Most of the 400 MWh battery energy storage portfolio announced by Jinko ESS and Taliva Energy for Eastern Europe is allocated to projects in Romania, Taliva Energy told Energynomics. The agreement covers 19 utility-scale BESS projects, with Romania confirmed as one of the key markets within the portfolio, although the companies are not yet disclosing the exact Romanian capacity, the number of local projects or their locations.
In the original announcement, Jinko ESS and Taliva Energy said they had signed contracts covering 400 MWh of battery energy storage system projects across multiple utility-scale developments in Eastern Europe. Taliva Energy was described as a clean energy company focused on full-scope energy storage solutions and large-scale energy infrastructure in Romania and Türkiye, with a growing presence across Europe.
In written answers to Energynomics, Taliva Energy confirmed the Romanian relevance of the portfolio. “Romania is one of the key focus markets within the scope of this agreement,” the company said. The projects are at different development stages, including development, grid connection-related processes, permitting, technical planning and preparation for implementation.
The company did not disclose counties, localities or project areas, citing the current stage of the portfolio. It also did not provide a country-level precise split between Romania and Türkiye.
Taliva Energy acts as integrated project partner
Taliva Energy’s role goes beyond a simple commercial interface or equipment-procurement position. The company told Energynomics it acts as “a full-scope energy storage solutions provider and integrated project partner”. Its scope includes technology and product selection, procurement, system integration, project management, service capabilities and energy management system integration through PowerKonnekt EMS.
The exact contractual role may differ from project to project, depending on the structure of each development. Still, the company positions itself as the integrated partner connecting technology, local market experience, implementation capability and long-term operational know-how.
All projects covered by the agreement are utility-scale energy storage applications. Taliva Energy said their use cases include renewable energy integration, grid flexibility, grid stability and support for the evolving needs of the electricity market. Project-specific commercial details – including potential participation in ancillary services, energy arbitrage, balancing markets, hybrid project structures or other revenue models – are not being disclosed at this stage.
The current implementation plan is ambitious. Taliva Energy said it aims to finalise all projects covered by the agreement during 2026. For Romania, the practical questions now concern grid-connection status, permitting progress, delivery schedule, project ownership, operating model and the future role of these batteries in balancing, flexibility and renewable-energy integration.
For the Romanian BESS market, the Jinko ESS-Taliva Energy agreement adds another sign that storage is moving from isolated announcements to multi-project portfolios.
