Public perceptions can make or break a project. One municipal utility found that out firsthand. When resistance grew strong against a new power plant it needed, the company rebooted and engaged with local

Debate continues over a proposed $1.5 billion power plant that would be built in North Bergen, New Jersey, and would send electricity to New York City. The project includes a 1,200-MW combined cycle facility, along with a 6.5-mile 345-kV underground and submarine cable that would go through Bergen County, under the Hudson River, and connect […]

Duke Energy Florida will commission both units of its new 1,640-MW Citrus gas-fired combined cycle power plant (Figure 1) by the end of 2018. The company on April 3 said the 820-MW Unit 1 will come online in September, with a second 820-MW unit entering service in November. Construction of the $1.5 billion plant began […]

Mulheim, Germany – EthosEnergy has been awarded a rotor exchange contract at a combined cycle power plant in Germany. The contract is for the supply of one fully refurbished GE Frame 6B rotor which will be installed at the next scheduled major inspection. Ulrich Zumbusch, VP of Gas Turbines Europe at EthosEnergy, said “We utilised […]

Digital tools can benefit power plants of all types, yet adding the necessary instrumentation can be costly. However, some of the latest technology doesn’t have to break the bank. Installing WirelessHART

With a broadening portfolio of generation technologies and rapidly changing demands, effectively combining and integrating diverse technologies is important to a reliable power grid. Siemens’ SIESTART

A recent article in The Wall Street Journal heralded the following: “Power Plants Bloom Even as Electricity Prices Wilt.” Understandably, the WSJ editors are excited about the current spate of combined cycle construction projects. I’m also pleased about the growth in our sector (Figure 1). But I’m less sanguine about our ability to execute all […]

Owners and contractors can run into contractual disputes during combined cycle construction projects. Often, the disagreements snowball into lawsuits, which create a lot of activity in attorney offices, but can actually stop activity at the construction site. Engineers and laborers frequently end up taking off their hard hats and setting down their welding torches to […]

Between 2006 and 2015, annual average heat rates from the nation’s natural gas–fired power plants plunged 7%, while only decreasing 1% for coal plants, the Energy Information Administration (EIA) revealed on August 21. Heat rates, which are measured in British thermal units per kilowatt-hour (Btu/kWh), refers to energy conversion efficiency, calculated based on the amount […]

Today’s construction boom in the combined cycle/cogeneration sector is great news for suppliers of gas turbines (GTs), heat recovery steam generators (HRSGs), and engineer-procure-construct (EPC) services. But before this boom advances from artist’s sketches (Figure 1) to first fires, the designers of all those next-generation combined cycles should pause to reflect on the lessons learned […]
