Power Demand

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

The California Independent System Operator’s Energy Imbalance Market (EIM) is a real-time energy market, the first of its kind in the western U.S. EIM’s advanced market systems automatically find low-cost

At this moment, the lights are on around the country in homes and workplaces.  Most don’t realize, perhaps take it for granted, that those lights come on because of the hard work of dispatchers operating one of the most important manmade systems ever built, the national electric power grid. Without oversimplifying the process too much, […]

Unlike their regulated counterparts, merchant power generators have increasingly struggled to compete over the last few years and the outlook for many is that this won’t change any time soon. While regulated power companies often enjoy near monopolies in their respective markets, merchant power companies build out their power generating capacity on a speculative basis […]

Driven by increased energy efficiency and the relocation of electricity-intensive industries, electricity demand and consumption has steadily declined in many developed markets during the last decade, according to the International Energy Agency (IEA). Yet middle- and working-class households, as well as small businesses, are spending more of their income on electricity than their parents’ generation. […]

It is safe to say that all electricity customers want reliable and resilient power service. One way that some end-users are ensuring they get it is by investing in distributed energy resources and building microgrids. But rather than simply using these systems as emergency backups, more and more owners are finding ways to capture economic […]

Düsseldorf, September 3, 2018 – GEA supplies Saint-Gobain with two Waste Heat Recovery Systems (WHRS) each for the utilisation of waste heat from the float glass production lines in Pisa, Italy and Sriperumbudur, India. Commissioning is planned for the first half of 2019. GEA technology makes it possible to generate electricity and compressed air from […]

The U.S. power system is separated into three major components—the Western Interconnection, the Eastern Interconnection, and the Electric Reliability Council of Texas. The three operate almost independently

Electric vehicles (EVs) have the potential to realign the transportation sector and present an opportunity for the power industry to transform and reinvent itself in fundamental ways. But whether this

The inaugural integrated system plan (ISP) released by Australia’s Energy Market Operator (AEMO) in mid-July warns that the country is in the midst of a “transformative and unprecedented” rate of change

The Frades II pumped-storage hydro project in Portugal took advantage of existing dams to incorporate a scheme that includes the largest variable-speed reversible units installed in Europe. The facility

Do you drive an electric vehicle (EV)? If you answered yes and live in the U.S., you’re among the roughly 1% of drivers doing so in this country. If not, how soon do you think it will be before you become

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long distances

You put in a lot of time choosing the most energy efficient appliances you can find, and you work hard to cut back on energy use around the house. But what if there was a way to make your electric bill even lower with very little effort? Introducing the five gadgets you didn’t know you […]

Solar power generation reached new highs in the United Kingdom recently, with a heat wave and stretch of sunny days across the country highlighting the potential for renewable energy in Britain. Solar produced a record 533 gigawatt hours (GWh) of power from June 21-28. Solar output topped 8 GW on each of the eight days, […]

Germany is often touted as a leader in the global energy transition. Energiewende has been part of the country’s public discourse since the 1970s, stemming from an anti-nuclear movement prevalent at the

General Electric’s (GE’s) power unit has said it will end manufacturing operations at its plant in Salem, Virginia, next year, with more than 260 workers losing their jobs, according to union officials. Officials noted that 42% of the affected workers are eligible for retirement. The plan announced June 8 said the Salem plant, which opened […]

POWER has been reporting for many years on changes taking place in the power generation mix around the globe. Renewable energy, such as wind and solar generation, has been growing steadily in most parts of the

Electricity is produced by a variety of generating units, each with different lead times and costs to be readied for service, and production costs once brought online. Because electricity is a commodity that

Wind power capacity in the U.S., whose explosive growth has tripled since 2008—even overtaking hydropower to become the nation’s largest source of renewable electricity—could face a period of stagnation once the production tax credit (PTC) is phased out in 2021. Analysts at WINDPOWER 2018 in Chicago last week called the period between 2021 and 2026 […]

The operator of the nation’s largest electrical grid on April 30 reiterated its system will remain reliable even with the retirements of substantial generation resources. But PJM Interconnection, whose system covers customers in 13 states, said it will conduct a review of its operations over the next several months “to understand the fuel-supply risks in […]

The traditional electricity grid is being transformed, as more businesses look to control their costs by producing their own power. A need for reliable backup power, the push for more resiliency in generation

The growth in power generation from renewable energy sources, along with the continued shift from coal-fired generation to natural gas, is expected to drive the global market for turbines over the next several years, according to a report released by international business analysts Research and Markets. The Dublin, Ireland-based company in an April 25 news […]

More and more people are finding distributed energy solutions are the answer for their power resource challenges. Distributed energy comes in many forms. Renewables such as solar and wind are top-of-mind when most people think of distributed resources, but natural gas-fired generation is often a good fit too, because it adds reliability to the system […]

Tennessee Valley Authority (TVA) CEO Bill Johnson in an exclusive interview with POWER suggested that the power industry continues to face an uncertain future.  Johnson said that during his 40-year career, he has seen more change in the last five years than in the previous 35 combined. Several indicators imply that will continue going forward. […]

Analysts who spoke with POWER differ slightly on the numbers, but they all agree that U.S. demand for natural gas for power generation will continue to rise. Supply should not be a problem—domestic

Concentric Power, a California-based provider of high-efficiency energy modules for onsite refrigeration and electric power generation, recently launched a $100 million financing program for cogeneration and microgrid projects. “We are excited to create a new path forward in energy infrastructure financing and development,” Brian Curtis, founder and CEO of Concentric Power, said in a press […]

In what has been a much longer and more drawn-out process than Entergy could have imagined when it first proposed a new gas-fired power plant in New Orleans, the company got some good news on February 21. The Utility, Cable, Telecommunications, and Technology Committee agreed—after what has turned out to be years of discussion—to send […]

After decades of lethargic power demand—and negative growth in 2017—U.S. electricity use is expected to grow steadily through 2050, driven by a healthy economy and increasing efficiency, the U.S. Energy Information Administration (EIA) projects in its Annual Electricity Outlook 2018 (AEO2018). However, during that period, direct-use generation will outpace growth in retail sales as more […]
