Research by an international team led by SLAC National Accelerator Laboratory and Stanford scientists has uncovered a new, unpredicted behavior in a copper oxide material that becomes superconducting – conducting electricity without any loss – at relatively high temperatures....More
A new study finds that distributed generation, energy efficiency, storage, microgrids, and other innovations add resilience and dynamism to the grid, but do not obviate the need for major expansion of the high-voltage, bulk power system....More
The Federal Energy Regulatory Commission last week acted to promote broader regional transmission planning in the U.S. Western Interconnection by clarifying that an Order No. 1000 regional transmission planning process may conduct transmission planning on behalf of non-public utility transmission providers,...More
You tell us: What are the biggest causes of outages in the United States for a) distribution b) transmission? Are things getting better or worse? How does the U.S. reliability compare to other countries?...More
To help enhance the reliability of its electric system, Potomac Edison crews have replaced or repaired about 1,000 wooden utility poles so far this year as part of the company's annual inspection program....More
In the early 1990s, I led a team at one of the power industry’s large equipment manufacturers to look into aging utility infrastructures and determine what it meant for both the future of our industry and the company....More
A majority of T&D professionals reported that their companies are addressing aging assets (65%), followed by the use of smart meters feeding outage management systems (42%), according to a new survey sponsored by Burns & McDonnell....More
FirstEnergy Corp. has completed a new transmission line and substation in Armstrong County, Pennsylvania, to help enhance service reliability for West Penn Power customers in Allegheny, Armstrong, Butler and Westmoreland counties.
The Federal Energy Regulatory Commission has adopted a new reliability standard to mitigate the impacts of geomagnetic disturbances that can have potentially severe, widespread effects on reliable operation of the nation’s bulk-power system....More
Through the U.S. Department of Energy’s Smart Grid Demonstration Program (SGDP), the New York Power Authority (NYPA) and Oncor Electric Delivery Company (Oncor) demonstrated dynamic line rating (DLR) technologies to increase the efficient use of the existing transmission network, mitigate transmission congestion, and develop best practices for applying DLR systems....More
I notice that some some manufacturers are offering flexible iron rather than wood or steel. What's the advantage? Are we moving toward higher wind speed standards for structural strength and is this primarily due to storms?...More
Chances are, you are already well aware of the onslaught of coal plant shutdowns due to environmental concerns, regulations and the capital cost of upgrading aging assets. With systems primarily built around coal plants, especially in the East, how does a power plant maintain grid stability in light of these shutdowns? Learn how FACTS devices, such as static VAR compensators, provide overall grid stability and voltage control, saving utilities time and money.
