Toki Power Holding GmbH (Toki Power), the electricity trading part of Renalfa Solarpro Group (Renalfa Group), closed a major transaction in Romania – the acquisition of a 150 MW standalone Battery Energy Storage System (BESS) project.
The deal was finalised on December 5, 2025, and is a milestone for the company’s accelerated development in Southeastern Europe’s rapidly evolving energy landscape.
The newly acquired 150 MW standalone BESS project is designed to provide fast-response flexibility and grid support services, helping to integrate more renewable energy into the Romanian electricity system.
It follows the pioneer strategy of hybridising the trader Toki’s market position with direct investment in own flexible assets, which brings superior operational capabilities. The company has already invested in a 110 MW distributed portfolio of 4h standalone BESS in Bulgaria, whose first few projects started operating in October 2025.
The Romanian project has 2h duration, extendable to 4h, and will become operational by Q4’2026, further strengthening Toki Power’s role as a key player in the regions’s transition to a resilient, secure, and decarbonised energy sector.
This acquisition directly supports Toki Power’s strategic mission to deliver higher-value energy solutions to its clients in Romania. Through the integration of a large-scale storage asset into its portfolio, Toki Power will be able to offer new generation of electricity services:
– Improved supply side integration and optimization of renewable generation assets, enabling producers to maximise captured market value;
– Greater resilience and reliability, supporting clients who require dispatchable power profiles amid increasing grid constraints;
– Advanced digital optimisation, leveraging Toki Power’s platforms to deliver real-time scheduling, forecasting, and automated market participation;
– Enhanced balancing and flexibility services, ensuring lower cost and predictable energy supply for customers facing volatility on the day-ahead and intra-day markets;
– Demand side peak-shaving and load-management solutions, reducing operational costs for energy-intensive industrial customers.
