First Ice-Free Arctic Day Could Come Before 2030

The Arctic is undergoing rapid changes, and a new study suggests that the first ice-free day in the Arctic Ocean may come sooner than previously expected—before 2030. This alarming possibility underscores the accelerated pace of climate change and its potential to significantly alter the Earth's climate system.

The Arctic has long been a barometer for global warming, with temperatures in the region rising at more than twice the global average. This phenomenon, known as "Arctic amplification,"...

FERC Proposes Ride-Through Standards for Renewables

The Federal Energy Regulatory Commission (FERC) is seeking public input on proposed "ride-through" reliability standards for inverter-based resources (IBRs), including wind, solar, and battery systems. These standards aim to ensure that IBRs can maintain operation during grid disturbances, such as...

Facing Wildfire? Choose Toughened Glass Insulators

Insulators under fire, what are we talking about?

  • A line directly in the fire is considered as lost
  • A line near the heat of a fire can be saved
  • What is the condition of insulators on a line nearby a fire?

Reliability of insulators during or after a fire is a key consideration for T&D line design or refurbishment.
One must evaluate the risk of a line drop in the proximity of a fire as well as the possibility for a catastrophic failure afterwards resulting from a degraded insulator.

Substation Focused on Environmental Design

One of the important trends in design of new overhead lines over the past 20 years has been development of structures and designs that are less obtrusive and more pleasing visually. Much the same process has also been going on at substations. For example, even 25 years ago, efforts had already been...
