Though newer distributed generation options like microturbines, solar, and batteries have grabbed the headlines, diesel remains the go-to option because of its established technology and reliability. But growing competition and new regulations are threatening its traditional role. Here’s what diesel is doing to stay relevant. If you pay attention to nothing but the headlines in […]

One of the world’s largest facilities that harvests energy from ocean temperature gradients began operation this August in Hawaii. The 100-kW ocean thermal energy conversion (OTEC) facility’s inauguration at the Natural Energy Laboratory of Hawaii Authority (NELHA) marks a significant milestone for the technology (Figure 1). One key aspect being tested at the facility is […]

Utility-scale energy storage in the form of pumped water storage has a long history. One of the oldest U.S. plants found itself in need of an upgrade after 40 years of service.

Russia and Vietnam Ink Deal for First Ninh Thuan Nuclear Unit. Russia’s nuclear group Rosatom and Vietnam’s state-owned power company Electricity of Vietnam (EVN) on July 30 signed a general framework

Replacing blades on a wind turbine is not a simple task. Blades range from 40 to 60 meters in length and can weigh 16 tons or more. Combined with hub heights that can exceed 100 meters and locations that are, by definition, subject to prevailing winds, replacing blades becomes challenging. Add in the cost of […]

Shaft collars are used as stops or locators on shafts in a wide variety of applications. There are two basic types. One uses a setscrew to lock the collar in place, while the other utilizes a clamp-type collar. Shaft Collar Designs Setscrew collars are the oldest type of shaft collar. These units function by gouging […]

Alliant Energy and its co-owners are investing $900 million to modernize the Columbia Energy Center with a new suite of air quality control equipment and plant improvements that will increase its output and efficiency while reducing emissions. The plant makeover ensures its continued operation for decades to come. In 2009, Wisconsin Power and Light Co., […]

Owner/operator: TNB Janamanjung Sdn. Bhd. Ultrasupercritical technology is the current gold standard for coal-fired plants, but Malaysian national utility Tenaga Nasional Berhad had some unique requirements for its newest, most efficient plant. With a client lacking an indigenous source of coal and needing wide fuel flexibility, Alstom delivered a state-of-the-art plant that can handle an […]
