From January to June, renewable energies covered 50.7% of the generation on the Spanish peninsula and 73.4% was obtained using technologies that produce zero CO2 emissions.

National demand (peninsular and non-peninsular systems) for electrical energy during the first six months of 2016 amounted to 130,724 gigawatt hours (GWh), which means that there is no variation compared to the same period last year. After having factored in the effects of seasonal and working patterns, demand increased by 0.1%.
As for peninsular demand during the first half of the year, this totalled 123,613 GWh. After having factored in the effects of seasonal and working patterns, demand growth was 0.1%.
Maximum values for instantaneous power and hourly demand on the Spanish Peninsula occurred on 17 February, with 38,464 megawatts (MW) at 8:37 pm and 38,239 megawatt hours (MWh) between 8:00 pm and 9:00 pm, respectively. The maximum daily demand was registered on 18 February with 783 GWh.
From January to June this year renewable energies have covered 50.7% of the peninsular generation, a value that is 8.3 percentage points higher than in the same period last year. The weight of renewable generation for all months in the period was higher than those recorded throughout the previous year.
The increase in the share of renewable energy is explained by the change in the generation mix on the Spanish Peninsula that took place in the first six months of the year. Specifically, the most significant change was the increase in hydroelectric generation which rose 6.6 percentage points in the peninsular generation from January to June. In addition, it was the technology with greater share in the generation mix in the months of April and May, with 25.9% and 26.4%, respectively.
Wind-power generation also increased its share in the generation mix by two percentage points over that registered in the same period in 2015. It was the technology which contributed most in the generation mix in the first three months of 2016.
In contrast, there was a decline in those technologies that use fossil fuels. Coal-fired generation fell by 8.8 points and combined cycle reduced its share by 1 point in the peninsular generation mix.
73.4% of the peninsular generation in this period came from technologies that produce zero CO2 emissions.
New all-time renewable power generation records
During the first half of 2016 new all-time wind power records were reached. On 11 January, an hourly energy of 17,390 megawatt hours was recorded between 1:00 pm and 2:00 pm, representing an increase of 1% over the previous high set on 29 January 2015.
Additionally, the all-time high for daily wind power production was also set on 12 February when it reached 365,348 megawatt hours, exceeding the previous high set on 30 January 2015. Also on 12 February the all-time high for daily renewable generation on the peninsula was set at 518 GWh.
Installed power capacity on the Spanish Peninsula
As at 30 June 2016, the peninsular electricity system had an installed power capacity of 100,101 megawatts (MW), 0.9% lower than December 2015. The decrease of 932 MW is due to the closure of five coal-fired power stations: Elcogás, Compostilla 2, Narcea 1, Puertollano and Soto 2.
In the first half of 2016, demand for electricity of the non-peninsular systems as a whole increased by 0.6%, a higher growth to that registered on the Spanish Peninsula.
In the Balearic Islands demand fell by 0.5%. After having factored in the effects of seasonal and working patterns, demand increased by 2.5% over the same period in 2015. 3.2% of generation came from renewable energies, very similar to the value registered in the same period last year.
In the Canary Islands, growth in demand was 1.4% up on the same period last year. After having factored in the effects of seasonal and working patterns, the increase was 0.8%. Renewable energy production represented 8.2% of the generation mix, which is slightly lower than the first six months of 2015.
Lastly, Ceuta registered an increase of 0.8% and Melilla experienced a drop of 2.1%.
