German engineering firm Siemens has signed a long-term agreement to offer its services and maintenance for the RWE's Rhyl Flats Wind Farm, which is located off the coast of North Wales in the UK.

The agreement for 15 years is an expansion of a previous service and maintenance deal with Siemens which started when the facility was commissioned in 2009.

The offshore project is equipped with 25 SWT-3.6-107 turbines and has a maximum installed capacity of 90MW. Rhyl Flats Wind Farm has the capacity to generate enough power annually to meet the energy demands of around 61,000 average households in the region
