JSC "Sadales tīkls" systematically updating and improving the electricity network in the entire territory of Latvia, increasing the reliability and quality of electricity supply to residents and businesses. To ensure reliability, efficiency of grid to JSC "Sadales tīkls" to provide high quality services for energy distribution, necessary to carry out maintenance checks in a certain amount of timely update of the power grid, like any other engineering installation and to introduce modern and reliable installations and technologies on the power grid. The elements of supply, including cable lines that are, on average, 50 years old, so a timely update is the main condition allowing to ensure the long-term customers with high-quality and uninterrupted power supply, and to reduce the impact of the various external risks to continuity of supply.
To improve the reliability and quality of electricity supply to customers in Liepaja, JSC "Sadales tīkls" annually provides volumetric reconstruction of the power grid in the city and projects on the restructuring. Recently in Liepaja ended reconstruction built in 1983 substations "Zaļā birzs" and "Ezerkrasts" capacity 110/20/10kV (kilovolts), which carried out the construction of new buildings for switchboards with a capacity of 10kV and 20kV, and this year at the substation "Ezerkrasts" was established by the quenching coil. In General, both substations provide electricity to over 23,000 customers, so its reconstruction is so important in the long term to provide households and businesses Liepaja uninterrupted power supply and voltage quality. After the reconstruction of the substation customers will have the opportunity in the future to implement new electrical connections and enhance the existing capacity of the network connection. Only the reconstruction of the substation of JSC "Sadales tīkls" has invested 3.1 million euros.
Taking into account the fact that the grid needs to be gradual and timely updates, JSC "Sadales tīkls" in Liepaja, Latvia is implementing a restructuring of the middle cable lines 10kV and 0.4 kV low voltage, and the reconstruction of transformer substations. This year in Liepaja plans to build new cable lines of medium voltage with a length of 8.5 km and to reconstruct 10 transformer substations, investing in updating and improving the mains 591,1 thousand euros.
This year, the restructuring of the power lines carried out in the Karosta district, and work on updating the mains continue in ziemeļu suburb. Karosta is one of the projects implemented on the street Laboratories. In the framework of this project JSC "Sadales tīkls" has carried out reconstruction built in 1975, cable lines of medium voltage and built a new cable line medium voltage 10 kV with a length of 2.2 km, as well as power line low voltage 0.4 kV with a length of 0.1 km along the St. Laboratories and reconstructed transformer substation. Before the restructuring of the power grid access of employees of JSC "Sadales tīkls" for the cable line was difficult, as she crossed the Park Beberlini and forest area. It was not possible to access cable lines with the use of specialized equipment, and maintenance and repair of inconvenience to employees, it required more time to restore supply to customers in case of damage to the network. Often damage power lines, which crossed the Park Beberlini, arose in the implementation of economic activities, when workers with inconsistent operations of excavation damaged cable line, causing losses of JSC "Sadales tīkls" and causing power outages for customers. During the reconstruction works on the mains was installed the power switches of remote control, which will enable the staff of JSC "Sadales tīkls" to realize the remote network control and to switch the mains in case of damage. Power switches the remote control allows in case of damage to disable only the damaged portion of a power line, the power line, so the controllers of the PLC immediately remotely to switch the power lines, reducing the time of interruptions in power supply customers. Reconstruction of the outlet in Karosta this year and performed on the streets Piestatnes and Pulkveza Brieza street. During the reconstruction works the JSC "Sadales tīkls" for 1 km replaced built in 1975 cable line medium voltage 10 kV and built a new cable line voltage low long and 0.4 km. After the restructuring of power lines will improve the quality and reliability of electricity for 2249 customers, electricity supply which delivers electricity on the streets of Laboratories, Piestatnes and Pulkveza Brieza street, and the staff of JSC "Sadales tīkls" will be able to receive much-needed quick access to supply infrastructure.
The restructuring of the power grid in ziemeļu suburbs will continue. One of the projects implemented in the vicinity of a street O. Kalpaka, Strazdu, Silky, where over 1 km updated cable line medium voltage 10 kV and rekonstruiruet 3 transformer substations, in turn, another project in vicinity of streets Piltenes, Zelma and Schedes includes upgrading the cable lines of medium voltage 4 km in length and reconstruction of the transformer substation. After the restructuring of the grid will increase the reliability and quality of electricity supply in more than 4,600 households and businesses, with a reduction in the number of power outages caused by outdated technological damage of cable lines.
This year reconstruction of transformer substations are also carried out on streets of Liepaja Krum and vanes. During the reconstruction works at transformer substations were installed the power switches of remote control, which will enable the staff of JSC "Sadales tīkls" to realize the remote network control and to switch the mains in case of damage, thus reducing the time of interruptions in power supply customers. In subsequent years, JSC "Sadales tīkls" is also planning the implementation of projects to upgrade and improve, enhancing the quality of services provided to customers.
