Lillgrund bei Malmoe, Schweden. 7. August 2008The Lillgrund wind farm is located in the Øresund between Malmö and Copenhagen. For this projectSiemens installed 48 2.3-93 wind turbines each rated at 2.3 megawatts (MW). The wind farm with a totalinstalled capacity of 110 MW is operated by the Swedish utility Vattenfall and officially went on line in June2008. It produces enough electricity to supply 60,000 Swedish households. The offshore substation platform(in the foreground) bundles the generated power and a 120-MVA power transformers transforms the 33kilovolts to a transmission voltage of 138 kilovolts so that the power generated by the wind farm can be fedinto the Swedish grid. Beside the transformer the platform also accommodated medium-voltage switchgearand an auxiliary power transformer for the substation.

Most eyes in the offshore wind industry are inevitably fixed on the 6-8MW class “super-turbines” that will lead the sector into the largest construction campaign in its history, starting with the German North Sea and UK Round 3 zone developments.

But beyond the visions of forests of SeaAngels, V164s and SWT-6.0s, a market for mid-sized offshore turbines is taking shape.

This aims to harness “comfort zone” projects – developments in up to 30 metres of water and less than 30km from shore that currently account for 93% of European and nearly 100% of Asia Pacific capacity, according to a recent report by IHS Energy.

By 2016, the expectation is that 5MW-plus machines will start to assert market dominance. But IHS says the run-up to that transition will be “make or break Log in to read complete article.
