Resilient infrastructure for critical care

Hospital uptime, delivered as a service.

Winko builds and operates the infrastructure a hospital cannot afford to lose: electricity, oxygen support, cold chain, connectivity and monitoring. One accountable operating layer, contracted for uptime rather than for a list of components.

400+ Days without a critical-infrastructure failure at the Liberia reference site
6 Countries where Winko operates across sub-Saharan Africa
7 Hospital sites deployed, contracted, awarded or assessed
1 Standard architecture, configured to each hospital's clinical envelope

The problem

Hospitals experience outages as failed clinical workflows, not missing kilowatt-hours.

A laboratory that cannot run samples. A pharmacy whose cold chain has broken. An oxygen concentrator that stops mid-shift. Where the grid is unreliable, these are daily events, and they are met with diesel generators, fragmented equipment donations and nobody accountable for the whole.

Hospitals do not need another collection of solar components. They need one operating layer for the infrastructure that cannot fail, with monitoring, maintenance and incident response built in from day one.

Uptime is the product.

The platform

Standardised architecture. Configurable clinical envelope.

CriticalCareOS brings power, oxygen support, cold chain, connectivity, monitoring and maintenance under one accountable operating model. The architecture repeats from hospital to hospital. What each hospital protects is chosen with the hospital.

The CriticalCareOS envelope

Solar generation

Sized to the protected load

Battery storage

Rides through outages

Medical oxygen

Concentration and supply

Cold chain

Pharmacy, blood, vaccines

Connectivity

Clinical and data systems

Remote monitoring

Uptime, incidents, service

Delivered as one containerised deployment. The hospital contracts for uptime across the envelope, not for a list of components.

Winko standardises

The assessment methodology, system architecture, integration approach and deployment sequence. Then the monitoring, maintenance, local technician model, incident response, reporting and accountability for uptime.

The hospital configures

Physical capacity and the protected clinical envelope, chosen against its own loads, priorities and growth.

Why it scales

Hospitals of very different sizes sit in the portfolio. That variation does not work against productisation, because capacity and envelope are precisely the parts meant to be configured.

CriticalCareOS containerised deployment concept
CriticalCareOS reference unit: solar generation, battery storage, cold chain, connectivity and monitoring packaged as one hospital uptime module.

Engagement levels

Start with the services the hospital cannot afford to lose.

Entry

Protects the laboratory, pharmacy and main store: the services nearly every patient passes through.

Extended

Adds maternity, theatre, blood bank and imaging to the protected envelope.

Whole-hospital essential services

Hospital-wide critical infrastructure under a single uptime contract.

How it deploys

Three stages, the same every time.

01

Assess

Map critical loads, cold chain, oxygen, connectivity, generator and grid performance. The output is a clinical case and a sized envelope, not a component quote.

02

Configure and implement

Define the architecture, replace weak distribution boards where needed, procure, install and commission.

03

Train and maintain

Establish local ownership, remote visibility, incident response and donor-grade reporting. Maintenance is part of the product, not an aftercare function.

Next: a factory-built reference design

Deployments today are assembled substantially on site. The next stage is a factory-built CriticalCareOS reference unit that arrives pre-integrated, with the aim of cutting deployment time by roughly an order of magnitude. The design is in progress.

Impact at scale

One proof point, now a multi-country portfolio.

Each deployment is described by the clinical infrastructure it protects. Live, implementing, awarded and assessed are different milestones, and Winko reports them separately.

Unit economics

What one dollar delivers

Every $1 deployed into critical hospital infrastructure translates into measurable healthcare, energy, resilience and climate outcomes.

$1 of critical infrastructure
13 patient visits supported

Lifetime unit economics for the laboratory and pharmacy critical services at a reference facility serving about 100,000 patient visits a year: roughly $0.075 of infrastructure cost per visit over the life of the system.

4.9 kWh Electricity delivered
0.5 L Diesel avoided
1.25 kg CO2 emissions avoided
18 min Critical-service power protected

Putting those numbers in perspective

$43 One 20-litre jerrycan of diesel avoided
$800 One tonne of CO2 emissions avoided
$3.26 One hour of critical-service power protected during a grid outage
