Supply the United States with renewable energy: A stand-by-State road map
на 12:37 AM Saturday, March 01, 2014Back in the year 2011 Stanford professor Mark Jacobsen presented, which require that, and followed that with an analysis of how to achieve it in the State of New York. (Our coverage was by the way, is by far the most commented story in recent memory.) Now he extends his analysis in all 50 US States, laying out a resource roadmap, as each of them meet 100 percent of their energy needs (electricity, heating and transport) could through renewable sources of energy to 2050 - except nuclear, ethanol and other biofuels. Keep in mind that none of these calculations are aligned to optimize use of renewable energies for the least cost mix 100 percent. Levelized electricity costs of this mixture renewable energy by the year 2030 expected 11 cents/kWh (including local transfer), fossil energy with additional costs for health and climate will be compared with 20-25 cents / kWh.
Its latest results include two more deep dives for New York, show how they all new energy capacity powered by renewable energy (see the definition above) by 2020, 2030 converted 80-85% of the existing energy and could reach 100 percent by the year 2050. He takes California, percentage renewable energy footprint achieve a 100 with the following portfolio: 55 percent solar (distributed and large-scale, including many CSP), 35 percent wind (on - and offshore), geothermal energy, 5 percent and 4 percent hydroelectric power, a large contribution of energy efficiency. (Mixing with solar wind and combines that with hydro, CSP with storage, largely to smooth frequency issues, he concludes.) Ultimately, that is a net 178,000 permanent jobs avoid $131 billion in annual health-care costs and pay the 631 GW newly installed capacity within six years.
In the U.S. State of Washington, Jacobson et al. calculate how a 2050 fully renewable energy mix: 43 percent wind, 28 percent solar PV, 26 percent hydro, 2% geothermal and half a percent each wave and tidal. New capacity expansions by 137 GW $228 billion cost would be paid but in 13 years. Note that Washington has an abundance of hydroelectric power and has thus an advantage for integrated storage energy consumption match; No new Hydro are necessary (more on that later), but he assumes capacity of existing hydroelectric power stations is updated to improve efficiency.

Overall, the methods were quite similar: "look at the footprints and areas and how many devices of any kind of that we need," Jacobson explained. Compared to his previous calculations, these new findings extend the time frame, until 2050, instead of only by 2030. Also more are energy buildout to account for installations, like for example an extensive wind since its 2011 study and updated the latest insight into job creation.
He is also posted by the addition of mortality on the basis of air quality data for each State look back calculations, the three years in each district and illustrate how air pollution and its direct connection to mortality reduce renewable energy. He goes into the health-care costs due to air pollution around three per cent of the GDP of the United States says (quick math: the U.S. GDP is about $17 trillion, so the $500 billion in health-care costs). Address could quantify at the subnational level with concrete figures such as renewable energy proves and reduce "a significant burden for the company."
The smoothest pathway, relatively speaking, to 100 percent renewable energy achieve what States have? The key, he says, knocking and improvement of existing large hydro, without coming to any new partner. "Each State with Hydro is inclined, this makes it easier", he says. United States Washington would lead this Pack because of the abundant hydropower resources - up to 30 percent of what they would - need plus a small but growing amount of wind and solar energy. He also finds that the State policy and leadership, "very supporting to change things." Other States, which could use the best Hydro include Idaho and New York. The growing influence of wind energy in some States (Iowa, South Dakota) also helps.
On the other hand it will be so easy a journey into the Southeastern States, to tap the less renewable energy and more about the interconnection. (Note that his estimates restrict non-States, receive renewable energies outside its borders, this brings things like Canadian Hydro in some Northern States.)
Perhaps the biggest takeaway Jacobson updates, is that roughly speaking none of this is new. "We have no new technology to invent it," he says. "We need to get more efficient from the perspective of costs."

Europe divided on security of supply, such as renewable energies is growing
на 7:30 AM Thursday, February 13, 2014Europe’s power market relied on intermittent wind and solar output for a record 7.4 percent of generation in 2012, a share poised to reach 18 percent by 2020, according to Energy Brainpool GmbH & Co. KG., a Berlin-based consultant. The renewable energy boom cut profitable hours at coal and gas-fired plants and IHS Inc. estimates that as much as 60 percent of the region’s gas capacity isn’t covering costs and may be at risk of closure by 2016.
“Capacity mechanisms are popping up like mushrooms all over Europe,” David Viduna, head of long-term origination at Prague-based utility CEZ AS, said in an interview in Vienna on Jan. 29. “The point is that all those efforts need to be harmonized” because payments in one country affect the competitiveness of plants in neighboring countries, he said.
Preventing Blackouts
Nations are seeking to prevent blackouts as utilities plan the biggest-ever wave of shutdowns of unprofitable power plants. As much as 110 gigawatts of gas-fired capacity probably will shut in the next three years, according to IHS, a researcher based in Englewood, Colorado. One gigawatt is enough to power about 2 million European homes.
U.K. utilities from Centrica Plc to SSE Plc will be able to bid in an auction this year to offer backup power plants from 2018 at the lowest possible cost, according to the Department for Energy and Climate Change.
“We need more generation,” Michael Fallon, U.K.’s energy minister, said Jan. 21 in an interview. “We’re losing a fifth of our capacity over the next 10 years.”
Even with 58 nuclear reactors designed to operate 24 hours a day, France doesn’t have enough capacity to meet peak winter demand. Europe’s second-biggest power user may have to import almost 3,600 megawatts during cold snaps this winter, according to RTE, Electricite de France SA’s grid unit. There’s a “moderate risk of supply shortages,” the network manager said in a Nov. 7 report.
Guaranteeing Supply
“France is convinced of the need” to take action to prevent blackouts, Robert Durdilly, president of the Union Francaise de l’Electricite, which represents power producers and distributors, said Jan. 29 in an interview.
From 2016, suppliers without enough capacity to meet the highest peak in demand from their customers must purchase certificates from generators guaranteeing backup supply, according to Commission de Regulation de l’Energie, the Paris- based regulator.
Germany, Europe’s biggest market, is paying plants deemed essential for power supply stability, including EON SE’s Irsching gas-fired plant in Bavaria, on an individual basis. Details have not yet been agreed to for a longer-term measure, according to a text adopted at a meeting of Chancellor Angela Merkel’s cabinet in Meseberg that ended Jan. 23.
Gas-fired plants such as Irsching can’t operate for enough hours to cover their costs, Georg Oppermann, an EON spokesman in Dusseldorf, Germany, said by e-mail.
“This is why we believe that plants which are needed for the security of the power system should be rewarded adequately,” he said.
Increase Trading
Nations should instead ensure security of supply by building more cross-border connections and increase trading with neighbors, according to the commission.
One of the pillars of the European Union is a single market where people, goods, services and capital move freely between its 28 nations. The region’s plan for a joint energy market by the end of 2014 will save as much as 70 billion euros ($94 billion) a year by 2030, according to the commission. Coupling, a step on the way to achieving a single market, may save consumers as much as 4 billion euros a year.
Europe began linking day-ahead markets in November 2006 as France, Belgium and the Netherlands integrated allocation of transmission capacity on cables and power trading. Germany and Luxembourg joined in November 2010.
The link-up of next-day electricity trading from the U.K. to Finland is intended to make power flow more easily across borders to where it is most needed.
First Auction
Prices in the first next-day power auction held today by network operators and energy exchanges across countries that account for 75 percent of Europe’s electricity supply ranged from 35.98 euros a megawatt-hour in Germany to the equivalent of 53.88 euros in the U.K.
“A strong, interconnected electricity transmission grid is critical” to creating a Europe-wide energy market and ensuring security of supply, Ethel Horan, spokeswoman for Brussels-based grid group Entso-e, said by e-mail.
“If we allow national ways of fixing markets with capacity mechanisms, it undermines the internal market,” said Klaus- Dieter Borchardt, a director for internal market in the energy department of the regulator in Brussels.
Capacity mechanisms could have “unfavorable effects” on competition, French regulator CRE said in a report last year. If a plant in one country receives payments, it may be able to sell power at cheaper rates than generators in neighboring countries, CEZ’s Viduna said.
Spanish Plant
A typical idle 500-megawatt gas plant in Spain, where generators have been able to earn capacity payments since 2007, receives about 7.3 million euros a year, according to Endesa SA, the Madrid-based utility. The number isn’t based on an actual plant.
Tennet Holding BV, one of four German high-voltage grid managers, will pay a “middle double-digit million-euro sum” a year to the Irsching 4 and 5 power plants to prevent them closing, EON said in May.
Capacity mechanisms are designed to pay the most flexible plants to act as backup when renewable output drops. A gas-fed plant with the latest technology can produce power within minutes, while coal-fed stations can take as much as six hours to reach full capacity.
Germany’s five-fold increase in renewable energy in the decade through 2012 intensified the need for gas-fired plants. Wind and solar accounted for as much as 49 percent of Germany’s power on Dec. 23, falling to 4 percent two days later, data from the European Energy Exchange compiled by Bloomberg show.
Further Declines
Profit at gas plants plunged as German power prices slumped. The benchmark year-ahead contract in Europe’s largest economy fell 29 percent since 2010 and traded at 36.55 euros a megawatt-hour today, broker data show. Prices may slide as much as 10 euros with a capacity mechanism because of the reduced risk of supply disruption, according to Tom Tindall, a director at IHS in London.
Gas-fed plants have been losing money since 2012 and will remain unprofitable through 2018, according to data compiled by Bloomberg. Power plants in Germany lose 20.73 euros for every megawatt-hour of power they generate, a gauge known as the clean-spark spread, a calculation based on year-ahead power price, fuel and emissions costs, according to data on Bloomberg.
Capacity mechanisms may cost consumers as much as 20 percent of the value of wholesale power markets, according to the commission. That’s 13.2 billion euros a year across Germany, France and the U.K., the bloc’s three largest markets, based on average prices and 2012 consumption.
Household Bills
That would add to the 28 percent price increase in the six years through 2013, according to Eurostat data. German residential bills are more than twice the amount that utilities pay to deliver the power, according to Berlin-based lobby group BDEW, even as demand last year fell to the lowest in a decade.
Economic output in the 18-nation euro region probably rose 0.4 percent in the three months through December after sliding for seven quarters, according to the median of 30 economists in a Bloomberg survey.
Spain’s 14 million households paid more than 858 million euros last year in capacity payments, said Cesar Martinez Villar, a regulatory affairs expert at Endesa in Madrid.
There is a risk new investments will be discouraged by capacity payments, according to Ben Caldecott, the program director at Oxford University’s Smith School of Enterprise and Environment.
“Capacity mechanisms are a band aid for a deeper, more structural market reform that’s required,” he said. “Poorly designed mechanisms paying out more than is needed will cost consumers more.”

Newfield signs Uinta Basin supply agreement
на 2:42 AM Tuesday, January 10, 2012Newfield Exploration Company signed a crude oil supply agreement with HollyFrontier Corporation to provide 20,000 barrels per day of supply capacity at HollyFrontier's Woods Cross, Utah, refinery.
"We are planning to significantly increase our drilling activities in the Uinta Basin – both in our proven shallow oil developments and in new and deeper oil horizons," said Lee K. Boothby, Newfield's Chairman, President and CEO.
"This new agreement with HollyFrontier helps ensure that our oil growth will be matched by capacity expansions in the Uinta Basin. We are growing an important source of domestic oil volumes and both Newfield and HollyFrontier will benefit throughout the next decade."
The new agreement spans a 10-year period with commitments commencing in 2014. This is the second of two recent agreements by Newfield to secure approximately 40,000 BOPD of capacity for the Company's planned oil growth in the Uinta Basin. The oil price differential associated with this agreement is not materially different than Newfield's current supply contracts in the basin.

Oil rises above $100 after surprise US supply drop
на 1:37 AM Monday, March 14, 2011Singapore - oil prices rose above $100 a barrel Wednesday in Asia a report showed that US crude oil and gasoline supply unexpectedly deleted suggest last week demand can be improved.
Benchmark crude oil April delivery was up 51 cents to $100.14 per barrel at midday Singapore time in electronic trading on the New York Mercantile Exchange. The contract rose $2.66 at $99,63 on Tuesday to rules.
Brent crude was delivery up 23 cents to 115.65 in London April $ per barrel on the ICE Futures Exchange.
The American Petroleum Institute said late Tuesday that crude oil inventories fell 1.1 million barrels last week, while analysts survey of Platts, the energy information arm of McGraw-Hill COS., an increase of 1.6 million barrels had predicted. Inventories of gasoline fell 4.9 million barrels and distillates fell 1.4 million barrels, the API said.
Administration reports its weekly supply data later Wednesday to the Department of energy energy information.
Traders are closely Libya, just, where cut nepotism oil production in the OPEC nation in two battles between supporters and opponents of Moammar. Investors are also concerned violent protests and political upheaval could break in the rest of the region as Iran, Iraq, the United Arab Emirates, Kuwait, Bahrain, Qatar, Oman and Saudi Arabia have more than 60% of proven oil reserves in the world.
"The fear of the underlying the is that the current will spread unrest due to Arab Middle East and Persia, East still," Cameron Hanover, said.
In other NYMEX trading in April contracts, heating oil 0.7 cents on $3.03 rose won a gallon and gasoline 1.9 cents to $3.00 per gallon. Natural gas of futures was by 2.5 percent to $3.85 per 1000 cubic feet.

Benchmark crude oil delivery to 27 cents to $84.59 was March a barrel at midday Singapore time in electronic trading on the New York Mercantile Exchange. The contract fell to pay 49 cents to $84,32 on Tuesday.
London Brent crude gained delivery 34 cents to $101.98 barrel April the ICE Futures Exchange.
The American Petroleum Institute said late Tuesday that crude oil inventories fell 354.000 barrel last week during of Platts, the energy information arm of McGraw-Hill COS., surveyed analysts an increase of 2.8 million barrels had forecast. Crude oil inventories at Cushing, Oklahoma key terminal increased by 250,000 barrels.
Inventories of gasoline rose from 1.2 million barrels and distillates fell 1.2 million barrels, API said.
The Energy Department's energy information Administration reported his per supply data later Wednesday.
"Current (API) surveys were exactly in line with the Energy Department at Cushing, what prices today for omen," the Schork report said energy consultant. "If confirmed, may (oil) the Department of energy be down for now behind us."
