The successful implementation of smart metering in the European Union (hereinafter – EU) depends on criteria that are mostly determined by the Member States themselves. These criteria cover the regulatory framework and legislation necessary for the establishment and functioning of the smart metering system, the fulfilment of technical and commercial conditions, as well as the security of data collection, archiving and use. The introduction of the smart metering in different Member States has started at different times. In Latvia, its reference point was 2004, when the goal was set to maximise the use of telemetry in the natural gas metering. Currently, in the Latvian natural gas distribution system about 85 % of all consumption data are automatically processed.One of the most important components of the smart natural gas metering is natural gas commercial metering devices (hereinafter – smart meters). They differ in both the principle and type of operation. Depending on the technology used, the metering range changes, and thus the accuracy of the measurements.The article addresses some issues of further successful implementation of smart metering in the Latvian natural gas sector, as well as the measurement accuracy for smart natural gas meters.

“…Smart natural gas metering meets requirements for fast and accurate collection, analysis and archiving of the natural gas consumption data, as well as provides opportunities for SSOs to perform more effective evaluation and planning of the natural gas supply system development in various regions of Latvia and other EU Member States. It may also contribute to the achievement of energy efficiency and system security targets [33], [34], which ensure sustainable economic development and prevention of further climate change. Moreover, with the introduction of SGD, costs for smart metering and data processing, archiving and storage are expected to decrease at a rate of approximately 7 % per year.…”

A necessity to reduce greenhouse gas (hereinafter – GHG) emissions and energy import dependency, while coping with increasing energy demand, affordability issues and many other factors, causes the European Union (hereinafter – EU) energy policy makers to identify development trends that would help harmonize future energy market and technological changes with ever growing pressure of universal data processing digitalisation. In order to stimulate data processing digitalisation in energy, the European Commission has proclaimed a support to the development of all kind of the smart energy systems, where simultaneous use of the natural gas and renewable gases (hereinafter – RG) will play one of the major sustainability ensuring roles. Firstly, it will help achieve designated energy efficiency goals and, secondly, enable cost saving synergetic solutions at the early stages of the energy supply chain decarbonisation.Synergy of the natural gas and RG emphasises the need for a modern, smart and sustainable energy infrastructure to allow developing more flexible back-up and balancing power capacity, storage solutions and innovative demand-response mechanisms.This paper addresses some trends in development of the smart gas distribution (hereinafter – SGD) as part of the smart energy systems both in the EU and Latvia, with a particular focus on smart energy concepts, smart gas metering and grid modernisation.

The Latvian natural gas system is interconnected with transmission networks located in Lithuania, Estonia and Russia. Natural gas commercial metering is provided by GMS “Karksi” (Estonia) and by GMS “Kiemenai” (Lithuania). Natural gas is supplied to all larger urban areas in Latvia. Natural gas is supplied to Latvia along the Latvian–Russian pipeline only during the warm period of the year (April–September), and it is accumulated in the underground gas storage facility in Incukalns. During winter, gas from the underground facility is delivered to Latvian customers, as well as transmitted to Estonia and back to Russia. There is also a connection to Lithuania. Out of the gas supply disruption risks that are assessed at different levels, the essential one with a trans-border impact potential consists in the insufficient technical capacity of Incukalns UGS. Given the current technical possibilities, IUGS cannot pass the gas volume required for the Baltic States to compensate the gas supply deficit. The paper performs system recovery analysis after selected critical events. The paper provides a report describing the steps to be followed in order to restore the gas transmission system to normal operation after selected critical events. A very significant region of the power system of Latvia is the central part of Latvia and Riga region, where both of Riga CHPs, as well as Riga HPP, is located. The restoration time of the gas system of Latvia depends on the gravity of the situation and damage in the gas system and may range from several hours to several days.
