Laurentis Energy Partners takes key role in delivering nuclear generation in Bulgaria

Significant owner's engineer contract to span up to 10 years

SOFIA, Bulgaria, Dec. 2, 2025 /CNW/ - Laurentis Energy Partners (Laurentis), together with its subsidiary Canadian Nuclear Partners S.A. (CNPSA) and BWXT Canada Ltd. (BWXT), have signed a contract as a three-party consortium to advance two new Westinghouse AP1000 reactor units (Units 7 and 8) at Bulgaria's Kozloduy Nuclear Power Plant New Build.

The owner's engineer contract is valued at hundreds of millions of euros and spans up to ten years, providing sustained engineering and project oversight through all major phases of the program.

Announced today in Sofia, the partnership was formalized at an event attended by Ontario's Minister of Energy and Mines, Stephen Lecce, Bulgaria's Minister of Energy, Zhecho Stankov, and senior representatives of the consortium.

The consortium will provide specialized technical advisory services and project-management oversight across all stages of the Kozloduy New Build Project to help ensure alignment with project objectives, regulatory requirements, safety expectations, and delivery strategy.

The work is structured into two phases: Phase 1 focuses on pre-Final Investment Decision (FID) activities, including front-end engineering, constructability reviews, early project planning, and preparation for Engineering, Procurement, and Construction negotiations. Pending the Bulgarian government's decision to proceed, Phase 2 extends the consortium's support through design, construction, and commissioning.

With a combined capacity of 2,300 MWe, Bulgaria expects the first new Westinghouse AP1000 unit at Kozloduy – Unit 7 – will be operational in 2035, followed by Unit 8 in 2037. Once complete, the new units will significantly reinforce Bulgaria's energy security and support its long-term low-carbon transition.
