The project intends to deliver zero-emission, affordable, baseload electricity to power industry in Bulgaria, support AI and other data centres, and decarbonise district heating, SGE said in a press release in late December.
The joint venture will choose and prepare SMR deployment sites, facilitate site and design licensing, manage construction and project development, arrange funding and guarantee safe, reliable, and efficient commercial operation.
The BWRX-300 reactors are designed by U.S.-based reactor manufacturer GE Vernova Hitachi (GVH). With passive safety systems, modular construction, and projected capital cost reductions of up to 60% per MW, the BWRX-300 is projected to be the most competitive and quickest-to-market SMR, per the press release.
"With today’s announcement, Bulgaria joins the U.S., Canada, Poland, Hungary, and others who are in the process of deploying this world leading U.S. technology," SGE CEO Rafal Kasprow said. "We are confident that the Bulgarian economy will benefit from low-cost, reliable, baseload energy. Additionally, Bulgarian companies will play a significant role in the global BWRX-300 supply chain."
SGE, founded in 2019, is a co-investor in the standard design for the BWRX-300, according to company information. Currently, SGE is establishing partnerships and projects in more than a half-dozen European countries.
Sofia-based Blue Bird Energy specialises in conducting preliminary and pre-investment studies, site selection, design, construction and commissioning of investment projects for small modular nuclear power reactors in Bulgaria, per the national commercial register. Its main shareholders are construction and engineering group Glavbolgarstroy and Bulgaria’s biggest copper mining and processing company Assarel-Medet.
