Ensuring reliability in expansion schemes

Area of Science:

• Healthcare Engineering
• Electrical Infrastructure Management
• Hospital Facility Planning

Background:

• Aging hospital electrical power supply assets (up to 20 years old) require assessment for reliability and security.
• Hospital expansion necessitates adaptation or replacement of existing power supply systems to meet increased demand.
• Unplanned power outages due to overloads or equipment failure pose significant risks to hospital operations.

Purpose of the Study:

• To evaluate the security and reliability of electricity power supplies in major London hospitals.
• To develop and describe a methodology for assessing hospital electrical infrastructure.
• To provide recommendations for enhancing the resilience of hospital power systems.

Main Methods:

• A comprehensive evaluation methodology was employed to assess electrical power supplies.
• The methodology aligns with the National Health Service (NHS) Estates Health Technical Memorandum (HTM) 2011.
• Site-specific assessments were conducted for several major London hospitals.

Main Results:

• Identified vulnerabilities in existing hospital electrical infrastructure.
• Quantified the risks associated with aging power supply assets and potential overloads.
• Provided specific recommendations for improving power system security and reliability.

Conclusions:

• A systematic approach to assessing electrical power supplies is essential for hospital resilience.
• Adherence to updated guidelines like HTM 2011 is critical for ensuring adequate contingency planning.
• Proactive evaluation and upgrades of hospital electrical infrastructure prevent critical service disruptions.
