Abstract
In this paper we discuss energy storage requirements for EUSALP region in Europe. EUSALP is an Alpine region that includes the entirety Switzerland, Austria, Slovenia, and Lichtenstein, as well as parts of France, Germany, and Italy. A model is presented that facilitates the estimation of the required technical amounts of energy storage and installed power of pumped storage hydropower plants. The aim of the model is to estimate the requirements of energy storage to assist in setting guidelines for stable and reliable future electric energy supply in the EUSALP region. The model is based on currently known patterns of energy consumption and generation and available information on the future increase of renewable electric generation capacity, energy consumption, and the introduction of electromobility within all EUSALP regions. The hourly balance of generation, demand, and storage within a selected future year is assumed. The results are presented such that a mix of scenarios is addressed. Among them are installed generation capacity, installed pumped hydro storage power, selection of photovoltaic and wind electric energy generation ratio, the charging of a selected percentage of electric cars, flexible run-of-river hydro electric energy generation, import/export, generation by nuclear and backup fossil fuel sources, and a selection of disturbances. Results show that energy storage capacities must be increased by a large margin regardless of the choice of demand site management strategies or flexible electric car charging. Around a requisite 10-fold increase in pumped storage hydropower capacity is estimated, while the estimated increase in required energy storage is even higher. Daily and seasonal variations are also discussed. Further, the amount of surplus electric energy generation is presented and discussed.

Title:Prihodnje potrebe po shranjevanju energije v alpskem prostoru
Abstract:
Članek prikazuje potrebe po shranjevanju električne energije za območje regije EUSALP v Evropi. EUSALP je alpska regija, ki vključuje celotno Švico, Avstrijo, Slovenijo, Lihtenštajn in dele Francije, Nemčije in Italije. Predstavljen je model, ki omogoča oceno tehnične potrebe po shranjevanju električne energije in inštalirane moči črpalnih hidroelektrarn. Cilj modela je ocena potrebnih kapacitet za shranjevanje električne energije za pridobitev smernic za stabilno in zanesljivo prihodnjo oskrbo z električno energijo na območju EUSALP. Model temelji na trenutno znanih vzorcih porabe in proizvodnje energije ter razpoložljivih informacijah o povečanju zmogljivosti proizvodnje električne energije iz obnovljivih virov, porabi energije in uvedbi elektromobilnosti v območju EUSALP v prihodnosti. Pri tem je bila uporabljena urna bilanca proizvodnje, povpraševanja in shranjevanja energije v izbranem letu prihodnosti. Prikazani so rezultati različnih scenarijev, pri čemer so upoštevane že inštalirane proizvodne zmogljivosti, zgrajene črpalne hidroelektrarne, izbrana razmerja med proizvodnjo električne energije iz fotovoltaike in vetrnih elektrarn, polnjenje izbranega odstotka električnih vozil, prilagodljiva proizvodnja električne energije hidroelektrarn, uvoz in izvoz električne energije, proizvodnja električne energije nuklearnih elektrarn in rezerve virov fosilnih goriv ter izbor motenj. Rezultati kažejo potrebo po velikem povečanju kapacitet za shranjevanje električne energije, ne glede na izbiro strategij upravljanja povpraševanja ali prilagodljivega polnjenja električnih vozil. Ocenjuje se, da je potrebno približno 10-kratno povečanje zmogljivosti proizvodnje črpalnih hidroelektrarn, medtem ko je potreba po povečanju shranjene energije še večja. Pri tem obravnavamo tako dnevne in sezonske spremembe kot tudi količine presežene proizvodnje električne energije.
