Market environment
Primary markets
Steady Energy’s primary target market consists of district heating companies in European cities that are large enough to support at least one reactor, broadly corresponding to cities of around 50,000 inhabitants or more, with an annual heat demand above 300 GWh.
Steady Energy's four priority markets in district heating are Finland, Sweden, Poland and Czech Republic. These markets are characterised by established district heating infrastructure, strong decarbonisation pressures, and a relatively favourable degree of public and political acceptance of nuclear energy. Heat demand in these countries has remained relatively stable over the last 15 years, with annual variation mainly explained by weather conditions. Together they represent approximately 30 per cent of total European district heating demand of approximately 500 TWh annually.
Steady Energy’s serviceable addressable market in the priority markets is estimated to be more than 15 GW by 2050, equivalent to some 230–300 LDR-50 reactors across approximately 150–200 suitable networks.

District heating market
District heating is estimated to account for approximately 13 per cent of the heat supplied to buildings in the EU1. Although European district heating systems have historically relied heavily on fossil fuels, the share of renewable energy and waste heat in the fuel mix has increased in recent years2. Research scenarios, including the Heat Roadmap Europe study, have estimated that in the studied EU countries, over 50 per cent of total heat demand could be cost-efficiently provided through district heating by 20503.
For district heating, Steady Energy focuses on offering complete modular nuclear heating solutions for urban district heating networks primarily in the priority markets and elsewhere in Europe.
Potential growth markets
Steady Energy has identified district cooling as a potential growth market. Global demand for spatial cooling is increasing at a faster rate than demand for heating and in urban areas, district cooling networks offer a high-performance alternative to traditional air-conditioning units. In the view of Steady Energy’s Management, district cooling is a competitive solution at scale, enabling large complexes to be cooled cost-effectively.
Steady Energy has also identified industrial heat as an additional target application of the LDR-50 technology, with the reactor suited to processes requiring low to moderate temperature heat, including food processing, pharmaceutical, paper and pulp, and textile industries.
Further, Steady Energy has identified seawater desalination as an additional target application of the LDR-50 technology, leveraging the reactor’s ability to produce large volumes of process heat for thermal desalination methods.
Leading company in the heat-only SMR market
The competitive landscape for nuclear heat production can be assessed across two principal categories: small modular reactor (SMR) heat-only technologies, which compete directly with the LDR-50, and small modular reactor Combined Heat and Power (SMR CHP) technologies, which produce electricity as the primary output and may offer heat as a by-product.
In Steady Energy Management’s view, Steady Energy is a leading company in the heat-only SMR market.
Multiple companies are developing SMR CHP technologies primarily targeting electricity production. SMR CHP concepts are designed at a significantly larger scale compared to the LDR-50 and carry materially higher acquisition costs for the client: estimated cost of a SMR CHP plant start from approximately EUR 3 billion, significantly higher than the acquisition cost of a serial-manufactured LDR-50 reactor, which limits utilities’ ability to invest in such systems without government or other public support.
