10 Legal framework Law on electric energy The regulation on quality of services of electricity supply and distribution Bilateral contracts of electricity supply The interstate standard on voltage quality (GOST )

11 Continuity of supply Reliability indexes that are systematically monitored by ANRE are SAIDI, SAIFI andcaidi. These indexes are calculated for unplanned interr uptions, longer than 3 minutes, which take place in the medium voltage (10 kv) networks.

12 Continuity of supply According to the regulation on quality of services, approved by ANRE, all the DSO need to improve the level of SAIDI every year. The established levels of SAIDI for the period are the next: hours, hours, hours, hours, hours. In case if a DSO doe es not achieve the established level l of SAIDI, ANRE has the right to apply penalties by reducing the tariff.

13 Continuity of supply Unplanned interruptions are divided into 4 groups, depending on the cause of interruption: FM interruptions, caused by special meteorological conditions (the wind speed is more than 30 m/s and/or the ice deposit is more than 20 mm) or force majeure; IC interruptions, caused by incidents in consumer s installations; AT caused by actions of a third party (traffic accidents, fires in the protection zones of electric lines and other distribution installations, damages of TSO s equipment etc.) AC - other causes failures in the distribution network, which the DSO is responsible for. Reliability indexes, which DSO may be penalized for, are calculated for interruptions, marked with AC.

19 Continuity of supply Duration of one planned interruption: 24 hours (interruptions, linked with overhaul of the distribution networks); 12 hours (other planned interruptions); Duration of one unplanned interruption: 24 hours (in case of difficult accidents); 16 hours (interruptions, whichh take place during the night, due to failures in the medium voltage (10 kv) networks); 6 hours (urban area), 8 hours (rural area) other incidents;

22 Voltage quality For measuring the voltage quality, in Moldova is used the standard d GOST- Electromagnetic Power quality. compatibility of technical equipment. Power quality limits in public electrical systems. This is an interstate standard, used in the former USSR, that establishes the quality parameters of electric energy.

23 Voltage quality According to the Regulation on quality of services, approved by ANRE, in case of consumers complains, regarding the voltage quality, DSO has a limited period of time to r estore the voltage quality: Consumers calls: 24 hours after the call, in case of overvoltage or repeated voltage dips; Written complains: 5 days after receiving the complain if for restoring the quality it is necessary to execute some simple activities, like redistributing of electric load on phases, regulating the voltage from power transformers etc.; 30 days in case of increasing of existent networks capacity or the necessity to replace a power transformer etc; 60 days in case of necessity to elaborate projects and building new line sectors; If DSO does not solve 10% of customers complains in fixed terms, ANRE can reduce the tariff.

24 Commercial quality ANRE monitors the following situations, regarding commercial quality: Notifying of planned interruptions (3 days before interruption for small customers and d7d days before interruption i for customers with power more than 100 kw). Issuing of prior connection approvals (15 calendar days) Contracting of electricity supp ply (2 working-days for householders and 5 working-days for other consumers); Connecting to distribution network (3 calendar days). If DSO doesn t respect this term, the consumer can demand a compensation (25% of the connection fee for every overdue day). Reconnecting of a customers installation to the network (2 workingdoesn t respect this term, the consumer can demand a compensation (25% of the reconnection fee for every days). If the supplier (DSO) overdue day). Proceeding of consumers written petitions (not more than 30 calendar days)
