High-Altitude Power Solution Project

A telecom operator's plateau base station power assurance project at 4,500m altitude — zero interruptions, extreme cold start, and quad-stage dust protection.

Project Background

A leading domestic telecom operator launched an open tender for a comprehensive power assurance upgrade across dozens of high-altitude base stations on the Qinghai-Tibet Plateau. Located at elevations above 4,000m, these sites suffered from extreme low temperatures (-25℃ to -30℃), thin air, intense ultraviolet radiation, and high dust concentrations (PM10 ≈ 500μg/m³). Existing gensets failed to start in winter, causing frequent communication outages and annual operator fines of up to 800,000 yuan. The project demanded a one-stop solution covering environmental hardening, zero-interruption paralleling, intelligent O&M, and full compliance.

01. Bidding Purpose & Process

Bidding Objectives

  • Reliable cold-start at -30℃ with zero winter failures.
  • Quad-stage dust protection for PM10 > 600μg/m³.
  • N+1 redundant paralleling with ≤±2% voltage deviation.
  • Remote cloud monitoring to cut on-site maintenance.
  • Full lifecycle cost control and local spare-parts support.

Bidding Process

  • Prequalification: Plateau project track record and cold-start certification reviewed.
  • Technical Bid: Environmental hardening and paralleling schemes evaluated on-site.
  • Commercial Negotiation: Total cost of ownership and SLA response time assessed.
  • Award: NovArk Power won on technical superiority and plateau-proven reliability.

02. Post-Award Objectives

Cold-Weather Start

10-second start at -30℃ via intake preheating and dual-battery redundancy.

Dust Immunity

Quad-stage dust protection with positive-pressure cabin for plateau dust storms.

Zero Interruption

≤8ms grid-to-unit transfer with N+1 paralleling and ≤±2% voltage deviation.

Smart O&M

AI-driven cloud platform to predict faults and reduce site visits by 90%.

03. Status Before Intervention

Prior to NovArk's involvement, the operator's plateau base stations relied on legacy gensets never engineered for extreme altitude. The combination of thin air, severe cold, and dense dust produced chronic failures:

  • Winter Start Failures: Units failed to start below -20℃, causing 12+ annual communication outages.
  • Dust Ingress: Filters clogged within weeks; abrasive dust accelerated engine wear.
  • No Remote Visibility: Fuel theft and low-oil events went undetected until sites went dark.
  • High OPEX: Frequent emergency dispatches pushed annual maintenance above 200,000 yuan.
  • Financial Impact: Service-level breaches triggered operator fines totaling ~800,000 yuan/year.

OPEX Reduction

Since deployment, the plateau cluster has recorded zero winter start failures and zero communication interruptions for two consecutive years. The operator's 800,000 yuan annual fine exposure has been fully eliminated, and the project was recognized by the operator as a "High-Altitude Guarantee Benchmark." Remote diagnostics reduced on-site emergency dispatches by 90%, lowering annual O&M costs by approximately 30%.

The success led to a framework agreement expansion, with NovArk Power becoming the long-term strategic power assurance partner for the operator's plateau network.
