Hebei Shopping Mall BESS — 1.6 MW / 3.34 MWh Commercial-Industrial Battery Storage

The mall sits in central Hebei Province, in the Beijing-Tianjin-Hebei industrial belt where retail real-estate operators have leaned on grid power plus standard utility connections for decades. By 2024 two things had changed for operators in this region. Hebei provincial commercial tariffs moved toward time-of-use structures, with demand-charge components climbing faster than energy charges — the largest line item on the operator’s electricity bill wasn’t kWh consumption, it was the mall’s late-afternoon-to-evening peak driven by simultaneous HVAC re-cooling cycles, escalator load on weekend traffic, and tenant cooking-equipment ramps. These weren’t theoretical events. The operator paid for them every month. At the same time, the mall’s planning team had committed to installing a DC fast-charger array — 200 kW class, multi-stall — to capture EV-driver footfall as Hebei’s EV penetration accelerated. The existing grid connection couldn’t absorb that buffered load without a costly transformer upgrade and a connection-fee re-tariff that would have erased the EV-charging revenue case for several years.

Standard mall electrical upgrades in 2024 were sized for either demand-charge reduction or EV charging buffering — rarely both, and almost never with a single shared asset. This project couldn’t be solved with a single-application design. The operator needed a system that could shave the 4-hour evening peak window across the mall’s general loads, absorb the bursty 200 kW DC fast-charger demand pulses without re-imposing those pulses on the grid connection, and provide power-quality reserve so that simultaneous tenant ramp events wouldn’t trigger voltage excursions on shared circuits. Tender evaluation landed on 3.34 MWh of energy capacity at 1.6 MW BESS rated power, 2-hour discharge, with grid-following operation tied behind-the-meter at the mall’s primary switchgear (final MV-side or LV-side interconnection determined at detailed design). Henley Power’s HLY-BESS-Commercial-Industrial-418kWh platform fit cleanly: 8 containerized blocks in parallel, each with an integrated 200 kW PCS in Mode A configuration, eliminating the separate central-PCS procurement and commissioning step that would have added 8–12 weeks to the schedule and a second supplier signature to the warranty chain. One product, one warranty, one phone number to call. TU Delft research has documented that BESS-buffered fast-charging stations can reduce grid connection size by up to 80%. That’s the architectural pattern this project executes at C&I scale.

What got Henley Power selected over the other shortlisted integrator wasn’t price alone. The mall operator’s group treasury team needed documentation depth: IEC test reports under NDA, multi-supplier cell homologation records, parent-warranty mechanics, and FSR documentation aligned to the operator’s group-level financing covenants. Henley Power’s contracting position is direct manufacturer-to-buyer: one signatory, one warranty chain, one accountability path. Cell sourcing is multi-supplier homologated LFP from publicly listed Tier-1 cell manufacturers — specific suppliers documented under NDA in the project bankability dossier, never on public pages. The system has been operating since commissioning in 2025. It’s been collecting cycle field data against design assumptions for a Q3 2026 24-month performance disclosure window. That’s the milestone that converts the design case into measured-outcome proof for the next wave of European mall and CPO buyers. To be direct: a competitor on that shortlist carried deeper public bankability credentials and longer accumulated BESS operating history — the mall operator’s group treasury ultimately weighted documented multi-supplier cell homologation and a clear warranty chain over balance-sheet brand premium.
