Buffett’s MidAmerican to Complete Iowa Wind Project by Year-End

MidAmerican Energy Co., a utility unit at Warren Buffett’s Berkshire Hathaway Inc. (BRK/A), expects to complete the 1,050-megawatt Wind VIII development in Iowa this year after finishing three of five wind farms in the fourth quarter.

The Wellsburg wind farm in Grundy County was connected to the grid in December, joining Lundgren in Webster County and Macksburg in Madison County, which were completed in November. Vienna II in Marshall County was finished in 2013. Only the 495-megawatt Highland in O’Brien County remains.

“By 2016, we’ll be able to produce enough energy from wind to meet the equivalent of approximately half of the electricity needs of our retail customers,” Adam Wright, vice president of wind generation and development for MidAmerican, said today in a statement.

The Des Moines, Iowa-based utility, a unit of Berkshire Hathaway Energy Co., provides electricity to 739,000 customers and natural gas to about 719,000.

MidAmerican will have invested more than $6 billion in wind-generation projects by 2016. Wind VIII, composed of 448 turbines, is expected to cost about $1.9 billion.

Wind power 'more resilient than fossil fuels'

Increasing wind power generation would make the UK's future energy supply more resilient to the fluctuating price of fossil fuels and cut costly importation, making energy prices more predictable.

So says a new report commissioned by trade body Renewable UK - The impact of wind energy on UK energy dependence and resilience - which looks ahead at how using more wind would serve the UK's energy needs in 2030 and 2030.

It reveals that 56% of the UK's gas supplies and 79% of coal was imported in 2013. Wind power reduced coal imports by an estimated 4.9 million tonnes and gas by 1.4 billion cubic metres, saving more than £579m in import costs.

Wind Investments to Top $101B by 2020

Global wind power investments are predicted to rise from $70 billion in 2013 to $101 billion by the end of 2020. The new report, “Global Wind Turbine Value Chain – Production, Market Share, Competitive Landscape and Market Size to 2020,” also finds that installed capacity should rise from around 364.9 GW in 2014 to 650.8 GW by 2020. © Ximinez | Dreamstime.com - Wind Turbine PhotoAlthough demand is on the rise, says Global Data who authored the report,” there may be a low growth rate for wind turbine components over the forecast period.

The Key To Making The Most Of Rising Wind Energy Production Is…

Supporting electricity grids as wind power reaches new highs

Wind turbines in HuhehotAs winter storms lash northern Europe, Denmark has announced record highs for wind’s contribution to its national electricity production. Global wind power capacity is set to grow by a further 50 to 100 percent by 2020, so it’s well worth considering how to make the most of these wind resources and the challenges that must be faced.

First, a little background: Last year, Denmark produced 39.1 percent of its electricity from wind, with its most productive month exceeding 60 percent. One some blustery days, the country sourced more than 90 percent of its electricity from wind.

Elsewhere in Europe, the United Kingdom and Germany also set record highs for wind energy.



No single solution

The answer is that there is no single solution to enabling high penetration of wind power. Instead, Denmark’s wind farm builders and operators and its transmission grid operator have together implemented a number of solutions to overcome intermittency and reinforce the grid to accept the power.

One of the main foundations of Denmark’s success is its ability to import and export electricity to its neighbors. The country has invested in interconnectors with a total capacity of almost 6.5 gigawatts.

If the wind is blowing in Denmark, it can export excess electricity. But if there’s a lull, it can import electricity generated by wind or other sources from other countries. The latest interconnector is Skagerrak 4, which ABB has just commissioned to improve existing connections between Denmark and Norway.

On the generation side, Denmark’s wind farms have also invested to ensure their output meets grid code requirements by mitigating the impact of transient voltages and power dips.

Denmark's strategy depends on having neighbors with easily adjustable output, like lots of hydroelectricity. But since they are separate nations, there may be political difficulties with such a strategy. Has it become a big political issue? Like "We don't want to be Denmark's batteries".

But if storage technologies improve enough, then that issue may be resolved by Denmark installing enough super batteries.

Oklahoma Legislature, like Congress, takes aim at taxpayer-funded wind energy credits

But the local wind-power industry, like those in many other states, is facing challenges from Republican lawmakers and others those who question whether the tax exemptions and credits and other subsidies for so-called “green energy” projects are worth the taxpayer investment.

I am actually not sure how much subsidy wind gets from states, versus the feds. Has Texas had an un-interrupted state wind subsidy over the last decade? Is there any political movement at all going forward, against the subsidy in Texas?

dashster - Actually most of the credit for the huge wind build out in Texas goes to our conservative Republican politicians who also represent some of the largest fossil fuel producers. Not just state granted tax benefits but we have an unregulated utility market to a far degree which allowed negotiations not typical elsewhere in the nation. For instance the folks in Austin voted to have their utility bills inflated a bit to provide a sub for wind builders. Now the folks in Austin get some of the cheapest electricity in the country.

I don't see the wind battles as R vs D or oil companies vs environmentalists. From what I read the problem often comes from local utility companies lobbying to save their somewhat monopolized markets.

New Wind Turbine Capacity Factor Could Increase From 40% To 60%

The article is titled, “The fast shift towards the « silent wind power revolution » in USA and the related huge energy and economic benefits.” You can read the 59-page PDF file, if you like.

On page 4, he says, “Using the new SWR wind turbines models in the 35 States with a potential of less than 60 GW with the 2008 models and a minimum gross capacity factor of 35 % would dramatically increase the aggregated areas suitable for wind power development (cf. slides 23-25): analysis from NREL shows that the aggregated areas suitable for a minimum gross capacity factor of 50% is increased from zero to 2 million km2 by shifting from the 2008 wind turbines to the 2013 SWR wind turbine (Su > 4 m2/kW), and that with the near future SWR technology (Su > 6 m2/kW), there are 2 million km2 available to deliver more than 60 % gross capacity factors. At a minimum 35 % gross capacity factor, the increase of potential aggregated GW in those 35 States is from 178 GW to respectively 2,913 GW and to 6,160 GW.”

On a previous page he mentions, “average annual US onshore capacity factor at 32.7 % in 2014”. So, would an increase in capacity factor from 32.7% to 60% would be a nearly doubling. He says that new technology, “future SWR wind turbines models with a reference Su value of more than 6 m2/kW and a hub height of up to 140 meters,” can generate these higher capacity factors.

You see issues where no are. Of course contries a seperate nations, however, the economic integration happens at a high rate: Austria is already a part of the German electricity market, we see crossborder business within the EU and with other non-EU countries like Switzerland.

As long as transmission line are much much cheaper than other alternatives we will see them, especiallially when large storage opportunities in Skandinavia or Alps are not used or underused.

U - Exactly. Which is one reason wind has done so well in Texas. Given that Texas is larger than a number of EU countries we had the same problem transferring power from one Texas "country" to another. But the state spent $7 billion of tax payer money to expand our transmission grid. So now we can "import" power from Texas "countries" with large wind capacity and very small demand to other Texas "countries" in need.

BTW in case you weren't aware: there are 3 major electrical grids in the US: the East, West and Texas grids. A long time ago Texas opted to stay out of the national grid system. We can still ship some electricity out of state. But while Texas produces more electricity than any other state we "export" only about 1% of our generation. And given the projected growth in electricity demand for the state as well as grid incompatibilities I doubt the state will ever be a supplier of a significant amount of electricity to the rest of the country.

And as I’ve pointed out before the success of wind in Texas has nothing to do with decreasing GHG production or saving the world from climate change. It was done for business reasons…good business reasons. Which is why IMHO Texas has been so much more successful than most states in promoting the alts: Folks in other states can say they care about GHG but when it comes to spending money to doing something substantial they lack the motivation to write the check. Gov Rick Perry might not be a supporter of climate change mitigation but he knows a good business deal when he sees it. That’s why he spent $7 billion in state money to expand our grid as well as providing other subsidies for wind power. And this from the gov of the largest fossil fuel producing state in the country.

Also: those new turbines may be the cat’s meow but as long as NIMBYism still prevails it won’t mean sh*t IMHO. LOL.

This discussion about replaceing/building new windpower electric grids to transfer electricity from one place to another reminds me of the Tennessee Valley Authority. That was a government, tax-payer funded project to bring electricity to places thhat had never been connected to the grid before.

And yet, there was resistance to that, too.

Interesting article about transitioning to wind power on a global scale. Of course it states the obvious of any transition to RE must utilize lots of fossil fuels. The article breaks down the amount of steel and concrete to transition to substantial amounts of wind power. Also it makes reference to nuclear also. All in all fossil fuels should have been used much earlier on to gradually transition to renewables. Well now we are in a pickle, we need to cut back of FF because of global warming and also we need FF for the normal activities of our economy.

The alternative is to calculate how much producing the oil products in a wind turbine from P2L would affect economy and energetical pay-back time.

The latter is affected by a few days, the former is in the <10% range. What is your issue?

Mass electrification is folly. The reality is that the large industrial users in Germany demand free electricity to remain internationally competitive. The small and medium enterprise (SME) in Germany demands free electricity to remain internationally competitive. The leftist guerillas in Germany demand free electricity to enact "justice". And so on and so on...

So what happens with these useless windmills? Same as the nuclear reactors. They get abandoned for a new fiat scam. Because NOBODY wants to pay for electricity! Only computational shell games are profitable!

The silicon valley wannabes in Germany are just following the The Peoples Republic of Kalifornia into the abyss!
