Harmonised and clear rules for the connection to the electricity system are necessary due to the dramatic increase in wind power penetration across Europe, says the wind industry.

Harmonised rules will lower wind energy production costs, contribute to an efficient management of the system, and lower the cost of the electricity for consumers. The European Wind Energy Association (EWEA) published a Generic Grid Code Format for wind generators. The initial challenge is not necessarily to fulfill certain technical requirements, but to ensure all stakeholders share the same understanding of the requirements.
