What Is Meant by Power Factor?

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what affects

MPW Mobile Ultrafiltration and Demineralization Units Exceed Canadian Power Plant Expectations

Challenge:
After a major refurbishment, a Canadian nuclear plant required additional process and boiler feed water for plant start-up and commissioning.
The plant’s raw water supply contained measurements ranging from 1-10 NTU, conductivity from 70-100 and color units ranging from 180-420. The plant also experienced highly variable flow rates, ranging from 0-600 GPM, and issues with the

Using Predictive Analytics to Keep Up with Energy Demand

Silicon Valley Power implemented a system using machine-learning technology to monitor critical power plant components. The solution has proven to reduce downtime and save money. Furthermore, its wireless

The 618-megawatt Edwardsport plant uses state-of-the-art technology to gasify coal, strip out pollutants, and then burn that cleaner gas to produce electricity.

Duke Hit Hard by Exorbitant O&M Costs at Edwardsport IGCC Facility

Duke Energy will swallow $30 million in runaway costs associated with operating its five-year-old 618-MW integrated gasification combined cycle (IGCC) facility in Edwardsport, Indiana, if a settlement the company reached with Indiana consumer groups last week is approved. Duke declared Edwardsport Generating Station “in service” in June 2013, despite a series of hiccups that delayed […]

In an Industry First, Xcel Energy Flies a Drone BVLOS

Xcel Energy on September 12 launched a drone to inspect electric power lines near Fort St. Vrain Generating Station in Platteville, Colorado—marking the first flight by a U.S. utility beyond visual line of sight (BVLOS) during ongoing inspections. Xcel on Wednesday launched a 35-pound drone that is equipped with two cameras, as local, state, and federal […]

Select Boiler Chemistry in the Design Phase of Project Life

On many combined cycle projects, the major decisions about boiler chemistry are left until after the plant has been designed, equipment is procured, and construction is well underway. However, the best time to make these chemistry decisions is in the design phase of the project. That enables the engineering, procurement, and construction (EPC) contractor to […]
