Time Series Analysis of Prices and Quantities at the Bulgarian Electricity Exchange in Conditions of Low Liquidity
Summary:
This article analyzes the time series of prices and quantities on the Bulgarian electricity exchange. The focus is on the period between January 2016 and June with the assumption that in this initial period for its operation, the stock exchange trade is not sufficiently liquid. Statistical tests and seasonal decomposition of quantities and prices are made. This allows the determination of their statistical properties. The analysis shows that both time series are characterized by mean reversion and have a weekly seasonality.

Cost of Electricity Produced from Waste Processing as a Prerequisite for Social Pricing
Summary:
In a period of energy crisis, deriving the cost of electricity is a significant problem. It appears as a significant contemporary challenge, and policies to control and limit it are the main priority of the European community on its way to a green economy. Depending on the tariff/price of electricity, which directly depends on its cost price, it is determined how much the population could afford to pay for their consumed electricity. Over 96 million Europeans are at risk of poverty and social exclusion. A population that would not be able to heat their homes in winter is about 57 million. Bulgaria is the country with the highest share of the poor and at risk of poverty, including energy-dependent households, which is also confirmed by the values of the Energy Poverty Index, according to which our country has the worst indicators among the member states of EU.
The current development draws attention to the specific features of waste-based electricity calculation. Method of pricing and formation of a sustainable model for formation of tariffs. The synergistic effect from waste processing to energy production is derived. Taxes paid and additional revenues from waste processing could positively affect the price of energy obtained from waste, i.e. to reduce cost and offset costs. This phenomenon can be used as a guideline for the development and improvement of social policy in the field of social tolerance and social support of the population in Bulgaria.

Nuclear Energy and the Transition to Low-Emission Electricity System
Summary:
This article explores national and European energy development plans in the context of the transition to a low-emission economy. The current structure of the electricity system of the country, the main objectives in the national strategic document for energy development "Integrated Plan in the field of energy and climate of the Republic of Bulgaria 2021-2030" and the package "Clean Energy for All Europeans" are presented. At the same time, the main challenges that Bulgaria will face in the decommissioning of carbon-intensive electricity generation (especially coal power plants) and the construction of replacement capacity have been identified. In this context, the article highlights the main advantages of nuclear energy as a safe, reliable, sustainable, and low-emission energy source and provides specific guidelines for the expansion of nuclear energy in the forthcoming transformation of the country's electricity system.
