The Maritsa East 2 power plant, Bulgaria’s largest coal-based facility, is set to embark on a significant transition by incorporating biomass into its fuel mix. This initiative, which will commence at the end of February, seeks to integrate wood materials with lignite, representing a strategic move towards diversifying energy sources and enhancing sustainability.
Initially, the pilot program will see biomass comprise approximately 5% of the total fuel blend. Should the outcomes—both technical and economic—prove favorable, there is potential for this percentage to rise to as high as 30%. This increase could lead to a reduction in generation costs by up to 50 euros per megawatt-hour (MWh), thereby improving the plant’s competitive position within the energy market.
The anticipated decrease in production costs is expected not only to bolster competitiveness but also to promote increased utilization of locally sourced lignite. By streamlining the overall cost structure, management aims to secure the long-term operational viability of the Maritsa East energy complex, which plays a crucial role in Bulgaria’s energy landscape.
Energy Minister Zhecho Stankov has indicated that currently five generating units are operational at Maritsa East 2. With the integration of biomass planned, authorities aim for all eight units to be fully operational within a year, contingent on a smooth transition process.
To facilitate this shift towards biomass utilization, the plant will need to invest in specialized equipment designed for handling and processing these new materials. Funding avenues include support from the Just Transition Fund, which has allocated 88 million euros specifically for regions reliant on coal, along with possibilities for loan financing.
