TVA Begins Operation of John Sevier CCGT Plant

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.


Managing the Catalysts of a Combustion Turbine Fleet

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: More Coal, Then Less

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.


Technology Converts Flue Gases to Jet Fuel

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.


Ukraine Looks Beyond Russian Gas

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.


Will U.S. Natural Gas Inventories Hit Their Caps This Fall?

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.

Wärtsilä’s Latest Combustion Engine Offers New Options for Intermediate Capacity

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.

Saudi Arabia Makes Huge Push to Expand Gas Turbine Generation Capacity

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.
