5,000 megawatts of electricity generation capacity in Naivasha, under the Vision 2030 programme. The Geothermal Development Corporation (GDC), a state-owned company working to reduce the risks of drilling for private investors, will therefore contribute to making Naivasha a key driver in enabling Kenya to achieve the goal of a 100% renewable electricity grid.
