Fire safety, carried as a tracked obligation.
SunnyGrid80 Solar-Storage Plant
An 80 MW photovoltaic plant with a 40 MW / 80 MWh battery energy-storage system and its grid substation, modelled in ELANG as an audited reference to UL 9540A and IEC 62443 — a system-of-systems where the interfaces carry as much of the design as the boxes.

A system of systems, held together by its interfaces
PV, storage and substation are three systems that only work as one, and the risk lives in the interfaces between them — electrical, thermal, data and control.
The SunnyGrid80 model is the reference for interface-heavy design: every connection typed and traced, fire-safety and cyber assurance carried as first-class obligations rather than appendices.
Recipe and standards
Driven by the generic system recipe (ISO/IEC/IEEE 15288) with electronics and cyber assurance.
IEC 62443
Cyber assurance, carried as a tracked obligation.
ISO/IEC/IEEE 15288
The lifecycle the plant is taken through.
Baseline lifecycle with electronics and cyber standards
Model a grid-scale solar-plus-storage plant whose interfaces, fire-safety case and cyber-assurance obligations are all traced and checkable.
Frame
Frame the plant’s mission and grid-connection requirements.
Decompose
Decompose into PV, BESS and substation systems with typed interfaces.
Assure
Carry fire-safety (UL 9540A) and cyber assurance (IEC 62443) as tracked obligations.
Allocate
Allocate requirements across the sub-systems and their interfaces.
Verify
Close verification and reach production-ready conformance.
CDR — Critical Design Review
The design baseline and its supply have to be real before build.
Released baseline
Geometry, BOM and software baseline are released.
Qualified sources
Every part has a qualified source and a lead time.
Interface control
Every interface is controlled by an interface-control item.
Risk
Open risks are within tolerance.
Change any released item and everything downstream of it goes stale — the baseline cannot silently drift out from under a passed gate.

District energyEuroméditerranée District Energy NetworkA seawater-source district-heating network: two intake pumps and two seawater exchangers feeding three heat pumps, two backup boilers and a stratified thermal store, distributing through two network pumps and a differential-pressure valve to thirty consumer substations. The network is simulated; the city under it is not — every substation sits on its real IGN BD TOPO® building footprint in the Euroméditerranée quarter. It is a demonstration network on open data, not any operator's plant.
