combined cycle gas turbine

Natural gas–fired power generation has seen its ups and downs over the past couple of decades. In some cases, highly efficient combined cycle units were taken offline because they just weren’t needed. But

In recent years, the use of single-shaft combined cycle power plants has steadily increased in the U.S. While multi-shaft configurations are advantageous in certain scenarios—for example, when layout flexibility or phased installation is needed—single-shaft designs have proven to be a highly efficient and cost-saving option for power plant owners and operators seeking to maximize the […]

A partnership between one of the nation’s largest utilities and one of the world’s largest construction contractors resulted in the 1,100-MW Paradise Combined Cycle Plant in Drakesboro, Kentucky, next door

Varnish buildup in oil systems and components can degrade performance and cause erratic valve operation. Some experts have conducted research and formulated new lubricants that could help solve those problems. One such oil proved highly successful during a five-year run at a gas turbine power plant. By eliminating the need for oil changes and valve […]
