Country Update: Direct-use of geothermal energy has not grown significantly since 2010 and greenhouse heating remains the leader with 50 ha heated for growing roses that are air-freighted daily to Europe and other world-wide locations. The installed capacity for these greenhouses is estimated at 16 MWt and annual energy use of 126.62 TJ/yr. Heat is only required normally from around 2:00 AM to 7:00 AM, but the heat also provides a dry environment that limits fungus growth. In addition pyrethrum drying is still being carried out at a plant constructed in the 1920s near Ebburu estimated at 1.0 MWt and 10 TJ/yr. At the Olkaria II power plant, the waste water is being piped to a swimming pool, locally referred to as “the blue lagoon”, estimated at 5 MWt and 40 TJ/yr. Changing rooms have also been built on site. The Lake Bororia Spa Resort has a pool at 0.4 MW and 6 TJ/yr. (Omenda and Simiyu, 2015).

Oserian Development Company Ltd (ODLC) constructed a 2.0 MWe binary plant in Olkaria Central to utilize fluid from a well leased from KenGen. The plant which will provide electrical power for the farm’s operation, was commissioned in July, 2004. ODLC, who grow cut flowers for export, is also utilizing steam from a 1.28 MWe well to heat fresh water through heat exchangers, enrich CO2 levels and to fumigate the soils. The heated fresh water is then circulated through greenhouses. The advantage of using geothermal energy for heating is that it results in drastic reduction in operating costs. The capacity of the geothermal use is 16 MWt and the annual energy use is 126.624 TJ/yr.
