# Squid > Squid is the model repository for power-system planning. It turns models from existing analysis tools (PowerFactory, PSS®E, IPSA, CYME, ETAP) into one standard, versioned network, so engineers and agents can validate data, build scenarios, run studies and publish decisions from the same governed source. Live with National Grid DSO. Backed by Y Combinator. Squid operates at the planning layer, not the control layer — it never writes to OT, SCADA or ADMS. Every model carries source lineage, version history, engineer approval and an audit trail. ## Pages - [Home](https://squid.energy/): What Squid is — the governed model repository for modern electricity networks, and how planning teams put it to work. - [About us](https://squid.energy/about): Who builds Squid — founders from National Grid, Octopus Energy and AWS, backed by Y Combinator (W26). - [Security](https://squid.energy/security): Security and compliance posture — permissioned access, model lineage and audit trails by design.
