Siemens latest AC grid access solution offers 40% cut in costs

Siemens latest AC grid access solution

Siemens has launched a new alternating-current (AC) grid access solution for connecting near-shore wind power plants to the grid – promising 40 percent cut in costs.

Wind power produces can reduce construction, transport, installation, operation and maintenance costs by up to 40 percent with the new solution. The new solution is one third smaller in size and weight compared to a conventional AC platform.

Siemens said wind power produces can also reduce installation time by around 20 percent – also due to better availability of standard service operation vessels.

Siemens announced the launch of the AC grid access solution at the EWEA Offshore conference in Copenhagen.

Replacing the traditional AC transformer platforms, the new solution includes offshore transformer module (OTM) attached directly to a wind turbine. It is nominally rated in incremental 250 megawatt blocks.

Siemens said it can be linked together to provide the required transmission capacity even for very large wind parks. The new device can be installed on a wind turbine foundation separately. It can be installed at the transition piece between foundation and turbine shaft like a balcony. It is suitable for all wind power turbine models.

The latest AC grid access solution from Siemens is small and light enough to be mounted together with a turbine on the same foundation – eliminating the need for a special heavy lift vessel and saves additional costs.
