Patent-Pending Manufacturing Intelligence
Real-Time Manufacturing Activity Signals From Industrial Electricity Demand
The Supply Manufacturing Index (SMI) reads industrial electricity demand daily across 8 US power grids to detect manufacturing slowdowns and surges up to 24 hours before any government report. While traditional indicators like Industrial Production (IPMAN) publish monthly with a 30-45 day lag, the SMI delivers daily manufacturing activity signals derived from real-time EIA Grid Monitor data with patent-pending weather normalization.
Manufacturing consumes large, predictable amounts of electricity. When factory output changes, electricity demand changes. The SMI isolates the manufacturing signal from seasonal heating and cooling variation using a proprietary thermodynamic normalization formula, then compares against rolling baselines to detect deviations from normal industrial activity patterns.
Why Traditional Manufacturing Data Falls Short
The Federal Reserve's Industrial Production Index (IPMAN) describes March activity but isn't published until mid-April. ISM PMI surveys are monthly snapshots. Supply chain managers using these sources are always operating on stale data.
National indicators average away regional disruptions. When Winter Storm Uri shut down Texas manufacturing in February 2021, national IPMAN barely registered it. Regional crises that devastate specific supply corridors disappear in aggregate statistics.
PMI and regional Fed surveys measure sentiment, not activity. Purchasing managers report what they think is happening. The SMI measures what is actually happening -- real electricity being consumed by real factories, every day.
8 US Grid Regions Monitored Daily
The SMI provides manufacturing activity signals for each of the 8 major US power grid regions independently. This regional granularity is critical for supply chain operations because manufacturing disruptions are almost always regional, not national.
How the Supply Manufacturing Index Works
The EIA Grid Monitor publishes electricity demand data for all US grid regions hourly. This is the rawest, most immediate measure of economic activity available from any government source. The SMI ingests this data continuously.
A patent-pending thermodynamic normalization formula removes heating and cooling demand from the raw electricity signal. Using Heating Degree Days (HDD) and Cooling Degree Days (CDD) from NOAA aviation weather stations, the SMI isolates the portion of electricity demand attributable to industrial activity rather than climate.
EIA monthly sector-level retail sales data separates industrial demand from commercial loads. This filters out data center growth, EV charging infrastructure, and commercial electrification that would otherwise contaminate the manufacturing signal -- particularly in regions like PJM where Northern Virginia data centers have shifted the demand mix significantly.
Normalized manufacturing demand is compared against rolling monthly baselines recalculated daily. Deviations from baseline indicate manufacturing activity changes -- positive deviations signal increased production, negative deviations signal slowdowns or shutdowns.

NOAA Aviation Weather -- Temperature data from 21 airports used to calculate Heating and Cooling Degree Days for weather normalization. Source: Aviation Weather Center (aviationweather.gov).
EIA Sector-Level Retail Sales -- Monthly electricity retail sales by sector (industrial, commercial, residential) used to calculate industrial demand share for each grid region.
Federal Reserve FRED -- Industrial Production Index (IPMAN), Capacity Utilization (MCUMFN), ISM PMI (NAPM), and regional Fed manufacturing surveys used as validation benchmarks against the SMI signal.
Who Uses Manufacturing Activity Signals
Monthly government reports arrive 30-45 days after the fact. By the time IPMAN confirms a manufacturing slowdown, your inventory strategy is already wrong.
The SMI provides daily manufacturing activity signals across 8 US regions. See output changes forming in real time and adjust sourcing before competitors relying on monthly data.
Regional manufacturing disruptions go undetected in national averages. A plant shutdown in Texas doesn't show up in national industrial production figures.
8-region granularity means you see ERCOT collapse during a grid crisis while other regions operate normally. Reroute production and sourcing to unaffected regions within hours, not weeks.
Manufacturing demand drives commodity consumption, but you're trading on lagging indicators.
Daily manufacturing activity signals provide a leading indicator of industrial demand for metals, chemicals, and energy. See demand shifts up to 24 hours before they show up in commodity order flows.
Freight volume depends on manufacturing output. Capacity planning relies on outdated production estimates.
Regional manufacturing signals help forecast freight demand by corridor. When MISO shows sustained output increases, Great Lakes freight volumes follow within days.
Validated Against Major Disruptions
The SMI has been backtested against every major US manufacturing disruption since 2020. In each case, the electricity demand signal detected the disruption days to weeks before official government reports confirmed it.
Detected factory closures daily as they happened. IPMAN published 6 weeks later.
ERCOT regional signal collapsed immediately. National indicators missed it entirely.
Persistent daily weakening visible weeks before ISM PMI confirmed contraction.
Identified non-manufacturing electricity growth contaminating raw signal, leading to sector isolation methodology.
