Plus without careful orchestration by the BPA sudden wind can overload the NW Power Grid and send operators into panic attacks trying to balance the load. Don't tie their generating windmills to the Oregon power grid, so power surges with be their problem and not ours. There is absolutely no reason to use the scenic tourist areas of Oregon to generate power for Californians. Who ever thought that we would have something as charming as the Dutch windmills here in United States. In fact, bird deaths were found to be 30 percent higher than previous estimates given by the U.S.
I worked on some contract projects for the California Department of Fish and Game several years ago, and one of my colleagues was a wildlife biologist who specialized in ornithology. The bird and bat population impacts (and additional factors such as the noise and light mentioned above) are one reason a lot of environmentalists aren't quite so keen on wind power as other forms of renewables.
A systematically designed and executed terrorist attack could cause disruptions considerably more widespread and of much longer duration than the largest power system disruptions experienced to date.
The reliable operation of the power grid is complex and demanding for two fundamental reasons. Electricity moves at close to the speed of light (186,000 miles per second) and is not economically storable in large quantities, so electricity must be produced the instant it is used. Electric systems are not designed to withstand or quickly recover from damage inflicted simultaneously on multiple components. As many as half of the 400,000 electric utility workers will be eligible to retire in the next 5 to 10 years.
One reason there aren’t enough employees is that they were fired due to industry restructuring, pressures from Wall Street and regulators, mergers and acquisitions, and the evolution of wholesale markets. This substantial downsizing has made electric utility jobs far less secure and therefore stressful. Much of the document deals with how to solve these issues, how to protect facilities, the desperate need for engineers to replace the 50% of retiring workers, and how to get private businesses, industries, and essential services to buy back-up generation. The researchers conclude it would cost too much money to protect every installation, and too much money to buy all the spare parts needed. The threat to any given utility is modest, so to spread the risk, there is a program to get utilities to share in the cost of buying spare parts collectively, especially transformers. I think the ruthless nature of capitalism will prevent an effective collective spare parts collaboration, because each privately owned entity is selfishly motivated to make profits for its executives and shareholders only. Natural gas power plants are fed by natural gas pipelines that use electricity to keep the natural gas flowing.
Microprocessors can’t be made if the electric grid isn’t up or delivers low-quality electricity. Hangzhou is being treated by China as a "new energy vehicle demonstration" pilot city, putting the city at the vanguard of the promotion of electric vehicles in China. Implementation of the large-scale electric vehicle leasing program is expected to begin in August 2012, and to be completed in 2013. The electric rental cars, supplied by Kandi Technologies, are positioned as a means of green transportation for Hangzhou residents, to provide for their driving needs within the region. Kandi Technologies is the only EV manufacturer out the 10 companies involved in the project. The battery packs will additionally be used for grid stabilization using Vehicle-to-grid (V2G) technology.
The idea behind V2G is that "grid stabilization" efforts can be helped along if there are large scale battery packs attached to the electricity grid. The Hangzhou project neatly side-steps one of the resistance factors to V2G efforts in the past. In August, Kandi Technologies will be showcasing electric cars and "smart parking technology" at the 2012 China International Green Vehicle Industry Expo in Hangzhou. Kandi Technologies manufactures a range of small electric vehicles, including a Go-Kart, an ATV, and a couple variations on the small vehicle shown here. This project is just one example of how China is moving aggressively to develop electric vehicle, smart grid, and clean energy technologies.

An interview with Beniot Jacob, BMW's Head of Design, where he discusses the design of the i3. This electricity infrastructure operations center is designed for research to help guard against threats ranging from natural disasters to international attack, and to make the grid more flexible, reliable and efficient. The complex and piecemeal grid system that delivers electricity across the nation is largely a 20th century structure, she said, and it won’t meet many of the demands or the opportunities of the 21st century. Inside the new building is an electricity infrastructure operations center designed for research to help guard against those threats and make the grid more flexible, reliable and efficient. The center streams live grid data into two control rooms, allowing software and related tools to be tested to see how they perform without risking disruption of electricity delivery on the grid. Operations can be mimicked to see the results of slight changes to the grid, such as adding more wind power, from the source of production through transmission to delivery to individual buildings. The data-filled, electronic screens that line the front walls of the control rooms are cool, said engineer Karen Studarus during a tour of the center Wednesday.


Researchers can see the grid in more detail than ever before, enabling advancements critical to achieving a reliable and secure power system, said Steven Ashby, director of the Department of Energy national lab in Richland. PNNL has developed systems, such as GridLAB-D, a first-of-its-kind analysis and simulation tool that allows users to see in extremely high resolution how making changes to one part of the grid affects other parts of the system.
The work done at the center will provide benefits from helping lower utility bills for Northwest consumers to increasing the use of renewable energy to leave the world a better place for our children and grandchildren, said Sen.
And in true PNNL fashion, it is transitioning its research out of the laboratory into the real world, she said.
GridLAB-D is open source software, available for utilities worldwide to use to understand electricity distribution down to the customer level. The approach is intended to speed development and industry adoption for widespread modernization of the grid. IncSys was one of PNNL’s first industry partners to use the new electricity infrastructure operations center.
The electrical industry is undergoing a transformation and its challenges have never been greater or more important, said Elliot Mainzer, chief executive of the Bonneville Power Administration.
The new Systems Engineering Building also houses PNNL’s Building Operations Control Center. It can look at the entire PNNL campus, including its approximately 35 buildings, and analyze more than 50,000 data points a day, said sustainability engineer Shan Belew. On a bank of monitors hanging the length of the room, he can watch data ranging from which buildings are using the most energy to room-by-room operations of a climate control system that adapts to the absence of workers. PNNL is working toward a 30 percent energy reduction on its campus between 2003 and this year. Elsewhere in the building is the Power Electronics Laboratory, large enough for electric vehicles to be driven in for research on charging, energy storage and controls.
The 24,000-square-foot building on Horn Rapids Road was designed by Meier Architecture Engineering of Kennewick and built by DGR*Grant of Richland. Even as the world of transportation technology rushes forward, two of the Golden State's largest cities are preaching evolution rather than revolution. The company's subsidiary Sidewalk Labs may or may not be meeting with Alphabet leadership soon to discuss such a project.
The Federal Highway Administration is calling on state and local transportation agencies to work together on a new data-reporting initiative.
Our weekly newsletter delivers breaking stories to help you solve the challenges faced in building economically and socially robust communities. If the USA ever gets off its duff and builds a national power grid, wind power can provide a major portion of our energy needs. The current boom in natural gas production has made wind power less economically feasible, but only a fool thinks that's going to last forever. I drive that stretch of I-84 all the time and it is appalling to see the landscape ruined by wind turbines when they just as well could have been placed out of sight. In the early 2000s, he did a multi-year study for PG&E on the impact of the Altamont Pass Wind Farm (one the first in the nation, built in the early 1980s) on raptors, and the results were pretty discouraging. All those wind turbines are on private land, and the ranchers are collecting a steady income from leasing the site.
Somebody has to be thinking about the hundreds of millions of people that will contribute to population growth in this century. Since those disruptions have entailed economic impacts approaching 10 billion dollars, it appears possible that terrorist attacks could lead to costs of hundreds of billions of dollars—that is, perhaps as much as a few percent of the U.S. First, electricity moves at close to the speed of light (186,000 miles per second, or 297,600 kilometers per second) and is not economically storable in large quantities.
Such an attack could be carried out by knowledgeable attackers with little risk of detection. There are 5,800 major power plants connected by 450,000 miles of high-voltage transmission lines spanning thousands of miles to unguarded facilities protected only by a chain-link fence.
The grid depends on complex systems of sensors and automated and manual controls, all of which are tied together through communication systems, so instead of a physical assault; terrorists can cause blackouts by spoofing, jamming, or sending improper signals.
Commandos with special training could mount a far stronger attack than even the most sophisticated terrorist group.
Department of State lists over 42 international terrorist groups operating around the world today using rocket propelled grenades, mortars, and small arms.
This loss of critical skills and training new workers is a significant problem for the electric utility industry, and likely to make nation’s electric power system will less reliable and more vulnerable to external threats, including terrorist intrusion and disruption from natural disasters. Many utility engineers report a substantial broadening of work assignments without the necessary time to become “experts” in their new areas of responsibility. This knowledge is often not documented, and frequently it is known only to a very few people.
So when the electricity goes out, the oil will stop flowing to refineries, and there will be no fuel for ships, trucks, barges, cars, or airplanes. So even if a business or home has had the foresight to buy back-up generators, they won’t be able to get gas or diesel fuel because most gas stations don’t have backup power. But the real magic is the access to live data for research and its analysis on high-performance computers. Volttron, a PNNL system that allows appliances and other devices to communicate with each other to prioritize power needs and coordinate delivery, also is open source and publicly available.
An adjacent outdoor area provides space to connect to even larger assets, such as utility-scale energy storage units and commercial-grade rooftop air conditioners. 20 years from now we will be running out of natural gas again, but the wind will still be blowing.


Everyone realizes they need to be close to existing transmission lines, which by the way, are out of sight. The 845-megawatt project uses over 300 turbines and spans across 30 square miles of Gilliam and Morrow Counties in north-central Oregon. That said, the Columbia Gorge is a scenic reserve and you will never see a wind turbine there. It is a network of substations, transmission lines, distribution lines, and less visible automatic and human controls that operate the system, as well as an intricate web of computers and communication systems that tie everything together.
A large and coordinated attack by terrorists could leave the electric power system in a large region of the country disabled many months or, in absolute worst cases, several years, because substation and generator step-up transformers are vulnerable to attack from within and from outside the substation, are very large, difficult to move, custom-built, and can take over a year to replace. This makes the electric grid hard to protect, and so it can be severely damaged by a small number of well-informed attackers.
It’s hard, if not impossible, to defend substations from explosions, bullets, or other projectiles fired from a distance.
They cover more functions and technical areas at less depth, now that so many engineers have been fired.
Terrorists are also likely to take out natural gas transmission lines when they attack the electric system as well. Over 10% of electric demand is controlled by microprocessors,by 2020 it’ll be over 30% (EPRI, 2003). It serves as a living laboratory to demonstrate the cutting-edge technology developed at PNNL, Studarus said.
It's time for America to quit stumbling from crisis to crisis and to do some serious energy planning. You would also know that your cheap electricity comes from the BPA, which is running short on Columbia River water to generate power. Since 1998 when the region's first wind farm, Vansycle Ridge, came on line, Oregon has seen more giant turbines enter the landscape. When it was completed in September 2012, it became the largest wind farm in Oregon, and the second largest in the world.
Several years ago my undergrad college's alumni magazine had a story about a study conducted by a professor there that explained why birds' eyesight doesn't register the whirling blades, regardless of the way they're painted or treated in any other way to discourage collisions. The plateau east of there, Walla Walla County and Umatilla County, is just wasteland that takes 5 acres to feed one cow.
If large, extended outages were to occur during times of extreme weather, they could also result in hundreds or even thousands of deaths due to heat stress or extended exposure to extreme cold.
Second, pending the development of affordable control devices, the flow of AC electricity cannot be controlled like a liquid or gas by opening or closing a valve in a pipe, or switched like calls over a long-distance telephone network. We no longer make them – getting one from another country can take a while because they’re in such high demand across the developing world. A hostile country might take this approach if it were unable or unwilling to declare war but wanted to take some military action against the United States. Most attacks so far have come from local groups bent on damaging or destabilizing established ruling power structures.
This in turn has led to few students wanting to go into power engineering as a career, most universities have dropped power engineering, only 12 colleges have this degree now.
Clements, Free Lunch: How the Wealthiest Americans Enrich Themselves at Government Expense (and Stick You with the Bill) by David Cay Johnston, or When Corporations Rule the World by David C Korten. Natural gas pipelines used to use the natural gas flowing through them to power the continued flow of natural gas. They too are vulnerable to climate change (rising sea level, heat buckled rails, etc.), failing infrastructure, and declining coal supplies.
The electric power system was designed to serve analog electric loads and doesn’t always provide the quality power required by digital manufacturing assembly lines and information systems.
But in the long term, it's clear that solar power is the future of energy production, as much in India as anywhere else. When the wind blows, they don't have to run the water turbines, which conserves water during periods of low flow, like right now. Around 2,500 attacks have occurred over the past 10 years, 528 against substations, 2,539 against transmission towers. Further complications arise if terrorist attacks involve chemical, radio nuclear, or biological agents.
Trains deliver 70% of coal, and a lot of it: over 1 in 5 railcars are carrying coal – over 40% of the weight trains haul. A nearly imperceptible 1-second variation in power quality due to transients, harmonics, and voltage surges and sags at a semiconductor-fabrication plant can ruin an entire 30-hour batch of microprocessors and sometimes the manufacturing equipment, and take several days or more for a fabrication plant to recover and resume production again. The vulnerability of electric power systems can have serious national security implications.
In World War II, Germany’s highly centralized electric system was not attacked until late in the war. The National Academy of Engineering called the grid the world’s largest integrated machine and a central part of the greatest engineering achievement of the 20th century. German officials commented after the war that ‘‘The war would have finished 2 years earlier if the Allies had bombed our power plants.
