China state-owned utility Guangdong Energy Group has started commercial operation of the Dongguan Ningzhou combined-cycle facility in Guangdong Province, China. GE Vernova, which supplied three 9HA.02 gas turbines for the project, on Oct. 24 announced the startup of the power station. The plant is among the largest gas-fired facilities in China. Officials said Dongguan Ningzhou […]

Simple cycle gas turbines provide efficiency levels of around 35% to 40%. Combined cycle units boost efficiency to 60% and beyond. But another option is emerging that combines the attributes of simple and combined cycle designs. This hybrid configuration uses a single power turbine expander and recycles exhaust heat back to the combustor to combine […]

As part of the energy transition journey, there is a global push to prioritize the production of renewable energy sources in the fight against climate change. One solution that is propelling this transition forward is the transformation of waste and residue materials such as used cooking oil (UCO) into renewable fuels including sustainable aviation fuel […]

UPDATED (Oct. 11): The National Oceanic and Atmospheric Administration (NOAA) has upgraded its G4-level “severe” geomagnetic storm watch to a G3-level “strong” geomagnetic storm warning after an anticipated coronal mass ejection (CME) arrived at Earth at 11:15 a.m. EST on Thursday, traveling at nearly 1.5 million miles per hour. The G3-level warning is now in […]

In a significant breakthrough for the development of supercritical carbon dioxide (sCO2) power cycles, the 10-MWe Supercritical Transformational Electric Power (STEP) Demo pilot plant in San Antonio, Texas, has wrapped up Phase 1 testing, demonstrating the commercial readiness of its next-generation indirect sCO2 Brayton cycle. The $169 million project—the largest of its kind in the […]

Mitsubishi Power announced completion of a 5.3-GW natural gas-fired power plant project in Thailand, with the multi-phase installation now fully in commercial operation. The two combined-cycle power plants in Chonburi and Rayong provinces, regions that are hubs for technology manufacturing and services in Thailand, each feature four M701JAC turbines. Mitsubishi on October 9 announced the […]

The Nanko Power Plant in Osaka, Japan, will be upgraded with new gas turbines from GE Vernova. The 1,800-MW station, which was commissioned in late 1990, is replacing three boilers and three steam turbines in an effort to increase the efficiency of the facility and reduce its emissions of carbon dioxide. GE Vernova on October […]

In late 2023, the U.S. Department of Energy (DOE) announced a $7 billion initiative to establish seven Regional Clean Hydrogen Hubs, aiming to scale the use of cost-effective clean hydrogen. This initiative comes as utilities face growing pressures from data centers and other industries that are demanding increasingly large amounts of reliable power. Hydrogen’s role […]

Energy analysts have said the increasing need for reliable baseload power generation means natural gas-fired power plants will become even more important as demand for electricity increases. Several experts who have spoken with POWER noted the availability of natural gas—the U.S. leads the world in natural gas production, far outpacing second-ranked Russia—will drive continued construction […]

The U.S. Supreme Court has said that rules requiring power plants burning fossil fuels to reduce emissions of toxic substances can stand, dealing a blow to several Republican-led states and some power generators that had challenged the regulations. The Environmental Protection Agency (EPA) in May of this year finalized rules on emissions of mercury, after […]
