| Pumped storage power plant |
a special type of a hydroelectric power plant that allows electricity to be stored. For this purpose, the upper water reservoir is used. Using excess electricity, water is pumped from the lower reservoir to the upper one. Pumped storage plants provide regulatory services to the national power system. During periods of increased demand for electricity, water from the upper reservoir is released onto the turbine. In this way, electricity is generated. |
| EMAS |
EcoManagement and Audit Scheme. It is an EU environmental certification scheme which functions on the basis of Regulation (EC) No 1221/2009 of the European Parliament and of the Council of November 25, 2009 on the voluntary participation by organisations in a Community eco-management and audit scheme (EMAS) |

| EU ETS |
European Union Emission Trading Scheme. It is a key element in the EU’s climate change policy and its main tool for reducing greenhouse gas emissions in a cost-effective way. It is the world’s first and so far largest emission allowance market. |
| European Green Deal |
An action plan for a sustainable economy in the European Union. It aims to achieve climate neutrality by 2050. Achieving this goal will require a socio-economic transition in Europe: one that is cost-effective, fair and socially sustainable. The new programme consists of initiatives in a number of closely related fields, such as climate, environment, energy, transport, industry, agriculture and sustainable financing. The EU will also provide financial support and technical assistance to individuals, businesses and regions most affected by the transition to a green economy. This will be done through the just transition mechanism that is expected to provide EUR 150 billion to the most affected regions in the years 2021-2027. |

| SAIDI |
System Average Interruption Duration Index – an index of the average (mean) system interruption duration (long, very long and catastrophic), expressed in minutes per customer per year, being the sum of the product of its duration and the number of customers exposed to the consequences of interruptions during the year divided by the total number of customers served. SAIDI does not include interruptions shorter than 3 minutes and is determined separately for planned and unplanned interruptions. It applies to outages on low voltage (LV), medium voltage (MV) and high voltage (HV) networks, while the SAIDI index in the quality tariff does not include outages on LV networks |

SAIFI does not include interruptions shorter than 3 minutes and is determined separately for planned and unplanned interruptions. It applies to outages on low voltage (LV), medium voltage (MV) and high voltage (HV) networks, while the SAIFI index in the quality tariff does not include outages on LV networks |
