Basic provisions
(1) The installation, operation, operation, control and maintenance of measuring equipment, subtraction and storage of measurement data are the provision of electricity measurements.
(2) Measurements shall determine the quantity of active or reactive electricity supplied and / or withdrawn and its time course.
(3) The direction of electricity flow to the relevant sampling or transfer point of the rated market participant is considered positive. The direction of the flow of electricity from the relevant sampling or transfer point of the rated market participant shall be considered negative.
(4) The following shall be used to measure the amount of electricity and to evaluate the power transferred:
(a) continuous measurement of electricity with daily remote transmission of data (hereinafter referred to as Type A measurement);
(b) other current measurements of electricity (hereinafter referred to as type B measurements);
(c) other measurements of electricity (hereinafter referred to as type C measurements).
(5) For the flow-through measurement mode, the mean power value over the measurement interval shall be recorded on an ongoing basis directly by the measuring device.
(6) Measurement and transmission of actual and contractual values is carried out in winter or summer. The last day when winter time is changed to summer is 23 hours, the first day when summer time is changed to winter is 25 hours.
(7) Measurement data are transmitted in kW, kWh, kVar and kVArh between market participants.
(8) Where, for technical or economic reasons, it is not possible to fit the relevant measurement in accordance with Section 3 at a given sampling or transfer point, the electricity shall be measured in another appropriate way in accordance with paragraph 4.
Measuring equipment
(1) The location of the measuring devices is specified in the connection contract.
(2) In order to ensure the measurement of electricity,
(a) measurement of type A
1. transfer points between the transmission system and foreign systems,
2. transmission points between transmission and distribution systems with a voltage greater than 1 kV;
3. the final customers' demand points with electricity from the transmission system, if the final customer has fulfilled the obligation under Paragraph 49 (2) of the Act,
4. transfer points between distribution systems with a voltage greater than 52 kV;
5. the transmission points of electricity producers with installed power of 400 kW, provided that the electricity producer has complied with the obligation under Paragraph 49 (2) of the Act;
6. final customers' demand points with a voltage of more than 52 kV, provided that the final customer has complied with the obligation under Paragraph 49 (2) of the Act; and
7. final customer demand points with a voltage of 1 kV to 52 kV and a reserved input of 400 kW if the final customer has fulfilled the obligation under Paragraph 49 (2) of the Act;
(b) at least by measuring type B
1. the transmission points of electricity producers with installed power from 100 kW to 400 kW, if the manufacturer has fulfilled the obligation under Paragraph 49 (2) of the Act,
2. final customer demand points with a voltage of between 1 kV and 52 kV including, if the final customer has fulfilled the obligation under Paragraph 49 (2) of the Act, the demand points of final customers with a voltage of between 1 kV and 52 kV inclusive and a reserved power of up to 400 kW,
3. transfer points between different distribution systems with a voltage of 1 kV to 52 kV inclusive; and
4. final customer demand points with a voltage of up to 1 kV, with a reserved power input of 100 kW or with a main security element of nominal current of 200 A from the first change of the electricity supplier, provided that the final customer has fulfilled the obligation under Paragraph 49 (2) of the Act;
(c) at least by measuring type C
1. the transmission points of other electricity producers; and
2. the sampling points of other final customers with the electricity from the distribution system with the installed measurement.
(3) Unmeasured electricity consumption, except for alarm sirens and railway safety devices, must not have a power reserve greater than 1 kW. For non-measured electricity withdrawals, the electricity payment is determined according to the installed power input.
(4) For type A measurements, a maximum deviation of 5 seconds between devices is permitted.
(5) A maximum deviation of 1 minute from the uniform time is allowed for type B measurements.
(6) A maximum deviation of 15 minutes from the uniform time is allowed for type C measurements.
(7) The exchange of measurement equipment owned or withdrawn by the transmission system operator or the relevant distribution system operator shall be carried out by the transmission system operator or the relevant distribution system operator after prior notification to the electricity market participant concerned.
(8) When changing measuring equipment or for new installations, the minimum requirements for the accuracy of the electrometers used and voltage and current measuring transformers shall be as set out in the Annex.
Evaluation and transmission of measurement results
(1) The actual electricity values are:
(a) values measured, calculated on the basis of measurement data, where appropriate;
(b) the agreed replacement values after correction of the erroneous or the lack of values by agreement between the electricity market participants concerned;
(c) measured values in kWh, kW, kVArh and kVar increased in the case of collection or reduced in the case of supply by the relevant price decision of the Energy Regulatory Authority or by the values agreed in the connection contract or in the electricity distribution contract if the electricity supply or supply is measured on the secondary side of the transformer.
(2) The actual value of electricity supplies and withdrawals is the input data for assessing the electricity collection or supply of the market participant. The measurement and transmission of the results of the electricity measurement shall be carried out by the owner of the measuring equipment concerned at the transmission points where the supply and supply of electricity are carried out for several natural or legal persons.
(3) The actual consumption and supply values and other information necessary for the settlement of electricity purchases and supplies are transmitted by the transmission system operator or the relevant distribution system operator to the market operator and provided to the relevant customer or electricity producer.
(4) Measured values of electricity supplies and withdrawals are stored at the transfer point for at least 40 days. The actual values of electricity supplies and withdrawals shall be kept by the transmission system operator or the relevant distribution system operator carrying out the measurement for at least 14 months.

| napětí vyšší než 52 kV primární měření | 0,2 | 0,2 | činná energie, třída přesnosti 0,5 jalová energie, třída přesnosti 1 |
The accuracy class character is a number indicating the limits of the permitted percentage error for all measurement range values at the unit power factor (and for multi-phase electric meters with symmetrical load) if the electrometer is tested under reference conditions, i.e. including tolerances for reference values defined by the relevant Czech technical standard.
