Indonesian Billionaire Prajogo Pangestu’s $5 Billion Geothermal Bet Could Reshape Philippine Clean Energy A major deal is drawing attention across Southeast Asia’s energy sector: Indonesian billionaire Prajogo Pangestu’s Barito Renewables Energy has made an unsolicited $5 billion offer to acquire Energy Development Corp. (EDC), the largest geothermal company in the Philippines. The proposal, while still non-binding and subject to due diligence and approvals, signals just how strategically important geothermal energy has become in the region’s clean power race. If completed, the transaction would bring together one of Indonesia’s most prominent energy investors and the Philippines’ biggest geothermal operator in a deal that could influence both corporate strategy and regional renewable energy development. Even without a final agreement, the offer alone highlights the rising value of geothermal assets at a time when governments and investors are searching for dependable, low-carbon power...

TAQA and SGI Begin Drilling Tenerife’s First Deep Geothermal Exploration Well: A Major Step for Spain’s Clean Energy Future Image: TAQA equipments in the field  Tenerife crossed an important threshold in its energy transition. The island’s first deep geothermal exploration well, TSA-1, officially entered the drilling phase, marking a historic moment not only for the Canary Islands but for Spain’s wider renewable energy ambitions. For a region long seen as a strong candidate for geothermal development, this is the point where possibility turns into action. The campaign is being carried out by  Soluciones Geotérmicas Integradas , better known as SGI, a wholly owned subsidiary of TAQA , after the project received its critical “Ready-to-Spud” notification from Geotermia de Tenerife, the project owner. That signal may sound technical, but its meaning is simple: all planning, engineering, logistics, and permitting steps are complete, and the drill can finally go into the ground. In...

Designing a baseload geothermal plant is not about hitting a single commercial operation date; it is about building a machine that can run hard, almost all the time, for decades.  Pertamina Geothermal Energy’s (PGE) Lumut Balai Unit 3 project shows what it looks like when an operator bakes reliability, data, and predictive maintenance into the plant from day one instead of trying to bolt them on later. Building Reliability In From Day One: Inside PGE’s Lumut Balai Unit 3 Pertamina Geothermal Energy is developing a 55 MW geothermal plant at Lumut Balai in Indonesia that is scheduled to start operations in 2030, but the critical work is happening now, long before first steam. Rather than treating Unit 3 as a standalone asset, PGE is designing it as part of a living fleet,using detailed data from existing units to guide every major decision. Operations director Andi Joko Nugroho captures the mindset in a single line: “A baseload geothermal plant cannot be designed only to achieve comm...

Close Collaboration on Geothermal Heating Supply Launched in Potsdam Potsdam is taking a major step toward a cleaner and more resilient heating future. Energie und Wasser Potsdam GmbH (EWP) and the GFZ Helmholtz Centre for Geosciences have signed a project agreement that launches a four-year cooperation program to develop additional geothermal sites in the Brandenburg capital. The partnership is designed to systematically unlock the city’s hydrothermal geothermal potential and integrate it into the municipal heating network over the long term. This collaboration matters because the heat transition is no longer a theoretical goal. It is becoming a practical infrastructure challenge for cities across Germany. As older energy systems approach the end of their technical life, municipalities need solutions that are local, dependable, and affordable. Deep geothermal energy offers exactly that kind of pathway, and Potsdam is now positioning itself as one of the cities prepared to make it work...
