Climate change adversely affecting U.S. power grid

Yes, and moving away from baseload coal, nukes, and natural gas and towards distributed solar and wind power will help with that, both directly by making the grid more resilient, and indirectly by slowing climate change.

Clare Foran wrote for NationalJournal 12 August 2013, Climate Change Is Threatening the Power Grid: So says the White House, in a new report that recommends strengthening the grid.

Just days away from the 10-year anniversary of the worst power outage in U.S. history, the White House and the Energy Department released a report on Monday evaluating the resiliency of the nation’s electric grid and recommending steps to prevent future blackouts.

The report called storms and severe weather “the leading cause of power outages in the United States,” and warned against the steep cost of weather-related damage to the electric grid. It put the price tag for electrical failures caused by inclement weather at between $18 billion and $33 billion annually, and noted that costs have increased in recent years, jumping from a range of $14 billion to $26 billion in 2003 to $27 billion to $52 billion in 2012. Storms exceeding a billion dollars in damages (electrical and otherwise) have also become more frequent in the past decade, as the chart below shows.

Well, Entergy’s Arkansas Nuclear 1 (ANO1) is still down more than four months after a fatal accident (hey, look at that; Continue reading

Pilgrim nuke down because of cold, heat, leak: when does it ever run?

Down in January, February, April, May, running low March and June, and now likely to go down because of summer heat, under what conditions does Entergy’s Pilgrim nuke near Boston, MA like to run? Entergy also couldn’t keep the power on during the Super Bowl and still has Arkansas Nuclear 1 down since a fatal accident in March. To be fair, many nukes can’t handle heat. Remind me, why are we building more of them?

PLYMOUTH — The ongoing heat wave could force Pilgrim Nuclear Power Station to shut down, as soaring temperatures continue to warm the Cape Cod Bay waters that the plant relies on to cool key safety systems.

Arkansas Nuclear 1 still down since fatal accident in March

Apparently we still don’t know why this happened:

At approximately 7:50am on Sunday, March 31, 2013, a 600-ton generator stator fell onto the turbine deck and then about 30 feet to the train bay floor as was being lifted out of the Unit 1 turbine building at the Arkansas Nuclear One plant. One worker was killed and four others injured when the load fell.

The NRC reviewed U.S. nuclear plant experience with lifting loads with cranes between 1968 and 2002. The NRC reported that about two load drops per year happened during this period with ten incidents causing deaths. The NRC’s review concluded that there had been only three very heavy load drops (defined as a load weighing more than 30 tons). ANO-1 makes four.

While accidents can also happen with wind turbines or even installing solar panels on rooftops, a single solar or wind accident doesn’t Continue reading
