• Old-fashioned way to protect high-voltage substations

    There are about 45,000 substations in the United States, but far fewer high-voltage substations like the one attacked last April in Metcalf. California. Americans could see what the loss of just one important power substation can have when, in 2003, a failure in one such substation knocked out power to fifty million people in the United States and Canada for days. Illinois-based IDT says that since Biblical times, the method of thick-walled fortifications to halt manned and artillery attacks remains the best technology for protecting lives and important assets. The company says that its METALITH, a several-feet-thick prefabricated steel barrier structure filled with sand, would offer the best protection to vulnerable power substations. “While most of the electrical industry has been focused on the threat of cyber-terrorism, the San Jose [Metcalf is near San Jose] attack points to the need for physical protection of strategic power grid assets as well,” says Tom Carlton, IDT’s CEO.

  • Former FERC chair calls for mandatory security standards for high-voltage substations

    Jon Wellinghoff, the former chairman of the Federal Energy Regulatory Commission(FERC), is leading a crusade to improve physical security around the nation’s electrical grid. Following a 16 April 2013 sniper attack on a San Jose, California substation he is urging Congress to give federal agencies the authority to demand improved security around electrical substations. “This isn’t about this substation or this organized attack,” Wellinghoff said of the California incident. “This is more about the larger issue of physical security of these high-voltage substations nationwide and the need to ensure that some defensive measures start to be put in place.”

  • Lawmakers want mandatory security standards for national grid

    Lawmakers have urged the imposition of federal security standards on grid operator in order to protect the U.S. national electric grid from attack. The new push follows stories, first reported in the Wall Street Journal reported last Wednesday, about a 16 April 2013sniper attack which disabled seventeen transformer in a San Jose, California substation for twenty-seven days, causing about $16 million in damage. Federal cybersecurity standards for protecting the grid are in place and mandated, but rules for protecting physical sites such as transformers and substations are voluntary.

  • Children living near overhead power lines do not have greater risk of leukemia

    Children who live near overhead power lines in early life do not have a greater risk of developing childhood leukemia, researchers find. The study included nearly 16,500 children who were diagnosed with leukemia in Britain between 1962 and 2008. An earlier study using information on childhood leukemia diagnosed between 1962 and 1995 had suggested that there was an elevated risk for children born within 600 meters of overhead power lines. This new study includes children diagnosed up until 2008, and finds that children born after the 1980s do not have an increased risk.

  • Attack on California power station heightens concerns about grid security

    Security experts are concerned that last year’s unsolved attack on an electrical-power substation in San Jose, California, is but a prologue to similar attacks which, if executed simultaneously and in a coordinated fashion against several such substations, could cripple the U.S. power grid. The transformers at the substation, vital for regional power distribution, were shot at by several gunmen and disabled for twenty-seven days. What is especially worrisome, security exert note, is that the attack appeared to have been carried out by people with some training, although the FBI said the agency does not think it was the act of terrorists.

  • Aging grid cannot keep up with growing demand for electricity

    The demand for electricity in the United States increased by around 20 percent from 1999 to 2009, but transmission capacity only increased by around 7 percent in that time. From 2000 to 2004, there were 140 instances of power outages which each affected 50,000 or more consumers. This number increased to 303 from 2005 to 2009. Between 2010 and 2012, there were 226 such outages. The average age of a power plant is 30-years old, and around 75 percent of America’s power lines are 25-years old. Economists estimate that these power outages cost the country more than $70 billion in annual economic loss.

  • Making the U.S. grid sturdier, smarter, and more secure to thwart blackouts

    In August 2003, fifty million customers throughout the northeastern United States and southeastern Canada lost power for up to two days. More than ten years later, the U.S. electric power system continues to be challenged. In the United States, 149 power outages affecting at least 50,000 customers occurred between 2000 and 2004, a number which grew to 349 between 2005 and 2009. In 2012, the prolonged power outages in New York and New Jersey caused by Hurricane Sandy once again demonstrated the system’s vulnerability. A broad, multidisciplinary effort by Georgia Tech researchers aims to revolutionize the delivery of electricity, advance the smart grid, thwart blackouts, integrate renewable energy sources, and secure utilities from cyberattacks.

  • The world likely to face more frequent, and more severe, blackouts

    U.S. household electricity usage increased by 1,300 percent between 1940 and 2001. In the last few decades, air conditioning has been the greatest factor in increased electrical consumption, and one of the greatest sources of systematic strain, with considerably more blackouts occurring in the summer months than during winter. The electricity used to fuel America’s air conditioning is currently of a similar volume to the U.S. entire energy consumption in the 1950s. A new study reveals that today’s occasional blackouts are dress rehearsals for the future, when they will occur with greater frequency and increased severity. Power cuts will become more regular around the globe as electrical supply becomes increasingly vulnerable and demand for technology continues to grow at an unprecedented rate.

  • Minimizing power grid disruptions from wind power

    Researchers have found that an increase in the use of wind power generation can make the power grid more fragile and susceptible to disruptions. The researchers, however, did not just identify the problem — they have also devised a technique for coordinating wind power generation and energy storage in order to minimize the potential for such power disruptions.

  • National grid in mock power emergency drill today and tomorrow

    North American power companies will participate in a mock power emergency scenario today and tomorrow (13-14 November) to test their ability to respond to physical or cyberattacks that may lead to widespread power outages and long term blackouts. The exercise, known as GridEx II, is the second emergency response exercise conducted by North American Electric Reliability Corporation (NERC) intended to task North American electric utility companies with reviewing their security and crisis response strategies.

  • NIST seeks public comments on updated smart-grid cybersecurity guidelines

    The National Institute of Standards and Technology (NIST) is requesting public comments on the first revision to its guidelines for secure implementation of “smart grid” technology. The draft document, NIST Interagency Report (IR) 7628 Revision 1: Guidelines for Smart Grid Cybersecurity, is the first update to NISTIR 7628 since its initial publication in September 2010.

  • NIST releases Preliminary Cybersecurity Framework

    The National Institute of Standards and Technology (NIST) on Tuesday released its Preliminary Cybersecurity Framework to help critical infrastructure owners and operators reduce cybersecurity risks in industries such as power generation, transportation, and telecommunications. In the coming days, NIST will open a 45-day public comment period on the Preliminary Framework and plans to release the official framework in February 2014.

  • Bolstering national grid resilience as extreme weather events intensify

    Between 2003 and 2012, an estimated 679 widespread power outages in the United States occurred due to severe weather. A recent Congressional Research Service study estimates the inflation-adjusted cost of weather-related outages at $25 to $70 billion annually. A new White House report says that grid resilience is increasingly important as climate change increases the frequency and intensity of severe weather.

  • SkySweeper robot inspects power lines easily, cheaply

    Mechanical engineers invented a robot designed to scoot along utility lines, searching for damage and other problems that require repairs. Made of off-the-shelf electronics and plastic parts printed on an inexpensive 3D printer, the SkySweeper prototype could be scaled up for less than $1,000, making it significantly more economical than the two models of robots currently used to inspect power lines.
