Indonesia’s Geothermal Power Surge: Barito Renewables Unleashes Five Game-Changing Projects

A New Chapter in Indonesia’s Energy Future Has Begun.

By: Robert Buluma

In a historic move that signals Indonesia’s unwavering commitment to a greener future, PT Barito Renewables Energy Tbk (BREN) has pulled the curtain back on five cutting-edge geothermal power projects under its subsidiary, Star Energy Geothermal.

The inauguration, which took place virtually on June 26, 2025, was no ordinary milestone—it was presided over by none other than President Prabowo Subianto himself, underscoring the national importance of this initiative.

Set in the lush geothermal landscapes of Salak and Wayang Windu in West Java, these projects aren’t just about generating electricity—they’re about igniting transformation.

🔋 A USD 365 Million Bet on Green Power

Barito Renewables is putting its money where its mission is, investing USD 365 million to inject an additional 112 MW into Indonesia’s energy mix. This expansion is expected to create over 3,300 jobs, supercharging local economies while lowering national carbon emissions.

Hendra Soetjipto Tan, President Director of Barito Renewables, emphasized,

“This inauguration marks our firm commitment to continuously support the government in achieving an energy transition... to contribute to a greener and more advanced Indonesia, especially with the communities around our operating area.”

Vulcan Energy's G-LEP Plant in Landau Paves the Way for Europe's Sustainable Lithium Revolution

Breaking Ground: Vulcan Energy's G-LEP Plant in Landau Paves the Way for Europe's Sustainable Lithium Revolution By: Robert Buluma In the heart of Germany's Rhineland-Palatinate region, a groundbreaking ceremony marked the laying of the foundation stone for the first optimized Geothermal and Lithium Extraction Plant (G-LEP) in Landau, spearheaded by Vulcan Energy Resources, an Australian-German company. As Petra Dick-Walther, State Secretary in the Ministry for Climate Protection, Environment, Energy, and Mobility of Rhineland-Palatinate, described in her recent social media post, this project represents a "quantum leap into the future." It enables the simultaneous extraction of climate-neutral lithium and generation of renewable energy from the hot thermal beds of the Upper Rhine Graben, opening new avenues for Germany's energy transition, supply security, and Europe's sovereignty over critical resources. Lithium, a key component in batteries for electri...

Amsterdam Strikes Geothermal Gold: Hot, Thick, Permeable Reservoir Confirmed

Breakthrough Beneath the Beach: Amsterdam Region Hits Geothermal Paydirt at Strandeiland By: Robert Buluma The Netherlands just took a giant leap toward fossil-free heating. On the artificial island of Strandeiland (part of Amsterdam’s fast-growing IJburg district), the SCAN exploration well has officially confirmed what the geothermal community has been hoping for: a thick, hot, and , most importantly permeable reservoir in the Slochteren Formation. Key numbers that matter:   Reservoir thickness: 152 meters   Bottom-hole temperature: 66 °C   Permeability: confirmed via successful production and injection tests   That’s not screaming-hot by Icelandic standards, but for direct-use district heating in one of Europe’s densest urban areas, 66 °C is more than enough to supply thousands of homes with clean, baseload heat – forever. Why This Well Changes Everything for the Netherlands The Dutch government launched the SCAN program (Seismic Campaign Nethe...

Geo Dipa's Game-Changing Leap: Commercial Silica and Lithium Production from Geothermal Brines by 2028

Geo Dipa's Ambitious Leap: Extracting Silica and Lithium from Geothermal Brines by 2028 Introduction In an era where the global energy transition demands sustainable sources of critical minerals, Indonesia's state-owned PT Geo Dipa Energi ( Persero ) is positioning itself at the forefront of innovation. By 2028, Geo Dipa plans to commence commercial production of silica and lithium extracted from geothermal brines, a byproduct of its geothermal power operations. This initiative not only diversifies the company's revenue streams but also aligns with Indonesia's broader goals of enhancing renewable energy capacity and supporting the electric vehicle (EV) battery supply chain.  Geothermal energy, harnessed from the Earth's heat, produces hot brines rich in dissolved minerals like lithium and silica. Traditionally viewed as waste, these brines are now seen as valuable resources. Geo Dipa's strategy builds on years of feasibility studies and international partnershi...

FINANCING STRATEGIES FOR GEOTHERMAL PROJECTS LEVERAGING TAX CREDIT INCENTIVES

FINANCING STRATEGIES FOR GEOTHERMAL PROJECTS LEVERAGING TAX CREDIT INCENTIVES Aligning Policy, Risk Mitigation, and Investor Capital to Unlock Geothermal Growth Geothermal energy stands at a unique crossroads in the global energy transition. It is one of the few renewable resources capable of delivering continuous, baseload power and heat, independent of weather conditions. Unlike solar and wind, geothermal offers grid stability, industrial heat, and long-term energy security. Yet despite its immense potential, geothermal deployment has historically lagged behind other renewables due to high upfront capital costs, geological uncertainty, and complex financing requirements. In recent years, governments and financial institutions have increasingly turned to **tax credit incentives as a strategic lever to overcome these barriers. By reducing capital expenditure, improving cash flow profiles, and attracting institutional investors, tax credits are reshaping how geothermal projects are fina...

Zanskar’s Big Blind: First Blind Geothermal Discovery in 30 Years

Big Blind: The Geothermal Discovery That Changes Everything By: Robert Buluma Utah startup  Zanskar Geothermal quietly dropped one of the most important announcements in American energy in decades. They discovered and confirmed “Big Blind” ,the first completely blind, commercial-grade geothermal system found in the United States in over thirty years. Let that sink in. No hot springs.   No fumaroles.   No steaming ground.   No prior wells.   Zero surface expression whatsoever. Just desert, sagebrush, and – 7,000 feet below,  a reservoir hot enough and permeable enough to support gigawatt-scale power production. This isn’t incremental progress. This is a paradigm breaker. Why “Blind” Discoveries Matter So Much For the last 40 years, geothermal development in the U.S. has been geographically handcuffed. You could only build plants where nature advertised the resource on the surface – think Yellowstone, The Geysers, or Imperial Valley. Ever...
