Gain a Fully Observable Grid
GridMapper automates keeping the topology in your GIS consistent with the grid in the field. Using what your smart meters actually measure, it verifies your topology data and shows you where your GIS record differs from reality, so your team knows exactly what to correct.
Where the Record Stops Matching the Grid
Efficient grid operation, fast outage response, and optimized field work all depend on reliable low-voltage topology data.
That data usually lives in your GIS, maintained through established update processes. But because those processes depend on people, errors and inconsistencies creep in. With every connection change in the field the risk of a mismatch grows.
Field crews then verify connectivity by hand, losses take longer to trace, and outages last longer than necessary – all of which shows up in SAIDI and SAIFI.
GridMapper closes that gap requiring far fewer field visits. It compares your GIS with what your smart meters actually measure and pinpoints where the two differ.
What Is GridMapper?
GridMapper reconstructs your low-voltage supply tree from your smart meter data – which customer is connected to which feeder, from which secondary substation, and on which phase.
It runs on the infrastructure you already have. No new hardware, and far less field work. You rolled out smart meters for billing and compliance.
GridMapper uses the same fleet for network operations, with no additional hardware investment.
Three Detection Modules Cover the Low-Voltage Network

Parent Feeder and Substation Localization
Detect the actual supply path of each delivery point, along its feeder to its secondary substation. This supports substation balance calculations, loss detection, outage prevention, and grid development planning.

Supply Path Topology Verification
Confirm that your GIS data matches the actual network and see exactly where it does not. Understand how your grid is truly connected, and reduce the cost of manual surveys.
Phase Connection Detection
Detect the phase connection of every consumption point, identify the root causes of phase asymmetry, and make better use of the grid capacity you already have.
No Digitalized Topology Yet?
GridMapper can identify and validate supply paths automatically from existing data such as GPS coordinates and open-source satellite imagery, which removes most of the manual reconstruction work.
How GridMapper Helps
Trust in Your Network Model
GridMapper assigns every connection point to its feeder, secondary substation and phase, with a confidence indicator for each. Where your GIS diverges, you see how and where.

Cut Manual Field Work
Fewer field surveys are required, reducing the operational cost of keeping your network topology accurate. Crews only need to visit locations where the model needs further verification.
Defer Reinforcement CAPEX
Assess hosting capacity against the actual network topology to identify where more DER can be connected and understand where grid reinforcement is needed.

Improve SAIDI and SAIFI
Faster fault localization cuts outage time and improves outage management. Knowing which customers are connected to affected feeders can boost customer service, enabling prompt notification and restoration.

Analytics You Can Rely On
Loss detection, fraud detection, quality-of-supply monitoring and planning all assume the supply tree is known. Verified topology makes that assumption safe.
How GridMapper Works
GridMapper infers the supply tree from the physics of the network. Your meter measurements and your GIS data are the entire input.
Data Capture
Smart meters already record the profile GridMapper needs. It arrives through your existing MDC/MDM channel, either as a standard AMI profile or as a compact topology signature generated inside the meter by the Topology Signature Calculator.
Topology Inference
Voltage at one smart meter reflects everything upstream, so GridMapper evaluates all meters together rather than one at a time.
GIS Reconciliation
GridMapper compares each relationship with your record and sorts it into a prioritized worklist.
Deployment
Cloud
GridMapper works with the profiles your MDC/MDM systems already collect, typically as 15-minute or 30-minute averages. Instantaneous readings work too, with reduced precision.
Edge
The Topology Signature Calculator runs inside the meter firmware and generates compact topology signature profiles delivered over standard DLMS/COSEM. Those signatures are the input: the topology itself is inferred centrally from all meters together.
Edge + Cloud
The meter produces the signatures, the cloud builds the topology model and refines it as your network evolves.
Start with a Discovery Project
A one-off analysis of the measurement data you already have.
We run GridMapper on a sample of your smart meter and GIS data and show where your record gets the topology right, and where it does not. You receive a report and an interactive deliverable overlaid on your original GIS.
