District heating 

Most environmentally friendly heating solution for cities and district areas

District heating ensures fuels get used efficiently and significantly improves air quality in cities by reducing emissions of fine particles and dust. When, for example, extending the property, district heating can be flexibly scaled, there is no need for any large additional investments to an existing heating solution. District heating and cooling are safe, convenient and clean choices that offer energy security.

A sustainable, cost-efficient and safe district heating solution is a convenient solution for customers. There are minimal maintenance costs, low initial investments for connection, and professional  customer service – customers don’t need to worry about regular maintenance and inspection. We have already successfully provided district heating services in Baltic countries.

District heating is a centralized system that produces and distributes heat to multiple buildings or residences from a central source. Usually, hot water or steam is generated in a central facility and then circulated through a network of pipes to provide space heating or hot water for various users. This centralized approach enhances energy efficiency and facilitates the integration of various heat sources into a sustainable heating solution.

District heating is commonly found in parts of Europe, particularly the Baltic and Nordic countries, Germany, and the Netherlands. Gren has more than 20 years of experience in serving customers and partnering with towns and cities by developing sustainable generation assets and efficient and reliable district heating networks.

Gren uses proven technology to deliver clean and secure heat and power, building resilience to climate change and future-proofing our homes, industries, and public services.

To achieve Net Zero targets

District heating is an internationally proven way for decarbonising heat at scale and will need to see significant growth if we are to successfully decarbonise our towns and cities. Driving forward low-carbon energy solutions such as district heating makes achieving net zero considerably more achievable as we drastically reduce the use of fossil fuels.

District heating networks can also support system flexibility where they have centralised thermal storage attached or use multiple heat sources, allowing them to shift demand. Together with opportunities to utilise waste heat, this can help achieve efficiencies across the power system and reduce emissions.

Many different technologies can provide the input to a heat network, including power stations, Waste-to-Energy facilities, industrial processes, biomass and biogas fueled boilers, and Combined Heat and Power (CHP) plants – which can include gas-fired units, fuel cells, heat pumps, geothermal sources, electric boilers and solar thermal arrays. All of Gren’s assets use locally sourced fuels.

District heating delivers low-carbon heat

District heating is a system that uses a singular central heat source to distribute hot water to multiple individual dwellings through a network of insulated pipes. The structure is usually used to fulfil heating and hot water requirements in apartment complexes and in large-scale buildings associated with, e.g., educational and commercial operations. Because district heating efficiently delivers low-carbon, cost-effective heat, it is a vital solution in an accelerated move towards low-carbon energy systems.

Renewable energy resources for heating

Our combined heat and power plant in Jelgava uses local renewable energy resources – primarily wood chips – to provide district heating to customers. The largest plant of its kind in Latvia has improved the overall efficiency and security of district heating, reducing CO2 emissions from heat production by 90%.
