Texas city one of first to be powered solely by wind and solar energy - NPR

According to this report on NPR, who would have thought that Georgetown in conservative red state Texas would be one of the first cities in America to be powered entirely by renewable energy? It’s true.

But it’s all about the Benjamins, Georgetown Mayor Mr Dale Ross told NPR. It’s our love of green — green rectangles and green energy, the rectangles signifying dollars. First and foremost it was a business decision.

There was never any talk of global warming or climate change during the city’s deliberations in 2012 about its power source going forward.

He said that “I don’t think they’re ever going to accuse Georgetown of being the next Berkeley.”

The city realized that there was enough wind and solar power available, that it was fairly predictable and that the prices wouldn’t fluctuate as much as oil and gas prices.

Texas has led the nation in wind energy for the past decade while under then-Gov. Rick Perry, now the nation’s energy secretary.

But Perry didn’t promote the industry because he was any kind of tree-hugger. As Texas Tribune reporter and former Star-Telegram Austin bureau chief Jay Root told NPR: “I don't think anyone would call Rick Perry an environmentalist, including Rick Perry. ... But the guy knows how to sniff out a dollar. Here's a guy from West Texas who saw that you can make money off of the wind blowing. Like, that's a no brainer."

Tom Kiernan, chief executive of the American Wind Energy Association, told the Star-Telegram last month that the outlook for wind energy under the Trump administration looks promising, largely because it doesn’t cost much, adds jobs and is already being used by major companies such as GM in Arlington, Facebook, which is building a data center in north Fort Worth, Apple, Google, Amazon, Netflix and others.

Strong winds knock down wind turbine in Rhode Island

The Associated Press reported that strong winds have toppled a wind turbine at a Rhode Island beach.

Rhode Island Gov. Gina Raimondo said that the wind knocked over the turbine at Salty Brine Beach in Narragansett on Tuesday. It's owned by the state Department of Environmental Management.

A photo of the turbine posted by the town's emergency management agency showed the turbine's metal base twisted and bent over the snow-covered beach.

Raimondo said that no one was hurt and the state will fix it once the storm is over. Winds in the area are gusting up to 55 mph. Approximately 215,000 customers were without power Tuesday from Virginia to New England.

Avangrid Renewables to develop offshore wind near North Carolina

Spanish energy developer Avangrid Renewables won an auction for the development rights for offshore wind off the coast of North Carolina.

Avangrid already operates 60 onshore wind developments in the United States, including the Amazon Wind Farm U.S. East in North Carolina, the News & Observer reported.

The site lies 27.6 miles from the shore, and extends 25 miles into the Atlantic Ocean.Avangrid’s next steps will be to measure wind speeds and assess the site.

Ms Katharine Kollins, president of the Southeastern Wind Coalition, said the $9 million bid was surprisingly high.

She said that “It’s extremely encouraging how the offshore wind industry feels about continued development and growth, specifically in North Carolina.”

Other bidders included Wind Future, Statoil Wind and wpd offshore Alpha.

Two other sites for offshore wind near Kitty Hawk will be offered for lease in the near future.

US first offshore wind farm powering more of Rhode Island

AP reported tht the nation's first offshore wind farm is powering more of Rhode Island. The Block Island Power Company says it shut down its diesel generators and transferred the island's electrical grid Monday, a savings of nearly 1 million gallons of diesel fuel annually.

Deepwater Wind's five turbines began generating power for the mainland grid in December. Block Island had to be connected with a new cable.

The power company said that the early morning transfer was the final step in a process that began more than a decade ago, when the cost of fuel for the generators drove electrical costs to more than 60 cents per kilowatt hour.

US wind industry installs 2,000MW capacity in Q1

The US wind industry installed 2,000 megawatts of capacity in the first quarter, nearly four times the amount installed in the same period last year, as developers race to capture a lucrative federal tax credit that is gradually being phased out. The American Wind Energy Association said that it was the industry's biggest first quarter since 2009.

Project construction and development activity is also robust, as the federal production tax credit for wind projects does not expire until 2020. Starting this year, however, the credit's value will drop by 20 percent each year for projects that start construction from 2017 through 2019.

AWEA said that there are 9,025 megawatt (MW) of wind projects under construction and an additional 11,952 MW in advanced development.

About a quarter of the megawatts installed in the first quarter are contracted to buyers outside the utility industry, including the U.S. Army, Amazon.com Inc and Alphabet Inc's Google. Home Depot Inc and Intuit Inc also signed contracts for new wind projects for the first time in the first quarter.

Vestas Wind gets order from Argentine Aluar Aluminio Argentino

Renewables Now reported that Vestas Wind Systems A/S received an order for 50 MW of wind turbines from Argentine aluminum producer Aluar Aluminio Argentino SAIC.

The Danish wind turbine manufacturer will supply turbines for the 50-MW El Llano wind park in the province of Chubut that will provide electricity for Aluar's aluminium smelting. Vestas said the project highlights the attractive economics of wind energy for energy intensive industries. The wind farm will also help Aluar meet a requirement under the Argentinian Renewable Energy Law 27.191 that large electricity users source a portion of their demand from renewables.

The contract is for the supply and installation of 14 V126-3.45 turbines in 3.6 MW power optimised mode. It also includes a 15-year Active Output Management 5000 (AOM5000) service agreement. Delivery of the turbines is scheduled for the fourth quarter of 2017, with commissioning expected in the third quarter of next year.

Massachusetts' bid to become the nation's leader in offshore wind power

AP reported that Massachusetts' bid to become the nation's leader in offshore wind power is ramping up. The state's electric utilities National Grid, Eversource and Unitil are slated to release by June 30 their requirements for projects seeking to develop the state's first ocean-based wind farm. That sets in motion an ambitious effort to put Massachusetts ahead of states like New York, New Jersey and Maryland also seeking to establish their presence in the nascent US industry.

Here's a primer on where things stand:
NEW ENERGY LAW
A state law passed last year to boost Massachusetts' use of renewable energy outlines the process for developing offshore wind power.

The law calls for generating at least 1,600 megawatts of power, roughly enough electricity to power 750,000 homes annually, from offshore wind by 2027.

To accomplish this, the utilities are required to secure long-term contracts with wind farm developers in at least two phases: a bid request this June and another in 2019.

The law also calls for generating up to 1,200 additional megawatts from other clean energy sources, including hydropower, onshore wind power and solar power by 2027.

KEY PLAYERS
At least three companies have expressed interest in the bid: Rhode Island's Deepwater Wind, Denmark's DONG Energy and Vineyard Wind of New Bedford, Massachusetts.

Those three have already taken the key step of securing federal leases to develop offshore wind farms miles of the coasts of Martha's Vineyard and Nantucket, where the state is focusing its offshore wind efforts.

Each firm comes with its industry bonafides.

Deepwater Wind opened the nation's first offshore wind farm off Block Island last year -- a five-turbine project generating 30 MW.

DONG Energy has installed hundreds of turbines in waters off Europe and has partnered with Eversource on its Massachusetts venture.

And Vineyard Wind is partly owned by Portland, Oregon renewable energy developer Avangrid Renewables and Copenhagen Infrastructure Partners of Denmark.

ROUGH DRAFT
The utilities -- in concert with state agencies -- have been developing their bid requirements for months.

The most recent draft calls for proposals generating between 400 to 800 megawatts of power and outlined key dates, including a December deadline for submitting applications and a May 2018 deadline for picking a winner or winners.

But the utilities have also sought input from offshore wind companies and other stakeholders, so it remains to be seen if those specifics are further tweaked.

SIZE MATTERS?
As the utilities have drafted their bid requirements, there's been some debate about the right size for the wind farms.

DONG Energy argues that larger projects generating up to 800 megawatts provide "efficiencies of scale" that would lead to lower electricity costs for ratepayers.

Vineyard Wind believes the more practical approach is developing four projects of 400 megawatts each. And Deepwater Wind has argued for a range of projects of varying sizes.

"We think a more gradual approach makes the most sense," said Jeffrey Grybowski, Deepwater Wind's CEO. "You need to walk before you run."

TOO SLOW?
Timing also has been a concern among some stakeholders.

The Conservation Law Foundation, a nonprofit environmental advocacy group, has advocated for an accelerated timeline that would allow construction to start as soon as next summer and the wind farm to be operational by 2023.

Vineyard Wind CEO Erich Stephens warns that a prolonged selection process makes it harder for firms to maximize their benefit from federal investment tax credits that are gradually being phased out. That, he said, could ultimately impact costs passed to ratepayers.

Mr Stephens said that "Even just a few months makes a huge difference."

THE TRUMP EFFECT
Offshore wind developers seem united on at least one point: they're not overly concerned about President Donald Trump's policies on renewable energy just yet. Trump was a vocal critic of offshore wind technology as a candidate and businessman.

The companies note that states play a vital role in setting the nation's energy priorities since they regulate utilities, and Massachusetts' Republican Governor Charlie Baker has reaffirmed the state's commitment to its clean energy goals despite the country's withdrawal from the Paris climate change agreement.

Offshore wind turbines need adjustments to survive Category 5 hurricanes in Boulder

Tree Hugger reported that offshore wind turbines are growing in size, strength and power output, but new research from National Center for Atmospheric Research in Boulder, Colorado and the US Department of Energy's National Renewable Energy Laboratory in Golden, Colorado tells us that while these improvements are amazing, there are still more to be made. As wind farms start to be approved and finally constructed along the Atlantic coast of the U.S., one of nature's most powerful occurrences must be considered: hurricanes. Current turbines are strong enough to withstand them, but the study found that the strongest hurricanes, Category 5, would likely be more than the turbines could take.

In those hurricanes, wind speeds reach up to 90 meters per second.

Mr George Bryan of NCAR, said that "Wind speeds of this magnitude have been observed in hurricanes before, but in only a few cases, and these observations are often questioned because of the hazardous conditions and limitations of instruments. By using large-eddy simulations, we are able to show how such winds can develop and where they occur within hurricanes."

The other thing to consider is the veer of the wind in these hurricanes, or the change in wind direction across a vertical span. In a Category 5 hurricane, the wind can change direction by as much as 55 degrees between the rotor and hub of a wind turbine, meaning an overwhelming strain on the blades.

The Atlantic coast is threatened by hurricanes each year, and while the strongest of hurricanes are not common, they happen with enough frequency that wind farms will need to be built with those threats in mind.

Professor Julie Lundquist of ATOC and CU Boulder's Renewable and Sustainable Energy Institute , said that "Success could mean either building turbines that can survive these extreme conditions, or by understanding the overall risk so that risks can be mitigated, perhaps with financial instruments like insurance. The next stage of this work would be to assess how often these extreme winds would impact an offshore wind farm on the Atlantic coast over the 20-to-30-year lifetime of a typical wind farm."

The US finally has its first wind farm at Block Island, Rhode Island and the potential for wind energy generation along the east coast is great. It will be a necessary part of the country's transition to cleaner energy, so studies like this will hopefully guide engineers and planners to build turbines and wind farms can take whatever nature throws at them, or at least plan for the costs when they can't.

Wind generation capacity outpacing coal in Texas

Power Mag reported that an analysis by the University of Texas at Austin’s Energy Institute shows wind power generation capacity in Texas may already have surpassed coal-fired capacity in the state, and wind almost certainly will have leapfrogged coal by early next year, as wind farms continue to dot the landscape while more coal plants in the state are shuttered. The report from the Energy Institute comes on the heels of last week’s announcements of the closing of three large Vistra Energy coal plants in Texas—Big Brown, Sandow, and Monticello, operated by Vistra subsidiary Luminant. All three plants are set to close in early 2018.

Vistra said that the plants no longer are economic to operate, noting they are “economically challenged in the competitive ERCOT [Electric Reliability Council of Texas] market.” The three plants represent a whopping 4.2 GW of coal-fired generation capacity. Vistra Energy President and CEO Curt Morgan in a statement said “the market’s unprecedented low power price environment has profoundly impacted [Vistra’s] operating revenues and no longer supports continued investment [in the coal plants].”

The Energy Institute in an October 13 release said “New coal retirements announced by Luminant means ERCOT will soon lose significant coal generation capacity. At the same time, wind capacity is expected to increase by nearly 4,000 [MW] by 2018, meaning wind capacity will soon exceed coal capacity in Texas. Given current capacity factors for the respective technologies, it’s conceivable that energy generation from wind could possibly overtake coal in the near future.”
