President William Ruto on Monday commissioned the fully energized 400\/220KV Mariakani sub-station- in Kilifi County, developed by the Kenya Electricity Transmission Company (KETRACO).<\/p>\n
The Mariakani Substation is the most strategic power substation in the Coast region and forms a critical gateway linking the Coast to Nairobi through the national transmission grid. The project significantly strengthens electricity transmission capacity while advancing the Government\u2019s Vision 2030 agenda of achieving 100pc renewable energy.<\/p>\n
For decades, the Coast region has heavily relied on expensive thermal generation to meet its electricity demand due to limited renewable energy generation within the region. Following the energization of the Mariakani Substation and associated transmission infrastructure in December 2025, thermal power generation at the Coast has reduced drastically from 100MW to 35MW representing a 65 percent reduction in reliance on fossil-fuel based energy.<\/p>\n
Originally developed as a 220kV facility, the Mariakani Substation has now been upgraded to 400kV, greatly improving power quality, reliability and transmission efficiency across the Coast region, while further enabling the region to draw more power from Olkaria and Suswa Substation, a major national and regional switching center. The enhanced capacity is expected to support rapid industrialization, investment growth and the expansion of Kenya\u2019s Blue Economy initiatives.<\/p>\n
Speaking during the commissioning ceremony, President Ruto reaffirmed the Government\u2019s commitment to accelerating Kenya\u2019s transition to clean and sustainable energy.<\/p>\n
\u201cMy Government is committed to adopting innovative, clean and sustainable energy technologies that will drive economic growth while protecting our environment. Projects such as the Mariakani Substation are critical in strengthening our national grid, expanding access to reliable electricity and advancing Kenya\u2019s vision of achieving 100 percent clean energy,\u201d said President Ruto.<\/p>\n
The substation forms part of the Nairobi\u2013Mombasa Transmission Line designed to carry more than 1,000MW of electricity between the two regions while easing pressure on the Coast\u2019s power network.<\/p>\n
The 400\/220kV Mariakani Substation is also a strategic component in strengthening Kenya\u2019s national transmission system and the broader East African regional interconnected power network. Reinforcing the national grid is critical in maximizing the operational benefits of the 500kV Ethiopia\u2013Kenya HVDC Interconnector and the 400kV Kenya\u2013Tanzania Interconnector.<\/p>\n
\u201cThe Mariakani transmission infrastructure has significantly reduced the Coast region\u2019s reliance on expensive diesel-powered electricity generation by enabling efficient transfer of power between Nairobi and Mombasa through the 400kV Mariakani\u2013Isinya double circuit transmission line. The project has also improved voltage stability and enhanced overall power quality across the region, resulting in a more reliable and efficient electricity supply for homes, businesses and industries,\u201d Said Eng. Kipkemoi Kibias, KETRACO Ag. Managing Director.<\/p>\n
Financing for the Mariakani Substation was provided through a partnership between the Government of Kenya and the African Development Bank (AfDB) at a total project cost of Ksh 4 billion.<\/p>\n
China CAMC Engineering Co. Ltd served as the project contractor under the supervision of KETRACO engineers,<\/p>\n
The commissioning of the fully energized Mariakani Substation further cements Kenya\u2019s position as a regional leader in clean energy transition, regional power integration and modern electricity transmission infrastructure.<\/p>\n
