Continuous resilience assurance

If the grid fails right now, which vital services stay powered — and for how long?

Serenis is a vendor-neutral software platform that continuously assesses, verifies, and predicts the resilience of a healthcare facility's critical power chain — turning a once-a-year inspection into live, ongoing assurance.

The blind spot

The chain is proven on a handful of days. Patients depend on it every one.

French facilities must switch vital equipment to backup power in under half a second, hold at least 48 hours of autonomy, and test their generators on a fixed cadence. Accredited bodies confirm all of this — but only on the days they are on site.

48 hAutonomy of the safety supply · short-stay MCO
12 +Generator tests a year, on fictitious and real load
Verified on audit days only.

COFRAC-accredited bodies such as APAVE and DEKRA confirm the installation is ready — on the few days they visit. For the rest of the year the chain runs unverified.

Failure appears at the switchover.

Equipment that passes a periodic test can still fail under real load on the day it is needed. The weak point is timing, not hardware.

The exposure sits with one person.

Responsibility for the safety supply rests with the head of the establishment, who carries the legal and personal liability yet has no continuous proof that the chain will hold.

2001 · Centre Hospitalier Lyon-Sud

The generators ran. The chain did not.

Two brief microcuts hit the grid. The generators started, but the plant controller went into safety mode and blocked distribution to the building. An operating theatre lost normal power during surgery.

1998 · Hôpital Édouard-Herriot, Lyon

Backup networks and generators failed to start.

During a night-time outage, neither of the two backup networks nor the three generators started. Around 720 patients were on site, dozens in intensive care; the most critical were evacuated.

The platform

One model for the whole chain. Three layers you adopt in sequence.

Serenis is delivered as a single platform in three layers. A facility can start with the first alone and add the others as it sees the value — which lowers the barrier to the first purchase and builds the expansion path into the product itself.

Compliance & electronic logbook

Replaces manual test record-keeping with an automatic compliance log and an audit-ready dossier. It removes a tedious administrative burden, protects the establishment director, and pays for itself early — so it asks for no large upfront decision.

Available Q4 2026

Continuous monitoring & prediction

Models the whole chain, verifies readiness continuously against the rules and the equipment's limits, locates the weak link wherever it sits, and predicts failure as connected sites build the dataset.

Orchestration of optimisation assets

As facilities add battery storage and solar, Serenis coordinates these non-critical assets within the same reliability model — so new equipment strengthens resilience instead of adding complexity.

Later phase

The whole chain, not one node

Models every link from the grid to the vital socket and finds the weak point wherever it sits.

Continuous readiness

Verifies the chain against the rules every second, not on a handful of test days. Prediction is added as the dataset grows.

A clinical-continuity map

Links each circuit to the service it feeds, so the answer reads in patient terms — which departments stay powered, and for how long.

An automatic regulatory dossier

Records every test, switchover, and anomaly and assembles the audit-ready evidence on its own — no manual logbook.

Orchestration of the energy stack

Coordinates non-critical storage and solar within the same reliability model, so new assets strengthen resilience.

Explore the live digital twin and trigger a grid loss to watch the chain respond.

Serenis observes, verifies, and predicts. It is not in the safety-power control loop and does not control the safety supply. Orchestration touches only non-critical storage and solar — so the platform stays outside the safety-critical perimeter by design.

Live digital twin

A live model of the protected chain — put it to the test.

Serenis builds a digital twin of the facility's power chain and simulates its behaviour under real full-load conditions. Trigger a grid loss below and watch the transfer switch select backup power, while the platform tracks which clinical services stay online.

// Live view — the whole chain is verified continuously against the rules and the equipment's limits. Weak link: none detected. // Grid lost. The transfer switch selected backup power in under 0.5s. Vital services remain powered; non-critical loads are shed to extend autonomy.

Light to deploy, quick to trust

The view above is an illustrative model. On a real site Serenis reads the facility's existing telemetry and adds light, non-intrusive sensors only where blind spots exist, notably on the switchover chain.

A pilot starts on one or two sites, which limits integration risk and earns the trust of medical and technical teams before any wider rollout. Because the platform observes rather than controls, it never sits between the generator and the patient.

What makes it defensible

The moat is a model, not a device.

Serenis is built from four elements that competitors cannot simply buy. Together they compound — the more sites connect, the sharper the model becomes.

Busbars, breakers, transfer switch, distribution — Serenis models every link as one system rather than watching a single node. Illustrative image.
01

A whole-chain reliability model

A digital twin of the protected power chain, simulated under real full-load conditions. It turns telemetry from across the chain into one predictive view of resilience.

02

A clinical-criticality model

A second model weights each circuit and service by its importance to patient safety, so reliability is always read through clinical risk. This is where engineering meets medicine, and clinicians co-design it.

03

A proprietary French dataset

A longitudinal record of real backup-power behaviour in French facilities — switchover events, auto-start failures, battery-degradation curves, load profiles. It cannot be bought, and it compounds with every connected site.

04

A French validation partner

To ground the clinical and reliability claims in independent testing, Serenis is establishing a planned validation partnership with a French engineering school or a hospital biomedical-engineering department.

Model development, reliability engineering, and clinical validation are research and development carried out in France.
The opportunity

A recurring market, created by regulation.

The need is not discretionary. French facilities must secure their power supply by law, under two regimes, so the spend recurs every month and every year — for thousands of sites, regardless of the economic climate.

Roadmap

From proof to platform.

The plan ties product milestones to the commercial and data milestones that justify each stage, so technical progress and market progress advance together.
