An inside look at the rise of HVDC technologies
BY DIETMAR RETZMANN & KARL UECKER, Siemens Energy
The answer to the dreaded cry from towns and neighborhoods against building substations close by may be as simple as a four letter word (or acronym)—HVDC. Short for high-voltage direct current, this evolving technology has numerous applications and benefits. High-voltage direct current transmission systems combine high reliability with a long life expectancy, making this trending technology a powerful...
Often when project developers talk about the cost of a new power plant, wind farm, or solar installation, they’re referring to the capital cost of building a facility. Certainly those development costs have dropped over time—especially for wind and solar. But developers overlook the...
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...
How utilities can protect operations from penetration BY MICHAEL STUBER, Itron For utilities deploying Smart Grid solutions, the major security concern is often the field devices. Utilities and vendors have long understood that field devices such as meters, switches, routers, and concentrators...
Every day across the country, animals enter substations for warmth, food, security, or simply out of curiosity. In many areas, wildlife intruding into power equipment has become the #1 cause of outages, according to a report from the American Public Power Association (APPA) – even...
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...
Direct current (DC) is the preferred technology for moving large amounts of power across long distances. DC results in overall higher efficiency and reliability than an equivalently-sized alternating current (AC) system moving the same amount of power. The Advantages of DC More efficient: Over long...
