While low-voltage cable often refers to what is used to wire audiovisual and fire alarm equipment, it also describes lower voltage electric grid distribution cable, as contrasted with the high-voltage cable used on transmission lines.
In January, the National Energy Board (NEB) of Canada announced that it has approved the Lake Erie Connector Project, a 117-kilometer (km) international transmission line that will connect Ontario with Pennsylvania, running under Lake Erie.
An increasingly connected world means that power outages of any kind are becoming more costly. For data center and IT managers, the consequences of such outages are even more significant. Unfortunately, the risk of outages doesn’t seem to be going anywhere anytime soon.
In November, as part of a larger plan to decarbonize the power supply and transportation in Columbus, Ohio, American Electric Power (AEP) announced plans to invest $52 million to build between eight and 10 microgrids in and around the city.
Microgrids are the hot new idea that’s been around forever. Thomas Edison’s first New York City power plants could be considered microgrids because those generating stations each acted independently from the others, serving their own “islands” of connected loads.
Transformative technologies have almost become the new norm in the age of digital communications and renewable power. For example, consider the impact of cell phones, Wi-Fi, the internet, wind and solar power, and electric vehicles on the industries, markets and consumers that have adopted them.
As the power sector evolves to accommodate innovations such as renewables and efficiency, utilities and providers have not always embraced change.
However, conservation proponents won a national battle recently, when the U.S. Supreme Court upheld a regulation supporting demand-response programs.
Denmark is shaping up to be wind power's sweetheart. In 2015, it generated 42 percent of its power with wind turbines. It is the highest portion of any country's energy needs fulfilled by wind. And Denmark is no stranger to this podium.
As our energy mix changes, the need to improve the infrastructure for delivering that power also grows. Utilities recognize that need and are investing in upgrades to their delivery systems. Customers in New York and Pennsylvania are about to benefit from one such upgrade.
A report published by Navigant Research, “Direct Current Distribution Networks,” examines the opportunity for direct current (DC) distribution networks in four key market segments: off-grid/bad grid telecommunications, data centers, commercial building grids and off-grid military applications.
San Diego Gas & Electric’s (SDG&E) microgrid supplied electricity to 2,800 customers in Borrego Springs in San Diego County, Calif., on May 21, 2015, during planned grid maintenance. This marked the first time a U.S.
In the energy field, who we receive our power from and what we receive may soon be our choice. In fact, some customers are already in the driver’s seat through something called community choice aggregation (CCA).
In January 2013, the Edison Electric Institute—the leading advocacy group of the investor-owned utility industry—released a report predicting “significant future disruption to the utility business model,” thanks to growing adoption of distributed generation resources.
As in any industry, the landscape of utilities is always changing. Part of this dynamic is fueled by the need for big companies to strengthen their positions and maximize profits. Those same motives fueled a recent acquisition that produced a new giant among the nation’s electric utilities.
The landscape of power in this country is changing at a rapid pace. Forces external to the industry, such as climate change, and those with a more intrinsic link, such as technology and consumer demand, have combined to place great pressure on the nation’s delivery system.
