#### 5.2.1 BTS (BTS)  
If continuous metering is installed on MP type C metering to the extent that it is gradually being built, remote readings will be taken at least at 95% of the sites and possibly more. Therefore, the mobile operator and its data transmission via BTS will be very important. Legal and contractual obligations are as follows: In case of a BTS failure or more, or, for example, if the operator carries out some modifications to the mobile network in a certain area and the meters stop being read as a result, there may be a violation of Decree No 359/2020 Coll., SS 5, SS 6, SS 8 because the distributor would not fulfil the obligations of reading and timely transmission. In addition, there may be a breach of Decree No 540/2005 Coll., SS 14, SS 15, SS 16, which provides for the quality of the service supplied. The number of such cases may range from hundreds of points of consumption to several thousand due to the expected installation of a larger number of meters with remote readings. The risk is, therefore, assessed as high. In a very extreme case, a violation of Act No 458/2000 Coll., Section 11 and Decree No 408/2015 Coll. Management and operation of the organization could occur: as the BTS outage of the mobile operator is an external service, and so communication with external suppliers always takes longer than internal communication, there is also a form of uncertainty for the operator, as communication may not not be repaired in time for sites where legal deadlines need to be met. Cases where there is a communication outage with a large number of sites are very burdensome for the distributor. As it is assumed that large-scale outages cannot be covered by field staff and sending data by an alternative route, the risk of CEZ Distribuce, a.s. is high. Loss of credibility is also a concern; in this case, it is considered that loss of credibility will be at an approximately medium level. The outage should never fully affect all the points of consumption on one BTS; furthermore, it is from an external supplier, and the impactwill be felt much more by the external entity than by CEZ Distribuce, a.s., itself, which will not be fully responsible for the outage. In terms of financial loss/fisruption of activities, if we assume that an outage of services for some 1000 MP, which would require the loss of several BTS, according to the Czech Telecommunication Office, yhid eoufl numbrt about 16,000 for 4G networks throughout the Czech Republic. That works out to about 1 BTS per 60 users. CEZ Distribuce, a.s., would be most vulnerable to this outage during the period at the beginning of the month, when it is necessary to provide data to EMO by a certain time. For Type C measurements, the same timeframes as for other continuous measurements will apply. Hence, data must be delivered within 7 working days, 18 h. If we assume that the problem would still occur in 1000 MP on the 7 th working day after 18 h, then the penalty would be up to 300,000 \(\upcels\). Regarding the provision of essential services, if there is a communication outage due to problems in the mobile network, it should never affect more than a few thousand people, and this should only occur in a very limited number of cases. Following the experience of the pilot projects, such a large-scale outage can be expected once a year. In the area of critical service provision, this is rated as medium risk due to the small number of sites that will be affected. A comprehensive assessment of the risks and parameters of data availability and maturity is presented in Table 13.
