TURBINES OF THE YEAR 2020: ONSHORE TURBINES 4.5 MW-PLUS

Every year Windpower Monthly ranks the best wint turbine models. For your attention is 2020 rating of modern models of onshore wind turbine 4.5–plus.

MEDAL WINNERS

GOLD Enercon E-160 EP5

The installation of the 4.6MW E-160 EP5 E1 prototype in July was the most important milestone for Enercon in 2020. However, it is only a stepping stone in the German company’s mission to reshape itself and its product portfolio for current and future global demands.

When Enercon acquired Lagerwey in late 2017, the small Dutch supplier operated two “compact-drive” L136-4.5MW prototypes. This prototype became the core technology basis for Enercon’s EP5 platform, with the new E-147 and E-160 models announced less than a year later.

The E-160 E1 is a comprehensive product advancement, alongside with the 5.5MW E-160 E2 upgrade already planned for Q1 2021. Another major step for 2021, involving both the EP3 and EP5 platforms, is the E-nacelle. An extended nacelle rear section will accommodate the full electrical system. A large share of the planned projects that will feature Enercon turbines worldwide are to be fitted with the E-160.

SILVER Siemens Gamesa SG 5.8-155

The SG 5.8-155 comes with flexible onshore ratings — the highest is currently the 6.6MW. The first prototype of this new 5.X modular global platform will be supplemented in 2021 by the SG 5.8-170 with a record 170-metre rotor.

The 5.X platform is the outcome of a collaborative international development effort involving best-practice technology choices. The cumulative order intake for the 5.X platform exceeded 1.15GW within six months of its launch. 

BRONZE Vestas V162-6.0MW EnVentus

Back in 2012, Vestas realised the need for — and the benefits of — a new global modular turbine architecture. It introduced the ground-breaking medium-speed EnVentus technology principles in January 2019, together with two onshore sister models. The V162-6.0MW flagship prototype installed in October 2020 has one of the largest onshore rotors and is the second EnVentus prototype after the 5.6MW V150-5.6MW. Both were upgraded to 6.0MW at the same time.

With the EnVentus platform, Vestas has propelled medium-speed drivetrain technology into the onshore mainstream market. Only MingYang of China is a competitor at present with its hybrid drive technology. It is expected that more suppliers will switch to medium speed in the future.
