Bulgaria’s largest coal-fired power facility, Maritsa East 2, is set to embark on a significant transformation by incorporating biomass into its fuel mix. This initiative aims to diversify energy sources and reduce operational costs, with the pilot program scheduled to commence at the end of February. The integration of wood materials alongside lignite marks a pivotal shift in the plant’s operational strategy.
Initially, biomass will constitute approximately 5% of the fuel blend during the pilot phase. Should the technical and economic evaluations yield favorable results, this percentage could escalate to as much as 30%. Plant officials project that such an increase could lead to a reduction in generation costs by up to 50 euros per megawatt-hour (MWh), thereby enhancing the facility’s competitive standing in the market.
The anticipated decrease in production costs is expected to not only improve competitiveness but also promote increased utilization of locally sourced lignite. By optimizing the overall cost structure, management aims to fortify the long-term sustainability of the Maritsa East energy complex, which plays a crucial role in Bulgaria’s energy landscape.
According to Energy Minister Zhecho Stankov, five generating units are currently operational at Maritsa East 2. With the planned introduction of biomass, authorities aim for all eight units to be fully operational within a year, contingent on a smooth transition process.
To facilitate this transition, the plant will require specialized equipment designed for handling and processing biomass. Funding avenues include support from the Just Transition Fund, which has allocated 88 million euros for regions reliant on coal, along with potential loan financing options.
