National Grid has unveiled plans for the future home of its Sustainability Hub, a 2,200 square-foot facility centrally located within the company’s smart grid pilot area in Worcester, Massachusetts....More
With land-use and permitting issues becoming more complex and expensive, cable might be close to being price-competitive with overhead transmission. That would particularly apply in highly populated areas where right of way is a premium (as is visual impact). Do you see that happening in the U.S.? Europe? Doesn't the recent storm damage make cable more attractive financially?...More
An analytical report released last month by the U.S. Department of Energy found that as of March 2012 the total invested value of the $2.96 billion to support Smart Grid projects generated at least $6.8 billion in total economic output....More
The reliable supply of electrical energy is a backbone of the modern economy. Its ability to operate safely and reliably mainly depends on high-voltage switchgear. The continuing demand for higher transmission power and lower transmission losses per line favors the use of ultrahigh-voltage (UHV) levels – applying rated voltages of 800 kV, 1,100 kV and 1,200 kV....More
Poor power quality is becoming an increasing cause of concern for both the users and the suppliers of electrical power. Consequences of poor power quality include reduced efficiency in the generation, transport and use of electrical power and an increase in system breakdowns. System reliability decreases and operational costs increase. The introduction of renewable power sources into the grid adds further challenges with respect to load demand management and voltage stability. ABB is a pioneer in, and offers a complete portfolio of, products that address a wide variety of power quality problems in all voltage categories....More
Given their inherent flexibility and relative ease to implement, microgrids offer an interesting alternative to expansion of the existing power infrastructure in a variety of applications. Learn more fascinating aspects of microgrids, including how to achieve a higher penetration of renewable power.
