LA Blackout Roundup

A little less than 24 hours after wide swaths of Los Angeles were left without power yesterday, a number of folks are asking pointed questions about the hows and whys of the blackout, which was apparently caused by worker error:
A mistake on a single bundle of wires Monday cascaded into a major blackout in and around Los Angeles, inconveniencing millions of people and renewing questions about the vulnerability of the region's power system...

The mistake rippled through the electrical grid, threatening to overload another transmission station and two electrical generating plants: the Scattergood generating station south of Los Angeles International Airport and the Haynes generating station near Long Beach.

The DWP shut down the generating facilities to avoid damage, sharply reducing the amount of power available to the city. That caused blackouts in neighborhoods across the city, with heavy concentrations in parts of the San Fernando Valley, South Los Angeles and the downtown area. All of Burbank's 52,000 customers and half of Glendale's 80,000 also lost power. Both cities' electrical systems are linked to the DWP.
With the power out, the job of explaining the outage fell to LADWP's Ron Deaton:
The veteran civil servant stood calmly in front of the DWP headquarters on Bunker Hill in downtown Los Angeles with a giant map of the power grid, trying to explain why it was actually good news that so much of the city was without power.

"The system was doing what it was supposed to do," Deaton told a television reporter, explaining that power was switched off to protect the system from being greatly damaged.

"It's better to shut it down than to burn out the whole system," he said.
Christopher Swope has some thoughts on Deaton's performance. Here's a map of how the outage cascaded throughout the area. When the power goes out, many of the modern conveniences we rely on, like broadband Internet access, fall to the wayside:
Another tool of modern life — high-speed Internet connections — was knocked out in some parts of the city because of the outage. Patti Rockenwegner, a spokesperson for Comcast, which provides cable and broadband Internet service to about 500,000 customers in Southern California, said some customers in Hollywood and South Los Angeles lost service for about 40 minutes when the outage tripped fuses.
As was reported elsewhere, Los Angeles-based Web hosting provider Dreamhost was knocked offline for several hours, taking a number of bloggers with it.

Here's a map of how the outage cascaded throughout the area.

With the power out, a number of LA-based refineries were forced to burn off petroleum products:
The controlled fires, or flares, were visible for miles and triggered air quality alerts in neighborhoods surrounding the refineries. They prompted a small number of emergency room visits from residents who complained of illnesses they said were caused by the fires. While commuters and residents of communities such as Wilmington are familiar with the spectacle, the burn-offs rarely occur in such numbers and at the same time...

Gasoline is produced under great pressure and heat. When refineries lose power, that pressure needs to be released. The petroleum product is sent up tall stacks, where it is burned off by the stack-top flares, causing flames and heavy smoke. The burn-off is a safety mechanism that prevents chemicals from spreading through the refinery, officials said.
The paper has set up a message board and asked LA residents to share their experiences -- some more interesting than others. For a more humorous take on the outage, check out Bridget Johnson.

Bill Quick is annoyed:
I can almost write this story in my sleep. It hasn't changed in a generation. Some piddling switch or transformer or relay blows a gasket, and ever-widening cascades of failure eventually destroy the power to thousands of square miles and millions of people.

The fact is, our national power grid is an antiquated mess. And much of our other infrastructure, from roads and rails to power, transport, and shipping systems, is a rickety joke. Yet what do we spend money on?
A good question. The fact is, America has been underspending on energy infrastructure for a long, long time.

An Ohio School Board Is Working to Save Nuclear Plants

Ohio faces a decision soon about its two nuclear reactors, Davis-Besse and Perry, and on Wednesday, neighbors of one of those plants issued a cry for help. The reactors’ problem is that the price of electricity they sell on the high-voltage grid is depressed, mostly because of a surplus of natural gas. And the reactors do not get any revenue for the other benefits they provide. Some of those benefits are regional – emissions-free electricity, reliability with months of fuel on-site, and diversity in case of problems or price spikes with gas or coal, state and federal payroll taxes, and national economic stimulus as the plants buy fuel, supplies and services. Some of the benefits are highly localized, including employment and property taxes. One locality is already feeling the pinch: Oak Harbor on Lake Erie, home to Davis-Besse. The town has a middle school in a building that is 106 years old, and an elementary school from the 1950s, and on May 2 was scheduled to have a referendu

Why Ex-Im Bank Board Nominations Will Turn the Page on a Dysfunctional Chapter in Washington

In our present era of political discord, could Washington agree to support an agency that creates thousands of American jobs by enabling U.S. companies of all sizes to compete in foreign markets? What if that agency generated nearly billions of dollars more in revenue than the cost of its operations and returned that money – $7 billion over the past two decades – to U.S. taxpayers? In fact, that agency, the Export-Import Bank of the United States (Ex-Im Bank), was reauthorized by a large majority of Congress in 2015. To be sure, the matter was not without controversy. A bipartisan House coalition resorted to a rarely-used parliamentary maneuver in order to force a vote. But when Congress voted, Ex-Im Bank won a supermajority in the House and a large majority in the Senate. For almost two years, however, Ex-Im Bank has been unable to function fully because a single Senate committee chairman prevented the confirmation of nominees to its Board of Directors. Without a quorum

NEI Praises Connecticut Action in Support of Nuclear Energy

Earlier this week, Connecticut Gov. Dannel P. Malloy signed SB-1501 into law, legislation that puts nuclear energy on an equal footing with other non-emitting sources of energy in the state’s electricity marketplace. “Gov. Malloy and the state legislature deserve praise for their decision to support Dominion’s Millstone Power Station and the 1,500 Connecticut residents who work there," said NEI President and CEO Maria Korsnick. "By opening the door to Millstone having equal access to auctions open to other non-emitting sources of electricity, the state will help preserve $1.5 billion in economic activity, grid resiliency and reliability, and clean air that all residents of the state can enjoy," Korsnick said. Millstone Power Station Korsnick continued, "Connecticut is the third state to re-balance its electricity marketplace, joining New York and Illinois, which took their own legislative paths to preserving nuclear power plants in 2016. Now attention should
