Latvenergo Group is the leading producer of electricity and thermal energy in Latvia.

Latvenergo Group has a balanced and environmentally friendly energy generation portfolio, consisting mostly of hydropower plants and highly efficient combined heat and power plants.

Most of the electricity and thermal energy is generated by the three Daugava hydropower plants (HPPs) and two combined heat and power plants (CHPPs) of Latvenergo AS. Energy is also generated by Liepājas enerģija SIA, Aiviekste HPP and Ainazi Wind Power Plant (WPP).

Share of energy resources in the electricity output

Daugava hydropower plants

The Daugava HPPs are the biggest hydropower plants in the country, providing a large share of renewable energy not only in the Group, but also in Latvia as a whole.

In 2022, the electricity output at the Daugava HPPs did not significantly change: 2.7 TWh of electricity were generated, which constituted 70% of the Group’s total electricity output.

2,670 GWh

In 2022, investments in the Daugava HPPs’ assets amounted to EUR 12 million, including EUR 4.2 million invested in the programme for the reconstruction of hydropower units, which will ensure their operation for more than 40 years. The programme provides for the reconstruction of 11 hydropower units that have not been reconstructed yet, of which eight were commissioned by the end of 2022. The total cost of the programme is expected to be around EUR 260 million. Investments of EUR 200 million were already made by the end of 2022.

Replacement of outdated hydro turbines contributes to an increase in the Daugava HPPs’ capacity, efficiency rate and a decrease in water consumption per 1 kWh. This promotes reliable, efficient and competitive operations of the Daugava HPPs within the overall energy system and in the electricity market. More efficient use of water resources mitigates the negative impact of the Group on climate change. In 2022, each megawatt hour of electricity generated by the Daugava HPPs reduced CO2 emissions by 0.366 tonnes, assuming that this energy would otherwise be generated in condensation mode at combined heat and power plants by using natural gas as fuel.

Investments in the Daugava HPPs

The ability of the Daugava HPPs to generate electricity depends on the water inflow in the Daugava River. During the flooding season, it is possible to cover the demand for electricity of all Latvenergo Group’s customers and trade the excess on the Nord Pool exchange. Outside the season, the Daugava HPPs provide for the possibility to accumulate water and adapt generation of electricity when the demand and prices on the exchange are higher.

Plavinas HPP

Start of operations - 1965
Capacity - 908 MW
Hydropower units - 10
Energy source - water

Plavinas HPP is the largest hydropower plant by installed capacity in the Baltic states and one of the largest in the European Union. It plays an important role in ensuring the stability of the Baltic power system in the event of unplanned outages or accidents at base plants. Plavinas HPP also serves as a synchronous compensator for voltage regulation in high voltage electricity networks.

Riga HPP

Start of operations - 1974
Capacity - 402 MW
Hydropower units - 6
Energy source - water

Riga HPP is the newest of the Daugava hydropower plants. It also serves as a synchronous compensator for voltage regulation in high voltage electricity networks. The reconstruction of the Riga HPP was completed in 2022.

Kegums HPP

Start of operations - 1939
Capacity - 248 MW
Hydropower units - 7

Kegums HPP is the oldest Daugava hydropower plant. It consists of two separate power plants built at different times on the right and left banks of the Daugava River.

The combined heat and power plants of Latvenergo AS

High prices for natural gas and emission allowances led to a drop in CHPP electricity production of around 40% in 2022. The CHPPs produced 1.1 TWh of electricity, which accounts for 29% of the total electricity production of the Group. The amount of thermal energy generated by the CHPPs was 1.5 TWh, a 15% decrease compared to the previous year. The decrease is mainly due to warmer weather in the 2022 heating season. The heat produced is sold at regulated tariffs to Rīgas siltums AS, as well as to the local external heat users of CHPP-2.


Electricity output at CHPPs

1,123  GWh

Thermal energy output at CHPPs

1,531 GWh

The upgraded CHPPs of Latvenergo AS are mostly operated in the highly efficient cogeneration mode in accordance with the thermal energy demand, which in turn depends on weather conditions, the duration of the heating season and competition in the thermal energy market. The operation of these plants can be flexibly adjusted to the electricity market conditions and guarantees a significant baseload electricity capacity for Latvia. Both CHPPs can cover Latvian electricity consumption almost completely in circumstances where, due to certain factors, electricity imports from foreign countries are limited. In response to the energy crisis, the CHPPs also used diesel as an alternative fuel to natural gas for thermal energy generation in 2022; 11% of the CHPPs’ thermal energy output was produced with diesel.

In March 2021, the CHPP-2 heat storage system was commissioned; it is the largest project of its kind in the Baltics. The 17,800 m3 heat storage tank enables accumulation of thermal energy generated in cogeneration mode and optimises the adjustment of the CHPP operating modes to changing market conditions and to cover peak loads. In 2022, the system achieved primary energy savings of more than 300 MWh and CO2 savings of almost 1,100 tonnes. In addition, it increases the security of the heat supply of the Riga district heating system on the right bank of the Daugava.

Creation of a heat storage system at CHPP-2 generating facility

The construction of a heat storage unit in the territory of CHPP-2 of Latvenergo AS has completed becoming the largest and the only heat storage unit in the Baltic countries with the volume of heat

carrier of 18 thousand m 3. An extensive and modern solution will ensure more efficient use of heating fuel in the country, reduce consumption of energy sources and increase competitiveness of CHPPs.
