In Latvia heating is provided through district heating systems, local heat supply and individual heat supply. Heat energy is produced in boiler houses and co-generation stations (CHP plants). Over the past 10 years, the distribution of heat produced in boiler houses and co-generation stations has changed significantly. According to figures from the Ministry of Economics of Latvia, the share of thermal energy produced in co-generation stations in 2015 reached 74.5%.
In 2015, heat energy was generated by 618 boiler houses with an installed heat output of 2524 MW and 183 CHP plants with an installed electric capacity of 1275 MW. Most of the heat generated in district heating systems is produced in Riga, the capital. In 2015, 3598 GWh of thermal energy or 50.9% of the total produced thermal energy were produced there and 991 GWh (14%) in the region surrounding Riga (Pieriga). Moreover, 698 GWh were produced in the Latgale region (9.9%), 684 GWh in Kurzeme region (9,7%), 612 GWh in Zemgale region (8.6%) and 489 GWh in Vidzeme region (6.9%).
The central heating supply customer structure has not changed in recent years, with central heating accounting for 65-70%, hot water supply for 30-35%. The main consumers of heat energy are households. In 2015, 5862 GWh of thermal energy were consumed. The total final consumption of district heating energy for households was 3917 GWh, for the commercial and public sectors 1453 GWh, for industry and construction 403 GWh and for agriculture 89 GWh.
Fuel-wood and natural gas are fuels which are mainly used in the production of heat energy from boiler houses. It is essential that the share of local and renewable energy (fuel-wood) increases each year, reducing the proportion of natural gas. In 2012, 37.8% of heat energy was produced from fuel wood, but 58.6% from natural gas in boiler houses, but in 2015 the share of natural gas has decreased by 20.6%, while the share of fuel wood has increased by 23%.
Natural gas is used as the main fuel for electricity and heat production in CHP plants. In 2015, 78% of electricity and 68% of thermal energy were produced in CHP plants using natural gas. The number of biomass heat sources has increased 2.5 times, and the installed capacity has tripled in 2014 compared to 2007. The total installed chip boiler power tripled to 819 MW.
According to the data of the Central Statistical Bureau, the consumption of fuel chips in Latvia in the last eight years (from 2008 to 2016) has increased 3 times, the consumption of wood residues has increased 1.5 times, while wood consumption has decreased 1.5 times. In 2017 there were 615 boiler houses in Latvia, of which 333 were using biomass as fuel. In 2017, 50 co-generation stations were operating in Latvia, in which biomass (chips and wood) was used. In total there are 204 co-generation stations.
Replicable DHS demo cases
The tailor made Capacity Building programme for Latvia covers training topics identified by Latvian DHS operators and staff during the needs assessment phase. The highest priorities have been given to RES and EE topics including waste to energy aspects as well as to technical topics and organisational topics. Top priority topics has also been identified in financial and management topics. The trainings have been evaluated through anonymous questionnaires by the trainees.
Country project partner
The Zemgale Regional Energy Agency (ZREA) is an NGO facilitating the improvement of energy efficiency in the public and private sector and providing information on the issue for residents. It was initiated by several municipalities, a district heating and a housing maintenance company, as well as the regional innovation and NGO support centre. ZREA has the responsibility for promoting the project on social media and the implementation of DHS pilot projects in Latvia.
The purpose of this Service Pitch Book is to relay the availability of replicable, bankable examples of DH-retrofits for both energy efficiency (EE) and integrating more sustainable energy sources (i.e. RES and/or excess heat, ExH), as well as providing information about national contexts, especially useful to audiences outside a particular country. It highlights the pilot DHSs which have been actively participating in KeepWarm’s activities, giving them visibility as well as stimulating networking opportunities to reach out to them directly for improving DH even further.
This Showroom has been translated into the languages of KeepWarm project partners. Please find here the Latvian version.
KeepWarm Guidance Document
This guidance document has been created as a means of helping you navigate some of the key issues involved in upgrading your district heating (DH) by using more sustainable energy sources, namely from a variety of viable renewable energy sources and/or excess heat harvestable from industrial/commercial processes. Integrating and fully-switching to these greener DH alternatives makes sense not only at an operational level, but is greatly supportive, if not essential, for the successful implementation of a variety of Europe’s flagship policy initiatives.
The translated version of this Guidance Document is currently being prepared.
