Yokohama Smart City Project Demonstrates Experimental Social Infrastructure

Yokohama Smart City Project Demonstrates Experimental Social Infrastructure

By Ryan Franks, Program Manager, NEMA Today the White House is hosting an Earthquake Resilience Summit to “promote adoption of an earthquake early warning system in the United States.” Electrical manufacturers recognize the vital importance of smart infrastructure—and smart rebuilding—to mitigate the effects of natural disasters and ensure quicker and more effective recovery. This article, published in September 2013, details a smart infrastructure project undertaken in Yokohama, Japan, Read more [...]
Go straight until you reach the energy storage tower, then turn left.

Go straight until you reach the energy storage tower, then turn left.

Explaining what energy storage is can be difficult sometimes.  Leave explaining the benefits for another day.  If you store air in a balloon, it expands.  If you store boxes in a warehouse, the shelves get full.  But, if you store energy, for most mediums you usually still have a paneled or enclosed box still sitting there, unchanged to any of the five senses.  Maybe a fan is blowing harder, maybe. The American electricity grid is remarkable and unique.  It forms one Read more [...]
Argonne Observations

Argonne Observations

Dear Mr. President, We at NEMA were delighted when you visited Argonne National Laboratory to raise the curtain on initiatives aimed at delivering a “clean and security energy future” to the nation. One part of the two-part strategy you unveiled was music to our ears:  making our current energy resources go farther across the economy. The other part was expanding domestic energy sources, mostly in renewables. You spoke of an “Energy Efficiency Race to the Top challenge” Read more [...]
Rebuilding "smart" after Sandy with new NEMA publication

Rebuilding "smart" after Sandy with new NEMA publication

Superstorm Sandy highlighted the fragile nature of our nation's electric grid. One thing is clear: our grid needs some updating. In an effort to assist federal, state, and local policymakers with solutions to harden the nation’s electric grid, improve its resiliency to withstand severe weather, and improve energy efficiency, NEMA published Storm Reconstruction: Rebuild Smart. As communities continue to rebuild after Sandy, incorporating "smart" technologies into the grid can Read more [...]
Light in the Darkness

Light in the Darkness

It’s been a week since power has been restored to San Diego after a massive “operator error”-induced blackout. In a sign of just how far we as a nation still have to go in achieving a Smart Grid, not only were grid operators unable to choke off the outage before it grew into a major blackout, but operators (as well as the media and even Congress) are still scratching their heads about just how this localized problem spread so far and so rapidly. California’s ISO announced Read more [...]
LVDC and Harmonic Currents

LVDC and Harmonic Currents

NEMA, UL and NFPA sponsored a very successful workshop in Crystal City, VA during April on the topic of Low-Voltage Direct Current.  There were 17 presenters and over 140 attendees at this state-of-the-industry event.  LVDC is of interest because establishing a direct connection between distributed power generators (especially photovoltaics) plus energy storage devices (mostly batteries) and the many electronic products that operate on LVDC allows elminiation of Read more [...]
