alpha ventus draws positive balance

Last year, the German offshore wind farm alpha ventus fed 267.8 GWh of electricity into the transmission grid. This means that the energy yield exceeded the original forecast by 15.3%, says the operator consortium DOTI. The positive earnings trend is expected to continue in the first quarter of 2013.

The operators EWE, E.ON and Vattenfall say that 2012 was a very balanced year. In contrast to 2011, when the winter months were particularly profitable, income was distributed almost evenly throughout 2012. And in the first quarter of 2013, alpha ventus fed over 63 GWh into the transmission grid, which is nearly as much energy as during the same period in 2012.

"We are very satisfied with the operating year 2012," says Wilfried Hube, Managing Director of DOTI. "After just over two full years of operation, it is still too early to interpret this as a rule and permanently correct our future earnings forecasts upwards. Nevertheless, the reliably good yield of alpha ventus shows that we are on the right track with offshore wind energy. In the long term, our goal is to reduce maintenance costs for the facilities even further."

Mathematically, the twelve wind turbines of alpha ventus achieved 4,463 hours at full capacity in 2012, a value which is also at the level of operating year 2011. The equipment availability of the wind farm was at an average of 96.5% in 2012. Starting in May, various maintenance and service actions are planned on the wind farm, so DOTI is expecting slightly reduced availability for 2013. As the first German offshore wind farm, alpha ventus was officially put into operation in 2010 and since then has continuously fed carbon-neutral electricity into the German transmission grid.

Sometimes one and one add up to more than the mere addition of numbers. Structural Health Monitoring (SHM) of rotor blades is a complex and demanding task that requires very good hardware as well as professional data analysis in order to be able to make really precise and early statements about structural damage to the rotor blade. For this reason, two specialists have now joined forces to offer wind farm operators the best possible combination of forces on the market.

This installation will allow the farm in South Africa to lower the purchase of external energy, obtaining up to  80% of energy self-reliance as well as 70% energy self-consumption, that means 712 kWh of electricity produced daily vs. 895 kWh consumed (pict. Fimer)

More efficient: Pulcap pultruded profiles reinforce the blades of today’s wind turbines (pict. Röchling)

As part of the planned energy transition, increasingly wind power plants are being used to generate electricity. The international plastics processor Röchling Industrial launches a product made of composites, Pulcap, that enhances the stability of the rotor blades of wind turbines. Owing to their extremely high mechanical strength and low weight, the pultruded profiles enable an efficient and safe operation of wind turbines.

The experience of the TÜV SÜD experts has shown that even in the case of different WEC types, wind farms can often be assessed as a total complex (pict. TÜV SÜD)

Twenty years does not have to mean the end. Many wind-energy converters (WECs) can continue to feed power into the grid far beyond their original service life. TÜV SÜD experts know what is important in the Assessment and Verification of the Lifetime Extension of Onshore Wind Energy Converters (LTE) and how to leverage opportunities.
