The Importance of Including Balance-of-Plant Systems in Condenser Maintenance
Keeping a power plant’s surface condenser in proper working order requires paying attention to balance-of-plant systems as well. Failure to monitor and maintain cooling towers and vacuum pumps in particular can lead to performance penalties or worse. The surface condenser at a power plant has a significant effect on power generation—specifically, the efficiency with which […]

German Companies Hope to Take Energiewende to Iran
Taking full advantage of the international political thaw with Iran, Germany has begun working closely with the fossil fuel–rich nation to develop renewable energy strategies based on the successes and failures its policymakers have learned from its own Energiewende (energy transition). To jumpstart this, Germany’s government recently released a commissioned report titled “Enabling PV Iran,” […]

Are Open System Controls Coming to Power Plants?
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 […]

Why Power Generators Can’t Ignore the Ukraine Cyberattack
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. […]

Digital Control System Upgrade Gives Hydropower Plant New Life
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 […]
