Meilahti Tower Hospital UPS Project: Medical-Grade Power Case for Nordic Healthcare

Ⅰ. Project Overview

1. Basic Information
   • Project Name: Meilahti Tower Hospital UPS Project
   • Location: Helsinki, Finland
   • Application: Medical data centers and critical IT systems
2. Background
   • Hospital Profile: A renowned central hospital in southern Finland, with the tower wing constructed in 1965. The building’s exterior is protected by urban planning, making the renovation focus on upgrading internal power management infrastructure to meet modern energy efficiency standards, ensure critical application power supply, and reserve space for future expansion.

Ⅱ. Core Challenges

1. Energy Efficiency Optimization
   • Objective: Reduce operational costs and promote environmental sustainability of the power system.
2. Critical Power Assurance
   • Requirement: Upgrade power supply for critical loads such as emergency lighting and life support equipment to ensure medical service continuity and patient safety during emergencies.
3. System Scalability Design
   • Challenge: Anticipated growth in patient numbers requires the power system to have flexible expansion capabilities to avoid secondary renovations.

Ⅲ. Solutions

1. Hardware Deployment

• Equipment Selection: Three 300kVA online double-conversion line-frequency UPS units operated in parallel.

2. Core Technical Applications

• High Power Factor Design:
  • Output power factor reaches 0.8, and input power factor (with filter) increases to 0.95, reducing reactive power loss.
• Wide-Range Environmental Adaptation:
  • Supports wide input voltage and frequency ranges, adapting to power grid fluctuations in Northern Europe to ensure stable operation under extreme conditions.
• Strong Overload Protection:
  • Provides 5-second continuous overload and short-circuit protection, effectively withstanding startup impacts from medical equipment.
• N+X Parallel Redundancy Architecture:
  • Supports parallel connection of up to 6 UPS units of different models, enabling dynamic capacity expansion and fault tolerance, increasing system reliability by 40%.

Ⅳ. Project Achievements

1. Enhanced Power Reliability
   • The system meets the hospital’s 30-minute emergency power supply requirement. The power failure switching time for critical medical equipment is <4ms, with a zero downtime record throughout the year.
2. Energy Efficiency and Environmental Benefits
   • Compared with traditional UPS, annual power consumption is reduced by 25%, and carbon emissions are decreased by approximately 18 tons/year, complying with Finland’s National Green Hospital Standards.
3. Client Feedback
   • Facility management evaluation: “BKPOWER UPS exceeds expectations in reliability and scalability, providing a solid power foundation for the hospital’s digital transformation.”

Ⅴ. Project Conclusion

BKPOWER has helped Meilahti Tower Hospital achieve modernization of power infrastructure under building exterior constraints through online double-conversion line-frequency UPS technology and N+X parallel redundancy solutions. This project balances energy efficiency optimization, medical-grade reliability, and future scalability, setting a replicable benchmark for UPS applications in the European healthcare industry.
