Hydropower is the oldest renewable energy source, but aging dams require periodic maintenance. A stabilization project that added high-capacity post-tensioned anchors and new concrete enhanced the Bagnell Dam

Pairing solar energy resources with batteries is a winning solution. It allows utilities to store excess power when the sun is shining but demand is low, and use it when the sun sets but demand is high. One

A greenfield concentrated solar power (CSP) project with novel parabolic trough technology and a molten storage system has revitalized a remote region. But the project is also laudable for its social

The refurbishment of Storr Lochs, a small hydropower plant built nearly 70 years ago at an isolated location in Scotland’s mountainous Isle of Skye, has given the project new life and purpose. The reason

One way to help decarbonize the electric grid is through the use of renewable hydrogen, that is, hydrogen produced from renewable power resources. The process involves using excess wind and solar power during

Today, drones equipped with sensors and cameras are proving their worth in gathering real-time footage that can be stored for later analysis. Uncrewed aerial systems can detect failing structures and equipment

Sonic sootblowers and acoustic cleaners were once thought to be a last-chance alternative to difficult ash build-up problems. However, the technology has proven to be effective over years of service in

COMMENTARY At this point, one thing should be abundantly clear about the Trump administration’s theme on energy policy: the president will do whatever it takes to prop up coal, even if the market and the public choose otherwise. The Trump administration’s latest pro-coal gambit is the Environmental Protection Agency’s (EPA’s) so-called Affordable Clean Energy rule, […]

As many power plants continue to struggle with the critical last step in their coal ash remediation processes – the final testing phase – some plants have successfully adopted the use of recently advanced sensor technology to measure real-time total suspended solids (TSS) to verify their discharge water is meeting specified requirements.

Having the ability to monitor TSS real time, and obtain accurate results that are repeatable and verifiable with random lab tests, allows for users to automate functions such as controlling pumps transporting effluent, or start and stop pretreatment processes designed to keep effluent within permit guidelines.

Coal-fired plants have been powering the electric grid for more than a hundred years, but the technology being used in them is not stagnant, as many advancements have been made. One new design—the Clean

Community solar projects, also known as solar farms or solar gardens, are maturing and moving forward. Minnesota leads the nation with 559 MW of capacity on the ground, and other states are following with new

A major part of maintaining a power plant at peak efficiency is dealing with or preventing damage from corrosion and corrosive objects that can enter air and water intake systems, including pipes and fluid

The hard realities of an energy system based on renewables will soon be with us, causing far more problems than are realized. Renewables don’t offer a quick fix, and we need to get the transition from

I was recently reviewing a report issued last year by BMI Research, a Fitch Group company. The Megatrends 2050 Special Report , as it is called, suggests there are three main trends that will transform the

The world’s nuclear sector is struggling to stay economically afloat amid a deluge of renewables and natural gas power, and reinvigorating it will require operational flexibility from new or existing

An innovative nuclear wastewater treatment approach that could provide a cost-effective alternative to fixed-column ion-exchange plants is poised to enter the nuclear market. Atkins, a company that

An arc flash is the explosive energy released when an electrical fault causes an arc. This rapid release of energy causes excessive temperatures in addition to air and metal in the path of the arc expanding

Economic pressures coupled with new and proposed regulations to reduce air emissions and regulate cooling water use and the management and disposal of coal combustion residuals (CCRs) continue to drive the

Coal is the reason that Healy, Alaska, exists. To ensure low-cost power and reliability to interior Alaska—a remote place that is bereft of gas and has little sun—and sustain regional employment, Golden

Efficiency has become the mantra of modern coal power. The 912-MW hard coal–fired RDK 8, a unit that operates in Germany’s challenging power market, achieved a 47.5% net thermal efficiency through

New coal power plant technology is being developed by various companies around the world, but there are some pretty efficient and reliable designs already commercially available. Circulating fluidized bed

After flowering between 2008 and 2014, power from biomass has withered in the face of market forces. Furthermore, lawmakers in Washington, D.C., have resisted regulatory action that could boost the industry

Shutdown, turnaround, and outage events are extremely complex, with multiple stakeholders all focused on minimizing the time assets are offline, delivering their scope on budget, and ensuring zero safety

State-of-the-art automation systems are common at power plants these days. Still, many plants start up units in a very manual way. When startups were rare, the implications were minimal, but as units cycle

A pilot project was initiated by China’s largest energy provider to test the effectiveness of fog-based power augmentation for a gas turbine at a compressor station. The system provided a significant

The North American Electric Reliability Corp. (NERC) recently issued a regulation for all power producers to test their electrical systems for proper coordination between protective relays. This protective-relay coordination standard number 27 (PRC-27) presents a big challenge for all power plants, but particularly for combined cycle/cogeneration plants, whose lean staffs lack the electrical engineering personnel […]

In line with global emissions targets, energy markets are moving ever more quickly to take up renewables. Such a move is obviously important to ensure carbon reduction targets can be met. This does however create an issue—one that’s not been given the attention it deserves—of the impact this has on the conventional power plants that […]

The Implications of Two Technologies and How They Merge for Next-Generation Intelligence Undoubtedly, as the world becomes more complex and interconnected, digitization and technological innovations are vital components of the global power future. The power industry’s digital transformation is not merely developing alongside the industry, it is infiltrating it—transforming the very fabric of how the […]

Faced with the challenge of making the right moves to accommodate a swiftly changing energy ecosystem, one question draws into sharp focus for generators and the entire power and utilities industry: What will their role become in the years ahead, considering evolving portfolio mixes and changing industry dynamics? Leaders know there’s a very real possibility […]

The pairing of wind and solar is emerging as a smart strategy to implement renewable energy sources with better economic feasibility. The pairing of wind and solar power is an advantageous complement; the two benefit each other. The synergistic combination is an emerging trend in renewable energy and power generation as costs drop.
