Advocating for a Comprehensive Energy Bill

Advocating for a Comprehensive Energy Bill

Christine Coogle, Editor and Social Media Manager, NEMA This week, I joined the NEMA government relations team and representatives from several NEMA companies on a visit to Capitol Hill to meet with congressional staff involved in the House-Senate energy bill conference committee. Our object was to advocate for the swift development and passage of a comprehensive energy bill with a number of specific provisions important to our members. Both the House of Representatives and the Senate Read more [...]
Level the Market for All Emerging Sources of Electricity

Level the Market for All Emerging Sources of Electricity

This piece was originally published in the August 2016 issue of electroindustry. Congressman Paul Tonko (D-NY) I had the opportunity to discuss the importance of energy storage and battery systems at the White House Summit on Scaling Renewable Energy and Storage with Smart Markets on June 16. Participants included leading utilities, state energy officials, energy storage developers, and demand response providers. At the summit, the Obama administration announced approximately $1 billion Read more [...]
NEMA Section Takes Lead in Energy Storage

NEMA Section Takes Lead in Energy Storage

This piece was originally published in the July 2016 issue of electroindustry. Steve Griffith, PMP, Industry Director, NEMA The application and use of energy storage systems (ESSs) has grown dramatically in grid-scale and building-based systems. These systems are capable of doing much more beyond storing power when there is less demand and helping smooth out supply-and-demand challenges. As a case in point, entities that are considering the application and use of ESSs need accurate, Read more [...]

Energy Storage Systems to Recover Braking Energy on SEPTA Network

This piece was originally published in the April 2016 issue of ei, the magazine of the electroindustry. By Daniel Simounet, Director, Transportation Market Segment, North America, ABB Under a recent contract negotiated between ABB and Constellation, a subsidiary of Exelon Corporation, ABB will engineer, manufacture, and commission seven energy storage systems (ESSs) with lithium-ion battery storage from Saft America for the Southeastern Pennsylvania Transportation Authority (SEPTA) train Read more [...]
The Role Energy Storage Plays in a High-Renewable-Energy Future

The Role Energy Storage Plays in a High-Renewable-Energy Future

This piece was originally published in the March 2016 issue of ei, the magazine of the electroindustry. By Garrett Fitzgerald, PhD, Senior Associate, Rocky Mountain Institute With Tesla announcing a home battery that uses electricity generated from solar panels, the German company Sonnenbatterie entering the U.S. market, and massive grid-scale storage projects popping up in Hawaii and California, 2015 was the year of the battery. It also happened to be the year of the first global Read more [...]
A Tale of Wind and Water

A Tale of Wind and Water

In early 2012 NEMA produced a return on investment (ROI) whitepaper for Smart Grid; a document that was very well-received at the NARUC annual meeting in Washington, D.C. that year.  In the whitepaper we cited a number of examples, one of which was a plan filed by the Duluth-based Minnesota Power company to connect a wind farm in North Dakota to a hydroelectric site in Manitoba, Canada.  An article about this project recently appeared in the electronic version of Renew Grid magazine http://www.renew-grid.com/e107_plugins/content/content.php?content.10444.

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 [...]
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 [...]
What are the driving forces behind expansion of LVDC beyond Data Center Applications?

What are the driving forces behind expansion of LVDC beyond Data Center Applications?

The ability to directly link between photovoltaics or energy storage mechanisms and direct current (DC) rated utilization equipment is an attractive option to avoid the potential energy losses and heat generation associated with power conversion from DC-to-AC-to-DC.  Many pieces of utilization equipment, particularly IT, home electronics and appliances, and office equipment are actually operated by DC supplied from individual power supplies that convert the AC current from the utility or building Read more [...]
Comparing apples and oranges and energy storage

Comparing apples and oranges and energy storage

As more and more grid energy storage projects are planned, how do you select the best technology for the need, or even begin to report and compare performance?  Comparing pumped hydro, compressed air, sodium sulfur batteries, flow batteries, lead acid batteries, lithium ion batteries, flywheels, and capacitors is akin to comparing apples to oranges to pears to kumquats to….you get the point. Ambiguity in measuring performance in energy storage could result in slowing down adoption of Read more [...]
