CECRE is the first center in the world where the generation of renewable energy producers—principally wind—is managed. It allows the largest possible amount of renewable energy to be integrated into the electric system, maintaining quality and security.

With CECRE Spain becomes the first country in the world with all of its wind farms connected to a control center. Cecre (Control Center of Renewable Energies) is a pioneering initiative put in place by Red Eléctrica Española.

Through 23 control centers that act as go-betweens, every 12 seconds Cecre receives real time information about each installation’s connection to the network, production and voltage at the connection point. Sophisticated tools use this data in order to check at all times if the total renewable energy generation can be integrated into the electric system without affecting the security of supply.

The Control Center of Renewable Energies has a decisive role in a system such as Spain’s that is so little interconnected. In order to avoid the problems that can arise with renewable energies, Cecre constantly analyzes the current scenario and anticipates the necessary operational measures to take in order to maintain the system’s security. The calculations are made using a breakdown of each wind farm and an aggregation for each of the transportation network. This is sent to the generation control centers which, in turn, send this information to producers so they may then modify the power assignment passed to the network.
