More Utility Workers in Puerto Rico as Power Restoration Continues

U.S. utilities continue to send workers to Puerto Rico to help restore that country’s electricity and rebuild its power infrastructure, a task that continues more than four months after back-to-back hurricanes left nearly all of the island in the dark. The Puerto Rican government this week said 83% of the island’s generation capacity has been […]

Is the U.S. Too Reliant on Foreign Uranium for Nuclear Power Plant Fuel? [PODCAST]

The nuclear power industry is struggling in the U.S. Several reactors are at risk of early closure due to difficulty competing in the wholesale power markets. New units being built in South Carolina have been abandoned, while the only other nuclear construction project in the U.S.—the Plant Vogtle expansion in Georgia—is behind schedule and over […]


Red and green to grey — Why switch my HMI?

Many operators are perfectly happy with their trusty red and green HMIs and can’t imagine why they should give them up for a dull greyscale display. When they take a closer look, they usually find out that grey is beautiful.

Exercise Proves Hacking a Threat to Nuclear Power Plants

Cybersecurity is a topic covered frequently in the pages of POWER magazine, and one that all power plants need to take seriously. A recent simulation proved that the consequences of a hack can be grave. The drill took place in Sweden, but could have been conducted anywhere in the world. The attack used plant control […]


Test Your Knowledge: Improving Plant Efficiency

Power plants are designed to operate at their highest efficiency. However, once a plant goes into operation, real life takes over and design outcomes are not always realized, which can seriously hurt a plant’s profitability. That’s why improving plant performance and getting back to design conditions should be every operator’s objective. This quiz is designed to test […]
