GCSC is developing Griddle, a vendor-agnostic digital twin platform that makes fragmented, largely unmetered distribution grids observable, fusing deterministic power-flow physics with data-driven state estimation into a single real time source of truth for grid operators.
The problem
On fragmented grids with isolated connection points and largely unmetered branches, conventional monitoring cannot reconstruct real time flows. Physics-only state estimation is under-determined precisely where metering is absent, the branches an operator most needs to see.
Scope · GCSC
A software-only, vendor-agnostic platform. A deterministic power-flow core provides an interpretable physical backbone; a data-driven observability layer generates learned load pseudo-measurements and cross-validates them against every available meter, SCADA, and IoT source, yielding accurate network state even on unmetered branches, with explicit confidence bounds rather than a black box.
Full stack delivery
- Digital twin core: deterministic power-flow model as an interpretable physical backbone.
- Data-driven observability: learned load pseudo-measurements, cross-validated against every available meter, SCADA, and IoT source.
- Capacity intelligence: real time network state and per-branch, per-substation, and per-connection-point capacity limits, exposed as a single source of truth.
- Vendor-agnostic integration: works across suppliers' hardware and existing metering infrastructure, no proprietary sensors required.
- Governed access: role-based data access so each grid operator sees only its own data, preserving upstream validation authority.
