The grid codes for wind turbines differ from one country to another. In Germany alone, there are five sets of regulations, which are constantly added to and revised. The situation is similar in Anglo-Saxon countries.
The wind energy division (GL Wind) of Germanischer Lloyd is now offering a comprehensive overview of the grid codes in the various countries applicable for manufacturers and operators. The "International Grid Code Comparison (IGCC)" records all the access rules of European and also non-European countries and presents an overview of the different requirements set by the system operators. The new service from GL Wind includes both a detailed list of the conditions that apply within the countries selected by the customer along with optional monthly updates.
