Ormat gets PPA for Hawaiian Puna Geothermal Increased Capacity

Ormat gets PPA for Expanded Geothermal Capacity at Puna, Hawaii



Ormat Technologies, a leading renewable energy company, has achieved a significant milestone in its mission to provide clean and sustainable power to Hawaii's Big Island. Recently, the Hawai’i Public Utilities Commission (HPUC) granted approval for amendments to the Power Purchase Agreement (PPA), enabling Ormat's subsidiary, Puna Geothermal Venture (PGV), to deliver an additional 8 MW of geothermal energy to the region. This expansion brings the total geothermal capacity at Puna to 46 MW, reinforcing Hawaii's commitment to renewable energy initiatives.


The approval from HPUC comes on the heels of the successful completion of the Environmental Impact Statement (EIS) for PGV's operations in Puna, underscoring the company's dedication to environmental stewardship and compliance with regulatory standards.


One of the key highlights of the newly revised PPA is the consolidation of two existing agreements into one, extending the contract term through 2052. This move provides stability and predictability for both PGV and Hawaiian Electric, with fixed energy rates guaranteed irrespective of fluctuations in oil prices. Such assurances ensure a steady revenue stream for PGV while offering ratepayers consistent energy costs over the duration of the contract.


As part of the agreement, older generation units will be retired and replaced with three advanced and efficient generating units from Ormat. These state-of-the-art units are poised to enhance operational efficiency and reliability, with a projected operational timeline of three years post-HPUC approval.


Doron Blachar, CEO of Ormat Technologies, expressed satisfaction with the extended partnership with Hawaiian Electric, affirming Ormat's commitment to supporting Hawaii's clean energy goals. He emphasized the importance of clean energy and stated, “Ormat is pleased to extend and expand our partnership with Hawaiian Electric and continue demonstrating our ability to support the state’s energy needs."


Jim Alberts, senior vice president and chief operations officer of Hawaiian Electric, underscored the significance of PGV's role in providing firm power for over three decades. He highlighted the positive impact of the new contract on lowering and stabilizing rates for customers while reducing reliance on fossil fuels, furthering Hawaii's transition towards a sustainable energy future.


With the amendments to the PPA, PGV reaffirms its dedication to geothermal development in the region, contributing to Hawaii's broader renewable portfolio mandate goals. The expansion of geothermal capacity not only strengthens the state's energy resilience but also underscores its commitment to combating climate change through the adoption of clean and renewable energy solutions.


Ormat's achievement in securing the expanded PPA reflects its continued leadership in the renewable energy sector and its commitment to driving sustainable development in Hawaii and beyond.

Eavor’s Geretsried Closed-Loop Geothermal Plant Now Powers the Grid

Eavor Technologies Achieves Historic Milestone: World’s First Commercial-Scale Closed-Loop Geothermal System Now Delivering Power in Geretsried, Germany Published: December 2025 By:  Robert Buluma The Day Geothermal Changed Forever On a crisp Bavarian morning in late 2025, a quiet revolution in clean energy officially went live.   Eavor Technologies Inc ., the Calgary-based pioneer of closed-loop geothermal technology, announced that its flagship commercial project in Geretsried, Germany has begun delivering power to the grid becoming the world’s first utility-scale multilateral closed-loop geothermal system to achieve commercial operation. For anyone who has followed the geothermal sector for the last decade, this is nothing short of seismic (pun intended). What Makes Eavor’s Closed-Loop System Truly Disruptive? Traditional geothermal plants rely on naturally occurring hot water reservoirs or enhanced geothermal systems (EGS) that require hydraulic fracturing and massiv...

Exergy ORC Sets New World Record: 46 MW of Geothermal Power in Turkey Delivered in Under 13 Months

Exergy ORC Delivers Two Geothermal Power Plants in Turkey in Record Time: 46 MW Added in Under 13 Months By:  Robert Buluma On November 30, 2025, Exergy International proudly announced the successful commissioning of two new geothermal power plants in Aydın, Turkey: Maren Nezihe Beren 2 (13 MWe) and Emir (33 MWe), totaling 46 MW of new clean electricity capacity. What makes this milestone truly remarkable is the execution speed , both plants were delivered in less than 13 months from contract signing to full commercial operation, setting a new benchmark in the geothermal ORC (Organic Rankine Cycle) industry. Why This Achievement Matters in 2025 In an era where renewable energy projects often face delays of 24–36 months (or longer), completing two binary-cycle geothermal plants totaling 46 MW in under 13 months is nothing short of extraordinary. Turkey already ranks 4th globally in installed geothermal capacity (~1.7 GW as of 2024), and these new plants reinforce the country’s lead...

China Just Built the World’s Cleanest Large-Scale Geothermal Heating System – And Barely Anyone Noticed

China Just Quietly Built One of the Greenest Heating Systems on Earth – And Hardly Anyone Noticed By:  Robert Buluma In a quiet corner of Shaanxi Province, something remarkable just happened. On an ordinary day in late 2025, nine deep geothermal wells in Qishan County, Baoji City, began pumping clean heat from 2,800 meters beneath the Earth’s surface into thousands of homes. No smoke. No coal. No water extracted from the ground and no wastewater discharged back into it. This is China’s first large-scale mid-deep geothermal closed-loop district heating project, and it might be one of the most under-reported green energy milestones of the decade. The Numbers Are Staggering 9 geothermal wells (drilled to 2,800–3,000 m)   100% closed-loop heat exchange – zero fluid leaves or enters the rock formation   Supplies central heating to the entire southern district of Qishan County   Annual savings: 12,000 tons of standard coal   Annual CO₂ reduction: 3...

Iceland Ignites a Geothermal Revolution: ISK 600 Million Bet on Low-Temperature Innovation

Iceland's Geothermal Renaissance: Government Bets Big on Low-Enthalpy and Innovative Uses By: Robert Buluma Iceland has long been the poster child for geothermal energy. With legendary high-temperature fields powering everything from the famous Blue Lagoon to nearly 100% of the country’s electricity and district heating, most people assumed the geothermal story was already written. Apparently not. In a move that has the global geothermal community buzzing, the Icelandic government has just announced a massive ISK 600 million (roughly €4 million / $4.4 million USD) grant program specifically designed to kick-start innovative geothermal projects, with the state covering up to one-third of total project costs. What makes this announcement truly exciting isn’t the money itself (Iceland has funded geothermal before), but the deliberate shift in focus: low-enthalpy resources and non-traditional applications. Why This Matters  The Low-Enthalpy Revolution For decades, Iceland’s geothermal ...

Kenya’s Low Electricity Supply Threatens to Derail Data Centre Ambitions

Kenya’s Low Electricity Supply Threatens to Derail Data Centre Ambitions By:  Robert Buluma Earlier on Alphaxioms.blogspot.com, we explored how the EcoCloud Data Centre project represented  Kenya’s bold leap into renewable-powered digital infrastructure — a model for how clean energy can drive sustainable data innovation. However, new developments suggest that this vision may be facing serious challenges. President William Ruto has revealed that Kenya’s ambitious plan to host world-class data centres powered by renewable energy has stalled due to the country’s limited electricity generation capacity. While Kenya has earned global recognition for its geothermal and wind power leadership, the current generation levels remain too low to sustain the heavy energy demands of data infrastructure. Ruto pointed to Ethiopia’s 5,400 MW mega-dam, commissioned last month — two and a half times Kenya’s total installed capacity — as a clear indicator of the widening energy gap Nairobi must ...
