The world’s energy transition took an interesting turn at the end of 2017 as global power firm Engie announced it would switch all its gas operations to biogas and renewable hydrogen, the UK slashed its

Russia’s nuclear engineering and construction firm Rosatom in December brought the fourth unit at its Rostov nuclear power plant (NPP) near Volgodonsk in southern Russia to first criticality. Later that

Polish Energy Company Puts Large Coal-Fired Unit Online. Enea , the Polish state-owned energy company, in December inaugurated what it calls the largest coal-fired power generation unit in Europe. The company

Utility poles are the literal backbone of the electric utility industry. With an estimated 180 million or more in the nation’s power grid, it’s not hard to imagine the monumental task associated with

Turbine water induction protection systems are designed to keep water out of the turbine and prevent damage. Steam turbine damage from water induction is a costly economic, safety, and reliability concern. Any

GE has operated its monitoring and diagnostics center for nearly two decades, examining the performance and health of customers’ power plants and other generating assets around the world. Understanding some

Documents obtained by The Washington Post show the Trump administration is prepared to ask Congress to cut the Department of Energy’s (DOE’s) renewable energy and energy efficiency programs by as much as 72% in fiscal year 2019. The newspaper in a January 31 report says Congress likely would not support many of the cuts, but […]

The future of advanced reactors in the U.S. will remain murky unless the Nuclear Regulatory Commission (NRC) takes four key steps to support innovation and commercialization of new technology, three key industry groups have warned. U.S. leadership of nuclear technology is “at risk,” and if changes aren’t made it will lose its standing as a […]

Public Service Enterprise Group (PSEG) President and CEO Ralph Izzo gave NRG Energy a tongue-lashing for its pointed opposition of subsidies for PSEG’s two New Jersey nuclear power plants. The tense moment at a January 25 legislative hearing that sought to revive the measure is illustrative of a growing chasm within the power sector about the […]

Though some countries, including the U.S., have moved to support coal-fired power generation over the past year, investments in renewable energy continued to rise, according to a new report from Bloomberg New Energy Finance (BNEF). The research group on January 16 said global investment in clean energy such as wind and solar reached about $333.5 […]

A control system that smooths out inter-area oscillations—a problem affecting power systems connected by relatively weak tie lines—has been successfully demonstrated by researchers from Sandia National Laboratories and Montana Tech University. The system that uses smart grid technology could allow utilities to push more power through transmission lines, possibly nixing the need for new transmission […]

Underscoring energy storage’s new vital role in power company operations, Siemens and AES Corp. have launched a joint company, Fluence Energy, that provides technology solutions paired with engineering and services capabilities. AES and Siemens on January 11 announced that Fluence, which merges AES Energy Storage and Siemens’ energy storage team, received all government approvals for the […]

Westinghouse Electric Co., a company that is emerging from a bankruptcy stemming from the half-built AP1000 reactor projects in Georgia and South Carolina, is to be acquired from Toshiba Corp. by business services and industrials company Brookfield Business Partners. Brookfield, a company of Toronto-headquartered Brookfield Asset Management, announced on January 4 that it entered into […]

All power plant equipment has a limited lifetime, but not all components age at the same rate. Some equipment may outlast the useful life of a plant, while other machinery may be replaced more than once

SCANA Corp., a company reeling from a decision to abandon two half-built nuclear reactors at the V.C. Summer project in South Carolina, is getting a lifeline from Dominion Energy, one of the nation’s largest utilities. The two companies on January 3 announced an agreement to combine in a stock-for-stock merger. The proposed deal is valued […]

The equipment showcase section includes products from a variety of vendors that serve the power generation industry. POWER magazine will feature a different power-related equipment category in several issues

Engineers from several companies have worked on upgrades to the technology, including designs that emphasize faster starts, quicker ramp-ups, increased efficiency, and better performance in a tight global

Utilities across the U.S. are aware of beneficial electrification (BE) programs, but wide adoption has been held up by uncertainty about their potential and broader role in the evolving regulated utility

There are many tools available to assist companies as they gain a better grasp on how their energy is being used, and what that means for the goal of efficient energy management. Not all solutions are created

As power plants and substations become more connected, the need for rugged networking equipment built to withstand tough conditions is amplified. The military has already gone through the growing pains, so

The amount of electricity produced by gas-fired power generation has been increasing steadily in the U.S. for more than 25 years. The Energy Information Administration (EIA) reports that in 1990 about 372.8

Unmanned aerial systems—drones—have quickly found their place in the power sector. But as the industry moves out of test cases and experiments, and into full implementation of drones, it is facing a whole

In the next 25 years, the world will turn increasingly to renewables and natural gas to meet energy demand, turning away from coal, according to the International Energy Agency’s (IEA’s) World Energy
