Spanish wind turbine manufacturer Gamesa, the world’s fourth ranked company in the sector, has announced it will lay off workers at its two wind turbine manufacturing plants in Pennsylvania USA, owing to lower demand for blades. The fall of in demand is in line with a general drop in order book entries for major suppliers in H1 of 2012, as reported by analysts Bloomberg.

73 employees will be laid off at Edensburg, where Gamesa makes turbine blades, representing about 30 percent of the workforce. There will be another 92 at Fairless Hills in Bucks County.

The company said it hopes to bring those workers back in about 10 weeks if the American Renewable Energy Production Tax Credit, currently being debated in the Senate, is extended.

If the tax credit is not extended, the company said it will concentrate on blades for wind farms in markets outside the USA.
