Siemens Offshore Wind Makes Call for Suppliers



26 Apr 2010

Siemens Wind Power is looking for suppliers to support the expansion of its European offshore wind market interest and will host a sourcing event in Rotherham, UK on 17 June. The deadline for registering is Wednesday 28 April.

Siemens Wind Power announced its intention last month to invest more than £80m to develop an offshore wind turbine production facility in the UK. This is expected to generate 700 direct jobs and create many more through its supply chain. The move follows the announcement about the UK’s Round 3 development by The Crown Estate.

DECC’s UK Renewables Service is working with Siemens Wind Power, the UK’s largest provider of wind turbines and offshore grid connections, to organise the sourcing event to introduce them to UK companies.

They will be looking for suppliers who can feed into their global supply chain but there will be a special focus on the UK/offshore wind market.

This event will involve presentations from key procurement managers from Siemens Wind Power and then one to one meetings with potential suppliers.

Siemens’ areas of interest include:
