Adjusting Power Line Sag in Real-Time

Getting proper sag between power line towers can be time-consuming. However, a new surveying tool allows workers to make adjustments in real-time. The method saves time and money, while also providing

Equipment Showcase: Instrumentation and Control

The power generation industry is constantly evolving, with advanced technologies becoming more ubiquitous in power plants. Along with this evolution, instrumentation and control equipment continues to be key

MPW Mobile Ultrafiltration and Demineralization Units Exceed Canadian Power Plant Expectations

Challenge:
After a major refurbishment, a Canadian nuclear plant required additional process and boiler feed water for plant start-up and commissioning.
The plant’s raw water supply contained measurements ranging from 1-10 NTU, conductivity from 70-100 and color units ranging from 180-420. The plant also experienced highly variable flow rates, ranging from 0-600 GPM, and issues with the

Three Things ICS Security Pros Can Do to Maximize Uptime

Before industrial control systems (ICSs) were network-connected, operators had little to worry about in the way of cyber threats. But as industrial environments, such as energy utilities, become more connected, they’re exposed to vulnerabilities and attacks. ICSs are used in large amounts of critical infrastructure, including the electrical grid, transportation systems, and wastewater plants. How […]

The Impact of Environmental Regulations on Power Generation

For many years, air pollution control (APC) rules and regulations have governed the design and economics of the world’s power generation fleet. These rules have had a tremendous impact, improving air quality

Equipment Showcase: Tools and Safety Products

Safety should always be a priority for any business, no matter the industry. This is particularly true for power generation facilities, which feature multiple pieces of complex machinery that can present risks

Eliminate Transient Vacuums by Air Injection

Most operators know that air should be kept out of a heat exchanger’s cooling water supply line. Air can collect in pockets and block flow, increasing velocities, increasing system resistance, decreasing

Cleanup and Closure Projects on a Massive Scale

Thousands of workers are involved, and billions of dollars are being spent, as U.S. utilities convert and close dozens of coal ash impoundments in an effort to meet government regulations and prevent future

Power Plant Control Loop Tuning and Optimization [PODCAST]

Optimizing power plant control systems can be challenging, but new tools are available to simplify and improve the process. On this episode of The POWER Podcast, Executive Editor Aaron Larson spoke with Jon Towslee, digital engagement leader for ABB Inc.’s Industrial Automation Power Generation & Water business. Towslee explained how ABB Ability is focused on […]

Contamination Found in Water Near Illinois Coal Ash Dumps

Analysis based on testing mostly conducted by energy companies shows that water near all but two coal plants in Illinois is contaminated with toxic waste. The Chicago Tribune on November 28 reported that a compilation of industry-supplied data from 24 Illinois coal plants shows harmful levels of arsenic, chromium, lead, and other heavy metals in […]
