Siemens wants to lower offshore wind costs

Monday, 2 March, 2015 - 12:15

With new advancements in wind turbine technology, reduced grid access costs and innovative offshore logistics concepts for turbine maintenance, Siemens wants to lower offshore wind costs to below 10 €-ct/kWh by 2020.

From 2020 onward, Siemens wants to offer technologies that, in addition to optimized foundations, will allow offshore wind power to be produced on a LCOE level (levelized cost of energy) below 10 €-ct/kWh. Siemens is focusing on multiple aspects to achieve this target: At EWEA Offshore in Copenhagen, the company will present its latest advancements in offshore wind turbine technology. These include the evolution of a new offshore wind turbine which provides greater customer value while simultaneously reducing offshore project risks.

Siemens will also address how best to transport the generated power to shore. The high-voltage alternating-current (HVAC) offshore substations needed at present therefore should be substituted by the new Siemens Grid Access Solution in AC technology which acts as a distributed transmission asset. Focusing on the core electrical equipment and removing a number of optional ancillary systems means the module is light enough to be mounted together with a turbine on the same foundation or independently. This environmentally-friendly solution offers substantially reduced size, weight, and costs, while improving the customer's flexibility.

Siemens will also present cost-reducing concepts for operating offshore wind power facilities: As part of a new overall logistics concept, Service Operation Vessels (SOV) enable maintenance technicians to be available on site for weeks at a time, as well as safely access turbines in rough seas. With less time spent traveling to and from shore, maintenance operations become more efficient, significantly increasing the availability of offshore wind turbines.
