The Voltfield Lead-Time Index

Methodology

Figures below are indicative market lead times and pricing ranges compiled from published market data, and are the same values that drive the lead-time flags across the catalog and the family reference pages. They are directional reference points for planning, not a quote for any specific order — final lead time and price come from whoever actually supplies the equipment. "Trend" reflects the recent direction (lengthening, holding, or shortening) based on the same market conditions covered in Insights.

Where each number comes from

Every row carries a basis label so anyone quoting this index can see exactly what kind of figure they're citing, rather than having to take the whole table on trust. We'd rather be specific about what's an estimate than let a modeled number get repeated as if it were a manufacturer survey.

Every figure currently published is modeled. As operator submissions are verified and published sources are matched to specific rows, those rows get relabeled — so the mix here is itself a signal of how well-corroborated the index is at any given time.

Embed this data on your site

The full index: every family with a published lead time

234 of the 242 equipment families in the reference carry an indicative lead time. They are listed in full below, longest first within each sector. The remaining 8 are commodity items stocked and shipped to order, where a single lead-time figure would not mean anything.

Every figure here is the same value rendered on the family and category pages — one source, so they cannot drift apart. All are indicative reference figures, not quotes.

Data Centers

50 families · 4 to 180 weeks

Renewables

42 families · 2 to 144 weeks

Battery Storage

20 families · 8 to 32 weeks

Oil & Gas

33 families · 2 to 36 weeks

Industrial Supply (MRO)

89 families · 1 to 8 weeks

Why lead times are the real constraint

Across every sector here, the equipment itself isn't the bottleneck — the wait is. Data center developers and utilities are bidding for the same transformer and switchgear capacity; see why transformer lead times stretch past 3 years for what's driving it and how to plan around it. Solar and storage buyers are layering FEOC and tariff compliance on top of already-long inverter and GSU lead times; see the FEOC compliance guide for what to document. Configure any of the equipment above against your exact spec on the Data Centers, Renewables, Battery Storage, or Oil & Gas sectors for a configuration-specific lead time.
