In the first nine months of 2015, national electricity demand in Spain (peninsular and non-peninsular) was 198,710 gigawatts-hour (GWh), a figure that represents an increase of 2.5% with regard to the same period last year.

In regard to peninsular demand, the cumulative value in the first three quarters of the year reached 187,359 GWh, representing an increase of 2.5%. After factoring in the influence of the seasonal and working patterns, the growth has been 1.1% than in the same period last year.

The maximum values for instantaneous power and hourly demand on the Spanish peninsula were both set on 4 February and were the following: instantaneous power with a peak value of 40,726 megawatts (MW) at 7:56 pm and hourly demand with a peak value of 40,324 megawatt-hour (MWh) between 8:00 pm and 9:00 pm. The maximum value for the daily demand was recorded on 20 January with 821 GWh. Both the maximum summer and winter values recorded in the first nine months of 2015 are greater that those registered in 2013 and 2014.

From January to September 2015, renewables have covered 38.6% of net generation on the peninsula, 5.7 percentage points lower than the same period last year. This decline in the contribution of renewables to the generation mix is mainly explained by the drop in hydro generation, which has fallen by 4.8 percentage points in the coverage.

Wind energy generation has also reduced its weight in the generation mix structure, 0.8 percentage points less than in the same period in 2014. However, it is the third technology with the greatest weight in the net generation with a contribution of 19.1%, surpassed by nuclear and coal-fired generation which have represented 21.9% and 19.5%, respectively, of the generation mix structure in the first nine months of 2015.

58.6% of net electricity generation on the peninsula during this period was obtained using technologies which produce zero CO2 emissions.

In the first nine months of 2015, electricity demand in the whole of the non-peninsular systems increased by 2.6%, a growth very similar to that recorded on the Spanish peninsula.

Demand in the Balearic Islands has registered an increase of 4.8%. After factoring in the influence of the seasonal and working patterns, the growth has been 2.3% higher than the cumulative figure registered until September 2014. The weight of renewable energy has been 2.9% of net generation, a value slightly lower than that registered in the same period last year.

Demand in the Canary Islands has registered an increase of 1.2% with regard to the same period in 2014, a figure that, once corrected, represents an increase of 0.9%. Renewable generation represented 9.1% of the generation mix structure.

Lastly, Ceuta has registered a decline of 1.4% and Melilla an increase of 3.6%.

New all-time wind power generation records

During the month of January 2015new all-time wind power records were reached. On 29 January a new all-time high for instantaneous wind power energy was set, registering 17,553 MW at 7:27 pm, a value 2.9% higher than the previous all-time high set on 6 February 2013, when 17,056 MW was registered.

Additionally, the all-time high for hourly wind power production was also set between 7.00 pm and 8.00 pm on 29 January when it reached 17,436 MWh, a value 3.1% higher than the previous high of 16,918 MWh, also set on 6 February 2013. Lastly, the all-time high for daily wind power production, previously recorded on 25 March 2014, was exceeded this year on 30 January.
