The Iceland Geothermal Conference, IGC2016, will be held at the Harpa Conference Centre in Reykjavík, from 26th to 29th of April. The focus is on the advantages of utilising geothermal energy and how they will benefit us. The event is hosted by the Iceland Geothermal Cluster Initiative and is both conference and an exhibition.
As one of the sponsors ÍSOR will participate in the conference as well as the exhibition, be welcome to visit us at the booth no H-2.
Guðni Axelsson, Director Geothermal Training, will give a presentation on Development and utilization of the Olkaria geothermal system in Kenya.
Wednesday, April 27th at 12.10 to 12.30, Session 1, Room: Silfurberg.
Geothermal activity is widespread in the East African Rift in Kenya with 14 major geothermal prospects identified. Of these the Olkaria geothermal resource, which is about 120 km from Nairobi, has been most extensively explored and developed. Exploration of the Olkaria geothermal resource started in 1956, with deep drilling commencing in 1973 and the first power generation unit (15 MWe) was commissioned in 1981. Five power plants are currently operating in the field; Olkaria I with 45 MWe capacity, an expansion of Olkaria I with 140 MWe capacity, Olkaria II with 105 MWe capacity, Olkaria III with 115 MWe capacity and Olkaria IV with 140 MWe capacity. Olkaria I, including the expansion, Olkaria II and Olkaria IV are operated by KenGen while Olkaria III is operated by OrPower4 Inc. The latest power plants, Olkaria IV and the Olkaria I expansion, were commissioned in 2014 and early 2015. In addition KenGen is currently operating several well-head units at a combined capacity of about 30 MWe and the geothermal resources of the NW part of the area are utilized both for direct heat and small scale electricity generation by the Oserian flower farm. The total electrical generation capacity is, therefore, 575 MWe, while considerable untapped resources are believed to still exist in the area. An Icelandic consortium consisting of Iceland GeoSurvey (ÍSOR) and the engineering firms Vatnaskil, Verkís and Mannvit have been involved in two major projects regarding the Olkaria geothermal resource for KenGen since 2011; an optimization study concerning increased utilization and a model maintenance and training project. The objectives of the optimization study were to assess the energy production potential of geothermal resources within KenGen’s concession area in Olkaria, mainly through comprehensive reservoir modelling, to assess the feasibility of continued and increased production, as well as to propose an optimized development plan for the resource. The model maintenance project constitutes a continuation of the optimization study and aims at updating and revising the conceptual geological model as well as the numerical reservoir model of the Olkaria geothermal system on basis of new data, reassessing the production capacity of the Olkaria resource and training of KenGen scientific staff in conceptual and numerical model development.
Guðni Axelsson, Ph.D. is Director Geothermal Training at ÍSOR and Adjunct professor in geothermal science at the University of Iceland. Mr.Axelsson specializes in geothermal reservoir physics, including testing, monitoring and modelling of geothermal reservoirs, as well having long experience in geothermal resource management, including reinjection, tracer testing and sustainable utilization. He has e.g. worked on geothermal projects in Iceland, China, The Philippines, Kenya, Central-America and Europe. Guðni has been involved in world-wide geothermal training and technology transfer for 25 years, in particular through the United Nations University Geothermal Training Programme. He is first author of more than 50 international publications, co-author of numerous others as well as author or co-author of more than 250 reports.
