Eavor Demobilizes Rigs from Geretsried: What It Really Means for Closed-Loop Geothermal For three years, two drilling rigs on a farm estate near Geretsried, a Bavarian town about 40 km south of Munich, stood as the symbol of the world's most ambitious closed-loop geothermal experiment. Now in October 2026, Eavor Technologies, the Calgary-based developer of the Eavor-Loop, has told the town and its heating utility that both rigs would leave the site . The company said keeping idle rigs and specialist services on site was costly, and that releasing them would help put the project in the strongest position to continue with Loop 2 once its commercial structure is reworked . On the surface, this is a logistics decision. Underneath, it is one of the clearest signals yet about where first-of-a-kind geothermal technology stands, and how hard it is to turn a technical proof into a bankable business. This article explains exactly what happened, what the move means and what it does not mean...
Three Pertamina Geothermal projects in Indonesia have secured $477 million in international financing
Geothermal Greenlight: How PGEO Just Unlocked $477 Million and a 40% Profit Surge
By: Robert Buluma
If you follow clean energy in Southeast Asia, you already know the name: PT Pertamina Geothermal Energy Tbk (PGEO). But unless you've been staring at their Q1 earnings and the Indonesian government's newly released Green Book 2026, you might have missed just how massive this moment really is.
In the span of one week, PGEO did two things that most renewable energy companies only dream of:
1. Secured $477.87 million in low-cost, sovereign-backed international funding.
2. Reported a 40% year-on-year net profit surge — to $43.90 million — on record electricity generation.
That is not a coincidence. That is a flywheel.
In this deep-dive blog post, we're going to unpack exactly what happened, why it matters for Indonesia's net-zero future, and how PGEO is quietly becoming one of the most compelling geothermal stories on the planet.
Let's get into it.
The Headline That Deserves More Attention
On Saturday, June 6, 2026, PGEO announced that three of its flagship greenfield geothermal projects had been officially inducted into Indonesia's Green Book 2026 — a strategic national planning document published by Bappenas (Ministry of National Development Planning).
In plain English: the Indonesian government just stamped these projects as nationally strategic, giving them immediate access to $477.87 million (Rp 8.6 trillion) in low-interest concessional loans from:
That's not commercial debt at today's brutal interest rates. That is development finance — longer tenors, friendlier terms, and patient capital.
And here's the kicker: PGEO didn't ask for this funding after a bad quarter. They earned it while their net profits were already skyrocketing 40%.
Breaking Down the $477 Million: Who Gets What
Let's get specific, because the allocation tells you exactly where PGEO sees its future.
Sumatra Assets (JICA-led)
· Lumut Balai Unit 3 – 55 megawatts → $158.86 million
· Lumut Balai Unit 4 – 55 megawatts → $148.97 million
Total for Sumatra: 110 MW | approximately $307.83 million
Why Sumatra? Because the geological potential there is among the best in the world. The Lumut Balai field has been in development for years, and these two new units will plug directly into PT PLN's grid with locked-in Power Purchase Agreements (PPAs). That means revenue certainty for the next decade or more.
Sulawesi Assets (World Bank-led)
· Lahendong Units 7 & 8 – 50 megawatts combined → $170.04 million
Total for Sulawesi: 50 MW
Lahendong is already operational. Units 7 and 8 will expand PGEO's share of the regional electricity grid from 30% to 40% — a single-project leap that transforms their market position in North Sulawesi.
Bottom line:
· 160 megawatts of new, clean, baseload power
· Fully financed with concessional loans
· PPAs already signed for Sumatra
That last point is crucial. In renewable energy, financing is only half the battle. Off-take agreements are the other half. PGEO has both.
The Financial Flywheel: 40% Profit Growth in One Quarter
Now let's talk about the numbers that should make institutional investors sit up straight.
PGEO's Q1 2026 financial results (ended March 31, 2026) tell a compelling story. Net profit jumped 40% year-on-year to $43.90 million, up from $31.35 million in the same quarter last year. Revenue simultaneously leaped to $116.56 million, showcasing highly efficient margin conversion.
For context: 2025 was already a record year for PGEO, with total generation hitting 5,095 GWh (up 5.55% from 2024). Then 2026 arrived and accelerated to 15% quarterly growth — first-quarter electricity generation reached 1,370 gigawatt-hours, expanding by 15.22% compared to the previous year.
That is not a mature utility growing at GDP rates. That is a growth company operating inside a utility's balance sheet.
What's driving the profit surge?
Three things:
1. Higher generation volume – More megawatts sold = more revenue.
2. Operational efficiency – Geothermal has high upfront costs but very low marginal costs. Once a plant is running, profit margins expand quickly.
3. Favorable financing – Even before the Green Book funding, PGEO had been refinancing older debt. Lower interest expenses flow straight to net profit.
And now, with $477 million in concessional loans replacing what could have been expensive commercial debt, future margins will look even better.
Why Concessional Loans Are a Bigger Deal Than You Think
If you're new to infrastructure finance, you might be thinking: "$477 million is nice, but aren't all energy projects financed?"
Yes, but the terms matter enormously.
A typical commercial bank loan in emerging markets today carries an interest rate of 8–12% in USD with a tenor of just 5–7 years and strict covenants. Compare that to a concessional development loan from JICA or the World Bank, which offers interest rates as low as 2–4% (sometimes lower), tenors of 15–30 years, and more flexible covenants focused on development outcomes.
For a capital-intensive business like geothermal — where drilling alone can cost $5–10 million per well — the difference is hundreds of millions of dollars in interest savings over the life of the assets.
That's why PGEO's President Director, Ahmad Yani, called the Green Book inclusion a "powerful validation." It's not just prestige — it's balance sheet protection in a high-interest-rate world.
The 3 GW Ambition: Is PGEO on Track?
PGEO has publicly stated a goal of reaching 3 gigawatts of total operational capacity. Right now, they're somewhere around 700–800 MW depending on which units you count.
Adding 160 MW from these three new projects is a 20%+ increase from their current base. That's significant.
But the real story is the pipeline behind it.
Indonesia sits on an estimated 29 GW of geothermal potential — roughly 40% of the world's total. Yet less than 10% is currently utilized. PGEO, as Pertamina's dedicated geothermal arm, has first dibs on the best fields.
The Green Book funding isn't a one-off. It's a template. If PGEO can keep demonstrating execution — on time, on budget, with growing profits — they will keep accessing concessionary capital for future expansions.
Think of it this way: in 2025, PGEO generated 5,095 GWh. In Q1 2026 alone, generation grew 15%. To reach 3 GW by 2030 requires roughly doubling current capacity. With JICA and the World Bank now at the table, that's suddenly a lot more plausible.
ESG Investors: Why PGEO Deserves a Second Look
For global fund managers sitting in London, New York, or Singapore, renewable energy exposure in Southeast Asia often defaults to solar or wind. But geothermal is different — and arguably better in several ways.
First, baseload power. Solar only works when the sun shines. Wind only works when the wind blows. Geothermal runs 24 hours a day, 7 days a week, 365 days a year. That's why PLN loves it — geothermal replaces coal baseload, not just peaking gas.
Second, small land footprint. A 50 MW geothermal plant uses a fraction of the land compared to a solar farm of the same capacity. In a country like Indonesia — with deforestation concerns and biodiversity hotspots — that's a real ESG advantage.
Third, long asset life. Geothermal wells can produce for 30 to 50 years with proper management. Once the upfront drilling is paid off, the cash flows are incredibly stable.
Fourth, local economic impact. Geothermal plants employ local workers for drilling, operations, and maintenance. PGEO has been consistently praised for community engagement around Lahendong and Lumut Balai.
When you add the 40% net profit growth and state-backed financing — this is not a speculative green dream. This is a cash-flow-generating machine with a green halo.
The Macro Picture: Why Indonesia Is Pushing Geothermal Hard
You can't understand PGEO's success without understanding Indonesia's energy trilemma.
First, security. The country is still a major coal exporter, but domestic coal is increasingly unreliable — remember the 2022 export bans.
Second, equity. Eastern Indonesia — Sulawesi, Maluku, Papua — has higher electricity costs and lower access than the western part of the archipelago.
Third, sustainability. Indonesia has pledged net-zero by 2060, or earlier if possible.
Geothermal solves all three at once. It's domestic, it's clean, and it's proven.
That's why Bappenas included PGEO's projects in the Green Book. That's why JICA and the World Bank are writing checks. And that's why PGEO's Q1 profit surge isn't a fluke — it's a policy outcome.
President Prabowo's administration, which took office in late 2024, has made energy independence a cornerstone. Geothermal is the crown jewel of that strategy.
What Could Go Wrong? A Balanced View
No investment thesis is complete without risks. PGEO faces several, and smart readers should know them.
Drilling risk. Geothermal exploration is expensive and not guaranteed. A dry well can cost $5 to $15 million with no revenue to show for it. PGEO has a strong track record, but every new field carries geological uncertainty.
Regulatory changes. Indonesia's bureaucracy is famously unpredictable. A change in tax treatment, export policies, or local content rules could impact project economics.
Currency risk. PGEO reports in USD but earns in IDR from PLN. The rupiah has been volatile — it recently plunged past 18,000 against the dollar. If that trend continues, USD-reported profits will shrink even if IDR profits grow.
Execution at scale. Going from roughly 800 MW to 3 GW requires building multiple 50 to 100 MW projects simultaneously. PGEO has done it before, but not at this speed. Construction delays, supply chain issues, or labor shortages could slow the roadmap.
That said, the concessional loan structure mitigates many financial risks. And long-term PPAs with PLN hedge revenue stability.
How PGEO Compares to Global Geothermal Peers
Let's put PGEO's 40% profit growth in perspective.
Ormat Technologies, a global geothermal leader, has recently seen profit growth in the range of 10 to 15 percent. Enel Green Power, which operates across Europe and Latin America, has delivered mid-single-digit growth as a mature market player. Kenya's KenGen, an African leader, has posted around 20 percent growth.
PGEO's 40 percent year-on-year increase is exceptional for a utility-scale geothermal operator. That's partly a recovery story from post-COVID project delays, partly a policy story from Indonesia's net-zero push, and partly an execution story — Ahmad Yani's team is delivering.
If PGEO sustains 15 to 20 percent generation growth for the next three to five years, they will trade at a significant premium to global peers.
The Lahendong Expansion: A Case Study in Regional Impact
The World Bank's $170 million for Lahendong Units 7 & 8 deserves special attention.
Lahendong is already an operational plant in North Sulawesi. PGEO currently supplies about 30% of the region's electricity. After Units 7 & 8 come online, that share jumps to 40%.
Why does that matter?
Because North Sulawesi is a tourism hotspot — Bunaken, Manado — and a growing economic hub. Diesel and coal are expensive to ship there. Geothermal is locally produced, price-stable, and clean.
The World Bank isn't just funding megawatts — they're funding energy independence for an entire region.
And for PGEO, Lahendong is a blueprint: take an existing field, add units, increase market share, repeat across Indonesia. That's how you get to 3 GW.
What Smart Investors Should Watch Next
If you're considering PGEO — or just tracking the sector — here are four indicators to monitor over the next 12 to 18 months.
First, drilling results for Lumut Balai Units 3 and 4. JICA's money is committed, but actual steam delivery matters. Watch for announcements on well productivity.
Second, rupiah stabilization. A stronger IDR would boost USD-reported profits. A weaker IDR hurts. PGEO's long-term contracts in IDR are a double-edged sword.
Third, additional Green Book inclusions. Bappenas updates the Green Book periodically. If more PGEO projects enter, expect further concessionary financing.
Fourth, Q2 and Q3 2026 earnings. Q1 was spectacular. The question is whether 40% growth is sustainable or a one-off from base effects. Two more quarters of 20%+ profit growth would change the valuation conversation entirely.
Final Takeaway: PGEO Is No Longer a Side Story
For years, geothermal was the quiet cousin of renewable energy. Solar got the headlines. Wind got the subsidies. Batteries got the hype.
But geothermal works. It runs all night. It doesn't need rare earth imports. And in a country like Indonesia — built on volcanic arcs — it's as native as rice and coffee.
PGEO just demonstrated three things.
One, they can access cheap global capital at scale — $477 million proves that.
Two, they can grow profits while doing so — 40 percent year-on-year is undeniable.
Three, they have policy tailwinds — the Green Book, JICA, and the World Bank don't back losers.
That is a rare trifecta.
The 3 GW target is ambitious. The rupiah is volatile. Drilling is never risk-free. But the trajectory is undeniable: PGEO is becoming the blue-chip geothermal play of Southeast Asia.
And for investors who care about both returns and decarbonization? That's a green light worth watching.
