Gas turbine systems produce over one-third of US electric energy requirements. They provide reliable baseload power, in addition to that required to support the intermittent production of electricity from renewable sources. According to a recent Washington Post article, “Turns Out Wind and Solar have a Secret Friend: Natural Gas,” every 0.88% of capacity from renewables …

Sometimes it’s best to start at the end. During Ethos Energy’s October webinar, “L-0 Blade Repairs,” Ian Saeger, manager of project engineering, concluded by stressing that last-stage steam-turbine blade repair is usually at least 50% less expensive than blade replacement and accomplished within a few weeks—if the repair can be done onsite or in-situ. The …

MD&A kicked off its fall 2022 webinar series with a presentation on rotor life extension. You’ll want to take an hour and listen in if your plant has a 7F unit approaching 5000 starts/144,000 equivalent operating hours (EOH) or a 7B through 7EA unit approaching 5000 starts/200,000 EOH. Get the background on these requirements in …
