Case Study · Backup Power Standardization for Large-Scale Swine Farms
1 Client Background & Pre-Engagement Situation

Hunan Xinwufeng Co., Ltd. is a state-owned listed swine enterprise under Hunan province, with a breeding sow capacity exceeding 270,000 heads and annual output surpassing 3 million heads. It operates numerous modern, intelligent pig farms — including Yongzhou Chuwang, Hengyang Aggregation Zone, Wangcheng Quanxin, and Xinhua Building-Style Pig Farm — where environmental control, feed lines, drinking water, deodorization, and wastewater treatment all rely entirely on grid power.

Before we engaged, Xinwufeng's backup power across farming bases exhibited the classic "scattered, chaotic, risky" pattern:

  • Fragmented equipment sources: Each farm procured generators from local small vendors independently. Brands were mixed, power ratings were inflated, and units couldn't handle simultaneous startup of fans and water pumps.
  • Manual switching: Most sites only had manually-started units. During nighttime outages nobody entered the site, causing heat stress or cold shock.
  • High corrosion failure rate: In high-humidity, high-ammonia environments, standard control cabinets rusted and tripped within 6–8 months.
  • Environmental & biosecurity pressure: Open-frame units produced black smoke and loud noise, triggering complaints and biosecurity threats.
  • No pre-procurement standards: Supplier quality varied wildly and there was no unified acceptance checklist.
2 Tender Purpose & Bidding Process
2.1 Tender Purpose (2021 Annual Centralized Procurement)
  • ✓Transform "each-farm-buys-its-own" into a corporate-level centralized procurement model.
  • ✓Complete delivery + installation + commissioning within 20 days of order placement.
  • ✓Rigorously evaluate manufacturer authorization, farm project references, and after-sales systems.
  • ✓Address farm-specific requirements: corrosion resistance, silent operation, and ATS auto-start.
2.2 Bidding Process
  • Public tender managed by Hunan Zhonglongrui; pre-qualification eliminated unqualified traders.
  • Technical bids scored on tiered configuration, ATS + cloud monitoring, and 20-day delivery commitment.
  • Commercial bids evaluated within a control price of RMB 2.886 million.
  • We secured the leading comprehensive score and were awarded a designated-supplier slot.
3 Post-Award Objectives

The client's goal was not simply "buying a few machines" but establishing a "standardized backup-power foundation for all pig farms province-wide":

  • ✓Automatic adoption of standard models for any new farm.
  • ✓Unified acceptance checklist for legacy farm retrofits.
  • ✓Real-time visibility of unit status and fuel consumption during outages.
4 Why They Found Us (Differentiation & Trust Factors)
1. Proven livestock track record: Delivered 300/400 kW Yuchai corrosion-resistant units to similar farms.
2. Deep understanding of farm conditions: Expert knowledge of inrush current, ammonia corrosion, and noise impacts.
3. Early free technical assistance: Provided remediation plans for Hengyang farms facing environmental audits.
4. Centralized-procurement delivery capacity: Changsha warehouse enabled 18-day on-site delivery.
5. Willingness to manage O&M: Provided a unified dashboard for branch-company oversight.
5 Our Proposed Solutions & Recommendations

We did not sell "equipment" — we sold "uninterrupted-power capability."

Dimension Solution Proposed to Xinwufeng Pain Point Addressed
Model Standardization Tiered by farm type: 100–200 kW / 300 kW / 400–500 kW; all Yuchai Tier-3 + 20% power margin. Eliminated inflated ratings; fans and pumps start without tripping.
Farm-Specific Modification IP54 sealed cabinets + epoxy anti-corrosion + exhaust extended 15m outside. Resists ammonia corrosion and protects biosecurity.
Auto-Start & Monitoring ATS (3–8s auto-start) + IoT module + cloud dashboard. Unattended nighttime operation with zero mortality.
Silent & Eco-Friendly Silent canopy ≤75dB + DPX after-treatment + oil-water separation. Passes environmental assessments with no black smoke.
Delivery Standard Factory-supplied "Farm Acceptance Package": load-test + ATS video + SOP. Eliminates on-site acceptance disputes.
O&M Mechanism Quarterly inspections + 4-hour response + annual load-run drills. Shifts from "repair after failure" to proactive maintenance.
6 Implementation & Execution
  • Inventory & risk mapping: Audited 23 on-site sets; produced risk rating tables prioritizing key farms.
  • Pilot benchmark farm: Delivered 2×300 kW units at Yongzhou Chuwang with witnessed 0–8s switchover.
  • Phased batch delivery: Closed-loop process (arrival → lift → ATS tuning → 30-min load → sign-off) within 20 days.
  • Personnel empowerment: Trained farm electricians on the "Seven-Step Inspection Method" and cloud dashboards.
  • Redeployment & retirement: Retired units bought back and redeployed to non-livestock construction sites.
  • Monthly reporting: Submitted generation hours, auto-start counts, and fuel analysis to headquarters.
7 Final Results (Quantified Value)
0
Mortality incidents caused by grid outage
<2%
Unplanned downtime rate
100%
Units passing environmental inspection
↓12–15%
Reduction in total backup-power TCO
  • ✓Supply assurance: Zero mortality incidents during cooperation; longest autonomous run was 11 hours.
  • ✓Failure rate: Unplanned downtime dropped from ~15% to below 2%.
  • ✓Compliance: Zero generator-related complaints filed post-installation.
  • ✓Efficiency: Real-time monitoring of 40+ units; digital settlement and redeployment.
  • ✓Continued partnership: Designated as "Preferred Supplier" for subsequent farm expansions.
"In the past, every thunderstorm kept me awake — I was terrified the night patrol would miss a power outage. Now my phone pings 'Chuwang #2 Unit Auto-Started — 78% Load' and I can sleep soundly. This is the level of power assurance a state-owned pig farm deserves." — Farm Manager, Yongzhou Chuwwang Sow Farm
