Specification
Record the requested point list and the interval. If a supplier substitutes a coarser interval, the deviation stays visible beside the price.
Energy management system suppliers
Supplier matching starts when two quotations can be read against the same specification, the same quantity, and the same delivered scope. TerraFlow Supply prepares that comparison sheet. It does not award a contract and it does not replace the project engineer.
Ask each energy management system supplier to name the manufacturer, the exact model, the software revision, and the line items that are optional. A shared brochure for a product family is a clue, not evidence for the line you would buy.
Fields that make two offers comparable
Quantity
Match the count of hardware and the count of software seats. A site license quoted against a per-meter request is a different offer.
Delivered scope
Freight, duties, spare fuses, current transformers, and remote setup time belong in the scope column, not in a footnote that one bidder omits.
Supplier documents
Datasheet, drawing, protocol statement, and warranty text must name the quoted model. Ask for them. Do not treat a request as a completed review.
Exact-item file list
- Datasheet showing rated power or the controller supply range, voltage, and current where the hardware has those ratings.
- Network or panel drawing with port types and the enclosure rating the supplier claims for that model.
- Protocol implementation note for Modbus, BACnet, SunSpec, or another stated interface.
- Test or listing file when the supplier says it applies, bound to the same model identifier.
- Warranty text, software maintenance term, and a statement of what commissioning is excluded.
ISO 9001 evidence, when a supplier offers it, describes a quality system. It does not by itself approve an energy management configuration for a US interconnection.
Approvals that stay unresolved
Background: a buyer has three energy management system suppliers and a rooftop inverter fleet that already publishes Modbus registers. Process: the desk asks each bidder to map monitored assets to those registers and to state the stored data interval. Result: the comparison file shows matches and gaps. It does not declare the inverter fleet compatible.
- Whether the quoted license includes historical storage at a 15-minute interval or a live screen without stored history.
- Whether alarm workflow is an email notice, or a relay output the site can wire.
- Whether the integration interface needs a separate gateway that is absent from the unit price.
- Utility interconnection, structural review, and cybersecurity policy of the site owner.
See the inquiry rows and the electrical interface guide. The procurement brief uses the same evidence boundary.
Before award, agree with the proposed supplier on a pilot using the quoted gateway, meter type, firmware, and software license. Request a dated point export showing timestamps, units, scaling, and missing-data flags. The buyer's reviewer can compare it with the agreed point list and log deviations; this is a proposed acceptance path, not a test already performed by TerraFlow Supply. Keep the pilot charge, release quantity, recurring license cost, and any remote support charge in separate quotation cells.
Hand the requirement to the quote review
