Instrumentation & Controls

It’s not being overly dramatic to say that the power industry is at its biggest inflection point to date. Even ignoring the effects of environmental regulations and (in North America, at least) cheap natural

What are distributed energy resources (DERs)? For many people, rooftop solar is the first thing that comes to mind, but when you ask that question of an independent system operator (ISO)—the folks who

In the information technology world, open-source platforms and software, as an alternative to proprietary ones, have long been commonly accepted. In process controls, not so much. That could be changing if some large customers have their way. For decades, the norm with industrial plant distributed control systems (DCS) has been that you buy a proprietary […]

Although the December attack on Ukraine’s power infrastructure mostly affected the distribution grid, generators are just as vulnerable to cyberattack, in part because they tend to rely more on outside contractors working remotely. Here’s the latest on the attackers’ path and methods, areas in generation that are potentially vulnerable, and recommendations to address the vulnerabilities.  […]

Upgrading automation systems can often extend the life of power generation facilities by decades while reducing downtime, improving operations, and reducing required maintenance. The Maggotty plant in Jamaica offers one such example. Many power generation facilities have equipment in good running order with many years or even decades of potential service life remaining, but operation […]

Two senior power sector executives opened the 2016 ELECTRIC POWER Conference and Exhibition in New Orleans April 19 with a message that generators need to “think big” and embrace possibilities of disruptive technologies—or risk being run over on the road to the future. Leo Denault, chairman and CEO of Entergy Corp., delivered the opening keynote […]

The owner and management company of the Berkshire Power Plant—a 252-MW natural gas–fired combined cycle plant located in Agawam, Mass.—agreed to plead guilty on March 30 to felony charges that the companies violated and conspired to violate the federal Clean Air Act. The indictments against Berkshire Power Co. (BPC), the owner of the plant, and […]

Although new microgrid configurations, technologies, and business models are still evolving in the U.S., some lessons have been learned in the past few years. Aside from the fact that financing nontraditional/non-campus microgrids is hard, if there’s one overarching lesson, it’s that a microgrid designed to provide only one benefit or rely on only one generation source is unlikely to succeed.

When we undertook an initiative at Granite Ridge Energy (GRE) to identify, prioritize, and assess components that were due for their 10-year assessments, we didn’t know quite what we were taking on or how to

Malware has apparently been used for the first time to prompt a large-scale power blackout. An attack was tied to a Dec. 23 blackout affecting about 1.4 million Ukrainians living in the Ivano-Frankivsk region, reported Ukrainian news media outlet TSN. However, Slovakian information security firm ESET later confirmed that the reported case “was not an […]

Another megatrend has hit the power generation industry: the Internet of Things (IoT)—countless devices with embedded electronics, sensors, and connectivity to digitally communicate with one another and

The U.S. Senate has approved the Cybersecurity Information Sharing Act (CISA), controversial legislation intended to block the deluge of cyberattacks by opening up communication channels between the private sector and federal agencies.   Senate Bill 754 introduced in March by Sen. Richard Burr (R-N.C.) and co-sponsored by Dianne Feinstein (D-Calif.) passed the Senate by a […]

Before the official start of its Minds + Machines event in San Francisco this week, GE announced the launch of its “Digital Power Plant” during a briefing for the trade press. A formal announcement was to follow in the afternoon. Dick Ayres, general manager of software solutions, power generation services, explained that the company’s Predix […]

Power plants use indicators to monitor process parameters such as pressure, flow, temperature, voltage, current, and vibration. Unless a facility is relatively new, it likely has analog panel meters; some

It’s certainly no secret that for many years, the power industry has been a top target for hackers around the world. However, whereas in the past, many of these attacks were relatively easy to block using

Boundary Dam Power Station Unit 3 is the world’s first operating coal-fired power plant to implement a full-scale post-combustion carbon capture and storage system. It did so more […]

This project is exemplary for the owner’s foresight, maximizing local engineering resources, a stellar safety record, and […]

The global power industry is becoming increasingly complex. Trends toward greater amounts of variable renewable energy are changing the requirements for conventional power plants. Energy market policies are

If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to be much more demanding in actual execution. The first problem is the environment inside the collection hoppers, which is extremely challenging […]

Plant engineers at Eskom’s Majuba Power Station in South Africa have been continuously looking for ways to improve efficiency and reliability. The six-unit, 4,000-MW, supercritical coal-fired plant was experiencing an efficiency decrease of 5% to 7%, which plant engineers determined was caused by poor performance of the actuators on their condensate level control valves (CLCVs). […]

Cybersecurity threats facing the power industry have escalated dramatically in the past few years, as state-sponsored, organized crime, and hacktivist groups all seek to infiltrate U.S. energy infrastructure for cyber-espionage and sabotage purposes. A recent example of the severity of this threat can be seen in operation “Energetic Bear”—a Russian campaign to infect U.S. and […]

Nevada utility NV Energy’s net metering program does not significantly impact homeowners without rooftop solar, according to a study prepared for the Nevada Public Utilities Commission (NPUC) this month.  The study was conducted by San Francisco–based Energy and Environmental Economics (E3) at the request of the NPUC after the passage of a Nevada law last […]

With 4.4 million customers and nearly 46 GW of generating capacity, Atlanta-based Southern Co. has doubled the size of its supervisory control and data acquisition (SCADA) system in the past three years and

Nuclear utilities are facing stringent cybersecurity requirements for plant digital assets that fulfill safety-related, important-to-safety, security, and emergency preparedness functions or that are

Power plants were among the leaders in implementing distributed control systems (DCSs), starting in the 1980s with systems based on mini-computers and continuing through the turn of the century. Although many

Mention the word “drone,” and most people will have a mental picture of what a drone is and does. They likely will think first of military drones carrying missiles and other weapons that could malfunction

Source: POWER During IHS CERAWeek in Houston in early March, POWER Editor Gail Reitenbach sat down with Heiner Markhoff, president and CEO of GE Power & Water’s Water & Process Technologies, to ask him about several issues of concern to power plants.  Though the “water/energy nexus” theme has gained prominence recently, Heiner Markhoff’s comments underscored […]
