Smart Substations and Their Role in the Evolving Smart Grid

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...

Transforming power grids for an efficient future

With a fast-growing global population and increasing levels of industrialization, demand for electricity is expected to soar 60 percent between now and 2040. That means power grids will be called on to transmit more power, more efficiently. And to do so, they’ll have to adapt to an evolving...

Grids Become Highly Vulnerable

Increasingly violent weather, probably caused by global warming, is increasingly taking down electricity distribution lines and poles and cyberattacks are increasingly taking out electricity, apparently just as trials for major terrorism of this sort. Little wonder that the price of grid...

How AMI Can Improve Grid Reliability and Outage Response

Leveraging AMI to improve grid reliability and outage response

BY TIM WOLF, Itron

Getting a handle on overall grid reliability and outage trends for the entire U.S. can be challenging. Despite generally high reliability numbers, power outages are occurring more frequently and the U.S. Department of Energy estimates that outages cost the American economy as much $150 billion per year. Unfortunately, outages are affecting more people and lasting longer than just a decade ago. These...
