Exciting Update: New In-Service Dates for Vogtle Units Revealed

Get ready for a glimpse into the latest developments of one of the most significant energy projects in the US! Southern Company's CEO, Tom Fanning, announced that the schedules for Vogtle units 3 and 4 have been adjusted to allow for any unexpected issues.

Unit 3 is now expected to enter service in May or June, while unit 4 will be operational by the end of this year or early 2024. But it hasn't been a smooth ride, as vibrations in the cooling system caused delays in the criticality process of unit 3. However, Fanning assures investors that the issues have been remediated, and the testing has resumed.


But that's not all! Southern Company is determined to deliver optimal performance and reduce risks associated with any potential issues that may arise. So, extra time has been added to the schedule to address these matters. Metal plates have been inserted into struts connected to the pipe to fix the vibration issue, while repositioning a flange associated with the valve has remedied the dripping valve problem. However, the third issue concerning flow rates through reactor coolant pumps is being investigated.


Despite these setbacks, the lessons learned from unit 3 are being applied to unit 4, ensuring a smoother process. Although the company could have proceeded with the startup program at unit 3, it preferred to fix issues before criticality is reached, ultimately avoiding any potential hazards.


Construction of Vogtle 3 began in March 2013, making it a significant project in the US energy sector. The two AP1000s are the first new nuclear units to be built in the US in over three decades. And Southern Company is determined to get it right, no matter the time and effort needed. As Fanning puts it, "We will not sacrifice safety or quality to meet schedules." The priority remains to provide reliable, carbon-free energy for Georgia for the next 60 to 80 years.

California Unlocks Next-Generation Geothermal Power With XGS Partnership

115 MW of Fire Beneath California: The Deal That Could Redefine Geothermal Power Forever By: Robert Buluma Deep beneath California’s sun-scorched valleys and seismic fault lines lies a force more powerful than wind, more consistent than solar, and more enduring than fossil fuels—a relentless, untapped heat engine that has waited centuries for its moment. That moment may have just arrived. In a bold and forward-looking move, and (CC Power) have signed a landmark agreement to develop 115 megawatts (MW) of next-generation geothermal energy. At first glance, it might seem like just another clean energy deal in a state already known for its climate ambitions. But look closer—and you begin to see something much bigger unfolding. This is not just about adding megawatts to the grid. This is about rewriting the rules of geothermal energy itself. The Sleeping Giant Beneath California California is no stranger to energy innovation. It leads the United States in solar deployment, has aggr...

Beneath Borders: Europe’s Cross-Border Geothermal Breakthrough

Cross-Border Geothermal Power: Europe’s Silent Energy Revolution Introduction: Beneath Borders Lies Power In a world increasingly defined by energy insecurity, volatile fossil fuel markets, and the urgent need to combat climate change, a quiet revolution is taking shape—not above ground, but deep beneath it. Far below the political boundaries that divide nations, heat flows freely. And now, countries are beginning to realize something profound: energy cooperation doesn’t have to stop at borders—especially when the resource itself doesn’t recognize them. The recent geothermal collaboration between Belgium and the Netherlands signals more than just a regional project. It represents a paradigm shift in how nations think about energy, infrastructure, and sustainability . This is not just about electricity. This is about redefining sovereignty in an age of shared resources. Understanding Geothermal Energy: The Power Beneath Our Feet Geothermal energy harnesses the Earth’s internal ...

Peru Confirms New Geothermal Source in the Andes

Peru Confirms New Geothermal Source in the Andes: IGP’s Landmark Discovery Near Paucarani-Casiri Volcano Signals a Clean Energy Revolution for South America By Alphaxioms Geothermal News | April 2026 In a groundbreaking development that could transform Peru’s energy landscape, the Geophysical Institute of Peru (IGP) has officially confirmed the existence of a large-scale active geothermal system in the southern Andes. Located near the Paucarani-Casiri volcanic complex—approximately 75 kilometers northeast of Tacna and close to the Chilean border—this discovery represents a major step forward in harnessing the Earth’s internal heat for sustainable power generation. Announced in late March 2026, the confirmation comes from high-resolution geophysical studies conducted by IGP scientists. It reconfirms what earlier explorations hinted at: the presence of heat reservoirs capable of supporting commercial geothermal electricity production. For a country with vast untapped renewable potential ...

$44.1 Million Powers NexTitan: GA Drilling Accelerates the Breakthrough That Could Finally Scale Geothermal Globally

Revolutionizing the Earth's Heat: GA Drilling Secures $44.1 Million to Accelerate NexTitan – The Breakthrough for Geothermal at Scale By:  Robert Buluma Image: Revolutionizing the Earth's Heat: GA Drilling Secures $44.1 Million to Accelerate NexTitan – The Breakthrough for Geothermal at Scale In a world urgently transitioning to net-zero emissions, geothermal energy stands out as one of the most promising yet underutilized renewable resources. Unlike solar or wind, which are intermittent, geothermal offers baseload power—steady, reliable electricity available 24/7, with minimal land use and near-zero operational emissions. The Earth's subsurface heat is virtually limitless; if harnessed effectively, it could power civilizations indefinitely. Yet geothermal's growth has been stymied by one dominant factor: the exorbitant cost of drilling deep into hard, hot rock formations. Drilling often accounts for up to 70% of total project expenses in conventional geothermal develo...
