If BigWind gets Higher, we can get closer, right? NO!!

That’t right, BigWind is proposing TALLER turbines in the USA…while they lobby, hard in Ohio, for SHORTER safety setbacks! ZERO logic. Additionally, as farmers complain that soil compaction occurs, what will occur as a result of LARGER and HEAVIER equipment on our roads and fields??????……

US developers propose record 207-metre wind turbine height

A new Department of Energy report shows that the wind industry is increasingly comfortable with taller turbines that optimise project cost and performance

By Richard Kessler in Fort Worth,15 August 2019

 

Wind project developers in the US through May have proposed turbine heights up to a record 207 metres (680 feet) versus an average 146 meters for 2018 installations, as the industry benefits from technology advances, according to a new Department of Energy (DOE) report.

 

Permit applications filed with the Federal Aviation Administration (FAA) this year show 44% of proposed turbines will exceed 152.4 meters in height (from ground to blade tip extended directly overhead), up from 39% in 2018 and 14% in 2017. The FAA regulates all aspects of civilian aviation…

Lawrence Berkeley National Laboratory scientists Mark Bolinger and Ryan Wiser, primary authors of the 2018 Wind Technologies Market Report, noted the FAA data represents total turbine height, not hub height, and therefore includes the combined effect of both tower and rotor size…

In 2018, turbine size continued to increase in response to technology advances as developers grow more comfortable with larger, taller machines that optimize project cost and performance…

 

Both rotor diameters and hub heights increased in 2018, continuing the long-term trend, according to the report…

Vestas CFO sees scope for upscaled turbines on land and sea

The OEM could boost the nameplate capacity of both its onshore and offshore models further, CFO Fredriksson says

By Bernd Radowitz in Berlin,15 August 2019

 

Vestas could upscale both its currently most powerful onshore and offshore turbine models further to reach a greater nameplate capacity, the Danish OEM’s chief financial officer Marika Fredriksson told Recharge.

The manufacturer will only develop any new product or concept if it sees a clear path to both lower levelised costs of energy (LCOE) and “something in the pocket for us,” the CFO had stressed in a conference call with investors on second quarter earnings..

 

Asked be Recharge in an interview little later, whether she sees greater chances for improvements in onshore or offshore – given the fact that Vestas has already presented a 5.6MW onshore model and a 10MW offshore machine – Fredriksson said: “I would say both.”

 

“In onshore, we see a good potential to further decrease the LCOE. We have a modular approach with EnVentus and still see a great potential to lower costs further,” she said…

 

Vestas in January had unveiled its EnVentus modular platform, launching two 5.6MW models as its so far highest-capacity machines on land.

 

While most rival OEMs meanwhile also have presented turbines in the 5MW class, going much higher in onshore capacity could lead to growing headaches as far as road transport is concerned…

 

MHI Vestas chief executive Philippe Kavafyan at the launch of the V164’s 10MW version had already said the OEM likely won’t stop at that size and will move forward with more “incremental innovation through all parts of the value chain.”
