“Siemens aims for €0.08/kWh: Next generation turbines and foundations key to cutting costs offshore” (ReNews),(CleanTechnica) …and concrete is going to take a relevant part too (HWS).
Concrete is becoming a relevant part on the Offshore LCOE cost reduction. See:

“The SIEMENS new concrete precast/prestressed wind turbine tower for the USA: A ‘precast on-site’ concept which supports a 2.4MW turbine at 115.5 m rotor-axis height” (HWS)
Last week we were in New Orleans (LA) in the AWEA 2016 exhibition, where SIEMENS ENERGY INC. introduced a new tower, designed for a 2.4MW turbine and 107m (350 ft.) rotor, which means around 140T (127t) static load on top of the tower.
This CONCRETE tower reaches a height of 114m (374 ft.), which is a NEW RECORD in the US!
3 years ago in the US other OEM, ACCIONA WIND POWER, constructed a 100m high concrete precast/prestressed tower for a 3MW turbine.
It is a remarkable industrial product with various innovations, one of which is to introduce a new concept of concrete tower: It is “precasted on-site”, which means it is very near to the final position. This concept aims to remove the transportation of precast parts, which is expensive due to the heavy loads and large pieces.
Undoubtedly using higher towers is a current trend which aims to reduce the LCoE, and concrete helps make higher and more powerful turbines.

“The ‘Multi-MW’ wind turbines are increasing share market” (HWS)
The largest wind turbines are increasing share market, year by year (Source: Navigant Research).
“159m HEIGHT ROTOR AXIS. The new ENERCON hybrid tower to EP4 turbine-platform: A new record!” (HWS)
Last week we were in Hannover Messe (The prestigious German Industrial Fair), in which ENERCON presented the new platform EP4.
It is a remarkable industrial product with various innovations, which aim to reduce the LCoE without renouncing their best quality standards, which is well known as common in this brand.
Part of those characteristics is to use an improved hybrid tower, which must reach 155m HEIGHT, POSITIONING THE ROTOR AXIS AT 159m HEIGH: It is a NEW RECORD!
Undoubtedly using the highest towers possible in conjunction with larger blades and “Multi-MW” generators is a current trend.
