Substation Automation RFQ Intake

This form is built for electric utilities, cooperatives, industrial facility owners, EPCs, substation automation engineers, and system integrators sourcing IEC 61850 automation systems, RTU upgrades, bay controllers, communications gateways, and SCADA integration for new and existing substations.

  • Automation system type — new SAS, RTU upgrade, IEC 61850 migration, bay controllers, or HMI replacement
  • Substation voltage class, number of bays, existing SCADA platform, and existing IED/relay manufacturers
  • Communications protocols — IEC 61850, GOOSE, DNP3, Modbus, IEC 60870, OPC-UA, and time synchronisation
  • NERC CIP classification, cybersecurity requirements, factory acceptance test, and SCADA integration point count

For Electric Utilities and SCADA Integration

Capture substation voltage class, number of bays, existing SCADA platform, required protocols (IEC 61850, DNP3, Modbus), SCADA point count, redundancy requirements, NERC CIP classification, and utility specification compliance.

For IEC 61850 Migration and Process Bus

Support IEC 61850 migration projects — from legacy serial protocols to station bus and process bus architectures — including GOOSE schemes, merging units, sampled values, SCD file delivery, and IEC 61850 conformance testing requirements.

For Cybersecurity and NERC CIP Compliance

Collect NERC CIP impact classification, IEC 62351 cybersecurity requirements, IEEE 1686 IED security capabilities, encrypted communications, VPN remote access, vendor cybersecurity documentation, and factory acceptance test requirements.

Substations

1. Automation System Type and Project Scope

Select the substation automation system type and project scope. Substation automation encompasses IEC 61850-based systems, remote terminal units (RTUs), bay control units (BCUs), station HMIs, communications gateways, and SCADA integration.

Automation System Type

2. Application and Substation Configuration

Identify the substation type, voltage class, number of bays, and the context of the automation project — new substation or retrofit of an existing system.

Primary Application

3. Communications Protocols and IEC 61850 Requirements

Select required communications protocols. Modern substation automation systems typically use IEC 61850 for bay-level communications and DNP3 for SCADA communications. Legacy systems may use Modbus or IEC 60870.

Protocols Required

4. Hardware Components and System Architecture

Specify required hardware components. The system architecture — centralised vs. distributed — determines whether a station-level RTU or gateway collects data from all IEDs, or whether bay controllers handle local control with a station bus.

Hardware Components Required
System Architecture

5. SCADA Integration, HMI, and Remote Access

Specify SCADA integration requirements, station HMI features, historian, and remote access needs. The substation automation system must interface reliably with the control centre SCADA platform and support field personnel.

SCADA and HMI Requirements

6. Standards, Cybersecurity, Testing, and Documentation

Select applicable standards, NERC CIP requirements, and testing and documentation needs. Substation automation systems at BES (Bulk Electric System) substations are subject to NERC CIP cyber system requirements.

Standards, Cybersecurity, and Documentation

7. Contact, Delivery, Uploads, and Notes

Quote Type
Support Required

Upload one-line diagrams, equipment lists, relay settings, utility fault current, previous studies, models, drawings, RFP documents, site standards, or photos.
