Nairobi: Geothermal Development Company (GDC) has achieved a significant breakthrough by successfully tapping into a viable steam source at the Silali field, part of the Baringo-Silali-Paka Geothermal project, which will generate 22 megawatts of electricity. This development marks a crucial step forward in the pursuit of expanding Kenya's renewable energy capabilities.
According to Kenya News Agency, the Silali field is one of three key areas-alongside Korosi and Paka-within the Baringo-Silali-Paka Geothermal project, where GDC has been actively drilling for the past seven years. Paul Ngugi, Managing Director and CEO of GDC, emphasized the project's initial phase aims to develop 300 megawatts across the three fields, with each contributing 100 megawatts.
Ngugi highlighted the significance of the recent success at Silali, comparing the output of one well at 22 megawatts to drilling roughly four wells, each yielding 5 megawatts. This efficiency is expected to result in substantial cost savings, considering the high expense of drilling individual wells.
The project at Baringo-Silali-Paka is a vital part of Kenya's strategy to diversify its energy sources. The geothermal resources in Kenya are estimated to have a potential capacity of 10,000 megawatts, with the country currently exploiting around 950 megawatts. GDC has already harnessed 75 megawatts of steam at Baringo-Silali-Paka and aims to develop a 105 megawatt power plant at Paka by 2027.
Ngugi also noted the progress at the Menengai Geothermal Project, where local firm Sosian Energy has launched a 35 megawatt power plant. Additionally, GDC plans to introduce an extra 1,065 megawatts into the national grid over the next decade, sourced from Menengai, Baringo-Silali, and the South Rift region.
GDC's innovative approach includes the exploration of wellhead technology, which allows for the rapid deployment of smaller power plants directly at the wellhead. This technology not only accelerates power generation but also maximizes the use of investments in drilling.
The Baringo-Silali-Paka project is set to play a pivotal role in boosting GDC's revenues and enhancing Kenya's energy independence. As the country seeks to transition from reliance on hydro and thermal power, geothermal energy is poised to become a cornerstone of Kenya's sustainable energy future.
