GE Power signed a landmark deal to provide operations and maintenance (O&M) services for 10 power plants with a combined capacity of 11 GW. Sonelgaz SPE, a state-owned utility in charge of electricity and natural gas distribution in Algeria, owns the facilities. The agreement includes technology upgrades designed to enhance energy efficiency—allowing more than 420 […]

The U.S. Energy Information Administration (EIA) expects natural gas–fueled electricity generation will exceed all other fuel sources once again this summer, marking the third year in a row that gas has been the leader. However, the EIA anticipates electricity generation from both gas and coal will be less this summer than in 2016. The reason […]

The Navajo Generating Station can continue to be competitive under a reduced-price fuel proposal through 2040, said Peabody Energy, the coal giant which owns a coal mine currently fueling the Arizona plant. The utility owners of the Navajo plant on February 16 voted to shut down the 2,250-MW coal-fired power plant in December 2019. The […]

An April 6–issued report released by the World Energy Council suggests that the single biggest worry among global energy leaders is commodity price volatility. Prices appear to be a big concern because of the “Grand Energy Transition” toward de-carbonization. Leaders in resource-holding countries, such as Saudi Arabia, are anxious about long-term economic models, if prices […]

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 […]

Continuous condition-based monitoring of electrical conductors and insulation is an effective way to reduce required plant maintenance activities, cut operating costs, and prevent unplanned shutdowns

Many elaborate planning tools are available to help managers prepare for power plant outages. However, there is something to be said for keeping things simple. One modest tool that some NRG Energy facilities

A power plant’s isolated phase bus is generally reliable, and therefore, maintenance is frequently overlooked. However, the system is too important to neglect. Assessing its condition during minor outages

Technology advancements and new regulatory requirements could reshape how power plant owners operate and maintain large power transformers. Experts outline emerging strategies and call attention to overlooked
