Equipment Specification: Completeness Checklist & Templates
A readiness checklist and copy-paste technical spec templates — give everyone reading it the exact same complete information, so the quotes that come back are actually comparable.
Specification Completeness Checklist
Check off what you already have. Anything left unchecked is worth settling before the specification is issued — it's the most common reason responses come back inconsistent or need a second round of questions.
Spec Templates
Plain-text technical specification templates for three common categories — copy, fill in the blanks, and use them anywhere (not just here). Using the identical template to every bidder is what makes their quotes comparable.
Transformer Specification Template
TRANSFORMER -- TECHNICAL SPECIFICATION ================================================ Project: [name / number] Quantity: [ ] Rating: [ ] kVA/MVA, [ ] phase Voltage class: Primary [ ] kV / Secondary [ ] kV Cooling class: [ ] (e.g. ONAN / ONAF / OFAF) Impedance (%Z): [ ] % (or "per standard design") BIL: [ ] kV Vector group: [ ] (e.g. Dyn11) Winding material: [ ] Copper / Aluminum Applicable standards: [ ] (e.g. IEEE/ANSI C57.12.00) Compliance/certifications required: [ ] Required delivery date: [ ] Delivery location: [ ] Domestic content / FEOC requirements (if any): [ ] Notes: [ ]
Switchgear Specification Template
SWITCHGEAR -- TECHNICAL SPECIFICATION ================================================ Project: [name / number] Quantity: [ ] sections / units Type: [ ] Metal-clad / Metal-enclosed / Low-voltage Voltage class: [ ] kV Continuous current rating: [ ] A Interrupting rating: [ ] kA Arc-resistant rating required: [ ] Yes/No -- Type [1 / 2 / 2B] Applicable standards: [ ] (e.g. IEEE C37.20.2, C37.20.1, or UL 1558) Compliance/certifications required: [ ] Required delivery date: [ ] Delivery location: [ ] Notes: [ ]
Battery Energy Storage (BESS) Specification Template
BATTERY ENERGY STORAGE SYSTEM -- TECHNICAL SPECIFICATION ================================================ Project: [name / number] Quantity: [ ] Energy rating: [ ] kWh / MWh Power rating: [ ] kW / MW Chemistry: [ ] (e.g. LFP) Depth of discharge assumption: [ ] % Round-trip efficiency assumption: [ ] % Enclosure rating: [ ] (e.g. NEMA 3R) Safety certifications required: [ ] (e.g. UL 9540 / UL 9540A) FEOC-clean sourcing required: [ ] Yes/No Required delivery date: [ ] Delivery location: [ ] Notes: [ ]
Where this fits
Once your spec is solid, look the part up in the spec library to check ratings, configuration options and indicative lead time. The templates above are what you then hand to whoever builds it — Voltfield does not quote or supply anything.
Frequently asked questions
What should a complete specification for industrial or energy equipment include?
At minimum: the technical spec (voltage class, rating, standard), quantity, required delivery date and location, applicable compliance/certification requirements, budget range if you have one, and your commercial terms. Missing any of these is the most common reason responses come back inconsistent or hard to compare.
Why does every manufacturer need the exact same information?
If vendors receive different levels of detail, their quotes aren't actually comparable — one bidder might quote a cheaper unit because they weren't told about a certification requirement the others assumed. Sending an identical, complete spec to every bidder is what makes a bid comparison meaningful.
Are these templates specific to Voltfield?
No — they're generic technical specification templates you can send to any vendor, not just Voltfield. They're meant to help you solicit consistent, complete quotes across your whole bidder list.
