TOP PLANTS: Claus C Combined Cycle Power Plant, Massbracht, Limburg Province, Netherlands
The 1,309-MW Claus C power plant showcases the successful repowering of an existing steam power plant by upgrading it and adding a highly efficient combined cycle plant that doubles the original plant’s power output for just a 35% increase in fuel consumption. In addition, the newly retrofitted plant is cutting CO2 emissions by 40% compared with a simple-cycle gas-fired plant of equal capacity.
TOP PLANTS: Glow Phase 5 Combined Cycle/Cogeneration Project, Rayong, Thailand
Glow Energy’s 382-MW Glow Phase 5 power plant in Thailand exceeded early expectations by packing into a tightly constrained space more capacity than anyone thought possible. The plant’s engineering feat earns it recognition as a POWER Top Plant for 2012.
TOP PLANTS: Enecogen Power Station, Rotterdam, Netherlands
The Dutch utility Eneco and the Danish energy group DONG Energy recently collaborated in building the 870-MW Enecogen Power Station that has a thermal efficiency above 59% and is designed for maximum operational flexibility. As part of Eneco’s strategy to lower emissions across its fleet, the combined cycle plant is designed to quickly compensate for intermittent power produced by the utility’s wind turbines.
TOP PLANTS: John Sevier Combined Cycle Project, Rogersville, Tennessee
The Tennessee Valley Authority (TVA) is known for its large fleet of coal-fired plants. With TVA’s renewed emphasis on nuclear power and gas-fired generation, the organization will soon fulfill its new goal: “to be one of the nation’s leading providers of low-cost cleaner energy by 2020.” Construction of the 880-MW John Sevier Combined Cycle Plant puts TVA one step closer to achieving that goal.
TOP PLANTS: LCEC Generation Plant, Lovington, New Mexico
Faced with the need to begin generating its own power after decades of relying on larger regional suppliers, and impending renewable portfolio standard requirements, the Lea County Electrical Cooperative had to get creative. Its choice of a highly flexible gas-fired engine plant that will work together with a nearby wind farm makes this a POWER Top Plant.
TOP PLANTS: Lodi Energy Center, Lodi, California
Set to begin commercial operation on Sept. 17, 2012, the 280-MW Lodi Energy Center is the first “fast-start” combined cycle power plant in the U.S. The advantages of the gas turbine’s shorter startup capabilities are reduced fuel costs, lower emissions, and the versatility to effectively partner with intermittent renewable energy sources. The new power plant is located next to the city of Lodi’s municipal wastewater treatment plant and uses its treated wastewater for cooling purposes.
TOP PLANTS: University of Iowa Research Park Tri-Generation Power Plant, Iowa City, Iowa
As part of the University of Iowa Research Park’s efforts to promote renewable energy use, the new campus power plant’s engine generators are designed to operate primarily on landfill gas when the pipeline from the Iowa City Landfill is completed, with natural gas as a secondary fuel source. To make it more efficient, the plant’s waste heat recovery system captures waste heat from the gas engine generator’s cooling and exhaust systems to produce hot water for heating, or chilled water for cooling, campus facilities.
Chile’s Power Challenge: Reliable Energy SuppliesDroughts, unreliable gas imports, and protests against proposed projects have hampered the Chilean power sector and its largest economic driver, the copper-mining industry. Recent policies designed to foster more reliable supplies are a move in the right direction, but remaining obstacles are formidable.
O&M and Human Stresses Caused by Low Gas Prices
Plentiful supplies of low-cost natural gas have changed unit dispatch orders across the U.S., led to thermal stress–induced maintenance issues at cycling coal plants, and resulted in management challenges at coal and gas units alike. This scenario is unlikely to change so long as gas holds its competitive edge over coal.
Partners in Reliability: Gas and Electricity
The natural gas and electricity industries have entered into an increasingly codependent relationship as coal-fired electricity gives way to natural gas–fired generation. Both industries are firmly committed to providing reliable service, although each goes about its business in different ways. Utilities, regulators, and stakeholders are searching for ways to align interests and expectations.
Too Dumb to Meter, Part 4As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road from its origin as a tightly controlled military program to civilian applications meant to benefit society as a whole. In this POWER exclusive, we present the fourth and fifth chapters, “What Friendly Atom?” and “The Atomic Chimera.”
Water and Power: Will Your Next Power Plant Make Both?
In much of the developing world, two essentials are often in short supply: potable water and reliable electricity. Some countries have invested heavily in desalination and combined cycle technologies to simultaneously solve both problems.
Water Conservation Options for Power Generation Facilities
The electric power industry is a large water user and is dependent upon reliable water supplies. Adopting new water-conserving technologies for power production can help alleviate the impact of future water shortages. Several water use reduction technologies are available, each with different benefits and costs.
