Reduced air emissions due to wind power: More

December 4, 2009

Michael Giberson

Kent Hawkins has a further post at Master Resource examining the effects of wind power on overall emissions produced in a power system.

In the post Hawkins examines the Michael Milligan et al, article, “Wind Power Myths Debunked,” appearing in the most recent IEEE Power and Energy Magazine (an article mentioned in comments I made here pointing out Hawkins’s earlier post). The “debunking” of Milligan et al seeks to portray many issues raised with respect to wind power as less important than wind power critics assert.

Hawkins’s response aims to debunk the debunking.  If you are inclined to rely on the Milligan et al article, you ought to consider the objections raised by Hawkins seriously.

Thankful for lax security at Turkey Point?

December 4, 2009

Michael Giberson

The Miami Herald reports that early Thanksgiving morning smugglers dropped 30-plus Cuban migrants off on the property of the Turkey Point nuclear power plant, 25 miles south of Miami.  Apparently the group remained undetected on the property for about 8 hours, at which time the group called the plant’s control room seeking a second helping of mashed potatoes and gravy help. (The plant has call boxes on the property for the use of maintenance workers.)

The Herald said:

A spokesman for Florida Power & Light said Friday that the group was six miles from the reactors, and the power plant in southern Miami-Dade County “was not affected in any way.”

But the utility, which boasts of tight security in the area, did not address why its security personnel apparently did not become aware of the Cubans’ presence on Turkey Point for up to eight hours.

Power market design example

December 4, 2009

Michael Giberson

Ever wonder what a RTO power market design looks like?  Here is one view, in the form of the 106-page “Mid Level Description” of the Southwest Power Pool market currently under development.  (Note that the link is to a 1.4 MB zip file which contains the “SPP Future Markets Design/Energy and Operating Reserve Markets and Transmission Congestion Rights Markets/Mid-Level Description,” and an accompanying memo from the SPP Market Working Group which describes a bit of the process that went into producing the document.)

For a taste of the document, here’s a paragraph on “Block Demand Response Resources” (BDR) from page 3.9:

In the RTBM, if the BDR is committed and dispatched in the DA Market or RUC, the BDR Minimum Economic Capacity Operating Limit will be increased to match the dispatched amount and only Spinning Reserve will be allowed to clear above minimum output if the BDR is a Spin Qualified Resource.  Spinning Reserve clearing will be based upon submitted Ramp-Rate Up curve for BDR, the submitted Spinning Reserve Offer and the BDR’s Maximum Economic Capacity Operating Limit.

Based on a quick, haphazard scan through the document, the paragraph is of approximately median readability compared to the rest of the text.  Note: RTBM = Real Time Balancing Market, RUC = Reliability Unit Commitment, and DA = Day Ahead.

Easterly on the civil war in development economics

December 4, 2009

Michael Giberson

William Easterly writes, “Few people outside academia realize how badly Randomized Evaluation has polarized academic development economists for and against.”

That claim seems reasonable enough. I’d bet few people outside academia know what randomized evaluation is. Frankly, I’d bet you could survey economists on the floor of the upcoming American Economic Association meetings in Atlanta and, for non-development specialist, find that fewer than 50 percent “realize how badly Randomized Evaluation has polarized academic development economists.”

Easterly raises the point as a way to introduce a conference and now edited book volume — he helped organize the conference and edit the book — which brought together the fors and againsts for dialog.

Shale gas as a game changer: A view from the UK

December 3, 2009

Michael Giberson

Production of natural gas from shale has dramatically changed the U.S. energy resource picture, and although experience elsewhere is limited* it is increasingly obvious that this not just a North American story. Nick Grealy, at No Hot Air, considers the implications for the UK:

North American shale gas already has a significant indirect effect on UK, European and World Gas Prices. Even in the unlikely event that there are no UK shale plays, the UK, due to exposure to international market forces, will be in the position of benefiting from an acquired immunity which will provide low prices for natural gas for many years to come. Some observers believe that volatility will also ebb and that prices will be both low and stable.

A pair of recent No Hot Air posts emphasize the fallout from the changing gas market: “Gas v. Coal,” and “Gas as the new UK baseload.”

HT to FT:Energy Source, which provides complementary remarks: “LNG glut driving a UK baseload power shift.”

*Experience in the United States is limited, too, as extensive shale gas development began less than a decade ago. (That brief background is one reason significant uncertainty remains about the reliability of the new conventional wisdom about gas resources, at least in the minds of a few analysts.  However, as one gas developer explained, the industry actually has years and years of experience drilling in and around shale formations.  It isn’t as if the resource is unknown; it is just that it was not previously accessible and economic to develop.)

Hamilton on oil prices and the recession

December 2, 2009

Michael Giberson

James Hamilton, “Will rising oil prices derail the recovery?“:

I have no doubt that the problems with financial markets were a bigger factor than oil prices in the striking collapse in output in 2008:Q4 and 2009:Q1. The other approaches to measuring the contribution of oil to the downturn surveyed in my Brookings paper would estimate a smaller contribution of oil to the downturn than suggested by the figure above. On the other hand, all of the approaches surveyed in that paper suggest that oil made a material contribution to the initial downturn, and it seems hard to deny that that the severity of the financial crisis was exacerbated by the fact that the U.S. had spent three quarters in recession prior to the failure of Lehman in September 2008.

Hamilton then considers the concern that rising oil prices will dampen or destroy prospects for economic recovery.

Will Wilkinson, at The Week, writes about “The perils of political correctness–left and right.”  How we think about what is and is not socially acceptable can, in some cases, get people killed.

How to build a nuclear power plant without captive ratepayers

December 1, 2009

Michael Giberson

Jonathon Fahey, at Forbes.com, explains “How NRG Energy Wants to Revive Nuclear Industry.”

In the early part of the decade proponents talked breathlessly of a nuclear renaissance in the U.S. Natural gas prices were high, electricity demand was rising, and it seemed that carbon emissions would soon be either taxed or limited. In 2005 Congress passed an energy bill that provided loan guarantees for construction of new nukes on top of tax credits for power produced by the first few new reactors. Utilities fell over themselves planning new nuclear plants– nearly 40 proposals were drawn up.

Four years later the country is where it was a decade ago, at 104 operating nuclear plants (producing 20% of its electric energy). Natural gas prices crashed, making nukes look comparatively more expensive. Carbon remains untaxed and uncapped, and the recession ate into electricity demand, pushing the need for new plants further into the future. Credit markets also dried up, while the pool of government loan guarantees, $18.5 billion, was smaller than the industry hoped for, enough probably for only three plants.

Now, while 17 nuclear projects are still active, only a half-dozen plant proposals are moving at full speed, led by the four projects that are finalists for federal loan guarantees….

The story notes that NRG is an independent power producer, not a regulated utility, and so “doesn’t have a pool of captive ratepayers (as Southern and Scana do) who will pay for construction or cost overruns.”  But that isn’t to say that NRG isn’t looking for help whereever they hope to find it.  The NRG plant is among the finalists for federal load guarantees and, if built, may qualify for up to $125 million a year in tax credits during each of the first eight years of production.  NRG is partnering with the municipal utility in San Antonio for the nuclear plant expansion, and has lined up (or is looking for) additional financial partners.

The NRG strategy is either “how to build a nuclear plant in this day and age” (in the words of the director of NRG’s nuclear ventures) or just a matter of “finding a series of suckers to take the risk off his hands” (in the words of a nuclear power critic).

Green cloud computing in Finland

December 1, 2009

Lynne Kiesling

Check out this cool new data center plan — locate the servers under a cathedral and use the waste heat to warm the cathedral and the neighboring buildings! This is an established system called district heating, which uses a network of steam or hot water pipes to heat distributed buildings.
