(Sofia / Ontario – December 2, 2025) — Today, a consortium composed of Laurentis Energy Partners (Laurentis), its subsidiary Canadian Nuclear Partners S.A. (CNPSA), and BWX Technologies (BWXT) signed an Owner’s Engineer contract with Kozloduy NPP-New Build EAD. The agreement covers the planned construction of two new Westinghouse AP1000 reactor units (Units 7 and 8) at Bulgaria’s Kozloduy Nuclear Power Plant. The contract is valued at hundreds of millions of euros and spans up to ten years.

Under the agreement, the consortium will deliver specialized technical advisory and project-management oversight throughout all major phases of the project — from front-end engineering and constructability reviews, through design management and procurement oversight, to construction supervision, commissioning, and readiness for operation. The initial phase, lasting about 12 months, aims to prepare for a potential Final Investment Decision (FID); if approved, the consortium will remain involved through the full execution of the build.

The two new units are planned to have a combined installed capacity of approximately 2,300 MWe. Unit 7 is targeted to come online in 2035, followed by Unit 8 in 2037. Once operational, the AP1000 reactors will significantly enhance Bulgaria’s clean-energy capacity, bolstering its energy security and supporting the country’s long-term low-carbon transition.

Bulgaria’s Minister of Energy Zhecho Stankov described the signing as “one of the most important contracts after the EPC agreement,” marking a decisive step forward in the implementation of the Kozloduy expansion project. He stressed that the project will not only boost national power generation capacity, but also provide opportunities for domestic industry and technical workforce development.

From Canada’s perspective, Ontario’s Minister of Energy and Mines Stephen Lecce emphasized that the partnership underscores Canada’s leadership in clean, emissions-free nuclear energy. By exporting Ontario’s nuclear expertise, Canada supports Bulgaria’s large-scale nuclear expansion and deepens international cooperation in the nuclear sector.

Leaders of the consortium also expressed confidence in the project’s success. Laurentis President and CEO Leslie McWilliams noted that although their background has been in CANDU technology, their project-management and Owner’s Engineer competencies are fully transferable to AP1000 and other advanced reactor types. Representatives from BWXT and CNPSA similarly highlighted decades of experience delivering large-scale nuclear projects worldwide, ensuring that the Kozloduy New Build will be executed safely, on time and within budget.

This agreement marks a milestone not only for Bulgaria’s energy future, but also for Canada’s role in global clean-energy development. As the project advances, the new Kozloduy units may become a cornerstone of sustainable and secure power supply in Southeastern Europe.
