Gross load = The hourly value of electrical power supplied to the transmission system by connected electricity generators + net balance (it is shown with and without the value of pumping power at pumped storage hydroelectric power stations). Electricity consumption in the CR = NNC - HL h. House load for electricity (HL e ) = This expression denotes the consumption of electricity that is required for the electricity generating process. It covers all operations that are crucial for electricity, including losses in electricity. The definition is based on 'process house load' specified in Section 2 (2) (a) of public notice no. 541/25 on Electricity Market Rules, in the wording applicable in 215. House load for heat production (HL h ) = Analogous to HL e. Installed capacities = Installed capacities reflect the capacities actually connected in the transmission system and the distribution systems, i.e. the figures do not reflect the sum of the licences awarded for the respective category of electricity. Local consumption = Consumption of generators and entities directly connected to the respective generating plant. Net balance = Net balance of cross-border exchanges of electrical energy in a given period. It is the difference between total electricity imports and total electricity exports in a given period. A positive value denotes electricity imports exceeding exports, and a negative value denotes electricity exports exceeding imports. National gross consumption (NGC) = NNC + consumption for pumping at PSHE + total losses + HL e. National net consumption (NNC) = HD_C at the EHV level + HD_C at the HV level + LD_H + LD_B + consumption of the TSO and DSOs + local consumption + HL h. Net electricity = Gross electricity minus house load for electricity (including losses). Total losses = Losses in distribution system operators' and the transmission system operator's networks.

215 2 Commentary on the year under review Under Section 17(7)(m) of Act No 458/2 as amended (the Energy Act), the Energy Regulatory Office (ERO) publishes the Yearly Report on the Operation of the Czech Electricity Grid for 215. All data is based on information received from licensees. This Report follows up on the yearly reports released in preceding years and provides information about the electricity industry s and, partly, the heating industry s key statistics for 215, including their development over the past ten years. Its respective chapters contain statistics on electrical energy balances for January to December 215 and electricity and consumption by category, including renewable energy sources (RES) and combined heat & power. The Report also contains an overview of the installed capacities in the Czech electricity grid, electricity imports and exports, and some region-specific evaluations. More detailed information can be found in the monthly reports on the operation of the Czech electricity grid, which are posted on the ERO s website. The Yearly Report for 215 is based on the data in the December 215 report and contains some data that is more accurate than in the released monthly reports. Gross electricity totalled 83.9 TWh in 215, down by 2.5% year-on-year, while the country s gross electricity consumption (71 TWh) rose by 2%. The largest year-on-year change in electricity was registered in combined cycle plants, up by 24.7%; their output offset the year-on-year drop in nuclear power plants output by 11.5%. Generation in large, over 1MW hydroelectric power stations decreased again, this time by 11.6% year-on-year. But their in 214 was already evaluated as the lowest over the period under review due to the extremely low water levels in streams. Electricity decreased by 6% overall year-onyear. Electricity in pumped-storage hydroelectric power stations increased by 21.3%. Electricity in wind power plants also rose, by 2.2% year-on-year. Electricity in photovoltaic plants and from biomass, biogas and biodegradable municipal waste slightly increased. Despite gross domestic electricity consumption rising by 2%, the ratio of gross electricity from renewable sources and gross domestic consumption increased slightly by.1 percentage point. The trend of growing electricity from renewable sources has slowed down in the past three years and gross renewable electricity accounted for 13.27% of total consumption last year. As in preceding years, 215 also saw a continuously negative net balance, amounting to 12.5 TWh for the whole year. This implies a year-on-year drop by 23.2% due to higher electricity imports. The annual peak load in the grid was registered on 9 February 215 at 12 noon (1,852 MW) and the annual minimum load on 2 August 215 at 5 a.m. (4,995 MW). The Report also evaluates hourly load and consumption variations, including the structure of the generating capacities covering the peak load and the minimum load. Consumption on the peak load and minimum load days in preceding years is also shown. The Yearly Report also shows the SAIFI, SAIDI and CAIDI supply quality ratios and key technical data on the transmission system and regional distribution systems. The latest map of the Czech electricity grid is attached to the Report. The information for this Yearly Report has been obtained directly from electricity generators and distribution system and transmission system operators; information about renewable energy sources has also been obtained with the help of OTE, a.s. Data sources are shown with the respective tables in the report. Please feel free to send your questions and comments to elektro.statistika@eru.cz. Stránka 4 z 35
