How Much Wind and Solar Capacity Would a Billion Dollars Buy?

Those cost overruns so far on the new nukes? How much solar and wind could that money buy?

John Hanger wrote on his Facts of the Day today, $913 Million Construction Overrun Hits Georgia New Nukes: How Much Gas, Wind, Solar Capacity Would That Buy?

Comparing the Vogtle initial $913 million cost overrun to the capital costs of gas, wind, and solar plants show just how big these cost overruns can be. The Vogtle $913 million cost overrun by itself could have paid for approximately 1,000 megawatts of natural gas generation; 450 megawatts of wind power; and 330 megawatts of solar power.

Don’t forget that’s just the first cost overruns on those nukes. When the current Plant Vogtle nukes were built, there were supposed to be four at a cost of $660 million; only two were built, at a cost of $8.87 billion. That’s a cost overrun of 1300%. How much solar and wind could $8 billion buy?

Moreover, gas, wind, and solar generation could be up and running in 3-years or less from the first day to the last day of development, as opposed to the 10 years or more needed to build a nuclear plant.

Austin Energy’s new 30 MW solar farm, for example, approved beginning of 2009, opened end of 2011, and cost less than originally projected.

Oh, and solar doesn’t leak radioactive tritium like Plant Hatch and won’t get shut down two days after an NRC clean bill of health like Plant Vogtle.

Cost overruns already starting for Georgia Power’s new nukes

Remember how Georgia Power customers get to pay for cost overruns on the new nukes? Well, the overruns have already started.

JoAnn Merrigan wrote for WSAV 15 May 2012, Environmental Groups: Plant Vogtle Reactors Almost One Billion Over Budget,

A group of nine national environmental groups says that the two new nuclear reactors being built at Plant Vogtle (near Waynesboro in eastern Georgia) are over budget by up to $1 billion dollars. The opponents say Georgia Power’s share of the cost overruns is currently $400 million and that may cost ratepayers as well as taxpayers who are guranteeing loans in the billions of dollars.

The nine environmental groups, Friends of the Earth, Southern Alliance for Clean Energy, Blue Ridge Environmental Defense League, Center for a Sustainable Coast, Citizens Allied for Safe Energy, Georgia Women’s Action for New Directions, NC WARN, Nuclear Information and Resource Service, and Nuclear Watch South, are also suing:

Powering North Carolina with wind, sun, and water

Here's some hard evidence of FERC Chairman Jon Wellinghoff's assertion back in 2009 that baseload is outdated, we don't need any new nukes or coal, because we can get all the new power we need from sun and wind. This study from North Carolina goes further: we don't need coal or nukes at all.

John Blackburn, Ph.D. wrote a report March 2010, Matching Utility Loads with Solar and Wind Power in North Carolina: Dealing with Intermittent Electricity Sources,

Takoma Park, Maryland, and Durham, North Carolina, March 4, 2010: Solar and wind power can supply the vast majority of North Carolina's electricity needs, according to a major report released today. Combined with generation from hydroelectric and other renewable sources, such as landfill gas, only six percent of electricity would have to be purchased from outside the system or produced at conventional plants.

Hourly Power Generation and Load for a sample day in July

"Even though the wind does not blow nor the sun shine all the time, careful management, readily available storage and other renewable sources, can produce nearly all the electricity North Carolinians consume," explained Dr. John Blackburn, the study's author. Dr. Blackburn is Professor Emeritus of Economics and former Chancellor at Duke University.

"Critics of renewable power point out that solar and wind sources are intermittent," Dr. Blackburn continued. "The truth is that solar and wind are complementary in North Carolina. Wind speeds are usually higher at night than in the daytime. They also blow faster in winter than summer. Solar generation, on the other hand, takes place in the daytime. Sunlight is only half as strong in winter as in summertime. Drawing wind power from different areas — the coast, mountains, the sounds or the ocean — reduces variations in generation. Using wind and solar in tandem is even more reliable. Together, they can generate three-fourths of the state's electricity. When hydroelectric and other renewable sources are added, the gap to be filled is surprisingly small. Only six percent of North Carolina's electricity would have to come from conventional power plants or from other systems."

Six percent is a small number. That means most coal plants could be shut down, and no nukes are needed.

FERC and energy demand response

Beyond a smart grid to mix and match the supply solar and wind to get rid of any need for new coal or nuclear plants, as FERC Chairman Jon Wellinghoff recommended three years ago, FERC also has plans to mix and match demand. Energy customers can volunteer to shut off their air conditioners or clothes dryers automatically if there’s not enough supply. This could facilitate adding solar power, by basically acknowledging that it may not always supply a fixed capacity.

Todd Griset wrote for law firm PretiFlaherty 23 April 2012, FERC seeks demand response standards,

Demand response, an innovative strategy to ensuring the integrity of electric grids, is growing in popularity, prompting federal regulators to consider standardizing how demand response performance is measured.

Managing an electric grid entails ensuring a constant balance between electric generation and customer demand for electricity. As customer demand rises, grid operators have traditionally called on more and more generating units. In most markets, grid operators dispatch the lowest-cost units first to keep overall costs down. As a result, generating units needed to meet peak demand tend to be more expensive than baseload generation. Many peaking units also emit more pollutants per unit of energy than baseload units.

In a demand response program, customers can volunteer to be available to reduce their load during times of peak demand. When done right, this reduction in customer demand can play much the same role as dispatching additional generation, but at a lower cost in dollars and environmental impacts. Energy efficiency resources can also play a similar role.

The U.S. Congress and the Federal Energy Regulatory Commission have both recognized that demand response can be a decentralized, crowd-sourced alternative to peaking power plants. Utilities and regional transmission organizations across the nation are implementing demand response programs.

Across the nation…. How about it, Georgia Power, and Georgia EMCs? How are your demand response programs coming?

FERC Chairman: baseload outdated; no new nukes needed; go sun and wind

Power companies’ main stated objection to solar or wind is that they are not “capacity” or “baseload” generation because sometimes the sun does not shine and the wind does not blow. And those utilities are required by various state, regional Energy Regulatory Commissions right up to the Federal Energy Regulatory Commission (FERC) to supply capacity or baseload power. That’s their main excuse for coal and nuclear plants. Well, the Chairman of FERC thinks we may not need baseload, nor any new coal nor nuclear plants, either.

Noelle Straub and Peter Behr wrote for ScientificAmerican 22 April 2009, Will the U.S. Ever Need to Build Another Coal or Nuclear Power Plant? The new chairman of the Federal Energy Regulatory Commission doesn’t think so

No new nuclear or coal plants may ever be needed in the United States, the chairman of the Federal Energy Regulatory Commission said today.

“We may not need any, ever,” Jon Wellinghoff told reporters at a U.S. Energy Association forum.

So what will we need?

Ben Hill Coal Plant Cancelled

Ben Hill Coal Plant was cancelled today by Power4Georgians (P4G). Losing Cobb EMC funding plus new air pollution regulations finally had a good effect.

According to SACE PR today, Proposed Ben Hill Coal Plant Cancelled in Georgia: Power4Georgians in Tenuous Position on Plant Washington After Legal Agreement

Clean air advocates and environmental groups won a victory today when Power4Georgians (P4G), the only company trying to develop expensive new coal plants in Georgia, agreed to comply with critical new safeguards against mercury pollution. The company also agreed to cancel the proposed Ben Hill coal-fired power plant and invest $5 million in energy efficiency and renewable projects. The Sierra Club, the Fall Line Alliance for a Clean Environment (FACE), Southern Alliance for Clean Energy (SACE), and the Ogeechee Riverkeeper, represented by GreenLaw and the Southern Environmental Law Center, successfully challenged the permit for Plant Washington issued by the Georgia Environmental Protection Division, and the settlement agreement is pending approval by each group. If built, Power4Georgians’ Plant Washington will have to meet the much more protective emission standards for mercury and other air toxins.

The longterm implications are even better:

Community’s need for public transportation, bike lanes, and walking —Heather Evans @ LCC 10 November 2011

Heather Evans provided a petition with more than 200 signatures, and told Thursday’s Valdosta City Council meeting she got requests frequently while working in community service for something to be done about non-automobile transportation. She presented a variety of evidence.
Ideally, I’d like to see bike lanes all over town. But if I had to pick one to start with, St. Augustine would be my choice. I choose this road because it also needs to have a completed sidewalk segment. I can’t tell you how many people including myself have been endangered while using this portion of road.

George Rhynes took this video and remarked:

WOW! Valdosta-Lowndes County is now being seen as a real metro city and citizens are asking questions to their elected officials. WOW! The old control, suppress, and abate is apparently unacceptable in 2011 as we get ready for the 2012 Presidential election.

Waste Not, Want Not —Michael Noll

VDT LTE today. -jsq
We can only prosper as a society if we work together. Despite the differences we might have, we share so much more in common. Yet it seems that we prefer to fall into separate camps, that we seek to view issues in black and white, and that we like to belong to those who have “got it all figured out”. Just pick your side (liberal, conservative) and you “know” who got it all wrong.

I have been humbled by the wide-ranging support WACE received to stop a biomass plant that was once considered a done deal. In the end what mattered was the realization by people across all ages, racial and ideological lines that we want to breathe clean air, and that we don’t want to waste millions of tax dollars on a project that will lead to increases in respiratory illnesses, heart diseases, and cancer. Thus the people spoke up, and with the help of elected representatives and the Industrial Authority “no biomass” became the consensus.

In the last couple of months I noticed another issue many agree on.
