Milestone Alert: Kaishan Group's KK01 Geothermal Power Plant in Kenya Completes All Tests – Set for Commercial Operations (COD)!

Posted by: Alphaxioms Geothermal News

Date:March 6, 2026

Kenya's geothermal sector has achieved yet another significant milestone in the push for clean, reliable, and sustainable energy. On March 5, 2026, Kaishan Group Co., Ltd.(开山集团), a leading Chinese innovator in geothermal technology, proudly announced the successful completion of all independent third-party witnessed tests for their fully owned and operated KK01 (Kaishan Kenya 01) geothermal power station. Located in the prolific Menengai geothermal field in Nakuru County, this 35 MW net capacity plant has now cleared every hurdle, including a rigorous 30-day stability run that began on February 2. With all performance parameters meeting or surpassing design expectations, the independent engineer is poised to issue the final certificate and notify Kenya Power and Lighting Company (KPLC), marking the official Commercial Operation Date (COD) in the coming days.

This achievement is more than just the commissioning of another power plant—it's a testament to the reliability, efficiency, and superiority of Kaishan's advanced geothermal generation technology. The flawless execution of the stability tests, completed on the first attempt, underscores how Chinese engineering expertise is delivering high-performance solutions tailored to challenging environments like the East African Rift Valley.

The Significance of KK01: Pioneering China's "Invest-Build-Operate" Model in Africa

The KK01 project stands out as a landmark in Sino-African energy cooperation. It represents the first fully integrated "investment-construction-operation" geothermal initiative led by a Chinese enterprise on the African continent. Kaishan Group has taken full ownership of the development, from initial investment through construction to long-term operations. This end-to-end approach minimizes risks, streamlines execution, and ensures seamless integration with local stakeholders.

Steam for the plant is supplied by the Geothermal Development Company (GDC),

Kenya's state-owned entity responsible for resource exploration and steam field management in Menengai. The project aligns perfectly with the broader Menengai master plan, which envisions three 35 MW phases totaling 105 MW in the initial rollout. KK01 forms a critical part of this vision, complementing the already operational Sosian Menengai plant (delivered by Kaishan two years earlier) and the ongoing OrPower 22 development (also under Kaishan's influence following their 2023 acquisition of OrPower 22).

Menengai itself is one of Kenya's premier geothermal hotspots, sitting atop vast untapped resources in the Great Rift Valley. With Kenya's total geothermal potential estimated at around 10,000 MW—yet only about 950 MW harnessed as of recent years—projects like KK01 are vital for closing the gap. Once COD is declared, KK01 will deliver stable baseload clean power directly to the national grid, contributing hundreds of gigawatt-hours annually and helping elevate Kenya's renewable energy share toward ambitious national targets.

Over the 25-year operational lifespan, KK01 is forecasted to generate approximately $15 million in annual revenue** for Kaishan Group. This strong financial outlook demonstrates the viability of geothermal investments in emerging markets, where baseload renewables can offer predictable returns while supporting energy security and economic growth.

Kaishan's Growing Footprint in Kenya: From Sosian to Ambitious Expansions

Kaishan's success with KK01 builds on a solid foundation in Kenya. Their earlier Sosian Menengai Geothermal Power plant, a 35 MW facility commissioned in 2023, marked the first independent power producer (IPP) geothermal project to feed electricity into the grid under a public-private partnership model. Utilizing Kaishan's proprietary modular technology—including geothermal steam counterpressure screw expanders combined with Organic Rankine Cycle (ORC) units—the Sosian plant achieved rapid deployment, high efficiency, and cost savings. It has been running reliably for over two years, proving the advantages of modular designs in rugged terrains.

Following the acquisition of OrPower 22 in 2023, Kaishan expanded its role in Menengai. OrPower 22's 35 MW project, with groundbreaking in late 2024 and completion targeted for early 2026, mirrors KK01's capacity and tech stack. Supported by financing from institutions like the African Development Bank (which approved $16.5 million for related Menengai developments), these plants are completing the first phase of Menengai's 105 MW target. A third 35 MW project under Globeleq is also progressing toward mid-2026 operations, further solidifying the field's contribution to Kenya's grid.

Beyond Menengai, Kaishan is pushing boundaries with larger-scale initiatives. In late 2025, the company signed a landmark steam supply agreement with **KenGen** (Kenya Electricity Generating Company) for a 165.4 MW geothermal power plant to fuel the world's first geothermal-powered green ammonia and fertilizer production facility. Located in the Olkaria region, this $800 million project—operated through Kaishan Terra Green Ammonia Limited—will produce up to 100,000 tons of green ammonia annually, plus derivatives like urea and calcium ammonium nitrate for fertilizers (totaling 200,000–480,000 tons per year). By recycling non-condensable gases (including CO2) from geothermal steam as feedstock, the facility aims for net-zero emissions—a revolutionary step in sustainable agriculture and energy.

The green ammonia project, with production slated for October 2027, addresses Kenya's fertilizer import dependency, stabilizes prices for farmers, and leverages geothermal's constant output for energy-intensive processes like hydrogen production via electrolysis. President William Ruto attended the groundbreaking, highlighting its role in food security and green industrialization.

Kaishan's modular screw expander + ORC technology is a game-changer across these projects. Traditional geothermal plants often rely on flash or binary systems suited only to high-temperature resources, but Kaishan's approach enables faster construction (often under 24 months), lower capital costs, greater scalability, and adaptability to varied steam conditions. This flexibility is key to unlocking geothermal potential beyond conventional hotspots, supporting Kenya's goal of exceeding 1 GW installed geothermal capacity in the coming years.

Broader Impact: Advancing Kenya's Energy Transition and Sino-African Ties

Geothermal energy offers unique advantages in East Africa: it's renewable, baseload (available 24/7 unlike solar or wind), low-operational-cost, and minimal in greenhouse gas emissions compared to fossil fuels. Kenya, already a global leader with over 950 MW from geothermal (primarily Olkaria), is targeting further expansion through its Least Cost Power Development Plan and updated National Geothermal Strategy (2026–2036). Incentives for IPPs, streamlined permitting, and international financing are accelerating progress.

KK01's COD will boost the national grid's green proportion, reduce reliance on expensive thermal backups and imports, and enhance energy access for millions. It also exemplifies successful Sino-African collaboration, where Chinese innovation ("为民族工业造'芯'"—forging the "core" technologies for national industry, here in advanced geothermal turbines, expanders, and systems) meets African resource potential to drive mutual prosperity.

This model—technology transfer, local job creation, and long-term partnerships—aligns with Kenya's Vision 2030 and Africa's Agenda 2063. Kaishan's projects create employment during construction and operations, build local skills in geothermal engineering, and contribute to climate resilience amid growing power demand from urbanization, industry, and electrification goals.

Congratulations to the Kaishan team, GDC, KPLC, and all Kenyan partners on this milestone! 🌋⚡🇰🇪🇨🇳

Blowout at Cape Station: Fervo Energy’s First Major Crisis After Blockbuster IPO

Just weeks after a record-breaking IPO, the flagship project of the "geothermal unicorn" faces its first major operational crisis. By : Robert Buluma Beaver County, Utah – The morning of May 27, 2026, began like any other at the Cape Station construction site in rural Utah. Workers for Fervo Energy, the newly public darling of the renewable energy world, were engaged in the complex task of drilling deep into the Earth’s crust to unlock what the company promised would be the future of 24/7 clean power. But by the afternoon, the routine had turned into a crisis. The site had experienced a blowout—an uncontrolled release of fluid or pressure from a well. For any energy company, a blowout is a serious matter. For Fervo Energy, which had just raised $1.89 billion in a blockbuster Nasdaq debut two weeks prior, it represents an immediate stress test of its technology, its safety protocols, and its $7.7 billion market valuation. While the well has since been contained and no injur...

Eavor Geretsried Geothermal Breakthrough: Inside the Closed-Loop Energy Revolution, Drilling Challenges, and Path to Scalable Clean Power

The Geothermal “Holy Grail” Just Got a Reality Check: Inside Eavor’s Geretsried Breakthrough By: Robert Buluma May 22, 2026 It’s not every day a deep-tech energy company publishes a detailed technical report that openly documents what went wrong on its flagship project—and still comes out looking stronger. That’s exactly what Eavor Technologies did with its Geretsried geothermal project in Bavaria, Germany. The result is unusually transparent: part technical post-mortem, part validation of a technology many have doubted for years. And the core message is simple. They built it. It works. But it wasn’t smooth. The short version Eavor is trying to solve one of geothermal energy’s hardest problems: how to produce reliable heat and power anywhere, not just in rare volcanic hotspots. Their claim has always been bold: a closed-loop geothermal system that is scalable, dispatchable, low-carbon, and independent of natural reservoirs. Critics have long argued it wouldn’t survive...

Eavor steps back from operator role in the Geretsried geothermal project

Eavor at the Crossroads: What Geretsried Really Tells Us About the Future of Closed-Loop Geothermal By Alphaxioms Geothermal Insights | May 13, 2026 For years, Eavor Technologies was the geothermal sector's most talked-about enigma. The company raised hundreds of millions of dollars, attracted backing from heavyweights including BP , Chevron , Helmerich & Payne , and Temasek , and made bold promises about a proprietary closed-loop technology that would quietly revolutionise how humanity extracts heat from the earth. But it rarely said much in public. The secrecy was, to many observers in the geothermal community, a feature rather than a bug — protecting intellectual property, managing competitive intelligence, buying time. Now, Eavor is talking. And what it is saying is worth listening to very carefully. In an exclusive interview published on May 13, 2026, by GeoExpro editor Henk Kombrink, Eavor's new president and CEO Mark Fitzgerald — who took the role in October 2025 ...

GEN Electric Grid Impact Study RFP in Framingham Massachusetts Advances Utility Geothermal Networks

GEN Electric Grid Impact Study RFP Signals a Defining Moment for Geothermal Energy Networks in the United States By: Robert Buluma The United States geothermal sector is entering a new phase, one where geothermal systems are no longer being viewed only as sources of heating and cooling, but increasingly as strategic infrastructure capable of strengthening the electric grid itself. In one of the most important emerging developments in utility-scale thermal network deployment, the Home Energy Efficiency Team (HEET), in partnership with Eversource Gas, has officially launched a Request for Proposals (RFP) for a groundbreaking Electric Grid Impact Study focused on Geothermal Energy Networks (GENs), also referred to as Thermal Energy Networks (TENs). Backed by funding from the U.S. Department of Energy under grant “DE-EE0010662.0002 Home Energy Efficiency Team Utility-Managed Geothermal Pilot in Framingham, Massachusetts,” the initiative represents far more than a local energy pilot.

Rodatherm Energy: The Refrigerant Gambit

By: Robert Buluma Rodatherm Energy has done something no other geothermal startup has attempted at commercial scale: swapped water for refrigerant in a closed-loop system. The claim is 50% higher thermal efficiency than water-based binary cycles, achieved by circulating a proprietary phase-change fluid through a fully cased, pressurized wellbore. The company emerged from stealth in September 2025 with a $38 million Series A—the largest first venture raise in geothermal history. Lead investor Evok Innovations was joined by Toyota Ventures, TDK Ventures, and the Grantham Foundation. The engineering thesis is elegant. The execution risks are significant. This is an Alphaxioms examination of both. II. The Thermodynamic Distinction Every geothermal company you've covered moves heat using water or steam. Rodatherm moves heat using a fluid that boils and condenses inside the wellbore. In a conventional closed-loop water system (Eavor's model), water circulates as a single-phase liq...

Steam and Silence: Why Ethiopia's Geothermal Promise Remains Unfulfilled

Steam and Silence: The Uncertain Fate of Ethiopia’s Geothermal Revolution By : Robert Buluma Despite sitting on a volcanic rift valley with over 10,000 MW of clean energy potential, Ethiopia produces just 7.3 MW of geothermal power—enough to power a small town, but a fraction of what the nation needs. For a country long dependent on hydropower (which fluctuates with drought) and biomass (which degrades forests), geothermal offers the dream of steady, 24/7 baseload energy. However, as investigations into the flagship Aluto Langano and Tulu Moye projects reveal, the road from geological promise to actual megawatts is fraught with technical failure, financial gridlock, and conflicting narratives. The Ghosts of Aluto Langano The story begins and, in some ways, remains stuck at Aluto Langano. Developed by the former EEPCO (now Ethiopian Electric Power/EEP), this site is a textbook case of high potential meeting harsh reality. The resource itself is world-class. Data confirms a high-te...

Ormat’s Ormega100: How the World’s Largest 100 MW Binary Unit Is Industrializing Enhanced Geothermal Systems (EGS)

The Geothermal Tipping Point: Ormat’s 100 MW Bet on an Engineered Earth By: Robert Buluma An Analysis of the Ormega100 and the Industrialization of Enhanced Geothermal Systems In the quiet corridors of the Calgary TELUS Convention Centre, amid the hum of the World Geothermal Congress 2026, a threshold was crossed. It wasn’t marked by a flashy prototype or a speculative white paper. Instead, it came in the form of a press release from Reno, Nevada-based Ormat Technologies —a company that has spent six decades drilling, building, and operating quietly in the background of the renewable energy boom. The announcement was deceptively simple: Ormat unveiled the Ormega100, a 100 MW binary power generation unit designed specifically for Enhanced Geothermal Systems (EGS). Buried beneath the technical jargon of heat exchangers and working fluids lies a seismic shift in energy economics. For the last twenty years, the renewable energy narrative has been dominated by the intermittency pro...

Data-Driven Site Selection in Nevada Pushes SLB and Ormat's EGS Development Forward

Breaking Ground Below: How Data-Driven Site Selection in Nevada Is Unlocking the Next Generation of Geothermal Energy Published: June 9, 2026 | By Robert Buluma In the high desert of northern Nevada, where the sagebrush gives way to volcanic rock and the heat beneath the surface has long been a whispered secret, a quiet but profound shift is underway. It is not marked by the dramatic collapse of a coal plant or the sudden rise of a solar farm, but by something far more subtle: the deliberate, data-driven selection of a patch of earth known as Desert Peak. On June 9, 2026, SLB and Ormat Technologies announced that Desert Peak has been selected as the preferred location for a planned enhanced geothermal system (EGS) pilot. This decision, the culmination of a rigorous multi-site evaluation across several of Ormat’s existing geothermal fields, marks a critical inflection point. It is the moment when enhanced geothermal—long a theoretical promise of limitless clean energy—begins it...

Seequent, 400C Energy, and Cascade Institute Join Forces to Map Canada's Deep Geothermal Energy Potential

Beneath the Cold: How the Canadian Thermal Model Could Unlock a Geothermal Revolution By: Robert Buluma Calgary, Alberta – June 10, 2026 — The image of Canadian energy has long been defined by what we extract from the ground and burn: oil sands, natural gas, and coal. But two kilometers below the foothills of the Rockies, and three kilometers beneath the flat fields of Saskatchewan, a different kind of resource is simmering. It is silent, carbon-free, and inexhaustible. It is the heat of the Earth itself. For decades, geothermal energy in Canada has been a tantalizing "what if." The country sits on some of the most significant deep heat reservoirs in the world—the product of ancient continental collisions, radioactive decay in granite batholiths, and the sheer thermal mass of the crust. Yet, compared to Iceland, the United States, or Kenya, Canada’s geothermal sector remains embryonic. The reason is not a lack of heat, but a lack of certainty. On June 8, 2026, standing bene...
