The Spanish energy mix

23 February 2017

What is or how is the SPANISH ENERGY MIX? What differences, in this respect, with the countries around us? What factors depends on its constitution? What substantial variations has it had in recent years? What is the percentage of renewable energies involved in electricity consumption?

What percentage of photovoltaic energy? Is it as expensive to fund as the rumor picks up?We present below the Mix Energético Español 2015, here called Electric Balance, which is broken down into peninsular and non-peninsular (we understand this differentiation as derived from different transport costs) and also collecting% change compared to the previous year.

In contribution percentages:

"By technologies, the production of peninsular electricity during 2015 was generated in 21.8% from nuclear power plants (22.0% in 2014), 20.3% from coal (16.5% in 2014), 19.0% with wind power (20.3% in 2014), 11.0% with hydraulics (15.5% in 2014) and the remaining 27.9% was distributed between combined cycles (10.1%), Cogeneration (10.1%), solar (5.1%) and others (waste and other renewable 2.6%). Below we present the Peninsular Electric Balance of October 2016, from the Monthly Bulletin (nº 118) of Oc-2016, of the Spanish Electric Network.

The comparative figures between 2014 and 2015 most outstanding regarding the generation mix and presented by this REE report are:

  •   The national demand (of electricity) grew 1.9% compared to 2014, after four years of decline.
  •   The national demand in 2015 was 263 TWh.
  •   Renewable energies contribute 36.9% of the total national production.
  •   Rising CO2 emissions due to lower hydro and wind generation.
  •   414 km more of circuit in the transport networks.
  •   The net balance of the energy exchange programs with other countries was again an exporter, although it decreased with respect to 2014
  •   118 km more submarine stretch.
