Enel Open Data

Net generation in 2013 amounted to 63,244 million kWh, a decrease of 1,987 million kWh compared with 2012. The decline is mainly attributable to the decline in output for Enel OGK-5 (-2,610 million kWh), which was affected by a drop in demand for electricity in Russia, a selective reduction in the use of conventional generation plants and a number of planned stoppages at combined-cycle plants.

These effects were only partially offset by an increase in hydroelectric generation by Slovenské elektrárne thanks to the more favorable water conditions during the year.

Contribution to gross thermal generation

High-sulfur fuel oil (S>0.25%)  120  0.2%  257  0.4%  (137)  -53.3%

Total  62,026  100.0%  64,809  100.0%  (2,783)  -4.3% 
Enel Open Data

Gross thermal generation in 2013 decreased by 2,783 million kWh, to 62,026 million kWh, compared with 64,809 million kWh in 2012. The decline is essentially due to lower natural-gas and coal-fired output in Russia for the reasons noted above.

(1) Includes 406 MW in units classified as “held for sale” at December 31, 2013 and at December 31, 2012.

Net efficient generation capacity increased by 54 MW in 2013, virtually unchanged from the previous year.

Electricity distribution and transport networks

Electricity transported on Enel’s distribution network (millions of kWh)  13,996  14,606  (610)  -4.2% 
Enel Open Data

At December 31, 2013, the size of the electricity distribution network (located entirely in Romania) showed an increase of 512 km, essentially regarding new low-voltage connections installed during the year.

Electricity transported decreased by 4.2%, going from 14,606 million kWh to 13,996 million kWh in 2013.

Enel Open Data

Electricity sold by the International Division in 2013 amounted to 45,702 million kWh, a decrease of 6,321 million kWh (-12.2%) compared with 2012. The decline is attributable to:

  • a reduction of 807 million kWh in sales in the Russian market, largely in the free market;
  • a decrease of 5,009 million kWh in sales by Enel France, largely due to a reduction in volumes available as a result of exiting the Flamanville 3 project at the end of 2012, and to a decrease in the availability of supplies from EDF;
  • a decrease of 101 million kWh in sales in Slovakia and one of 404 million kWh in Romania, the latter due to improved weather conditions, which helped reduce electricity consumption.
