ContourGlobal previously held a majority stake in the Maritsa East 3 lignite-fired thermal power plant (808 MW), which historically contributed to Bulgaria’s energy security.
Following the expiry of the long-term PPA in 2024, operations were significantly reduced, with the plant running only intermittently for system support. Repurposing options were explored while maintaining availability for security of supply, with two units placed in reserve and the others used only during peak demand.
In 2026, ContourGlobal has entered into a definitive agreement for the sale of its 73% equity interest in Maritsa East 3 to one of Bulgaria’s leading electricity traders and energy market participants, in line with the company’s strategy to accelerate its transition towards cleaner sources of generation.
Today, it retains 73% ownership and operational control of Maritsa BESS 1, together with temporary rights to use existing grid connection infrastructure within the site to support its operation.
Furthermore, the Maritsa East area remains a key location for the company’s future growth. With a development pipeline of close to 700 MW of renewable generation and energy storage, ContourGlobal is contributing to the transformation of the region into a modern energy hub.
