As climate change became one of the major concerns of modern society, various climate standards are implemented to lessen greenhouse gas emissions of global economy. The European Green Deal 2050 is one of the most important agreements that encourages businesses and countries to use renewable energy sources. This Bachelors’ thesis focuses on two European Green Deal’s measures – decarbonisation of the energy sector and investments in environmentally friendly technologies.
This thesis deals with energy sector decarbonisation, which is also a main goal of the company Melamin d.d. Kočevje. The company strives to become self-sufficient (energy self-sufficient) through the use of a solar power plant, capable of generating enough energy during daytime in summer months (June, July and August) to power the company as well as excess energy that will be stored in a battery storage and used during the night. Melamin would thus become a self-sufficient (energy self-sufficient) company during summer months. I outlined the planning process of the energy sector decarbonisation, the development of a self-sufficient company with a solar power plant and a battery storage. I presented the process of retrieving relevant data on company’s energy consumption using a software program Uniformance as well as a calculation of all relevant data on solar radiation using a software program PVGIS. I demonstrated the calculation of the solar power plant optimal rated power as per company goals by determining all the relevant parameters. I also calculated and determined all the necessary parameters of the battery storage. The effectiveness of this solution was assessed based on the comparison of the expected energy generation of the solar power plant and the company’s energy consumption during both summer months and the entire year. After comparing several non-binding offers to build a solar power plant and a battery storage, I selected the best one. I determined the amount of energy that the company would have to generate from the renewable energy sources in order to be self-sufficient all year long. To help assess the value of the whole investment, I presented some alternative options of electricity storage today and in ten years’ time. In the conclusion, I assessed the viability and feasibility of this investment by using the data obtained in this thesis. I concluded that at the present time, the viable solution is to only build a solar power plant, since the market price for battery storage remains too high for the investment to recoup in a sufficiently short time period.
