Three-phase electric power systems are used for high and extra-high voltage AC transmission lines (50kV and above). The pylons must therefore be designed to carry three (or multiples of three) conductors. The towers are usually steel lattices or trusses (wooden structures are used in Germany in exceptional cases) and the insulators are generally glass discs assembled in strings whose length is dependent on the line voltage and environmental conditions. One or two earth conductors (alternative...
Why technologies are important to grid modernization BY MANI VADARI, Modern Grid Solutions Electricity is one of the cornerstones of our economy. A modern electric grid is critical for our economic and national security. The National Academy of Engineering has called the North American power grid...
Utility distribution systems utilize a variety of connectors to join and attach overhead conductors. These components are simple and relatively inexpensive; however, due to their critical function and the large number of components utilized in the electrical system, they deserve some consideration...
How to optimize the entire outage lifecycle BY RICK NICHOLSON, Ventyx The extreme weather just keeps coming. In 2012, there were 11 outages due to severe weather costing at least $1 billion. The year of 2013 had its share as well. More and more, the scale and variety of such major events are...
How weather affects power quality on the electric grid BY ALDEN WRIGHT & MARK STEPHENS, Electric Power Research Institute Utilities have long understood that weather and grid power quality are closely linked. As anyone who keeps up with the news will note, the last few years have seen a...
The power industry is undergoing a profound transformation driven by grid modernization, renewable integration, and increasing demands for resilience and efficiency. At the heart of this evolution lies the smart substation—a next-generation facility equipped with advanced sensors, digital...
Duke Energy Florida has announced plans to build four new utility-scale solar energy facilities across the state, aimed at adding 300 megawatts (MW) of renewable energy to the grid. This expansion is part of the company’s broader strategy to increase its solar generation capacity and...
In a strategic move to tackle the growing electricity demand and bolster energy security, the U.S. Department of Energy (DOE), under Secretary Chris Wright, has announced plans to focus on expanding baseload and dispatchable power generation. This shift in priorities, outlined on January 5, 2025,...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
The rapid shift toward renewable energy resources (RERs) has placed significant demands on traditional power systems. To address these challenges, modern energy infrastructure is evolving into smart grids, leveraging advanced technologies like Virtual Power Plants (VPPs) to enhance grid...
Louisiana, known for its robust oil and gas industry, is experiencing a significant shift as some of its largest industries express frustration over delays in the state’s renewable energy transition. These major players are pushing for accelerated development and implementation of renewable...
