Warsaw-based Synthos Green Energy and Bulgarian firm Blue Bird Energy agreed to cooperate in the installation of small modular reactors.

Synthos Green Energy (SGE) and Blue Bird Energy (BBE) have signed a letter of intent (LOI) to partner on the deployment of small modular reactors in Bulgaria, SGE said.

The two firms plan to establish a joint venture aimed at building a fleet of up to six BWRX-300 SMRs in Bulgaria.

The project will bring Bulgaria zero-emission, affordable baseload electricity to the power industry, support AI and other data centers, and decarbonize district heating. according to the update.

SGE: The BWRX-300 is the most commercially advanced SMR in the market today

SGE claims that the BWRX-300, designed by US company GE Vernova Hitachi Nuclear Energy, is the most commercially advanced SMR in the market today.

A 300 MW facility is currently under construction in Ontario, Canada, the Polish company added and pointed to GE Vernova Hitachi’s 65 years of experience “developing proven nuclear technology.”

The new joint venture in Bulgaria will select and prepare deployment sites, facilitate site and design licensing, manage construction and project development and coordinate project funding.

SGE CEO Rafał Kasprów said partnering with BBE would strengthen his company’s European SMR development platform and help deliver affordable energy that meets the needs of the Bulgarian people.

Kasprów: Bulgaria joins the US, Canada, Poland, Hungary, and others who are in the process of deploying US technology

“With today’s announcement, Bulgaria joins the US, Canada, Poland, Hungary, and others who are in the process of deploying this world-leading US technology,” he added.

Of note, in September, Bulgaria’s Minister of Energy Zhecho Stankov said the country should discuss the possibility of installing SMRs on its territory with companies developing the technology.

According to Kalin Peshov, Chairman of the Board of Directors of Blue Bird Energy, the company is excited to partner with energy frontrunners such as GE Vernova Hitachi (GVH) and SGE.

The 65 years of nuclear experience of GVH and the proven track record of SGE bringing the BWRX-300 technology to Europe would be invaluable in supporting the company’s mission to provide Bulgaria with a secured long-term energy supply, he explained.

Young companies

BBE and SGE were established to secure the deployment of an SMR fleet in Bulgaria, Poland, and Europe, according to their websites.

The main shareholders of BBE are construction firm Glavbolgarstroy Holding (GBS) and copper mining and processing company Asarel-Medet JSC. It was founded four years ago.
