  1. RES integration into the current interconnected energy system Andrej Hanzel, managing director Centrum pre vedu a výskum,s.r.o. name: adress: state: contact:

  2. reNEWABLES PROS - CONS

  3. Renewable sources • Amount of present major fuels in Earth is limited (coal, gas, crude oil, nuclear). • Generation of electricity is not very environmentally friendly • SOx, NOx, solid particulars (???) is dangerous for environment • Ra wastes is still very huge problem • CO2 is also very huge problem name: adress: state: contact:

  4. Renewable is future of mankind • The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoule (EJ) per year. This is more energy in one hour, than the world uses during whole year. name: adress: state: contact:

  5. Sunshine-not equal across Europe (Earth)

  6. Wind turbine – limited opportunities for generation Average yearly utilization of installed capacity is 17% Slovakia wind 8 MW Source: Institut für Solare Energieversorgungstechnik

  7. Renewable • Achilles tendon • Very low energy density • Density of sunshine is 3,5-7 kWh/m2/day • It is several hundred thousand lower energy density thenin coal • Very complicated prognoses of occurrence • Consumption of electricity is often in time when generation is not possible (sun doesn’t shine, wind is not flowing, water is not falling etc.). Reserve capacity is needed on base of classical fuel. • Governmental support/incentives is veryquestionable.

  8. Cooperation on European level

  9. Europe is interconnected but…

  10. Technical problems of cooperation on European level • Each control area must be able: • To maintain export/import in range of ±20MWhr • Basic formula forenergyis:generation = consuption

  11. EUR/MWhr (EUR) Increasing of cost [MWhr] Marginal cost is going up Load factor present power plants is lower – cost is increasing

  12. Land Occupation

  13. Purchase prices/incentives for renewable These incentive increase retail and wholesale prices Is it generally agreed by public? Discussion didn’t held yet.

  14. What to do? • Superconductivity – in room temperature solves everything • Energy storage is to be without problem with high eficiency

  15. Thank you for your kind attention!
