The Energy Transformation sector extends over all the activities consisting in primary energy conversion into end-use energy, apt for its use in the end-consumption sectors. These activities include the oil refining sectors and the electric power and co-generation ones. Here are some of the most relevant facts in the last years:
There are two very remarkable facts in the oil refining sector during 2007-2010 that have affected energy efficiency in Spanish refineries: the new hydrocarbon specifications and the “dieselisation” of the Spanish car fleet. Nevertheless, Spanish refineries have managed to get adapted to these changes even if this fact has had a repercussion on the sector’s efficiency.
The Electric Power Generation sector has undergone a remarkable increase in energy efficiency, i.e. 5.7 percentage points during period 2007-2010. This fact has been possible thanks to an improvement in the performance of each kind of plant per energy sources, as well as to a larger participation of renewable energies in the generation mix, essentially of the hydroelectric, wind and solar kinds.
Last, the co-generation operational power in late 2010 in Spain amounted to 6,704 MW. This figure includes 658 MW from waste treatment and reduction in installations.
Here are some highlights within Action Plan 2011-2020 for the Energy Transformation Sector, taking year 2007 as a basis for the calculation:
Oil refining. As regards energy efficiency in refineries, no remarkable variations are expected within period 2010 – 2020, as the amendments in the hydrocarbon specifications have involved an increase in energy intensity in refining plants and an increase in CO2 emissions per unit product. It is to be expected that the most restrictive specifications will be balanced with the evolution of more mature cleaner hydrocarbon production technologies.
Electric Power Generation. An increase in the natural gas contribution for horizon 2011-2020 is to be expected, stabilised with the falling trend in nuclear electric power production. Coal will remain essentially stabilised, while the contribution of oil products to electric power production will show a falling trend. On the other hand, a stabilisation in the electric performance of around 52% is envisaged all along the period.
For all the above, an energy saving of 9,701 ktoe is expected for year 2020 in the co-generation sector, with respect to the situation of year 2007. This will prevent the emission of CO2 76,494 kt.
Co-generation. 3,751 MWe are envisaged to be installed by year 2020. On the other hand, the renewal of the power stock over 15 years’ old is established as a priority target, and it is estimated that its upgrading will achieve 3,925 MWe in 2020. As a whole, these actions are estimated to achieve annual primary energy savings of 1,699 ktoe in 2020, and will prevent the emissions of CO2 2,978 kt.
In this way, Action Plan 2011–2020 for the Energy Transformation sector raises an efficiency scenario with savings worth 11,312 accumulated ktoe per year for 2020, preventing the emission of CO2 79.230 kt.
Action Plan 2011-2020 establishes the following action measures for the co-generation sector:
feasibility studies for co-generation plants, energy audits for co-generations, development of co-generation plants in non-industrial activities, development of low-output co-generation plants, development of co-generation plants in industrial activities and a considerable modification of the existing installations.
IDAE’s action in this sector is featured by the financing of co-generation projects with the use of various associative formulas, supplementing in this way the actions set out in Action Plan 2011-2020.
