Tags: , , , ,

Author: Douglas Morris The new plants that are coming online today are already designed for fast start and flexible operations. With the changing generation mix, being able to move a unit is essential as fleets dispatch more renewables. But what about older plants that were designed to operate as baseload generation? Sometimes units must be […]

Author: Douglas Morris Microgrids are collections of generating sources that are coupled to operate as one either connected to or disconnected from (islanded) the main power grid (sometimes called the macrogrid). Being able to independently provide one’s power is becoming popular with standalone entities like colleges or universities, military bases, and remote locations. Hawaii is […]

In combined cycle power plants: …the heat of the gas turbine’s exhaust is used to generate steam by passing it through a heat recovery steam generator (HRSG) with a live steam temperature between 420 and 580 °C. The condenser of the Rankine cycle is usually cooled by water from a lake, river, sea or cooling […]

Electric utilities must carefully manage their fleet of power generation facilities to improve energy efficiency, reduce emissions, meet regulatory requirements and operate safely. Enabling Industrial Internet of Things (IIoT) technologies provide an opportunity to more effectively manage these fleets than has been possible before. I just found out from Emerson’s Jonas Berge, that his Power […]

Author: Douglas Morris We all know that today’s plants must cycle more; that’s just the expected mode of operation. Keeping plants online with the ability to cycle, particularly cost-competitive combined cycle units, is a focus for most utilities and avoiding heat recovery steam generator (HRSG) tube failures is a good place to start. These failures […]
