The Olkaria Area is a region located immediately to the south of Lake Naivasha in the Great Rift Valley of Kenya, Africa.

[2] This is almost double the maximum daily electricity peak demand recorded in 2008/2009 for the entire country.

[3] The geothermal complex and power plants lie within the Hell's Gate National Park.

[6] The largest structure is Olkaria Hill, 2 kilometres (1.2 mi) across and 340 metres (1,120 ft) high.

[7] The oldest exposed sequence is the Ol Njorowa pantellerite formation of pyroclastic rocks, lava flows, and plugs.

However, the absence of tritium in the steam shows that the water is taking at least fifty years to travel from the lake, if that is indeed the source.

Production wells were drilled and commercial generation of electricity started in July 1981 with a plant built by Mitsubishi Heavy Industries containing a 15 MW turbo-generator.

[2] A third power station with 48 MW capacity, Olkaria III, is privately owned by a subsidiary of Ormat Technologies.

[14] The project will probably qualify for carbon credits under the Kyoto Protocol's Clean Development Mechanism.
