KenGen has printed a young for consultancy providers to conduct a feasibility examine on energy era from separated geothermal brine.
Kenya’s state-owned electrical energy era firm KenGen has introduced a brand new tender for “Consultancy providers for feasibility examine on geothermal energy era brine in KenGen Olkaria Area.” The tender is open for worldwide candidates.
Expressions of Curiosity in English should be obtained on or earlier than 28 February 2024. The detailed tender doc will be accessed by way of this hyperlink.
Mission background
The principle goal of this feasibility examine is to evaluate the technical, financial, environmental, and monetary viability of energy era from brine and possible un-utilized wells throughout the Olkaria Geothermal subject.
In Olkaria geothermal subject, KenGen has drilled over 180 manufacturing wells. The wells produce two section geothermal fluid that’s separated into steam and brine. In whole, the manufacturing wells related to the present energy vegetation produce over 4,000 tonnes per hour of brine at separation pressures of between 6 and 12 bars and corresponding temperatures of between 158 °C and 188 °C. The separated brine from the interconnected wells is then re-injected whereas nonetheless at excessive temperatures (>160°C).
KenGen intends to make the most of this appreciable quantity of warmth power within the separated brine for added energy era utilizing binary expertise. As well as, there are a selection of manufacturing wells which were drilled however haven’t been utilised within the single flash condensing energy vegetation due to their low stress, lengthy distances to the present energy vegetation, low enthalpy, and cyclic traits of among the wells. A part of the scope of the examine shall contain analysis of those wells for potential use with the brine for energy era.
It’s in view of the above that KenGen needs to interact a marketing consultant to hold out an in depth examination and examine of the brine manufacturing from Olkaria fields, analyse the bodily high quality and amount of the brine for reinjection, suggest most beneficial wells for reinjection and advise on the extra energy era attainable from the brine by use of Binary expertise and additional advise on the potential chemical, technical and financial constraints plus choices.
The profitable candidates should have confirmed technical capabilities and a confirmed observe file in finishing up feasibility research and operation of binary energy vegetation. The examine is predicted to take 6 months.
KenGen is presently endeavor growth efforts within the Olkaria geothermal subject, primarily by the use of uprating of the generators of Olkaria I and IV geothermal energy vegetation. Work on the rehabilitation of the Olkaria I, the oldest geothermal energy plant in Kenya, began in mid-2023.
