Changing Renewable Energy in Estonia

Trinasolar is making significant strides in the renewable energy sector with its latest partnership with Estonian energy company Sunly. This initiative not only enhances the operational flexibility of the solar park but also contributes to the broader goals of sustainability and grid stability in Estonia.

Details of the BESS Deployment

The BESS, to be delivered in late 2025, will utilize Trinasolar's advanced Elementa 2 platform. This system features:

  • 12 battery cabinets
  • Six 4.4 MVA Power Conversion System (PCS) units
  • A Power Plant Controller

The integration of this storage solution will significantly enhance the reliability of energy supply, allowing for improved management of renewable energy sources.

Strategic Importance for the Baltic Region

As Estonia accelerates its transition to renewable energy, the Raba Solar Park project embodies the country’s commitment to integrating higher shares of renewables into its energy mix. By adding storage capabilities, Sunly aims to address the challenges associated with intermittent energy generation, thereby stabilizing the grid and supporting the country's clean energy objectives. This project also aligns with the European Union's targets for renewable energy adoption and sustainability.

Trinasolar's Commitment to Innovation

Gonzalo de la Viña, President of Trinasolar Europe and Latin America, emphasized the significance of this partnership, stating that it not only showcases Trinasolar’s comprehensive capabilities in delivering integrated energy solutions but also strengthens their commitment to supporting the Baltic region's clean energy transition. The inclusion of a 16-year Long-Term Service Agreement guarantees ongoing maintenance and performance, ensuring that the system operates efficiently ovstainable Future
