LUDECA launched the ROTALIGN Ultra Live Trend, a short-term continuous-monitoring application that helps to accurately determine the relative positional changes between coupled machines during run-up or shutdown. It utilizes the unique ROTALIGN five-axis sensor to monitor continuously, in real time and simultaneously, both the vertical and horizontal parallel and angular displacement of rotating machinery, from cold […]

A recent U.S. Government Accountability Office (GAO) report examines two key options for reducing carbon dioxide (CO2) emissions from coal-fired power plants. The first is horribly expensive and will be years in the making. The second is blocked by current regulations in the U.S. The GAO report “Opportunities Exist for DOE to Provide Better Information […]

Unit 2 at J-POWER’s Isogo Thermal Power Station entered commercial service in July 2009. The 600-MW ultrasupercritical unit joins an earlier, similar plant built in 2002. Together, these two new plants replaced 1960s-vintage coal-fired plants and doubled power generation from the small project site. In addition, the new unit improves the plant’s gross thermal efficiency to about 45% while reducing air emissions to those of a gas-fired combined-cycle plant.

Thirty-six years after work first began at the 1,600-acre site housing the Bellefonte Nuclear Power Plant in Hollywood, Ala., the Tennessee Valley Authority (TVA) in August said it plans to invest $248 million to maintain the option to complete the 1,260-MW Unit 1 reactor. The announcement was made as the nation’s largest publically owned utility […]

Adding two 615-MW supercritical pulverized coal units to the 1,135-MW Oak Creek Power Plant is part of We Energies’ ongoing master plan to “Power the Future” of Wisconsin well into the 21st century. The new Elm Road Unit 1 went into service in February, and Unit 2 is expected to start operations during the fourth quarter of 2010. With operations marked by high efficiency and low emissions, these new units will provide large amounts of cleaner energy to the Great Lakes area.

Australian company Horizon Power opened the country’s first hybrid solar-diesel power station in August near Marble Bar, and it is readying another for operation in the neighboring town of Nullagine, Western Australia—a region infamous for extremely hot temperatures. The power stations are the first “high penetration, hybrid solar-diesel systems” in the world, claims Horizon, adding […]

Located in a semi-arid region, this “Texas tough” coal-fired power plant uses a number of smart practices to increase water-use efficiency. For example, a pipeline was constructed to send blowdown water from nearby Plant X for treatment and recycling at the 1,080-MW Tolk Station, making both plants “zero-discharge” facilities. For its environmental stewardship and superior plant operations, the Powder River Coal Users’ Group named Tolk Station its 2010 Plant of the Year.

Much opposition to large-scale renewable projects concerns aesthetics. U.S. federal regulators, for example, ordered the developer of the $1 billion Cape Wind project—a 468-MW offshore wind farm proposed to be built in a 25-square-mile section of Nantucket Sound off the Massachusetts coast—to change the design and configuration of the project to reduce “visual impacts.” Among […]

Researchers at the University of Leeds in the UK and the Chinese Academy of Sciences say they may have found a solution to dealing with short-lived power demand spikes—and it could be more environmentally friendly and halve the fuel needed when compared with gas-fired generation. Noting that gas-fired generators typically used to feed peaking demand […]
