en.Wedoany.com Reported - On July 15, Trina Storage signed an agreement with renewable energy developer OX2 to provide an integrated battery energy storage solution for the latter's Fageråsen energy storage project in Sweden. This collaboration not only solidifies the long-term strategic partnership between the two parties in the Nordic energy storage market, but also marks the first deployment in Europe of Trina Storage's latest AC-DC integrated solution—the Elementa + Electra 13.8MVA/50MWh.
The Fageråsen project has an installed capacity of 50MW/209MWh, utilizing Trina Storage's Elementa Diamond 3 DC energy storage system combined with the newly released Electra 13.8 AC unit platform. This combination streamlines the architecture from battery to grid, enhancing overall system efficiency.
This agreement marks the third large-scale battery energy storage order awarded to Trina Storage by OX2, following the Kannisto and Korkeamaa projects in Finland. The cumulative storage capacity of the three projects totals approximately 680MWh, fully demonstrating the depth and mutual trust of the collaboration, as well as a shared commitment to the Nordic energy transition. Located near the Fageråsen wind farm in Malung-Sälen, the project will effectively enhance local grid flexibility upon completion, facilitating a higher proportion of renewable energy integration into the Swedish power system.
Under the agreement, Trina Storage will provide the Elementa + Electra 13.8MVA/50MWh AC-DC integrated energy storage solution, along with a plant power controller (PPC), commissioning services, and a long-term operation and maintenance service agreement. Equipment delivery is scheduled to commence in the first quarter of 2027, ensuring OX2 achieves grid connection and commercial operation of the project by the end of 2027.
The Elementa Diamond 3 single-unit capacity has been increased to 6.25MWh, equipped with a self-developed 587Ah large-format battery cell and an intelligent liquid cooling temperature control system, integrating energy density enhancement and full lifecycle thermal management into a unified platform design. Its temperature control, safety, anti-corrosion, fire protection, and enclosure protection are fully integrated, supplemented by pre-validation under extreme conditions in a self-built 478m³ ultra-large environmental testing chamber, ensuring high reliability and replicability of the product under complex global climate and grid conditions. The Electra AC integrated unit deeply integrates PCS, medium-voltage step-up, secondary control, and communication acquisition, enabling factory-end whole-unit commissioning, significantly reducing on-site commissioning time and multi-vendor coordination costs, upgrading the AC side from a decentralized supporting unit to a system-level grid-connected control hub. The synergy between the two ensures that the energy storage system not only "stores well" but also "connects, dispatches, and operates stably"—this is the core support for Trina Storage to unlock full-stack capabilities from the DC side to the AC side and solve global grid connection challenges with a platform-based solution.
Gabriele Buccini, Head of Trina Storage's European business, stated that OX2's renewed selection of Trina Storage is a strong recognition of the collaboration results over the past year. The Fageråsen project not only deepens the partnership between the two parties but also serves as a key strategic deployment project for Trina Storage's integrated solution in the European market. These practices demonstrate that deep strategic cooperation and leading system integration capabilities can accelerate the large-scale deployment of large-scale energy storage projects in Europe.
The energy storage station is expected to begin construction in the summer of 2026 and commence commercial operation in mid-2027. Upon completion, it will be owned and operated by OX2, incorporated into its continuously expanding renewable energy asset portfolio in Sweden. This agreement further expands Trina Storage's market presence in the Nordic region and solidifies its industry position as a trusted partner in the large-scale battery energy storage sector in Europe.
