Power Supply

The city of Riga receives power primarily from the electric power networks of the unified energy system – two 330 kV substations located in Riga (Imanta, Bišuciems), twenty-four 110 kV substations (Andrejsala, Šķirotava, Krasts, Grīziņkalns, Jāņciems, Centrālā, Mīlgrāvis, Sarkandaugava, Vairogs, Purvciems, Hanza, Vecmīlgrāvis, Bastejkalns, Salamandra, Iļģuciems, Daugavgrīva, Bolderāja I, Bolderāja II, Zunda, Tīraine, Mārupe, Torņakalns, Matīss and Zolitūde) and two thermal power stations (TEC-1,TEC-2).

JSC Latvenergo planned construction and reconstruction works for the period of up to 2012 Construction and reconstruction terms of power supply facilities (especially for construction of the 110 kV substations and lines) are related to development of the largest consumers and the city infrastructure facilities. Possible location of new  330 kV and 110 kV substations has been taken into account in the Riga Development Plan up to 2018.

Heat Supply

The Riga Heat Supply Development Concept for the Period of 2006-2016 stipulates the chief trends of heat supply development, which must be observed when planning and implementing heat supply provision measures, modernising heat supply systems, including heat sources, improving quality of services, increasing energy efficiency, planning and implementing of energy consumption reduction, as well as formation of tariffs. Modernisation and transfer to cogeneration systems, which are more energy efficient, takes place gradually. Municipal heating in Riga is provided by JSC Rīgas Siltums. The Riga municipal heating system consists of two main parts, namely the Left Bank and Right Bank heat supply systems. The total length of the heat supply networks in Riga is 732 km, of which the largest part of the network (543 km) is formed by the Right Bank system. Riga consumes 52 % of the thermal energy delivered in the country. By performing rehabilitation of the heat supply system in conformity with the first Riga Heat Supply Development Concept for 1997-2010, putting in order the consumers internal heat supply systems, training service staff and stabilising tariffs, a significant work has been already done in Riga to bring the municipal heat supply system closer to its classical variant. About 80% (74% according to the 2004-2005 data) of total residential areas are technically provided with the municipal heating supply.

Gas Supply

Gas supply in Riga and the surrounding areas is ensured by three gas regulation stations (hereinafter – GRS): GRS “Rīga – 1”, GRS “Rīga – 3” and GRS “Ziemeļi”.
The total length of the gas pipeline distribution systems in Riga and its environs is about 2.7 thousand km.

Water Supply

Municipal water supply services in the city territory are provided by the municipal company Rīgas ūdens. It provides municipal services to approximately 90 % of residents. Riga has one ground water source – the Daugava River and seven underground sources of water. The total supply of the water sources is approximately double the current demand. Therefore, they supply various amounts, depending on the season and performed repair works at the water sources and the city networks. Jaunciems, with the environs, has its own water supply system (for about 2500 residents). Water is obtained from artesian wells with the help of pumps. Prior to delivery to the consumers, water has iron removed and is softened. During the recent years, large investments were made into modernisation of the Daugava water source treatment plants, including for the treated water ozonizing. As a result of these works, the Daugava station water complies with all EU quality indices. As to the underground water quality, not all water sources comply with the EU standards with regard to the iron and manganese content.  The total length of the water-supply system is 1392 km. Approximately 90% of the Riga water-pipes are made of metal (cast iron or steel), without internal anticorrosive coats.

Household Sewage

Municipal sewage services in Riga are provided by the municipal company Rīgas ūdens. These services are used by about 81% of residents. The service is available almost in all residential districts of the city, except for some districts of low-rise private residential houses. Waste water in Riga is collected by using gravity-flowing sewerage networks. The collected waste water is pumped, with the help of a pumping station, to the Daugavgrīva waste water treatment plant (hereinafter – WWTP) located in the northern part of the city. In 2008 WWTP Daugavgrīva treated 58 539 178 m³ of waste water, of which 57 219 319 m³, or 156 765 m³/day on average, were from Riga and the rest from Jūrmala. It included 9 236 935 m³/g of rainwater. Following the observed reduction of the waste water amount in the 1990s, the waste water amount has increased by 9% in comparison with 2006.
The total length of the sewage network is 1078 km.

Telecommunications

The electronic communications network – broadcast systems, commutation and routing devices and other resources, which allow transmitting signals, irrespective of the transmitted information type, by using wires, radio waves, optical or other electromagnetic devices through networks. Regardless of the fact that the electronic communications network covers the city almost entirely, development of some territories is possible, resulting in the necessity to build new electronic communication networks and reconstructing the available ones.
