Yongfeng Industrial Base, Xibeiwang Town, Haidian District, Beijing — Diesel Generator Project

• Fragmented fleet: 23 standalone generators across the base, sourced from 9 different vendors over a decade. Brands, capacities, and fuel grades were inconsistent, making centralized maintenance nearly impossible.
• Cold-start failures: During Beijing's winter cold snaps, 6 units failed to start due to frozen fuel lines and weakened batteries. One incident left a biotech cold-storage lab without power for 40 minutes, risking ¥2M in biological samples.
• Slow manual switching: Most units lacked ATS; security patrols had to manually start generators, taking 4–8 minutes — far too long for data center UPS ride-through windows.
• Emission & noise constraints: Open units exceeded Beijing's Class-1 environmental noise limit (≤55 dB nighttime) and failed to meet the new GB 20891-2022 emission standard, triggering district EPA warnings.
• Zero visibility: No remote monitoring — property managers drove between buildings for daily inspections, and several units ran out of fuel unnoticed during extended outages.

• ✓Fleet standardization: Unified brand, model, and tiered capacities (200 / 400 / 800 kVA) across all base buildings.
• ✓Cold-climate reliability: Guaranteed start at -20°C within 10 seconds, with battery warmers and fuel-line heaters as standard.
• ✓Fast auto-transfer: ATS integration achieving <8s transfer for data center and lab-critical loads.
• ✓Beijing environmental compliance: Silent canopy ≤70 dB(A) at 7m + Stage-V emission after-treatment (DOC+DPF+SCR).
• ✓Unified IoT platform: One cloud dashboard for the entire base fleet, with auto-alerts and monthly O&M reports.

• Pre-qualification: 16 suppliers applied; 6 passed based on OEM authorization, Beijing municipal emission certification, and ≥3 data-center / lab projects in the capital region.
• Technical evaluation: Bidders submitted emission test reports, acoustic designs, cold-start schemes, and 5-year TCO models. We were the only bidder to include a -20°C cold-start validation protocol.
• On-site demonstration: Shortlisted vendors deployed units to Building B7 (data center) and Building C3 (biotech lab) for live cold-start and auto-transfer drills. Our units achieved 6.4s transfer — the fastest on record.
• Commercial bid: Evaluated within a framework budget of ¥8.6M. We won with the best comprehensive score (technical 44/45 + commercial 38/40 + demo 10/10).
• Award: Master framework signed for 23 units (tiered 200/400/800 kVA) + a centralized IoT monitoring platform + 5-year full-service SLA.

• ✓Zero critical-load interruption: Guarantee seamless backup for data centers, biotech labs, and HQ offices through Beijing's winter peaks.
• ✓Unified, visible fleet: One platform to monitor all 23 units' status, fuel, battery, and maintenance schedule.
• ✓Audit-ready compliance: Emission and noise reports on file for Beijing EPA and Haidian District inspections.
• ✓Scalable template: A standardized deployment blueprint reusable for future base expansions.

We delivered an integrated "Cold-Climate Silent Fleet + Smart ATS + Centralized IoT Platform + Lifecycle Service" solution:

• Phase 1 — Master planning: Produced a base-wide deployment map, prioritizing the data center (B7) and biotech lab (C3) for first-phase installation.
• Phase 2 — Civil & plinth works: Poured 23 vibration-isolated reinforced plinths with cable conduits and earthing grids, coordinated with the base's weekend maintenance windows to avoid tenant disruption.
• Phase 3 — Delivery & placement: Units delivered in three batches and positioned with mobile cranes during low-occupancy periods; cold-climate packages pre-installed at the factory.
• Phase 4 — ATS & commissioning: Installed ATS panels and ran interconnection cables; each unit underwent a -20°C simulated cold-start and full-load endurance run. All 23 achieved <8s transfer.
• Phase 5 — IoT platform rollout: Onboarded all units to the centralized dashboard; property managers trained on alert configuration and monthly report export.
• Phase 6 — Training & handover: Two-day hands-on workshop for the base O&M team covering cold-start override, daily checks, and emergency procedures; delivered a complete digital O&M manual.

After one full winter season and 14 months of operation, the project delivered outstanding results:

• ✓Winter resilience proven: During Beijing's January cold snap (-18°C), all 23 units auto-started within 8 seconds — zero failures, zero cold-storage or data loss.
• ✓Faster than specification: Average 6.4s transfer beat the 8s tender requirement by 20%.
• ✓Full environmental compliance: Post-installation tests at 68 dB and Stage-V emissions passed Beijing EPA audit with zero violations.
• ✓Unified fleet management: Property managers monitor all 23 units from one dashboard; 5 potential faults resolved pre-emptively via predictive alerts.
• ✓Reference-site effect: The base became a flagship reference site for Zhongguancun Science City, attracting 3 neighboring parks to adopt the same standardized backup-power model.

"Managing 23 generators across the base used to mean constant fire drills — especially in Beijing winters. Now the entire fleet is standardized, centrally monitored, and proven to start reliably even at -18°C. The cold-climate package and 6-second transfer have given our data center and biotech tenants complete confidence. It's the backbone our science park needed." — Director of Facilities, Yongfeng Industrial Base Property Management Office
