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.
Energy projects currently underway across the United states reflect several trends—new construction in the alternative-energy sector and renovation at traditional power plants to update aging infrastructure.
Charlottesville has been selected as the first city in Virginia and one of the first in the nation to benefit from smart grid technology that will make the delivery of electricity more efficient and less costly while improving customer service.
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.
Although the hyperbole of the recent elections is past us, one of the buzzwords that gained momentum in the process was the term “smart grid.” I agree with those in the electric utility industry who take exception to such a concept, with all the implications associated with it, including that the c
Electrical contractors traditionally have a lot to say about how their distributors could make their lives easier. Problems range from not getting all the parts in one shipment to delivery delays to emergency service failures—all of which cost time and money.
An owner approaches you not only for the electrical wiring of a new building, but also the highest-tech structured cabling system available for security, networking and e-access, including Voice over Internet Protocol (VoIP).
As customers increasingly demand more complex and technologically advanced voice/data/video (VDV) systems for their facilities, electrical contractors must rely more than ever on their distributor partners to supply the value-added services that will strengthen their competitive edge.
A survey states that electrical contractors buy over 90 percent of electrical materials.Cooperation between these parties is required to get these materials to a project. Electrical contractors determine the type and brand of about half the materials purchased.
The 1978 Public Utility Regulatory Act encouraged on-site generation to use the energy normally wasted in large remote power plants for hot water and steam. Now the idea is emerging again with a new name: distributed generation. It could be the solution to power shortages and rolling blackouts.
