Speaking to Berliner Zeitung, the head of E.ON's Climate and Renewables division said it and other wind developers would put the brakes on future offhshore development if the grid operators failed to act.
Winkel said: "The situation is disastrous. The grid operators aren't keeping up. They have overestimated themselves an underestimated the problems. Secondly, they don't have sufficient financial incentives."
He also said that the suppliers are struggling to manufacture the required cables while there is a lack of regulatory coordination among the German authorities.
E.ON is currently building the 288MW Amrumbank project in the North Sea. Its other offshore pipeline projects include and has two other offshore projects in the pipeline, the 700MW Baltic Wind Farm off Sweden and the 219MW Humber Gateway in the North Sea.
His comments reflect recent issues warnings by European grid operator Tennet that it might struggle to install further offshore connections to North Sea wind farms due to a shortage of cables and cash.
The company said it has nine cable connections to German offshore wind farms currently under construction.
But it said that construction of further cables at this rate "is no longer desirable or possible" due to lack of skilled staff, shortages of materials and a lack of finance at Tennet and at supplier companies.
