Analiza donosnosti investicije v sončno elektrarno ob spremembi sistema neto meritev

PEČUH, BLAŽ (author), Blažič, Boštjan (mentor)

Magistrsko delo predstavlja temeljito analizo vpliva zakonodajnih sprememb v obračunu električne energije iz obnovljivih virov. Posebno pozornost namenja donosnosti investicij v male sončne elektrarne ter pametne hiše ob uvajanju električnega hranilnika in električnega vozila v sistem. Spremembe v zakonodaji nakazujejo morebitno zmanjšanje donosnosti naložb v sončne elektrarne, a hkrati se nakazuje potencial za idealen scenarij avtonomnosti z integracijo električnega hranilnika in vozila. Trenutne raziskave kažejo, da uporabniki malih sončnih elektrarn dosežejo približno 25% samozadostnost, ki se z uporabo hranilnika lahko še poveča. Cilj raziskave je analiza različnih scenarijev novega načina obračuna električne energije, ob upoštevanju velikosti sončne elektrarne, cene električne energije in izbire hranilnika. Analiza sledi hrvaškemu modelu obračuna (angl. net metering), ki temelji na prehodu iz letnega na mesečni obračun, kar omogoča vpogled v potencialno prihodnjo situacijo v Sloveniji. Raziskava zajema različne scenarije in lokacije znotraj Slovenije, s poudarkom na raziskovanju možnosti za učinkovito povračilo stroškov investicij lastnikov sončnih elektrarn. S celovito analizo trenutnega stanja samooskrbe in distribucijskega omrežja magistrska naloga prispeva k razumevanju trajnostne prihodnosti energetskega sektorja v Sloveniji.

• Title: Analysis of the return on investment of a solar power plant under a change of the net metering system

Abstract

The master's thesis presents a thorough analysis of the impact of legislative changes on the billing of electrical energy from renewable sources. Special attention is given to the profitability of investments in small solar power plants and smart homes, considering the introduction of an electric storage system and an electric vehicle into the system. Changes in legislation indicate a possible decrease in the profitability of investments in solar power plants, but at the same time, they show the potential for an ideal scenario of autonomy with the integration of an electric storage system and vehicle. Current research shows that users of small solar power plants achieve about 25% self-sufficiency, which can be increased with the use of a storage system. The aim of the research is to analyse various scenarios of the new method of electricity billing, considering the size of the solar power plant, the price of electricity, and the settings of the storage system. The analysis follows the Croatian billing model (i.e., net metering), based on the transition from annual to monthly billing, providing insight into the potential future situation in Slovenia. The research covers various scenarios and locations within Slovenia, emphasising on exploring the possibilities for effectively covering the investment costs by the owners of solar power plants. With a comprehensive analysis of the current state of self-sufficiency and the distribution network, the master's thesis contributes to understanding the sustainable future of the energy sector in Slovenia.
