A STUDY ON THE TECHNICAL, ECONOMIC AND ENVIRONMENTAL FEASIBILITY OF THE WELLHEAD TECHNOLOGY IN POWER GENERATION IN KENYA

ABSTRACT:

This report summarizes our findings on the research topic of a study on the technical, economic and environmental feasibility study on application of wellhead technology in geothermal power generation in Kenya. The main objectives of the study were established whether geothermal wellhead technology is financially technically and environmental feasible for the purpose of power production in Kenya. This research was conducted through interviews, questionnaires, site visits and document reviews.

It was established that there were challenges with regards to the compliance with the local and international environmental regulation, efforts are however being put to ensure compliance in such areas. With regards to financial feasibility it was established that the technology is highly profitable, with significantly low initial investment and payback period compared to the central power plant. Early generation has further make this technology more attractive to the investors. Technical challenges encountered during the operation of wellhead generators include lack of an invocations lines leading to line trips, blockage of brine valves, clogging of valves, choking of the condenser cooling water and contamination of oil with water. However, regular maintenance has helped contained such challenges. These efforts have made this technology feasible financially, environmentally and technically.
