Since over 80% of electrical maintenance testing involves evaluating insulation integrity, the first and most important test done on electrical equipment is an Insulation Resistance (Meg) Test. This is because electrical insulation begins to age as soon as it’s manufactured and aging causes deterioration in the performance of the insulation. Harsh operating environments will also cause further deterioration, especially where the electrical insulation is exposed to extreme operating temperatures, moisture, and chemical contamination. As a...
The traditional utility business model of selling electricity from large-scale thermal power plants and expanding grids to meet rising demand historically has supported strong balance sheets. With this financial strength, utility retained earnings served as the primary financing source for the...
Study shows growth from now to 2020 Aging infrastructure and increased demand for power has amplified the demand for transmission towers. In their latest report ,“The Global Market for Electricity Towers and Poles 2014 to 2020”, StatPlan Energy, specialists in the electricity sector,...
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...
Sargent & Lundy has provided comprehensive engineering, development, permitting, high-level consulting, construction management, and commissioning services for electric power generation and power delivery projects worldwide—approximately 2,000 clients in nearly 100 countries—since...
A Smart substation digitizes protection and control, enabling utilities to detect faults faster, manage DER volatility, and reduce outage risk. The payoff depends on architecture, cybersecurity, and edge analytics, not just new relays. The shift toward smart substations is inseparable from broader...
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...
