When many older plants were built, steel and cast iron piping were common materials used underground. Although these materials have proven to have long, useful lives, improvements in plastics offer additional alternatives today. An understanding of best practices for inspecting and servicing buried piping will help you keep systems operating as designed.  Most, if not […]

ALLETE Inc., a Minnesota holding company known mostly for its Minnesota Power subsidiary, is making a major strategic transition into the broader world of energy services, exemplified by its recent purchase of U.S. Water Services. At the same time, Minnesota Power, which previously transitioned from hydro to coal, now is shifting to a portfolio of […]

Given the costs and other concerns about currently available technologies for capturing and storing carbon dioxide from fossil-fueled power plants, interest in new technologies remains high. Here’s a look at some potentially promising approaches that are advancing the technology frontier.  Frontiers represent the boundary between the known and the unknown. As researchers attempt to push […]

Sometimes overlooked and underappreciated, a power plant condenser can make or break your efficiency and power delivery goals. Understanding how important a role your condenser plays is a good step toward greater heat rate awareness. As part of a university class on power generation systems that I teach, I show my students a Sankey diagram […]

Advocates for the continued reliance on coal for baseload electricity cheered late last year when North America’s largest power-related carbon capture and sequestration (CCS) facility was commissioned. Since then, that pool of advocates is evaporating as prominent electricity industry decision-makers publicly distance themselves from coal and champion alternatives for a low- or no-carbon future. If […]

How to give electricity customers who can’t take advantage of rooftop solar access to the sun? Community solar—a shared resource—is a fast-growing segment of the renewable energy market, making solar photovoltaic power more accessible while offering another approach to distributed generation. Mention “solar energy” and the image that probably comes to mind is an array […]

With plans for a “permanent” solution for storing waste from nuclear power generating plants permanently stalled, some are hoping that an “interim” site can be developed that would enable the removal of spent nuclear fuel from plant sites. Today, Holtec International and two New Mexico counties announced a memorandum of agreement to build such a […]

With 38 tri-fuel engines and a combined capacity of 573 MW, IPP3—a plant constructed near Amman, Jordan—is now the world’s largest internal combustion engine–based power plant. The facility was inaugurated on April 29 in a ceremony attended by Jordan’s King Abdullah II Ibn Al Hussein. The plant was constructed by an engineering, procurement, and construction […]

Progress has been slow on finding a permanent disposal solution for spent nuclear fuel in the U.S., but an interim solution seems more palatable to developers in a couple of southwestern states. New Mexico Gov. Susana Martinez (R) wrote a letter to U.S. Secretary of Energy Dr. Ernest Moniz on April 11, informing him of […]

Multinational energy giant GDF Suez will henceforth be called “Engie,” a name that reflects the global transition to a decarbonized, renewables-rich, energy-efficient, and digital economy, the company said on April 24.  “As the world changes, all energies change with it,” the largest independent power producer in the world said in a statement announcing the rebranding […]
