Anyone who works in the power industry knows how important fasteners, such as nuts, bolts, and rivets, and gaskets are to plant operation. Fasteners provide structural integrity, effectively holding everything

There is plenty of enthusiasm around hydrogen as a possible alternative fuel to natural gas in combustion processes. Some hope it can eventually replace natural gas in applications such as utility boilers. However, any transition to 100% hydrogen has plenty of challenges to overcome due to it having such fundamentally different combustion characteristics. This gives […]

MeeFog’s very first installation of inlet air fogging was done at Harbor Cogen in Southern California in 1991 on a GE 7EA turbine where it continues to be used for power augmentation to this day (Figure 1). When it was installed, the fogging arrays were placed upstream of the air filters. Since that time, more […]

The chemicals and water present in power generation plants can have a corrosive effect on metal. Integrating fiber-reinforced polymer (FRP) into power plants can help reduce downtime due to maintenance. Power generation plants almost have “too much of a good thing.” The demand for power in the U.S. alone has skyrocketed in the last few […]

Managers know that valves are important to plant operation. That’s why keeping them in top condition is a priority. Upgrading to advanced valve designs and reducing stress on valve materials are just a

Sustainable municipal waste management solutions often involve waste-to-energy plants that can produce electricity while also providing steam to district heating systems. Efficient steam turbines are important

Power companies understand the importance of safety and incorporate many safeguards into plant designs. Yet, the materials used in these defenses also matter, and fiberglass-reinforced polymer (FRP) is an

This month, Virginia Gov. Glenn Youngkin and the Commonwealth’s largest utility, Dominion Energy, announced a request for proposal (RFP) for the development and construction of an advanced nuclear small modular reactor (SMR), and the governor signed Senate Bill 454 designed to facilitate the research, design, construction, and deployment of what will be America’s first commercial […]

Siemens Energy has been awarded a contract by German utility EWE to supply a 280-MW electrolysis system. The plant in the German city of Emden is expected to go into operation in 2027 and will provide up to 26,000 tons of green hydrogen annually for various industrial applications in the region. If this green hydrogen […]

In 2018, Cooperative Energy, a generation and transmission co-op headquartered in Hattiesburg, Mississippi, had an issue to deal with. Several years earlier, it had joined the Midcontinent Independent System Operator (MISO), giving the power provider access to a competitive market. However, Cooperative Energy’s R.D. Morrow Sr. Generating Station, a 400-MW two-unit coal-fired facility that had […]

In approving the development of a 2,800-acre wind farm across prime agricultural land in the east of England, the UK Secretary of State for Energy Security and Net Zero, Ed Miliband, has confirmed what those who understand renewable market dynamics have known all along: That the UK’s energy transition policymaking has been flawed and riven […]

Next-generation, or “next-gen,” geothermal resources have the potential to increase geothermal power generation in the U.S. by twenty-fold by 2050. Next-gen geothermal concepts use technologies developed by the oil and gas industry to engineer reservoirs for geothermal energy generation, vastly expanding the available resource base. Typically, the term next-gen geothermal refers to enhanced geothermal systems […]

Adding new reactors to the U.S.’s fleet of nuclear power plants doesn’t happen every day. In fact, prior to the addition of Plant Vogtle Units 3 and 4, it hadn’t been done from scratch in decades

Brazilian independent power generator Epasa faced significant environmental and operational challenges with heavy fuel oil sludge. Through innovative engineering and problem-solving, the company developed a

The combination of combined heat and power plants with thermal energy storage and industrial heat pumps provides a sustainable and efficient heating sector option. In recent years there has been a growing

Risks posed by geomagnetic disturbance (GMD) and electromagnetic pulse (EMP) events add challenges to an already complex power system environment. But they remain crucial to address. How prepared is the power grid to withstand these powerful natural and man-made disturbances? On the evening of May 10, grid operator PJM Interconnection activated a rare geomagnetic disturbance […]

High-voltage power transmission systems are more important today than ever before because power generated at renewable energy sites in remote locations must often be transmitted to distant load centers. Several state-of-the-art projects being done around the world are reviewed below. The majority of major electric power transmission lines in the U.S. are 115-kV, 230-kV, or […]

In the U.S., regional transmission organizations (RTOs) and independent system operators (ISOs) are responsible for overseeing the reliable operation of the high-voltage transmission system within their respective regions. In other countries, transmission system operators (TSOs) perform similar roles. In most cases, the primary objectives of these entities are to ensure the reliable and efficient operation […]

As coal, gas, and nuclear plants are retired, and wind and solar resources are added to the power grid, stability can become a problem. Understanding the solutions that are available to help manage potential issues is important for decision-makers so they can select the best options for their system. Grid stability and system strength have […]

Decarbonization goals call for advancing high-impact energy technologies. The U.S. has pledged to achieve net-zero emissions by 2050, a goal that presents both challenges and opportunities in the field of advanced materials. This ambitious goal requires a wide range of technological advancements to enable the shift from fossil fuel-based systems to more sustainable and low-carbon […]

Entergy Texas filed an application with the Public Utility Commission of Texas (PUCT) for approval to build two natural gas power plants—one in Jefferson County and the other in Liberty County. “The Legend and Lone Star Power Stations will address the critical need for increased power generation capacity, support increased economic activity throughout the region, […]
