We were born amid the liberalization process of the electricity market with the target to become one of the main “independent” energy suppliers (not linked to the big distributing companies in the Spanish energy sector)

Before liberalization:

Consumers could only get their energy

from the Distributor and the Producer

could only sell to the Distributor.

After liberalization:

The Producer is not allowed to

distribute, and the Distributor is no

allowed to trade. The consumers can

choose their supplier and the Producer

can only sell to the market through

their representative agent.

These savings come from the aggregation of a large number of power plants of different production technologies to enter the wholesale market as one balancing positive and negative deviations:
