On the seventh anniversary of Hurricane Katrina, Gulf Coast residents watched as Category 1 Hurricane Isaac bore down on the New Orleans region, evoking memories of the costliest U.S. hurricane disaster on record. On Aug.
As the use of renewable power, electric vehicles (EVs) and the smart grid become more widespread and integrated, one challenge also becomes more apparent: storage. Thankfully, the experts are on it. This summer, the U.S.
Much of the smart grid’s strength lies in its use of wireless technology to improve monitoring, information flow and efficiency. As powerful as that combination may be, a couple of California utilities have taken it to a new low. That is to say they have taken it underground.
For the electrical contractor (EC), finding a role in the smart grid shouldn’t be a matter of “wait and see.” Now is the time to prepare for this growing opportunity. If your work involves building automation and lighting controls, you are well on your way.
With the Institute of Electric Efficiency reporting more than 36 million smart meters installed from 2007 through May 2012 and a target of 65 million by 2015, it appears that smart meters are here to stay.
On most distribution networks (except maybe in rural areas), the voltage levels typically reduce to a couple of percentage points from nominal when the sun rises, people wake up and they start using more electricity. Conversely, as the sun sets, the voltage creeps back up, and by 10 p.m.
One of renewable energy sources’ biggest challenges is the intermittency of power generation. Finding a way to store power for later use helps make renewables more practical for tying into the grid where demand does not always coincide with the wind or the rising sun.
Two years ago, Verizon Communications’ 30,000 facilities worldwide consumed more than 9 billion kilowatt-hours of electricity annually. Energy costs to operate and cool Verizon’s communications equipment accounted for a significant portion of its total corporate energy bill.
Infiniti Research Limited’s report, “Global Smart Energy Meter Market 2010–2014,” forecasts that market will reach $19.5 billion in 2014. Key factors contributing to market growth are initiatives from regulatory authorities and home area networking connectivity technology.
Despite recent reports of coal-fired power plants shutting down and states moving away from coal as a generation source, it seems the nation’s dominant source of fuel for generating electricity will be around for years to come.
As the electric grid develops to incorporate renewable generation, more robust transmission and smart meters, utilities are beginning to work on the final segment of delivery by automating their distribution networks.
All the recent hype and investment in energy efficiency, renewable power and new technology won’t amount to much without the proper upgrades to our energy infrastructure. Thankfully, the trend points to rapid growth in this dimension, too.
Internet protocol (IP) is increasingly described as a revolutionary force. This is a well-deserved description, as the world has adopted the Web and the underlying IP superstructure for communication, entertainment, news, shopping, gaming and, now, building automation systems (BAS).
With distributed sources, there can be a mix of grid-connected and grid-independent sources. For example, take the combination of photovoltaic sources in this figure. Ideally, there should be a mix of centralized and decentralized (distributed) generators.
According to a report conducted by The Perryman Group, an economic and financial analysis firm based in Waco, Texas, the construction and operation of Exelon’s proposed nuclear power facility in Southeast Texas would not just increase energy reliability.
