Rīgas BioEnerģija is contributing to a more sustainable Riga. In the capital of Latvia, the transition towards a more sustainable, efficient and resilient district heating system is already well underway. SIA “Rīgas BioEnerģija” plays an important role in this transition. By producing renewable heat from locally available biomass the plant contributes to the reduction of the city’s dependence on fossil fuels.

A more Sustainable Riga: From an Ambitious Idea to 96 MW of Renewable Heat Capacity

Rīgas BioEnerģija was established on 22 October 2014 with a clear objective: to develop two modern biomass boiler plants on the right bank of the Daugava River in Riga.

The project was therefore initiated to increase the share of renewable energy resources in Riga’s district heating system, diversify the energy mix and reduce dependence on natural gas.

Today, the two plants provide Rīgas BioEnerģija with a combined installed thermal capacity of 96 MW, making the company a significant producer of renewable heat in Latvia.

Rīgas BioEnerģija: Turning Biomass into Efficient District Heating 

Rīgas BioEnerģija produces heat in two modern biomass boiler plants connected to Riga’s district heating system on the right bank of the Daugava River.

Each plant operates two biomass boilers with a nominal thermal capacity of 20 MW each. The primary fuel is wood chips – a renewable biomass resource that enables the company to produce heat while reducing reliance on fossil fuels.

Energy efficiency is an integral part of the plants’ design. For thus reason, each boiler plant is equipped with flue gas condensers providing an additional nominal thermal capacity of 4 MW each. By recovering heat from the flue gases, this technology allows more useful energy to be obtained from the biomass fuel. Moreover, the technology improves the overall efficiency of heat production.

The combination of renewable fuel, efficient heat recovery and advanced emission control technologies enables Rīgas BioEnerģija to provide reliable and efficient heat while contributing to a more sustainable urban energy system.

Strengthening Riga’s Energy Resilience through Bioenergy

The role of bioenergy extends beyond renewable heat production. Increasing the use of renewable energy resources in district heating contributes to a more diversified energy mix and helps reduce dependence on natural gas and other fossil fuels.

This is particularly important in a city such as Riga, where the Baltic climate creates substantial heating demand throughout the colder months of the year. Reliable renewable heat production therefore contributes not only to sustainability objectives but also to the resilience and security of the city’s energy supply.

Rīgas BioEnerģija is contributing to a more sustainable Riga. The project demonstrates how modern biomass technologies can be successfully integrated into a large urban district heating network, combining renewable energy production with high efficiency, reliable operation and advanced environmental technologies.
