Fervo Energy’s Latest Drilling Milestone Shows How Enhanced Geothermal Systems Are Becoming Faster, Deeper, and More Competitive Fervo Energy has delivered another eye-catching milestone in the race to make geothermal power more scalable. The company says it drilled Sawtooth 7, the ninth well using its 3.0 well design at Cape Station Phase II, in just 21 days, while reaching 19,448 feet measured depth with a 7,500-foot lateral in a 460-degree Fahrenheit resource [source provided by user]. That is not just a technical achievement; it is a strong signal that enhanced geothermal systems may be moving closer to commercial maturity . This is just a few weeks after it's most exceptional IPO .  What makes this announcement important is the combination of speed, depth, and complexity. Fervo is not claiming a simple fast drill in favorable conditions. It is saying the newest well was deeper, hotter, and longer than its earlier designs, yet still matched the same 70% reduction in drilling...

Tanzania’s allocation of Sh25 billion for geothermal drilling is a clear signal that the country is moving from talk to action on baseload renewables, targeting fields like Ngozi Craters and Kiejo‑Mbaka to diversify its power mix, strengthen energy security and open the door for future geothermal power plants. Tanzania’s geothermal push: from vision to funded wells For years, Tanzania has talked about tapping its substantial geothermal potential to backstop hydropower and reduce reliance on thermal generation , but progress has been slow and mostly limited to studies and early exploration. The recent allocation of Sh25 billion specifically for geothermal drilling changes that dynamic by underwriting the riskiest, most capital‑intensive stage of development: drilling the wells that will confirm the resource.   Drilling is where geothermal projects often stall, especially in emerging markets, because the upfront costs are high and the resource risk is real. Public funding for th...

Zorlu Enerji’s Kızıldere 2 hybrid plant marks a pivotal moment for geothermal‑plus‑solar in Türkiye, transforming an already strategic geothermal asset into a higher‑value, combined renewable facility that can deliver more flexible, resilient and investor‑attractive power to the grid. Image: Geothermal workers onsite  A new hybrid era at Kızıldere 2 Zorlu Enerji has moved Kızıldere 2 from a pure geothermal operation into a hybrid power plant by integrating a dedicated solar photovoltaic (PV) facility alongside the existing geothermal unit. The geothermal plant, located in the Sarayköy district of Denizli in western Türkiye, has long been a flagship 80 MW installation in the country’s renewable energy mix. By adding an approximately 8.5 MW solar PV plant on the same site, Zorlu increases the total installed capacity to around 88.7 MW, while using the same grid connection and site infrastructure.   From a system perspective, the hybrid configuration allows Kızıldere 2 to ...

Dominica: The mandatory seven-day reliability test at Dominica's geothermal power plant resumed on July 1 after engineers successfully resolved the technical issues that caused the island-wide power outages in June.  Image : Dominican Geothermal Power Plant  The plant is currently supplying approximately 10.4MW of electricity to the national grid.Geology Speaking during a press conference on July 2, Prime Minister Dr. Roosevelt Skerrit said engineers and technical specialists conducted extensive investigations into the island-wide power outages experienced on June 17 and 18. He noted that the technical issues were successfully resolved with all corrective measures completed and tested on June 30 which paved the way for the reliability test to resume. PM Skerrit noted that the two outages resulted from different circumstances. However, the investigators found a common issue involving the coordination of protection settings between the battery energy storage system and the geoth...

Hidden geothermal energy under six Tarragona municipalities could power a new phase of the energy transition Image : A Geothermal Power Plant gushing steam to power a grid   A renewable resource beneath the ground A new study in Tarragona has revealed that geothermal energy could become a major local source of heat and cooling for six municipalities: Ascó, Mont-roig del Camp, Montbrió del Camp, Flix, Ulldemolins, and El Perelló . The research suggests that shallow geothermal systems could supply hundreds of buildings and public facilities with a steady, renewable, and locally available energy source . The idea is compelling because it combines climate action with territorial resilience. Instead of depending entirely on imported energy or weather-dependent renewables, these towns could tap into the stable temperature of the subsoil to produce heating, cooling, and domestic hot water . For a region that is already managing the transition away from nuclear dependence, this could ...
