Improving Investment Planning Through the Implementation and Enforcement of Quality of Service Standards

It ensures that customers receive safe and reliable electric service at just and reasonable rates/tariffs. QoS monitoring and respective indicators/metrics are divided into three broad areas: Continuity of Supply (CoS), Voltage Quality (VQ), and Commercial Quality (CQ). CoS concerns interruptions in electricity supply, including the customer average interruption duration index (CAIDI) and system average interruption frequency index (SAIDI). These indicators are used to measure the reliability of the electricity supply and identify areas for improvement. VQ concerns a wide range of disturbances and deviations in voltage magnitude or waveform from the nominal values. This includes amplitude deviations from nominal on a weekly basis with a weekly aggregate result, frequency deviations from nominal on a weekly basis with a weekly aggregate result, and root mean square (RMS) values. CQ concerns transactions between electricity companies and customers, including the use of supervisory control and data acquisition (SCADA) systems. This area focuses on ensuring that customers receive accurate and timely information about their electricity supply. The document presents a unified common QoS framework, which includes data collection templates, a common set of metrics and indicators, and methods for establishing performance benchmarks. This framework aims to establish a common set of metrics and indicators for all three areas of QoS monitoring. The framework is based on best practices from the European Union (EU) and the United States, and is designed to be adaptable to the specific needs of each country. It includes a set of standardized data reporting templates, which can be used to collect and analyze data on QoS indicators. The document also presents a set of recommended minimum number of indicators to be monitored per type of service, as well as a set of extended indicators for all different types of service. These indicators can be used to identify areas for improvement and to develop targeted investment plans. The framework is designed to be used by national regulatory authorities (NRAs) from the Europe and Eurasia (E&E) region, and is intended to improve the quality of service for end-users. It is based on a collaborative effort between NRAs and distribution system operators (DSOs) to map local QoS practices and internationally followed best practices. The document concludes by presenting a set of roadmaps for selected NRAs, which outline the steps needed to implement the QoS framework. These roadmaps take into account the specific barriers and issues faced by each NRA, as well as the availability of equipment and resources. Overall, the document presents a comprehensive framework for QoS monitoring and performance benchmarking in the electricity sector. It is designed to be adaptable to the specific needs of each country and is intended to improve the quality of service for end-users.
