The Tennessee Valley Authority (TVA) has begun commercial operation of the natural gas–fired 880-MW John Sevier Combined Cycle Plant, located near Rogersville, Tenn.
Natural gas–fired fleets comprising diverse turbine unit types are operating their units more these days because of the historic low price of natural gas. With increased operating hours, fleet owners are challenged to find the best ways to manage their SCR catalyst systems.
Europe’s continuing drive toward sustainable energy does not rule out a new generation of coal power plants to replace those scheduled to close by 2015.
A new technology promises major advantages for coal-fired power plants, steel mills, and other industries that produce flue gases—and it could quell concerns about the increased use of arable land and food prices related to the production of ethanol.
Close on the heels of its recent upgrades of the GT26 and GT24 gas turbines for 50-Hertz and 60-Hertz power markets, Alstom in March launched its next-generation GT13E2 gas turbine, a medium-sized gas turbine of the 200-MW class.
For years, tensions have been brewing between Russia, which provides about a quarter of the natural gas consumed in the European Union (EU), and neighboring Ukraine, a country through which 80% of those exports travel via pipeline.
A mild winter and surging shale production have gas inventories at record highs. Absent major production cutbacks, the industry is facing the near-certain prospect of major amounts of gas being dumped on the market later this year.
Once primarily deployed for peaking and industrial use, gas-fired combustion engines are becoming an increasing part of the baseload fleet because of their flexibility and ease of operation. Wärtsilä’s latest engine offers a new level of power and efficiency that can compete with gas-fired combustion turbines in baseload operations.
The Lower Colorado River Authority (LRCA) is slated to replace an aging gas-fired thermal plant outside Austin with a modern combined cycle facility. It’s an upgrade sure to be welcomed as the Texas electric market faces an increasingly murky future.
A fast-growing population means skyrocketing electricity demand for the desert Kingdom of Saudi Arabia. The government is trying to meet this demand head-on with a massive build-out of gas turbine generation capacity, but long-term success will hinge on its ability to produce reliable domestic supplies of natural gas—a problem for a country whose existence has long been tightly tethered to crude oil production.
