Protective Relays and RTAC Equipment

The City of Rocky Mount, North Carolina, issued an informal Request for Quotation (RFQ) for the procurement of microprocessor-based protective relays and real-time automation controller (RTAC) equipment necessary for a substation upgrade. The solicitation, posted on April 7, 2026, with a deadline of April 14, 2026, seeks quotations for three primary components: a transformer protection relay featuring dual-winding current differential protection, phase and ground overcurrent protection, and event reporting capabilities; a feeder protection relay with phase and ground overcurrent protection, voltage-based protection functions, and disturbance recording; and an industrial-grade RTAC serving as a substation data concentrator with an Intel Atom x5-E3940 Quad Core processor, minimum 8 GB RAM, and 480 GB solid-state drive. All equipment must be new, utility-grade devices supplied by a single manufacturer to ensure full communication compatibility and interoperability. Vendors must submit comprehensive quotations including company information, pricing, lead times, warranty terms, and shipping terms via email to Fantashia.Dickens@rockymountnc.gov. The City will award the contract to the lowest responsive and responsible vendor at its discretion, reserving the right to reject any or all quotes.

All submitted equipment must support SEL communication protocols, Mirrored Bits communication for high-speed peer-to-peer messaging, and DNP3 protocol integration for SCADA systems, with full compatibility to the City's existing SEL-based communication architecture. Manufacturers must provide a minimum ten-year warranty on all equipment supplied. The solicitation does not indicate any specific set-asides for disadvantaged enterprises or restrictions on vendor types, allowing any qualified supplier capable of meeting the technical specifications and warranty requirements to respond. No incumbent vendors or current contractors are identified in the available documentation. The total purchase value is expected to be under $30,000.00, classifying this as an informal procurement; however, the exact budget allocation and potential award value are not specified beyond this threshold.
