The energy targets encompassed within this commitment respond to the need to move towards a more efficient and sustainable energy model regarding the use of energy, to reduce our dependence on foreign energy and contribute towards the fight against climate change. In this regard, the specific targets set include increasing to 20% the share of renewables in the electricity generation mix, reducing greenhouse emissions by 20% and achieving a 20% energy savings.
In October 2014, these targets were revised and a new European strategy regarding energy sustainability was established for 2030.
To achieve these targets it is imperative to further improve the efficiency of an electricity system which is very different to that which we had some years ago. In the past, the balance between supply and demand in the electricity system rested primarily on generation technologies that were highly manageable; capable of regulating their production to adapt it to the evolution of the demand. Today, this is changing. The electricity system is in a transition phase to a new model characterised by: a preponderance of renewable energies that demand that they be managed differently from conventional energies; the reduction of dependence on fossil fuels and the increase in demand-side agents which traditionally had had a passive role.
In this way, compensating for the reduced manageability of renewable generation, fostering energy efficiency measures, incorporating innovative technologies to improve the efficiency of the electricity system and managing the change in the consumers’ role, in a much more participatory manner, represent some of the challenges that need to be addressed in the coming years to achieve a more efficient and sustainable management of the electricity system as a whole.
