Increasing plant efficiency and reducing maintenance costs is important for economic power plant operation. One part of the task involves keeping the boiler heating surfaces as clean as possible, which increases heat transfer, reduces maintenance, and avoids unplanned standstills of the plant. Shock pulse generators (SPGs) are an innovative and efficient way to manage boiler […]

It’s often said that technology runs well ahead of the law. Not so long ago, the process of setting electric utility rates was only slightly more dramatic than watching paint dry. This was by design. There was generally only one goal—keeping the lights on—and everything else was structured to support it. The utility generated the […]

Owner/operator: SolarReserve Three-and-a-half hours north of Las Vegas, in a rocky, desolate stretch of Nevada desert, an innovative solar-storage plant has nearly completed a year of commercial operations. It also may have delivered proof of round-the-clock dispatchable solar energy. The Crescent Dunes Solar Energy Project, a concentrating solar power (CSP) plant built by Santa Monica, […]

Owner/operator: Pattern Energy Just as Seattle’s Amazon.com jumpstarted the online shopping trend, it’s now part of another trend that has major corporations owning or contracting for sizable grid-connected renewable power facilities. A new wind farm in rural Indiana is part of that story. Cloud computing is big business, and it’s growing as fast as cumulous […]

Owner/operator: Ethiopian Electric Power Corp. Building the 1,870-MW Gibe III hydroelectric project required unprecedented solutions that took into account the remoteness of the site, the narrow gorge where the dam is located, the height of the dam, and challenges in sourcing reliable materials. Split almost diagonally by the East African Rift System, Ethiopia is a […]

Owner/operator: Solid Waste Authority of Palm Beach County/Babcock & Wilcox Co. Although waste-to-energy (WTE) technology is well proven, the relatively low cost of landfilling garbage in the U.S. has foiled new power plant construction for many years. However, a facility in Florida—the first greenfield WTE project the U.S. has seen in 20 years—shows it’s still […]

Owner/operator: Akca Enerji Geothermal energy has long been handicapped by its need for high-temperature resources to generate economic power, but innovations in binary Organic Rankine Cycle systems are making it possible to exploit low-temperature sites. An innovative plant in Turkey using Italian technology has taken things a step further with a unique two-pressure, multistage, single-disk […]

The ocean power sector is still in its early stages of development, shackled by high development and operational costs. Trends emerging over the past two years hint at which technologies could dominate the sector’s future. Despite decades of research and development that have yielded several innovative ways of using oceans to fuel power generation, the […]

Ontario—Canada’s most populous province and its major economic engine—has an electric power supply system so driven by provincial politics that it has pushed the province’s utility generating arm, Ontario Power Generation, into what appear to be incoherent resource policies. Late last September, in a stunning announcement, the Canadian province of Ontario’s Energy Ministry said it […]

God forbid that you have a job that requires you to read the orders issued by public utility commissions (PUCs). As a regulator, I not only have to read them—I have to write them. And even I marvel at the arcane, trial-like proceedings of PUCs and the orders that emerge from them, which are the […]
