“…Taking into account that the natural gas supply systems of the neighbouring countries have their own interconnections with Russia and that there is a liquefied natural gas terminal in Lithuania, the potential change of the gas supply direction to ensure reverse supply of natural gas would have minimum impact on the natural gas supply reliability in the neighbouring member states; • In summer, there is a possibility to interrupt the supply of natural gas from Russia via the Valday-Pskov-Riga gas pipeline and to rearrange Incukalns underground gas storage to pumping-out mode and ensure the supply of natural gas to the consumers in Latvia without significant influence on the natural gas supply reliability in the neighbouring member states; • Regarding the blind-end gas pipelines (Riga-Daugavpils, and Iecava-Liepaja), the situation depends on the possible location of the damage; the influence is mainly determined by the actual natural gas demand, the gas pressure in the disconnected gas pipeline section and the total remaining natural gas reserve amount. This solution leads to the risk of an increased influence on the natural gas supply systems of the neighbouring member countries; • Depending on the extent of damage, the T.D.Williamson gas pipeline blocking system can be used, building a local bypass line around the damaged place to ensure natural gas supply as a temporary arrangement, with minimum influence on the natural gas supply reliability of the neighbouring member countries; • Within approximately 24 hours, it is possible to ensure supply of liquefied natural gas tanks from Poland and other producers of liquefied natural gas [8], [16], [17].…”

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.

“…An illustration of the changeability of the processes is provided in Figure 2. The task becomes simplified if a hypothesis regarding the stationary nature of the stochastic processes is assumed [28,40]. In this case, it becomes possible to use the historical data on the calculation or measurement results of the input processes: generation WGH, consumption WCH, and price CH.…”

This article analyses the influence of supporting scheme variants on the profitability of a projected investment of residential photovoltaic systems. The focus of the paper lies in evaluating the feasibility for the power system of solar power generation technologies to achieve a balance between energy generation and support costs in a more efficient way. The case study is based on a year-long time series of examples with an hourly resolution of electricity prices from the Nord Pool power market, in addition to the power demand and solar generation of Latvian prosumers. Electric energy generation and the consumption of big data from more than 100 clients were collected. Based on these data, we predict the processes for the next 25 years, and we estimate economic indicators using a detailed description of the net metering billing system and the Monte-Carlo method. A recommendation to change the current net system to a superior one, taking into account the market cost of energy, concludes the paper.
