Intensifying drought conditions in California and historically low water levels at the Oroville Dam on Aug. 5 forced the state’s Department of Water Resources (CDWR) to shut down the 644-MW Edward Hyatt Power Plant—the fourth largest energy producer of all California’s hydroelectric facilities. Similar conditions across the West are prompting a careful watch over hydropower facilities.

West Virginia’s only remaining coal refuse–fueled facility, the 80-MW Grant Town Power Project, is a 2021 Top Plant winner for powering on, despite challenges, to remediate 530,000 tons of coal refuse annually while reclaiming roughly 30 acres of land per year. 

Korea Western Power’s Taean Integrated Gasification Combined Cycle (IGCC) Power Plant this year marked 4,000 hours of consecutive accident-free operations, setting a new world record for IGCC power plants

China in late June began operating two of the world’s first 1-GW hydropower turbines at the Baihetan Hydropower Station in southwest China. When the project’s 16 generating units are completed by July 2022

Winning POWER’s highest honor is Track 4A, Southern Power Generation’s 1.4-GW natural gas–fired power plant in southern Malaysia that is equipped with the first commercial GE 9HA.02 gas turbines—one of

Water treatment professionals often turn to chemicals to control algae in power plant settling ponds. While this can be effective, environmentally friendly ultrasonic technology may do a better job at a

Unlike backwash systems, scraper strainers reliably resist clogging and fouling when faced with micron-sized particles, oversized solids, and high solids concentration. The power generation industry often prefilters raw water from rivers, lakes, gulfs, and coastlines to remove organic, aquatic, and other solids for use as cooling water. Typically, with once-through systems, water circulates through pipes, […]

An adiabatic cooling tower system can save great amounts of water at power plants compared to typical wet-type cooling towers. While there are challenges to implementation, understanding how these systems work

Power plants across the globe are looking for an alternative to traditional chemistry to manage the water used throughout the cooling process. An innovative non-chemical water treatment technology may offer

The new DuPont™ B-Free™ pre-treatment technology reduces operational costs and boosts plant uptime and reliability. WILMINGTON, Del., March 30th, 2021 – DuPont (NYSE:DD), a global science and innovation leader, today announced the launch of a new pre-treatment technology that eliminates the effects of biofouling in Reverse Osmosis (RO) systems to reduce operational costs and to […]

Integrated solution set to increase water capacity, drive operational efficiency and ensure clean, safe and dependable delivery of water to all residents McLean Technology Group (MTG) has employed ABB to deliver automation, electrification, and instrumentation solutions at Nashville’s Central Wastewater Treatment facility, managed by Metro Water Services (MWS), as it looks to address the needs […]

ABB technology is being used to build the world’s largest desalination plant in Taweelah, Abu Dhabi, United Arab Emirates. The USD 500 million development will have the capacity to process over 900,000 cubic meters of seawater per day, enough to meet the demands of over 350,000 households. Approximately 45 kilometers north of Abu Dhabi city, […]

Steam plays a prominent role in the Power Industry. When a boiler goes down, companies can be faced with a potential loss of hundreds of thousands of dollars for each minute of lost production time. Although many plants operate 24/7 without interruption, it is very likely that a temporary steam plant will be required at […]

NIPSCO uses a large reservoir for settling out suspended solids prior to discharging the water back to the Kankakee River. This water is rich in nutrients, causing algae to grow at an undesired rate. Algae has a direct effect on pH and TSS levels in water. By using LG Sonic MPC-Buoy systems, NIPSCO has improved […]

Flow-accelerated or flow-assisted corrosion (FAC) is the uncontrolled dissolution and transportation of iron oxides in a steam-water cycle system that occurs in both single-phase locations (water) and two-phase locations (water and steam). Single-phase FAC can be mitigated by chemical controls, but two-phase FAC remains largely unaddressed by industry’s available product options due to the challenging nature […]

It is well-known that a conventional boiler or heat recovery steam generator (HRSG) and related steam turbine have innumerable pieces all working in conjunction to produce the end product of electric power. In

In the late 1960s, the U.S. was facing an environmental crisis. Air pollution was a serious problem in cities across the country, industrial activities and the widespread use of hazardous pesticides were

WASHINGTON, D.C. (Nov. 24, 2020) – The U.S. Department of Energy today announced $35 million in funding for 11 projects as part of the Advanced Research Projects Agency-Energy’s (ARPA-E) Submarine Hydrokinetic And Riverine Kilo-megawatt Systems (SHARKS) program. SHARKS teams will develop new economically competitive Hydrokinetic Turbines (HKT) designs for tidal and riverine currents. “Hydrokinetic energy […]

Decarbonization is posing a fundamental dilemma that could have widespread serious implications for the power sector: the clean energy transition, if not properly managed, could increase water stress, or be

The U.S. Department of Energy (DOE) on Sept. 6 took the rare but drastic action of issuing an emergency order under the Federal Power Act (FPA) to authorize the maximum operation of three natural gas–fired facilities on the California Independent System Operator’s (CAISO’s) grid whose full capability had been stranded by federal air quality and […]
