Optimal Size Changes With Changing Demand and Technology

(p. B1) Twirling above a strip of land at the mouth of Rotterdam’s harbor is a wind turbine so large it is difficult to photograph. The turning diameter of its rotor is longer than two American football fields end to end. Later models will be taller than any building on the mainland of Western Europe.

Packed with sensors gathering data on wind speeds, electricity output and stresses on its components, the giant whirling machine in the Netherlands is a test model for a new series of giant offshore wind turbines planned by General Electric.

. . .

(p. B5) In coming years, customers are likely to demand even bigger machines, industry executives say. On the other hand, they predict that, just as commercial airliners peaked with the Airbus A380, turbines will reach a point where greater size no longer makes economic sense.

“We will also reach a plateau; we just don’t know where it is yet,” said Morten Pilgaard Rasmussen, chief technology officer of the offshore wind unit of Siemens Gamesa Renewable Energy, the leading maker of offshore turbines.
