Germany gains a boost in the energy sector with a new 135 MWh battery from Jinko ESS, combining advanced technology and high efficiency to power solar plants.
The European energy transition gains a significant chapter with the integration of a robust 135 MWh storage system on German soil. The project, led by Jinko ESS—the specialized storage arm of the Chinese giant JinkoSolar—was officially announced in October 2026 and promises to transform the electricity supply dynamics in the region.
This cutting‑edge infrastructure was directly coupled to a photovoltaic plant, operating under the hybrid PPA contract model. This innovative format consolidates solar generation, strategic storage, and commercial delivery into a single agreement, ensuring greater predictability and stability for the grid and end consumers.
Proven technological innovation and efficiency
The project uses the Jinko Tera line, a liquid‑cooled battery system that stands out in the market for its high performance. Each module delivers 5.01 MWh of capacity, boasting a 94.1% conversion rate verified in rigorous laboratory tests. This rate ensures minimal electricity loss during charge and discharge cycles.
One of the major engineering differentiators of this installation is the architectural layout of the cabinets, structured in a mirrored format with type A and type B units. This configuration optimizes physical space and delivers significant operational gains for the deployment.
Roberto Murgioni, general manager of Jinko ESS in Europe, highlighted:
We are very pleased to continue strengthening our cooperation in Germany with this 135 MWh project, combining solar energy and storage to make the renewable mix more flexible and reliable.
Thanks to this intelligent structural design, the company was able to reduce the area required for equipment installation by 17.7%. Additionally, the arrangement cut the use of DC cables in half, dramatically speeding up assembly and connection to the distribution network.
Expansion and the Future of the Energy Market
The initiative in Germany consolidates a series of recent investments by the brand on the European continent, keeping pace with the rapid expansion of clean energy sources in the region. The company distinguishes this application as a “green battery,” meaning a storage capacity directly connected to renewable generation, unlike solutions aimed purely at broad market stabilization.
With the growing need to flexibly supply power amid solar intermittency, hybrid projects of this magnitude become indispensable. Jinko ESS signals that it will continue to forge strategic partnerships in Europe, expanding its technological portfolio and paving the way for a more sustainable and resilient energy future.
