Envision Energy announced Nov. 9 that it plans a 442-megawatt-hour battery storage project with ju:niz Energy in Vöhringen, Bavaria, adding capacity intended to help Germany balance power as renewable generation expands.
The project, called Smareg 13 or Vöhringen II, would be next to the operating Smareg 12 facility. Envision says its Gen 8 system is designed to store electricity for four hours, operate in grid-forming mode and run with low noise. The company says storage can help balance power as Germany integrates more renewable energy. Its announcement states the system’s energy capacity but gives no power rating in megawatts.
Envision’s announcement assigns ju:niz responsibility for developing and financing the project, overseeing implementation and managing long-term operations. Envision will supply the battery technology and support project delivery. ju:niz Energy Chief Operating Officer Vural Oezcan called the project “an important contribution to flexibility and system stability.”
The partners describe Smareg 13 as their third project together. Envision says it would bring their collaboration to nearly 600 MWh, although the two earlier projects had not completed delivery when the partners advanced this one. Those projects are S10 in Baindt, at 88.4 MWh, and S15 in Schöningen, at 52.2 MWh. ju:niz announced them in July with a combined capacity of 140.6 MWh.
BESS Check’s listing, based on Germany’s Market Master Data Register (MaStR), shows SMAREG 13 at 100 MW and 401 MWh, with March 2028 as its planned date. That capacity is 41 MWh below Envision’s announcement; the two sources give no reason for the difference. BESS Check says a registry entry alone does not establish that a project has a permit, has begun construction or will operate. Envision’s announcement gives no construction-start or commissioning date.
