The Spanish wind turbine manufacturer reports net half profit of €22m ($29m) versus a loss of €33m a year earlier.  Revenue was €1.16bn, down 26% from €1.51bn in first half 2012, partly due to the slow US market after a record company performance there in 2012. A bright spot was operations and maintenance revenue which rose 18% to €180m

Profit margin before interest and tax surged in the January-June period to 5.9%
