The Plymouth Township Planning Commission unanimously approved the final site plan for Delta Electronics' battery storage expansion on October 14. The project adds a 12,500-square-foot microgrid installation along with additional battery storage equipment, a transformer, and a natural gas generator.
Why it matters
The expansion builds on an existing microgrid at the facility and serves as a demonstration site for energy technologies that businesses could later install elsewhere. The project is not itself a data center, though it adds power infrastructure to the Plymouth Township area.
The expansion adds roughly 10 megawatt-hours of battery storage and 5 megawatts of power capacity on a 4.98-acre property at 47659 Halyard Drive. Delta did not disclose the investment cost, job creation figures, or a firm construction schedule.
The players
Delta Electronics
A global power electronics and energy management company whose Plymouth Township facility is hosting the microgrid and battery storage expansion.
DTE Energy
A Detroit-based utility that partnered with Delta Electronics on the facility's existing microgrid system.
The details
Commissioners approved the project with conditions including vibration documentation, updated landscaping information, lighting adjustments, and irrigation for screening plants. The plan would remove 23 trees, including one heritage tree, and replace them with 40 new trees along with 44 arborvitae.
Timeline
May: a DBusiness report said the existing microgrid cut the facility's grid electricity reliance by about 50% annually.
Earlier in 2026: Delta Electronics unveiled its existing microgrid in partnership with DTE Energy.
October 14, 2026: The Plymouth Township Planning Commission unanimously approved the final site plan.
End of 2026: Delta hopes to begin concrete work.
Spring 2027: Delivery of new battery equipment could be delayed until this period.
The Tech Race
The expansion extends Delta's existing microgrid at Metro West Technology Park by adding battery storage and generation capacity to the same system. It positions the facility as a showcase for energy technology Delta hopes to sell to other businesses.
Residents near Halyard Drive may see construction activity and additional lighting, screening, and tree removal once work begins. The project's added generation and storage capacity could shape how the local grid serves area businesses over time.
The takeaway
Energy storage paired with on-site generation is becoming a practical way for businesses to reduce grid dependence. Watch for how Delta's demonstration site performs as it shapes decisions for other companies.
