System integrator Wärtsilä has launched a 5MWh, 20-foot container battery energy storage system (BESS) product.
The firm said its latest grid-scale solution, the Quantum3, has new safety, cybersecurity, energy density, and sustainability design features in a 20-foot ISO container form factor.

It is an AC block solution, meaning string-based power conversion systems (PCS) are integrated, enhancing the availability, efficiency, and reliability of the system, it claimed. The BESS is designed to achieve an optimal balance between energy density and weight, the company added.
Wärtsilä’s announcement did not reveal the energy storage capacity of the product, but a company spokesperson told Energy-Storage.news it is 5MWh. That is in line with most other grid-scale BESS solutions, including one launched last month by Canada-based EVLO.
The company’s comment about balancing energy density and weight comes in light of concerns about the very most energy-dense 20-foot products potentially being too heavy for some roads and adding to shipping costs, expressed by Wärtsilä VP energy storage & optimisation Andy Tang in an interview in June (Premium access).
Referring to the Quantum3’s features, Tang commented in the announcement: “These are features we have worked extremely hard on and are very proud of. We have a proven track record of safe and reliable delivery worldwide. Quantum3 will help to further strengthen confidence among customers, local communities, and first responders that Wärtsilä’s systems will stand the test of time.”
The firm’s previous product, the Quantum2, packed 4MWh per 20-foot unit.
Its grid-scale BESS products can also be deployed in combination with its energy management system (EMS) platform, the GEMS Digital Energy Platform, which an executive discussed in a recent interview (Premium access).
