In recent years, the cost to bury high-voltage power lines has decreased dramatically. The American Transmission Company reports that installation costs for underground transmission lines (over 100 kilovolts) are now only 2.5 to 10 times the cost of an equivalent overhead line. Consequently, the number of underground transmission line projects has exploded in recent years and the number of underground high-voltage power lines operating in the United States have dramatically increased.
To date, overhead...
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 to improve reliability by hardening the power grid BY BO ZENG, WEI YUAN & LONG ZHAO, University of South Florida North America relies heavily on its interconnected power grid. Throughout its history, the grid has provided years of reliable electricity to 300 million people to power home...
Moving utilities toward a modern energy system BY RONNY SANDOVAL, Environmental Defense Fund The need to build a smarter energy infrastructure has never been greater. Storms and other extreme weather events such as Hurricane Sandy continue to test the limits of the existing, century-old electric...
Connecting the ‘smart’ with the ‘grid’ with M2M technology BY JEFF DIXON, Freewave Technologies As the world becomes increasingly connected, the integration of smart devices and tools, such as sensors, process control devices, smart meters, and security cameras have increased the need for...
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...
In a significant move that underscores the growing demand for reliable and sustainable energy to power the expanding digital infrastructure, the Federal Energy Regulatory Commission (FERC) has approved an interconnection agreement between Talen Energy, Amazon Web Services (AWS), and Exelon. This...
The evolving demands of modern power grids necessitate the adoption of advanced technologies that can provide enhanced efficiency, reliability, and flexibility. Smart transformers are at the forefront of this technological revolution, offering a range of capabilities that significantly improve the...
The electric power industry is increasingly having to evaluate the growing penetration of distributed energy resources (DER). New sets of challenges exist for planning and operating the grid, especially with the distribution systems in which these new resources must be integrated. Now electric...
Increasing the hosting capacity of distributed generation in power distribution systems is identified as key low-carbon solution to help meet the aggressive greenhouse gas emission reduction targets in the energy sector. The deployment of distributed generation technologies is creating a paradigm...
NEURAL GRID TAKES SMART GRID INTO THE CLOUD The Neural Grid represents more than Smart Grid v2.0—much more. Today, the smart grid implies the legacy mechanical power transmission and distribution (T&D) networks enhanced by pockets of automation, connectivity, and centralized IT systems. The...
