Reliable Electricity for Climate-Resilient Healthcare in Viet Nam: Critical Services, Backup Power, and Safer Energy Choices

IMPLEMENTATION INSIGHTS · CLIMATE-RESILIENT HEALTHCARE

Last reviewed: October 25, 2026

A healthcare facility may have a stable connection to the electricity grid, an emergency generator, and an established maintenance program. Yet these arrangements do not necessarily mean that every essential clinical service can continue safely when the normal power supply fails.

A brief interruption may have little effect on administrative work but create serious concerns for equipment supporting critically ill patients. A generator may start successfully while certain clinical areas remain without power because they are not connected to the appropriate backup circuits. A battery system may provide temporary electricity, but its available capacity may be insufficient for the equipment that depends on it.

These situations illustrate an important distinction: having electricity, having backup power, and having a clinically reliable electricity supply are not the same thing.

Electricity supports almost every aspect of modern healthcare, from medical equipment, lighting, and communications to diagnostic services, refrigeration, water systems, and environmental controls. Its reliability affects not only whether a facility can operate, but also whether particular clinical activities can be performed safely.

Climate change adds further considerations. Flooding, severe storms, extreme heat, and other environmental pressures can affect electricity infrastructure, increase demand, or expose weaknesses in existing backup arrangements.

For healthcare organizations in Viet Nam, improving electricity reliability should begin with understanding which services depend on power, what happens when that power becomes unavailable, and whether existing arrangements provide the protection those services require.

This also creates opportunities to consider more efficient and lower-carbon energy solutions. However, reducing electricity costs or greenhouse gas emissions should not compromise electrical safety or the reliability of essential patient care.

The central question is not simply whether a healthcare facility has electricity. It is whether appropriate power is available, with the necessary quality and continuity, where and when safe care depends on it.

Why Reliable Electricity Matters for Patient Safety

On October 14, 2026, the World Health Organization (WHO) updated its fact sheet Electricity in Health-Care Facilities, emphasizing the importance of reliable electricity for healthcare delivery.

WHO identifies electricity as essential for medical equipment, safe childbirth, immunization, diagnostic services, emergency response, lighting, communications, and clean water supply. Reliable electricity also enables healthcare professionals to use technologies and infrastructure that support timely and appropriate treatment.

The publication highlights substantial international inequalities in electricity access. WHO estimates that close to one billion people in low- and lower-middle-income countries are served by healthcare facilities without reliable electricity or with no electricity access at all.

This estimate is drawn from evidence summarized in Energizing Health: Accelerating Electricity Access in Health-Care Facilities, published in January 2023 by WHO, the World Bank, the International Renewable Energy Agency, and Sustainable Energy for All.

The report includes findings based on national survey data from 27 low- and lower-middle-income countries collected during different years between 2015 and 2022. The estimate should therefore not be interpreted as a new measurement for 2026 or as evidence of electricity reliability in Vietnamese healthcare facilities.

Nevertheless, the findings illustrate why dependable electricity remains an important healthcare quality and equity concern.

The WHO/UNICEF Global Framework for Action 2024–2030 and the September 2025 report Essential Services for Quality Care also recognize reliable electricity as a fundamental requirement for healthcare quality, alongside water, sanitation, hygiene, and healthcare waste management.

However, access to electricity is only one dimension of reliability.

A healthcare facility may be connected to the grid but still experience brief interruptions, voltage fluctuations, internal distribution failures, or periods when the available supply does not meet operational demand.

The consequences depend on which services are affected.

An interruption to a nonessential administrative workstation may be inconvenient. The same interruption affecting certain life-supporting equipment or an ongoing clinical procedure may have much more serious implications.

Some medical devices have internal batteries or other safeguards that temporarily support operation. Others depend on external electricity or require additional protection against interruptions.

Even a short interruption may matter for some activities, while others may tolerate a longer interruption if appropriate clinical and technical arrangements are available.

Reliable electricity should therefore be assessed in relation to the healthcare functions it supports and the consequences of those functions becoming unavailable.

Identifying the Clinical Services That Need Protection

A practical assessment begins by identifying which healthcare activities depend on electricity and what level of continuity they require.

In a large hospital, this may involve operating rooms, intensive care units, emergency departments, neonatal care areas, diagnostic services, and other specialized clinical settings.

Medical devices such as ventilators, infusion pumps, patient monitors, anesthesia workstations, and laboratory analyzers may have different electrical requirements and backup capabilities.

Some devices include internal batteries, but their operating duration depends on battery condition, state of charge, device settings, maintenance, and manufacturer specifications. The presence of an internal battery does not automatically establish that equipment can continue functioning safely for the period required by a particular clinical situation.

Electricity also supports services that may be less visible to patients.

Medical oxygen systems may depend on electrically powered concentrators, compressors, control equipment, or monitoring systems, depending on their configuration. Other oxygen supply arrangements may have different electrical dependencies.

Laboratories, diagnostic imaging services, sterilization equipment, pharmacy refrigerators, vaccine storage systems, and information technology networks may also be affected by electricity interruptions.

Environmental systems can be equally important. Ventilation, cooling, temperature control, water pumping, and other building services may support conditions required for particular clinical activities.

However, not every electrical load within a healthcare facility requires the same level of protection.

The appropriate priority depends on the consequences of interruption, the type of service provided, the equipment involved, and the availability of suitable alternatives.

For example, a facility providing dialysis services may need to consider the electrical requirements of treatment equipment and the supporting systems necessary for safe dialysis operations. A primary care clinic may have fewer complex technical dependencies but still require reliable electricity for selected essential activities.

A large referral hospital and a small outpatient clinic should therefore not be expected to adopt identical backup configurations.

The more useful approach is to identify which clinical functions require protection and determine the appropriate arrangements through qualified clinical and technical assessment.

Looking Beyond Equipment Inventories

Healthcare organizations often maintain equipment inventories for maintenance, procurement, and asset management. These records are useful, but they may not explain how electrical systems support actual patient care.

For example, knowing that a hospital owns several ventilators does not necessarily establish which electrical circuits supply them, whether those circuits have suitable backup arrangements, or how long the devices can operate during an interruption.

Similarly, an inventory of refrigeration equipment may not show whether required storage conditions can be maintained throughout a disruption.

A more informative assessment connects equipment with the clinical activities and patients that depend on it.

Clinical personnel can help identify which procedures are time-sensitive, which equipment is essential, and what consequences could arise if electricity becomes unavailable. Engineering and facilities teams can explain how electricity is distributed, which circuits receive backup power, what technical limitations exist, and how relevant systems are maintained.

Biomedical engineering or medical equipment specialists may contribute information about device specifications, electrical safety, power requirements, and internal battery performance. Healthcare managers and quality professionals can help connect these findings with organizational responsibilities, patient safety priorities, and available resources.

This multidisciplinary perspective matters because an electricity system may appear adequate from an engineering capacity perspective while remaining insufficient for a particular clinical activity.

The assessment also needs to remain current. Changes in equipment, clinical services, patient volumes, room functions, or building configuration can alter electrical requirements. A backup arrangement designed for an earlier stage of a facility's development may no longer provide suitable protection after new services or equipment have been introduced.

Understanding Different Types of Electricity Failure

Not all electricity interruptions arise from the same problem.

External electricity supply may be affected by severe weather, damaged infrastructure, or other grid-related events. Internal failures may involve transformers, switchgear, distribution circuits, protective devices, or individual equipment.

Voltage fluctuations and other power quality problems can also affect sensitive medical equipment without causing a complete loss of supply.

A brief interruption during transfer from the normal supply to a backup source is different from a prolonged grid outage. An internal circuit failure may affect one department, while a wider supply disruption can affect an entire facility.

A generator may have adequate nominal capacity but be unable to support all connected loads under actual operating conditions. Conversely, a suitable backup source may be available, but the transfer or distribution system may not function as expected.

Installing a generator therefore does not resolve every potential cause of electricity failure.

Climate-related pressures can make existing vulnerabilities more significant.

Flooding may damage electrical equipment located in exposed areas. Extreme heat may increase cooling demand or affect equipment operating conditions. Severe storms can damage external electricity infrastructure or interfere with access to maintenance and repair services.

In coastal areas, moisture, saline conditions, and other environmental factors may also affect exposed electrical equipment.

However, not every power failure is caused by climate change.

Poor maintenance, unsuitable installation, deteriorating equipment, inadequate capacity, and other operational problems can undermine reliability even under normal weather conditions.

Climate-resilient electricity management needs to consider these ordinary weaknesses alongside credible environmental hazards.

The objective is to strengthen the systems that healthcare services depend on rather than treat climate resilience as a separate activity disconnected from routine facility management.

What Generators, UPS Systems, and Batteries Actually Provide

Backup electricity can be supplied through different technologies, but those technologies do not necessarily perform the same functions.

An emergency generator may provide an alternative electricity source when the normal supply becomes unavailable. Its effectiveness depends on suitable design, capacity, fuel availability, starting arrangements, maintenance, electrical protection, and connections to the intended loads.

A generator that starts successfully during a routine inspection may still be unable to support required clinical services if the distribution system, connected loads, or operating arrangements are unsuitable. Generators also require attention to fuel handling, ventilation, exhaust, fire safety, and environmental impacts.

An uninterruptible power supply, commonly known as a UPS, serves a different purpose.

Depending on its configuration, a UPS can maintain temporary power during an interruption or support suitable power quality for connected equipment. This may be particularly important where even a short interruption could affect the equipment or clinical activity involved.

However, UPS systems have finite capacity and operating duration. Their performance depends on connected loads, battery condition, system design, and maintenance. The presence of a UPS does not automatically mean that an entire clinical department has uninterrupted electricity.

Battery energy storage systems may provide additional electricity capacity, support selected loads, or operate as part of a larger energy arrangement. Their suitability depends on storage capacity, power conversion equipment, control systems, electrical protection, thermal management, and the intended operating mode.

Some healthcare facilities may use combinations of generators, UPS systems, batteries, and other electricity sources.

These combinations can provide additional protection when properly designed and coordinated. However, the number of backup technologies installed does not, by itself, establish how reliable the overall system will be.

What matters is whether the complete arrangement provides appropriate electricity to the required activities, including during transitions between sources and throughout the intended operating period.

Why Electrical Distribution and Transfer Matter

Backup electricity is useful only if it reaches the equipment and areas that need it.

This depends on the design and condition of the electrical distribution system, including circuits, switchgear, protective devices, and arrangements for transferring between electricity sources.

Some clinical activities may require power to be maintained without an interruption that affects their safe operation. Others may tolerate a defined interruption under appropriate technical and clinical conditions.

The relevant requirements depend on the medical location, the equipment involved, the activity being performed, and applicable technical standards.

It would therefore be inappropriate to assume that one transfer time or one backup configuration is suitable for every healthcare setting.

For example, an emergency generator may require time to start and become available after the normal supply fails. Equipment requiring uninterrupted operation may need additional protection during that transition.

The system must also support the electrical characteristics of connected equipment. Nominal generator capacity or battery size alone may not establish that a system can support the intended loads. Starting currents, simultaneous demand, equipment sensitivity, and other technical factors can influence actual performance.

These matters require qualified engineering assessment.

For healthcare leaders, the governance issue is ensuring that electrical design and operational arrangements reflect clinical requirements.

Clinical personnel should understand which services are supported by backup power and what limitations remain. Technical personnel should understand which activities have particular patient safety implications.

Neither group should be expected to make decisions outside its professional expertise.

Reliable electricity depends on effective coordination between those responsible for providing power and those responsible for delivering safe patient care.

Verifying Backup Reliability Without Putting Patients at Risk

A backup electricity system should not be considered reliable simply because it has been installed or because preventive maintenance has been recorded.

Its performance needs to be understood under conditions relevant to the facility's operations.

Routine inspection and maintenance provide important information, but they may not reveal every weakness affecting the complete backup arrangement.

For example, a generator may operate successfully during a maintenance check without demonstrating that the intended clinical loads can be supported through the actual distribution and transfer systems. Similarly, a battery system may appear available even though its usable capacity has declined.

Healthcare organizations can benefit from a structured approach to reviewing equipment condition, maintenance findings, selected system functions, and corrective actions.

Where technically appropriate, testing may examine backup performance under representative loads and the operation of relevant transfer arrangements.

Such activities must be planned and conducted by qualified personnel according to applicable technical requirements, manufacturer instructions, and established safety procedures.

Testing should not expose patients to unnecessary risks or interrupt critical services without appropriate safeguards. Clinical teams may need to participate in planning when testing could affect ongoing care or sensitive medical equipment.

The results also need to be interpreted carefully.

A successful generator test does not necessarily demonstrate that every critical medical device is protected against brief power loss. A successful UPS inspection does not establish that the connected clinical service can operate throughout a prolonged outage.

Each test provides evidence about particular functions under particular conditions.

When problems are identified, the appropriate response may involve maintenance, replacement, redesign, clearer responsibilities, or changes to operational arrangements.

The purpose is not simply to complete a checklist. It is to develop reasonable assurance that important electrical systems can perform as intended and that identified weaknesses are addressed.

Climate Resilience Also Depends on Equipment Location

The resilience of an electrical system is influenced not only by its capacity and design but also by where its components are installed and the environmental conditions they experience.

Equipment that operates reliably during ordinary conditions may become vulnerable when exposed to flooding, excessive heat, moisture, or other environmental stresses.

For example, a healthcare facility may have a generator with sufficient capacity but locate important supporting equipment in an area vulnerable to water intrusion. The system may then become unavailable during the same event that interrupts the normal electricity supply.

Other dependencies can create similar problems.

Generators may require access to fuel, appropriate operating conditions, ventilation, and maintenance support. Battery systems may depend on suitable temperature control and fire safety arrangements. Distribution equipment may be vulnerable to environmental exposure or inadequate maintenance.

These relationships matter because the reliability of an entire system may be limited by a weakness in one critical component.

Healthcare organizations should therefore consider whether important electrical equipment is appropriately located, protected, operated, and maintained for the conditions it may face.

The appropriate measures will vary. An urban referral hospital, a coastal healthcare facility, and a rural clinic may have different environmental risks, infrastructure constraints, and available resources.

Not every facility needs to relocate equipment or install additional infrastructure. Such decisions should follow appropriate technical assessment.

The broader principle is that resilience requires understanding actual system vulnerabilities rather than assuming equipment designed for normal conditions will remain reliable under every environmental circumstance.

Solar Power and Battery Storage: Opportunities and Limitations

Renewable energy and energy storage technologies create opportunities for healthcare organizations to reduce dependence on purchased electricity, lower certain emissions, and potentially strengthen electricity reliability.

WHO's 2023 Energizing Health report examines different electricity access solutions, including solar photovoltaic systems, battery storage, generators, and hybrid configurations.

The report recognizes that decentralized energy systems can be useful, particularly where grid electricity is unavailable or unreliable.

However, renewable electricity generation and dependable backup power should not be treated as equivalent.

A conventional grid-connected solar photovoltaic system may reduce electricity purchased from the grid during normal operation. It does not automatically continue supplying electricity when the grid fails.

Many conventional grid-connected solar systems disconnect during a grid outage as part of their electrical safety arrangements.

Providing electricity during an outage requires a configuration specifically designed and authorized for that purpose, with suitable controls, protection, and supporting equipment.

Depending on the design, this may involve battery storage, other electricity sources, and arrangements that allow intended loads to be supplied safely while disconnected from the grid.

Even when battery storage is installed, operating duration depends on available stored energy, connected demand, battery condition, and system configuration. Solar generation also varies with weather, time of day, and other factors.

A rooftop solar installation should therefore not be assumed capable of supporting critical healthcare activities continuously without suitable technical assessment.

Hybrid systems combining different electricity sources may offer advantages, but their reliability depends on how the components are designed, operated, and maintained together.

Battery systems also introduce safety and operational considerations, including thermal management, electrical protection, fire risks, maintenance, and eventual replacement or disposal.

These limitations do not mean that renewable energy is unsuitable for healthcare facilities. They mean that energy choices should reflect the objectives they are expected to achieve.

A solar installation intended primarily to reduce electricity costs may require a different design from a system intended to provide backup power for selected clinical services.

For healthcare managers, understanding this distinction is important before making investments or communicating claims about improved climate resilience.

Lower-Carbon Electricity and Reliable Care Are Different but Related Goals

Electricity choices can influence a healthcare organization's environmental footprint.

Energy efficiency measures, renewable electricity, suitable storage systems, and other improvements may reduce electricity consumption or greenhouse gas emissions under appropriate conditions.

However, reducing emissions does not automatically improve electricity reliability.

A conventional grid-connected solar installation may reduce purchased electricity while providing no backup during a grid outage. An emergency generator may strengthen service continuity while continuing to depend on fossil fuels.

These outcomes should be evaluated separately.

Energy efficiency is often a useful starting point, particularly when avoidable consumption can be reduced without affecting essential clinical functions.

However, changes to cooling, ventilation, lighting, or other building systems should remain compatible with the requirements of the spaces and activities they support. Measures affecting medical equipment must also be consistent with manufacturer specifications and relevant professional requirements.

When considering renewable electricity or energy storage, healthcare organizations should examine both operational and environmental implications.

These may include expected electricity generation, reliability under relevant conditions, maintenance requirements, installation constraints, equipment lifespan, operating costs, and end-of-life management.

Claims about reduced emissions should be supported by appropriate data and clearly defined assessment boundaries.

A project should not be described as climate-resilient solely because it uses renewable energy. Likewise, a system should not be described as low-carbon without considering the evidence supporting that claim.

The appropriate objective is to pursue environmental improvements alongside, rather than at the expense of, safe and reliable healthcare services.

Making Energy Investments Around Clinical Needs

Electricity investments can involve substantial costs and long-term operational responsibilities.

A new generator, UPS system, electrical distribution upgrade, solar installation, or battery storage system may provide benefits, but the most appropriate choice depends on the facility's actual requirements.

Understanding clinical and operational dependencies should therefore come before selecting technology.

Once these needs are defined, qualified professionals can assess whether existing systems can be improved or whether additional equipment is necessary.

Investment decisions should consider more than the initial purchase price.

Installation, commissioning, testing, maintenance, fuel or electricity costs, replacement components, specialist support, and equipment lifespan may all influence the long-term value of a system.

An option with a lower initial cost may create greater operating or maintenance difficulties over time. A technically sophisticated system may also be unsuitable if the facility lacks the personnel, resources, or specialist support needed to operate it safely.

Procurement arrangements should clarify responsibilities for design, installation, commissioning, maintenance, testing, documentation, and corrective action.

Where external contractors are involved, their responsibilities should be clearly defined and coordinated with the healthcare facility's internal management arrangements.

The project should not be considered complete simply because equipment has been installed. Its practical value depends on whether the system can support its intended purpose and be operated, maintained, and verified throughout its useful life.

For healthcare leaders, electricity investment decisions should connect clinical needs, technical feasibility, financial sustainability, environmental considerations, and long-term accountability.

What This Means for Healthcare Facilities in Viet Nam

Viet Nam's healthcare facilities operate in diverse geographical and service environments.

Large referral hospitals may provide intensive care, surgery, specialized diagnostics, and other services with complex electrical requirements.

Smaller hospitals, outpatient clinics, and commune health stations may have different equipment, responsibilities, and resources.

Environmental conditions also vary. Coastal facilities may face particular concerns related to severe storms, flooding, moisture, and saline conditions. Other locations may experience different pressures involving heat, heavy rainfall, or local infrastructure vulnerabilities.

These differences make facility-level assessment important.

A solution suitable for a large urban hospital may not be appropriate for a small healthcare facility in a rural area. Conversely, a smaller facility may have a limited number of essential activities for which carefully selected backup arrangements could provide meaningful benefits.

It is important to avoid unsupported assumptions about electricity reliability across the Vietnamese healthcare system.

WHO's international estimates do not establish the proportion of healthcare facilities in Viet Nam with adequate backup electricity, the frequency of hospital power interruptions, or the actual performance of particular electrical systems.

Such conclusions require suitable national or facility-level data.

A more useful starting point is to understand the actual requirements and capabilities of individual healthcare organizations.

A facility with an emergency generator may need to review which clinical activities receive backup supply and whether those arrangements remain adequate.

Another may identify maintenance or equipment-related weaknesses. A third may be considering solar energy and need to distinguish between reducing electricity costs, lowering emissions, and providing emergency backup power.

These objectives may overlap, but they are not identical.

For Viet Nam, the practical priority should be to make energy decisions based on clinical requirements, credible technical information, and the circumstances of each healthcare facility.

Applying International Guidance Within Viet Nam's Legal Framework

Reliable electricity in healthcare facilities involves several areas of Vietnamese law and technical regulation.

These include electricity activities and safety, building electrical installations, fire prevention and rescue, and specialized requirements relevant to medical locations.

The Law on Electricity, No. 61/2024/QH15, dated November 30, 2024, took effect on February 1, 2025.

The Law provides a framework for electricity development, electricity activities, electrical safety, renewable energy, and the responsibilities of relevant organizations and individuals.

However, it should not be interpreted as prescribing one universal backup power configuration for all healthcare facilities.

The technical requirements applicable to a particular installation depend on its characteristics, intended use, location, and the relevant legal and technical framework.

An important national technical regulation is QCVN 12:2014/BXD, concerning electrical installations in residential and public buildings, issued under Ministry of Construction Circular No. 20/2014/TT-BXD.

At the time of this review, the regulation remained listed as effective in Viet Nam's national standards and technical regulations database.

QCVN 12:2014/BXD establishes mandatory technical requirements within its defined scope for the design, new construction, renovation, and repair of relevant electrical installations.

A particularly important reference for healthcare facilities is TCVN 7447-7-710:2006, Electrical Installations of Buildings — Part 7-710: Requirements for Special Installations or Locations — Medical Locations.

This Vietnamese national standard remains listed as effective and addresses electrical installations in medical locations to support the safety of patients and medical personnel.

It is technically equivalent to IEC 60364-7-710:2002 and is among the normative references identified in QCVN 12:2014/BXD.

This relationship is important because the applicability of a technical standard cannot always be determined solely by describing it as voluntary.

Where technical standards are incorporated or referenced through applicable mandatory regulations, contractual requirements, or other legally relevant instruments, the requirements arising from those references must be considered according to their scope.

At the international level, IEC 60364-7-710:2021 provides a newer edition concerning low-voltage electrical installations in medical locations.

However, the publication of a newer international edition does not automatically replace the Vietnamese national standard or make every provision of that newer edition legally mandatory in Viet Nam.

The scope of these standards should also be understood correctly. They address electrical installations in medical locations and should not be treated as substitutes for separate requirements applicable to individual medical electrical devices or medical electrical systems.

The relevant standards and their binding application must be determined according to current Vietnamese regulations, normative references, project requirements, and other applicable provisions.

Fire safety is another important consideration, particularly when installing or modifying generators, batteries, energy storage equipment, switchgear, or electrical distribution systems.

The Law on Fire Prevention, Fighting and Rescue, No. 55/2024/QH15, took effect on July 1, 2025.

Government Decree No. 105/2025/ND-CP provides detailed provisions and measures for implementing the Law. Certain provisions were subsequently amended by Decree No. 347/2026/ND-CP, which took effect on September 15, 2026.

Relevant technical requirements may also include QCVN 06:2022/BXD on fire safety for buildings and constructions, as amended by Amendment 1:2023, within its applicable scope.

These requirements should be considered according to the particular facility, installation, and project involved.

Renewable energy development is governed by a related but distinct legal framework.

Government Decree No. 58/2025/ND-CP, dated March 3, 2025, provides detailed provisions concerning renewable energy and new energy development under the Law on Electricity.

Decree No. 57/2025/ND-CP addresses direct power purchase arrangements between renewable electricity generators and large electricity consumers.

Both instruments were amended in certain respects by Decree No. 243/2026/ND-CP, dated June 26, 2026, which took effect on the same date.

The Prime Minister also issued Directive No. 10/CT-TTg on March 30, 2026, concerning stronger implementation of electricity saving and rooftop solar development.

These instruments provide relevant policy and regulatory context for energy efficiency and renewable electricity.

However, they should not be interpreted as creating a general requirement for every healthcare facility to install rooftop solar panels, batteries, or a particular type of backup generator.

Likewise, provisions concerning direct power purchase arrangements apply within their defined scope and should not be assumed applicable to every healthcare electricity consumer.

The obligations associated with a specific project may depend on its capacity, configuration, location, connection arrangements, intended use, construction requirements, fire safety considerations, and other circumstances.

Healthcare organizations considering energy investments should therefore obtain appropriate professional assessment of the technical and legal requirements applicable to their projects.

International WHO guidance can support professional learning and organizational improvement, but it does not replace Vietnamese law or authorize a healthcare organization to bypass applicable electrical, construction, or fire safety requirements.

For Climate & Health Vietnam, it is important to distinguish evidence-based professional education from facility-specific engineering design or legal compliance determinations.

Making Electrical Reliability Part of Healthcare Governance

Electrical systems are usually managed by engineering and facilities teams.

This is appropriate for their technical operation and maintenance, but the consequences of an interruption may extend across clinical departments and organizational functions.

A clinical team may know that particular equipment is essential for patient care without knowing whether it is connected to an appropriate backup circuit.

An engineering team may understand the electrical distribution system but not fully appreciate how a short interruption could affect an ongoing clinical procedure.

A procurement decision may introduce equipment with new electrical requirements, while a service expansion may increase demand beyond the assumptions used when the backup system was designed.

These examples show why coordination between clinical and technical personnel matters.

Healthcare leaders can help ensure that responsibilities are clear, important clinical dependencies are understood, and changes to equipment or services are considered when reviewing electrical arrangements.

Quality and patient safety professionals may contribute by identifying where electricity reliability intersects with existing safety processes, incident reviews, and improvement activities.

However, responsibility must remain aligned with professional competence.

Clinical personnel should not be expected to perform technical electrical assessments outside their expertise. Engineering personnel should not determine clinical priorities without appropriate input from responsible healthcare professionals.

Effective governance connects these different perspectives.

This may involve established communication arrangements, maintenance information, appropriate technical reviews, and procedures for escalating concerns that could affect patient care.

A separate electricity governance committee is not necessarily required. Where existing management systems already support effective coordination, they can be used to address relevant electrical reliability risks.

What matters is that important concerns are identified, responsibilities are understood, and corrective actions are completed.

Measuring Reliability Without Overstating Results

Healthcare organizations need useful evidence to understand whether their electricity arrangements are dependable.

The presence of a grid connection, generator, UPS, or battery system does not establish that every essential clinical function has the required level of protection.

A more meaningful assessment connects technical performance with the services that depend on it.

For example, a healthcare organization may review whether priority clinical loads have been identified, whether their backup arrangements are documented, and whether relevant systems have been tested under suitable conditions.

Maintenance records can provide information about equipment condition, while test results may demonstrate selected functions.

Records of electricity interruptions, equipment faults, corrective actions, and communication with affected departments may also help identify recurring problems.

However, each form of evidence has limitations.

The absence of a reported power failure does not prove that a system will perform correctly during a future interruption. A successful generator test does not necessarily demonstrate that all critical medical equipment is protected against brief power loss.

Similarly, an estimated backup operating duration may not reflect actual conditions if connected loads, battery health, or other assumptions have changed.

Evidence should therefore be interpreted according to what was assessed and under which conditions.

Healthcare organizations may develop proportionate internal indicators reflecting the needs of their services. These could include the completeness of critical-load identification, the status of relevant maintenance activities, the results of selected system tests, and the completion of corrective actions.

Such indicators should be described as locally selected measures unless formally adopted within another applicable framework.

Improvements in electrical reliability should also not be presented as automatically demonstrating better patient outcomes. Reliable electricity supports safe care, but clinical outcomes are influenced by many factors.

The purpose of monitoring is to understand whether essential electrical arrangements are functioning as intended, where weaknesses remain, and whether improvement actions have been effective.

What Climate & Health Vietnam Can Contribute

For Climate & Health Vietnam (CHVN), reliable electricity is a relevant area for evidence synthesis, professional learning, and implementation-oriented collaboration.

The subject connects climate-resilient healthcare with patient safety, essential service reliability, organizational governance, and environmentally responsible energy choices.

CHVN can contribute by explaining international evidence on electricity reliability in healthcare facilities and why electricity access should be distinguished from clinically appropriate continuity and backup arrangements.

It can also support professional discussion about identifying electrical dependencies, coordinating clinical and technical responsibilities, and interpreting evidence concerning backup power performance.

Another useful area of learning concerns the relationship between electricity resilience and lower-carbon energy.

Healthcare organizations may benefit from understanding what different technologies can and cannot provide, particularly when considering generators, solar systems, battery storage, and hybrid arrangements.

CHVN may facilitate exchanges among healthcare managers, clinical professionals, quality and patient safety personnel, environmental health specialists, engineers, researchers, and other relevant stakeholders.

Potential contributions include credible evidence summaries, educational resources, implementation discussions, and collaboration on identifying practical knowledge gaps.

These activities should remain within CHVN's actual expertise, institutional capacity, and applicable legal and professional boundaries.

CHVN should not present its educational materials as official WHO assessments or imply authority to certify electrical installations, determine engineering compliance, approve renewable energy projects, or establish mandatory technical requirements for healthcare facilities.

Where electrical design, load calculations, installation, system testing, fire safety assessment, project authorization, or legal compliance verification is required, appropriately qualified and authorized professionals or organizations should be involved.

CHVN's role is to make credible evidence more accessible, explain its relevance to the Vietnamese healthcare context, and encourage informed professional learning and collaboration.

This is consistent with a broader approach to climate-resilient healthcare in which quality, patient safety, governance, and practical implementation remain central.

Reliable Electricity Means More Than Keeping the Lights On

Electricity is often taken for granted in healthcare until it becomes unavailable.

Yet a functioning grid connection does not necessarily establish that essential clinical services have adequate protection against interruption. A backup generator does not automatically mean that every critical device will continue operating safely. A solar installation does not necessarily provide electricity during a grid failure.

These distinctions matter because the consequences of electricity interruptions depend on the services involved and the systems supporting them.

For Viet Nam, strengthening electricity reliability should begin with understanding clinical needs and the actual performance of existing arrangements.

Some healthcare facilities may need to improve maintenance or testing. Others may need to review electrical distribution, backup capacity, or protection for particular equipment.

Some may identify opportunities to improve efficiency or reduce emissions through suitable renewable energy and storage solutions.

The appropriate response will depend on the facility's services, infrastructure, environmental risks, and available resources.

Not every improvement requires major new equipment. Clearer responsibilities, better coordination between clinical and technical teams, and appropriate verification of existing systems can also contribute to safer and more dependable operations.

Environmental sustainability remains important, but it should be pursued alongside the requirements of safe care.

The most useful electricity investment is not necessarily the newest technology or the system with the greatest installed capacity. It is the arrangement that appropriately supports the healthcare services people depend on and can be operated and maintained reliably over time.

Climate-resilient healthcare requires more than access to electricity. It requires dependable power for essential care, backup arrangements that work when needed, and energy choices that support patient safety while contributing to long-term environmental sustainability.
