Barito Renewables Energy (BREN) is electrifying headlines as its controlling shareholder, Prajogo Pangestu, bolsters his stake, coinciding with a significant geothermal power discovery. This dual development signals robust confidence and a tangible expansion of Indonesia’s renewable energy footprint, positioning BREN as a compelling player in the green energy transition.

Prajogo Pangestu’s Strategic Stake Increase

In a clear vote of confidence, billionaire investor Prajogo Pangestu, the strategic mind behind BREN, recently amplified his direct ownership in Barito Renewables Energy. On January 13, 2026, Pangestu acquired an additional 1.33 million shares, investing approximately Rp11.9 billion (at an average price of Rp8,930 per share).

This transaction modestly, yet significantly, elevated his direct stake from 0.103% to 0.104%. While seemingly a small increment, insider buying, especially from a controlling shareholder of Pangestu’s caliber, often serves as a powerful indicator of future growth potential and a firm belief in the company’s trajectory. It suggests a strategic long-term view that could resonate with astute investors.

Geothermal Powerhouse: BREN’s Hamiding Discovery

Unlocking North Halmahera’s Renewable Potential

Shifting gears to operational expansion, BREN‘s subsidiary, Star Energy Geothermal Indonesia, has announced a groundbreaking discovery that could redefine its generation capacity. Following extensive exploration in Mount Hamiding, North Halmahera Regency, the company confirmed a substantial geothermal power generation potential of approximately 55-60 megawatts (MW). This is a crucial step towards harnessing Indonesia’s vast geothermal reserves, often referred to as the “sleeping giants” of clean energy.

As reported by Kontan, BREN President Director, Hendra Soetjipto Tan, highlighted that the successful conclusion of this exploration phase lays a solid foundation for significant geothermal development across the Halmahera region. This discovery not only enhances BREN’s future revenue streams but also reinforces its pivotal role in supporting Indonesia’s ambitious renewable energy targets and the global shift towards sustainable power sources.

What This Means for BREN Investors

For investors tracking BREN, these dual developments paint a compelling picture of a company potentially poised for upward momentum. Here are the key implications:

• Strong Insider Confidence: Prajogo Pangestu’s increased stake acts as a direct endorsement, suggesting an undervaluation or robust growth outlook from someone with unparalleled insight into the company’s operations.
• Tangible Growth Prospects: The confirmed 55-60 MW geothermal potential represents a concrete pipeline for future energy production and revenue. This isn’t mere speculation; it’s a measurable addition to BREN’s asset base, promising long-term, stable power generation.
• Strategic Market Positioning: BREN continues to solidify its position as a leading player in Indonesia’s burgeoning renewable energy sector, aligning with global trends towards sustainable power and environmental, social, and governance (ESG) investing principles.
• Long-Term Value Creation: Investments in geothermal power are capital-intensive but typically offer stable, long-term returns once operational, providing a predictable earnings stream for decades, akin to a resilient dividend.

As Barito Renewables Energy continues to expand its green footprint and attract renewed confidence from its primary stakeholder, the company charts a course for sustainable growth in the dynamic world of renewable energy. Investors should watch BREN closely as it potentially transforms geothermal potential into tangible, enduring returns.
