Offshore wind promises much for Kenya—if the fish can cope
By Staff Writer
Kenya’s coastline stretches 536 kilometres along the Indian Ocean, yet the country has barely glanced at what lies beyond the surf. Whilst landlocked Ethiopia races ahead with ambitious renewable energy schemes and South Africa contemplates its coal-dependent future, Kenya stands on the cusp of an energy revolution that could transform the region’s power landscape. Offshore wind technology, already generating 75 gigawatts globally according to the Global Wind Energy Council, represents an untapped frontier for a nation that has built its green credentials on geothermal steam and solar panels.
The technology itself is deceptively straightforward. Turbines mounted on fixed foundations or floating platforms capture kinetic energy from ocean winds, converting it into electricity through generators housed within their nacelles. Unlike their onshore cousins, offshore turbines benefit from stronger, more consistent winds unimpeded by terrain. The Hornsea Project One in the North Sea, the world’s largest offshore wind farm, demonstrates the scale possible: its 174 turbines generate 1.2 gigawatts, enough to power one million homes.
Yet for Kenya, the question is not whether the technology works, but whether it can work here. The Indian Ocean presents both opportunity and challenge, with wind patterns shaped by monsoons and a seabed that plunges to depths exceeding 3,000 metres within 50 kilometres of shore. This geographical reality demands floating turbine systems rather than fixed foundations, adding layers of complexity and cost that could make or break commercial viability.
Mapping the invisible resource
Kenya’s wind resource remains inadequately mapped, a fact that troubles both potential investors and energy planners. The National Oceanic and Atmospheric Administration’s data suggests average wind speeds of 7 to 9 metres per second along Kenya’s coast, considered marginal for commercial offshore development. By comparison, the North Sea averages 10 to 11 metres per second, whilst Taiwan’s offshore sites clock 12 metres per second.
However, preliminary studies by the International Renewable Energy Agency indicate that Kenya’s northern coast, particularly near Lamu, experiences higher sustained winds during the southwest monsoon season from May to October. This seasonal variation could complement Kenya’s existing geothermal baseload, which currently provides 863 megawatts or roughly 40 per cent of installed capacity, according to Kenya Power’s 2024 statistics.
The Lake Turkana Wind Power project, operational since 2019, offers instructive lessons. Its 365 turbines generate 310 megawatts, making it Africa’s largest wind installation. The project took nearly a decade from conception to completion and required a dedicated 428-kilometre transmission line costing $300 million. George Gikonyo, who served as head of renewable energy at the Ministry of Energy until 2023, observed in a Nairobi briefing that “transmission infrastructure remains our Achilles heel. Offshore wind would face similar challenges, but with the added complexity of submarine cables.”
Kenya’s proximity to the equator presents another consideration. Tropical cyclones rarely form within 5 degrees of the equator, sparing the coast from the devastating hurricanes that plague Caribbean and Asian offshore installations. This reduces insurance costs and structural requirements, potentially offsetting other disadvantages. Yet the Indian Ocean’s deep waters necessitate floating platforms, technology still in its commercial infancy. Norway’s Hywind Scotland, the world’s first floating wind farm, achieved a capacity factor of 54 per cent in 2020, but at costs substantially higher than fixed-bottom installations.
Capital constraints and regulatory fog
The financial mathematics of offshore wind in Kenya defy easy optimism. Floating offshore wind costs between $3,500 and $4,500 per kilowatt to install, according to the International Energy Agency’s 2024 offshore wind outlook. A modest 500-megawatt project would require investment of up to $2.25 billion, roughly equivalent to Kenya’s entire education budget for 2024.
For context, Kenya’s geothermal plants cost approximately $4,000 per kilowatt, but deliver capacity factors exceeding 90 per cent compared to wind’s 40 to 50 per cent. The arithmetic becomes more favourable when considering declining technology costs. The Global Wind Energy Council reports that offshore wind costs fell 32 per cent between 2019 and 2023, driven by larger turbines and improved installation techniques.
Kenya’s regulatory environment adds further uncertainty. The Energy Act of 2019 provides a framework for renewable energy development but contains minimal provisions specific to offshore installations. Maritime jurisdiction, environmental assessment protocols, and grid connection standards remain ambiguous. “We’re essentially writing the rulebook as we go,” admits a senior official at the Energy and Petroleum Regulatory Authority who requested anonymity.
This regulatory vacuum contrasts sharply with established markets. Britain’s Crown Estate manages seabed leasing through structured auction rounds, whilst Denmark’s Energy Agency provides clear guidelines on environmental assessment and grid connection. Kenya lacks equivalent institutional capacity, a gap that will deter risk-averse international investors accustomed to regulatory certainty.
The country’s power purchase agreement structure presents another obstacle. Kenya Power, the national distributor, operates under take-or-pay contracts that have left it with expensive overcapacity. Installing additional generation, even if cheaper in the long term, exacerbates short-term financial strain. The utility reported losses of 3.3 billion shillings ($25 million) in the financial year ending June 2023.
When turbines meet turtles
The environmental calculus of offshore wind extends beyond carbon accounting. Kenya’s coastal waters support critical ecosystems: coral reefs that buffer shorelines, seagrass meadows that sequester carbon, and migratory routes for whales, dolphins, and five species of endangered sea turtles. The Kiunga Marine National Reserve, established in 1979, protects 250 square kilometres of pristine coastline near the Somali border.
Research from Europe’s offshore wind sector provides sobering lessons. A 2022 study in the Journal of Applied Ecology found that collision mortality affects seabirds, with Northern gannets and kittiwakes particularly vulnerable. Underwater noise during pile-driving operations can disrupt marine mammal communication over distances exceeding 100 kilometres, according to research published in Marine Pollution Bulletin.
Kenya’s situation differs in important respects. Floating turbines eliminate pile-driving, reducing acoustic trauma. The country’s coastline lacks the vast seabird colonies of the North Sea, potentially lowering avian collision risks. Yet knowledge gaps remain vast. “We don’t have baseline data on marine mammal populations or migration patterns,” explains Dr Judith Nyunja, a marine biologist at the Kenya Marine and Fisheries Research Institute. “Without that foundation, impact assessment becomes guesswork.”
The artisanal fishing sector adds human dimensions to environmental concerns. Over 30,000 Kenyan households depend directly on fishing, with many more involved in processing and trade. Offshore wind farms could restrict fishing grounds whilst potentially creating artificial reef habitats around turbine foundations. Experience from the Netherlands suggests coexistence is possible: the Borssele wind farm designates zones for fishing within the array, though tensions persist over access and compensation.
What success looks like elsewhere
Early adopters offer instructive templates. Taiwan installed 1.7 gigawatts of offshore wind between 2019 and 2023 despite lacking domestic expertise, achieving this through aggressive localization requirements that forced international developers to transfer technology and build local supply chains. The policy attracted $18 billion in investment and created 20,000 jobs, according to Taiwan’s Bureau of Energy.
Vietnam presents a closer analogue to Kenya’s situation. It developed 500 megawatts of offshore wind by 2023 with Chinese and European backing, leveraging feed-in tariffs of $0.098 per kilowatt-hour to attract investment. However, currency volatility and grid integration problems have since stalled expansion, illustrating the perils of moving faster than supporting infrastructure can accommodate.
For Kenya, the path forward demands pragmatism over enthusiasm. Small-scale demonstration projects, perhaps 50 to 100 megawatts, could validate technical assumptions whilst building regulatory and operational capacity. Strategic partnerships with established offshore wind nations could accelerate knowledge transfer. The African Development Bank’s Sustainable Energy Fund, which has allocated $500 million for renewable energy projects across the continent, represents a potential financing avenue that aligns development with climate objectives.
The Indian Ocean’s winds will continue to blow regardless of whether Kenya harnesses them. The real question is whether the country can navigate the treacherous waters between energy ambition and economic reality, between climate leadership and environmental stewardship. The turbines may yet turn, but only if policymakers, investors, and communities chart a course that acknowledges both the promise and the peril of this untapped frontier.
