Graz Revives Ambitious Geothermal Heating Project as OMV Eyes Exploratory Drilling in 2026 By: Robert Buluma The Austrian city of Graz is once again positioning itself at the forefront of Europe’s geothermal transition after new agreements were successfully renegotiated between the City of Graz, OMV , and Energie Steiermark for a large-scale geothermal heating project that had unexpectedly stalled in late 2025. The revived initiative, centered on supplying renewable heat to Graz’s district heating network, now appears back on track with exploratory drilling potentially beginning before the end of 2026. The development marks a critical moment not only for Austria’s geothermal ambitions but also for Europe’s broader struggle to reduce dependence on fossil fuels amid volatile energy markets, geopolitical instability, and rising heating costs. If successful, the Graz geothermal project could become one of the continent’s most important urban geothermal heating systems, demonstrati...
Nairobi 2029: Africa’s Turn to Host the World Geothermal Congress What It Means for African Baseload Power
By: Robert Buluma
When Nairobi was selected to host the World Geothermal Congress (WGC) in 2029, it marked a historic turning point for both Kenya and the African continent. For the first time, the world’s most influential geothermal gathering will be held in Africa, sending a powerful signal: geothermal energy is no longer a niche technology discussed mainly in Europe, North America, or parts of Asia,it is now firmly rooted in Africa’s energy future.
By edging out strong bids from traditional powerhouses such as Brussels and Germany, Nairobi’s victory underscores Kenya’s growing reputation as a global geothermal leader and positions Africa at the center of critical conversations about clean, reliable, baseload energy.
Why Nairobi—and Why It Matters
Kenya’s selection was not symbolic goodwill; it was earned. Over the past two decades, the country has quietly built one of the most successful geothermal development stories in the world. The Olkaria geothermal fields in the Great Rift Valley have transformed Kenya’s power mix, reducing dependence on hydropower vulnerable to droughts and on expensive imported fossil fuels.
Today, geothermal power forms the backbone of Kenya’s electricity system, supplying reliable, round-the-clock energy to households, industries, and critical infrastructure. This experience gives Nairobi credibility not just as a host city, but as a living laboratory where delegates can see geothermal baseload power working at scale.
Hosting WGC 2029 elevates Kenya from being a regional leader to becoming Africa’s geothermal ambassador to the world.
What to Expect at WGC 2029
The World Geothermal Congress is far more than a conference. It is a convergence point for policymakers, scientists, engineers, financiers, developers, and equipment manufacturers. In Nairobi, the event is expected to be transformative in several key ways.
1. Africa in the Global Spotlight
For decades, Africa’s geothermal potential has been discussed in technical papers and feasibility studies, often framed as “future promise.” WGC 2029 will flip that narrative. Africa will no longer be presented as an emerging market—it will be showcased as an active geothermal frontier with proven projects, expanding capacity, and a pipeline of opportunities.
Countries along the East African Rift System,Ethiopia, Djibouti, Tanzania, Rwanda, Uganda, and Zambia,will use the Congress to present their progress, attract partners, and move stalled prospects into development.
2. Geothermal as True Baseload Power
One of the most important themes at WGC 2029 will be geothermal’s role as baseload energy. Unlike solar and wind, geothermal does not depend on weather or daylight. It operates day and night, stabilizing grids and enabling higher penetration of variable renewables.
For African countries facing growing electricity demand, rapid urbanization, and industrialization, this reliability is priceless. Expect strong focus on how geothermal can anchor national grids, reduce reliance on diesel generation, and support regional power pools.
3. Investment and Deal-Making
Nairobi 2029 will be a marketplace for geothermal investment. Multilateral banks, development finance institutions, private investors, drilling contractors, and technology providers will converge with African governments and utilities.
Key discussions will center on:
Reducing exploration and drilling risk
Innovative financing structures
Risk-sharing mechanisms between governments and private developers
Blended finance and public–private partnerships
For African geothermal projects that have long struggled to reach financial close, the Congress offers a rare opportunity to turn interest into action.
4. Technology Transfer and Skills Development
Africa’s geothermal future depends not only on capital, but on people and know-how. WGC 2029 will emphasize training, capacity building, and localization of expertise.
From advanced drilling techniques and reservoir management to power plant optimization and direct-use applications, African engineers, geoscientists, and regulators will gain exposure to cutting-edge practices. Site visits to Kenyan geothermal facilities will provide practical insight that no classroom can replicate.
Geothermal and Africa’s Industrial Ambitions
Perhaps the most exciting implication of WGC 2029 is how geothermal energy aligns with Africa’s industrial ambitions.
Reliable baseload power is the foundation of industrial growth. Geothermal offers exactly that,clean, affordable, and locally sourced energy that can power:
Manufacturing zones
Agro-processing facilities
Green hydrogen production
Data centers
Mineral processing and value addition
Kenya’s move to link geothermal power with special economic zones offers a blueprint for other African countries. WGC 2029 will amplify this model, encouraging governments to think beyond megawatts and toward integrated energy,industry ecosystems.
The Challenges That Must Be Addressed
Despite its promise, geothermal development in Africa still faces real challenges,and WGC 2029 must confront them honestly.
Drilling costs remain high, especially in early-stage exploration. Access to affordable long-term financing is limited. Regulatory frameworks in many countries are still evolving. Community engagement and land access issues require careful management.
The Congress should not shy away from these realities. Instead, it should become the platform where solutions are agreed upon,regional cooperation, shared infrastructure, standardized permitting, and stronger public-sector leadership in early-stage risk mitigation.
A Turning Point for Africa’s Energy Narrative
Hosting the World Geothermal Congress places Africa at the center of a global energy conversation that increasingly values reliability, resilience, and decarbonization. It challenges outdated assumptions that Africa must rely on fossil fuels for baseload power or wait decades for advanced technologies to arrive.
Nairobi 2029 is an opportunity to redefine Africa’s role,from technology adopter to solution provider, from resource holder to energy leader.
The Bigger Picture
Beyond the speeches and exhibitions, the true success of WGC 2029 will be measured by what follows: wells drilled, projects financed, skills transferred, and power plants commissioned. If the momentum is sustained, the Congress could accelerate geothermal deployment across the continent for the next decade and beyond.
For Africa, geothermal is more than energy,it is stability, sovereignty, and sustainable growth. By hosting the world in Nairobi, the continent is not just opening its doors; it is making a statement.
