Envision Energy Shows 4 MWh Storage
Envision Energy launches 4 MWh storage block
Envision Energy unveiled a fully integrated 4 MWh energy‑storage block at The smarter E 2026, promising long‑duration power for grid‑forming applications. The block comes with its own string‑level power conversion system, fire‑suppression gear and auxiliary transformer, making it a plug‑and‑play solution for utilities and large‑scale renewables.
Solid‑State Transformer and 800 V DC battery target AI data centres
For AI‑heavy data centres, Envision displayed a solid‑state transformer (SST) paired with an 800 V DC battery that can be built with either lithium‑iron‑phosphate (LFP) or sodium‑ion chemistry. According to BESS CTO Dr. Kotub Uddin, the high‑voltage DC format cuts conversion losses and enables tighter integration with AI workloads that demand stable, high‑density power.
Hybrid and grid‑forming solutions expand across Europe
Envision’s European head of BESS, Daniel Greten, said the company is deepening its footprint in core markets such as Germany, Spain and the UK while moving into Eastern Europe (Poland, Romania) and the Nordics, with Finland as the first target. The firm is bundling its storage blocks with AI‑driven control software to create hybrid systems that can both store energy and provide grid‑forming services, a capability increasingly required as Europe pushes for higher renewable shares.
What it means for Israel
Israel’s solar market is already seeing rapid rooftop growth, but storage remains a bottleneck for achieving higher renewable penetration. A 4 MWh block represents a substantial amount of stored energy that could help convert surplus solar generation into valuable grid‑balancing capacity. Such large‑scale, turnkey storage solutions can support Israel’s goal of reaching a 30 % renewable electricity share by 2030.

FAQ
What is the capacity of Envision’s new storage block?
The block stores 4 MWh of electricity and includes its own power conversion, fire‑suppression and auxiliary transformer.
Which battery chemistries are offered for the 800 V DC battery?
Customers can choose between lithium‑iron‑phosphate (LFP) and sodium‑ion cells.
Why is a solid‑state transformer important for AI data centres?
It reduces conversion losses and provides a stable, high‑density power supply that matches AI workloads’ strict reliability needs.
Which European markets is Envision expanding into?
Beyond Germany, Spain and the UK, Envision is targeting Poland, Romania and the Nordic region, starting with Finland.
How could the 4 MWh block benefit Israeli solar owners?
It can store enough energy to cover about 23 % of a typical 10 kWp home system’s annual output, turning excess solar into valuable grid‑balancing power.
What does ‘grid‑forming’ mean in this context?
Grid‑forming storage can set voltage and frequency, effectively acting like a virtual power plant that stabilises the grid when renewable output fluctuates.
