Global wind power capacity will double by 2016 @oekonews.at

EWEA 2012 – Europe’s premier wind energy event took place in Copenhagen (16th to 19th of April). The European wind industry draws successfully balance to Europe’s sustainable energy future. I found an article about European’s wind energy perspective of the next 5 years – “The global wind power capacity will be more than doubled over the next five years”. The original article shows the outcome of EWEA 2012. This article is really worth it when it comes to the political side of sustainable energy. The platform I found the article is interesting as well: it’s an online daily newspaper for renewable energy and sustainability.

Gamesa Launches a New Turbine

mph — Wed, 25 Apr 2012 17:40:34 +0000

Gamesa, a global technology leader in the wind energy industry, on the occasion of one of the sector’s key events, EWEA 2012 Copenhagen (Denmark), announces the launch of a new wind turbine: the G114-2.0 MW Class IIIA, designed to achieve maximum returns from low-wind sites.

The G114 turbine, with unit capacity of 2.0 MW, features a a 114-metre diameter new rotor with a swept area of 10,207 m² that increases a 38-percent in swept area plus a 20-percent increase in annual energy output compared with the G97-2.0 MW turbine.

The new blade, spanning 55.5 metres with aerodynamic features developed using state-of-the-art technologies, also enables maximum energy production with reduced noise output levels. The machine offers a range of tower height options (from 93m to 140m or higher, depending on the target location), though we expect the 120m to be the most popular.

Low power density and proven technology

The new turbine promises to be a benchmark in the industry thanks to its low power density, the lowest on the market for its segment, and will help the company meet one of its targets for significantly reducing Cost of Energy (Coe) among Gamesa’s Class III products.

The Gamesa G114-2.0 MW completes one of the most versatile, proven and validated turbine systems on the market, the G9X-2.0 MW. By way of example, in the first year of the G97-2.0 MW turbine’s launch, Gamesa sold a total of 358 MW of the machine to customers on four continents. This turbine has evolved to become Gamesa’s new Class II product in the 2.0 MW market beginning in 2013.

The combination of a turbine with unit capacity of 2.0 MW and a selection of five different rotors (80metres, 87 metres, 90 metres, 97 metres and 114 metres in diameter) makes it ideal for any type of site, with availability levels exceeding 98%.

India, areas of China, Brazil and low-wind sites in Europe and the United States

“Our customers need to make the best use of the energy potential offered by low-wind sites, and thus require a turbine that can get maximum energy with a low investment cost. The G114-2.0 MW turbine is based on the same technology used in the G97-2.0 MW, but with some elements optimized and reinforced”, said Juan Diego Diaz, Gamesa’s Marketing Director.

The turbine’s characteristics make it ideal for growth markets, including India, China provinces closed to large consumption areas (Beijing and Shanghai), Brazil and low-wind sites in Europe and the United States.

Gamesa will begin manufacturing initial prototypes of the G114-2.0 MW in the third quarter of 2013, with the first turbines supply to begin at the end of the same year. From 2014, the company will start manufacturing market-ready series in all of the regions in which it has a manufacturing presence.

How big do you think turbines will be by 2020?

CROATIAN CENTER of RENEWABLE ENERGY SOURCES — Tue, 10 Apr 2012 07:58:00 +0000

Today’s turbines can be mind-bogglingly big, but big is not necessarily better. Mike Woebbeking, Vice President of GL group and chair of a session at EWEA 2012 in Copenhagen on 16 April that delves into turbine size, tells that size isn’t everything…

How has the average turbine size changed over the last decade?

Ten years ago the average size was around 1.5 MW, today it is close to 3 MW. Thus the average size of onshore wind turbines more or less doubled. For offshore wind this is more difficult to say. A decade ago there were only very few turbines installed offshore. The average size could be assumed to be around 1.5 MW. Today the average offshore turbine size is below 5 MW, however 7 MW turbines and bigger are under development. The average size of offshore turbines has roughly tripled within a decade.

How big do you think turbines will be by 2020?

In 2020 the average onshore turbine will be 4 MW. The average offshore turbine will be in the range of 12 MW.

What are the pros and cons of bigger turbines?

This is difficult to answer as there are many pros and cons for all existing types of turbines, sizes and concepts and the answer is very much depending on the site, its conditions and the strategy of the project as well as availability of components and turbines, not to mention pricing, capital and operational expenditure.

And how about smaller turbines?

If we are talking about smaller turbines, the benefits are easier ways of installation, availability of these products, building permissions (depending on the market) etc. However the capacity factors are limiting.

What are you hoping to get out of EWEA 2012?

Besides all the networking opportunities we will learn about the history in wind turbine development and challenges of the past, delegates will understand the actual challenges and needs in turbine design of the present as well as take home solutions to face these and last but not least all of us will look into the future and foresee the forthcoming turbine technology.
