According to media reports, recently Southern California Edison sought approval from the state Public Utilities Commission to replace 800 miles of aging underground cable, after concluding that cable failures were the leading cause of outages that could be prevented. In 1928, the Federal Trade Commission launched a comprehensive inquiry into the entire electric power industry, as abuses mounted, from financial pyramid schemes and the stock market speculation of the "Roaring Twenties." The investigations culminated in the 1935 passage of President Franklin Roosevelt's Public Utility Holding Company Act, which forced the breakup of many holding companies, and several of American Electric Power's holdings were divested. Journal of the Franklin Institute of the State of Pennsylvania 119: 490-494. (quote from p. While what became American Electric Power still maintained operations stretching from Virginia to Michigan, each state regulated its utility companies, defined the level of reliability to be maintained, and, in return, assured each company a modest return on investment. The national impact of declining reliability and quality, they estimate, is in excess of $50 billion.
Black & Veatch reports that although utilities currently spend more than $18 billion on local distribution systems, most of that is to string new wire to new housing developments (which will likely come to an end soon, along with the housing boom), and that an additional $8-10 billion per year is needed to replace obsolete and corroded equipment. The California blackouts cost in excess of $1 billion each. But "consumer advocates" opposed the utility's request to recoup the $145 million cost of replacement, on the grounds that the utility's records were not adequate to ensure the worst cables would be replaced first. It doesn't cost much more, but it gives the telco the opportunity to upsell you to a second line. It is also the case that entire regions, in particular the West and East Coasts, have so much congestion on their transmission lines, that they cannot import the power they need. Tin, gold, and silver are much less prone to oxidation than copper, which may lengthen wire life, and makes soldering easier. The engineers, who have among them, more than five decades of experience in the electrical utility industry, insist that "new transmission lines will not by themselves improve reliability. They may increase transfer capacities, and hence improve commercial use of the grid," but will not necessarily improve performance of the system.
In some cases, mostly mobile and manufactured homes, the NID may actually be mounted to the telephone pole at the street or your property line, and the overhead or underground connection to your house is also your problem. Industry-wide, there is agreement that weaknesses due to the age of the underground distribution cable have been exacerbated by the way the system is run in today's deregulated world. In addition to chronological age, overheating of equipment that is caused by heavy electricity use and is repeatedly stressed will age faster, and is more likely to fail suddenly. Companies that have been buying up transmission capacity will make a bundle, in the process. The 1978 law required the traditional utility companies to purchase power from these expensive "alternative" power sources. But it is not the size of the concentration of electrical power capacity that is creating the chaos; it is the "free market" concentration of economic power, which allows a handful of companies to maximize profits by buying up power lines, looting infrastructure through disinvestment, and setting prices to maximize profits. After the mid-1970s Middle East War and orchestrated "oil crisis," which quadrupled prices, the Carter Administration proposed, and Congress passed, the 1978 Public Utility Regulatory Policies Act, which promoted "conservation," and poured billions of wasted Federal dollars into the development of small non-utility power generators, using "non-traditional" sources of power, such as biofuels, solar, and wind energy.
This insane turning back the clock to pre-industrial 19th Century methods was reinforced by attacks on nuclear power, reversing the policy of massive additions of new nuclear plants then underway. For the past three decades, financial warfare, and attacks by anti-technology fanatics and free-market ideologues, have created the "perfect storm" that has left the U.S. Among the group of passengers no one listened more attentively to Dr. Jackson's recital than a New York artist, named Samuel Finley Breece Morse, who was returning from a three years' residence in Europe, whither he had gone for improvement in his art. Red, yellow and blue color are the three phases of the electrical circuit. It's actually fairly intentional that the electrical specifications in the system are all soft targets. Metric Mind, a well-respected supplier of AC electric car motors drive systems for electric cars, says that for general drivability, the AC system is far superior to the DC system. Not a problem for AC electric car motors, which have no brushes. Now, we have entered the sanctum of the inside plant, and a different department of the company. The Department of Energy was tasked with identifying the cause. In 1992, the National Energy Policy Act created another class of non-regulated electricity producers, known as exempt wholesale generators.
