For this snapshot, “Other sources” combines Nuclear and Other. A source appears as a separate row only when it has a positive reported value. The “Other” row contains EIA-reported Other, geothermal and any unmapped fuel types.

Latest hour with both country entries: . Canada and Mexico are EIA’s directly reported interchange rows. The US48 row is EIA’s authoritative total net interchange for this same hour and is also used in the headline. The reporting / reconciliation row is the exact difference needed to reconcile the shown country reports to that total; it is not an estimate for another country.
The headline uses that same aligned reporting hour, . It reads EIA total net interchange directly; it is not calculated from demand and generation. EIA normally receives total interchange about one day after operation and checked direct-pair interchange about two days after operation, so the feeds can differ after revisions, checks or missing submissions.

US electricity data by time period
Compare US demand, generation and net cross-border flow across each period. Past year and all time use daily EIA-930 operations from 2019 alongside monthly EIA-923 generation from 2001; their exact coverage differs and is shown with the data.

Understanding US power grid data
What does the latest generation mix show?
The latest snapshot compares the EIA fuel categories with positive reported generation for that hour. A category such as biomass appears as a separate row only when it has a positive reported value; the “Other sources” note lists exactly which displayed rows are grouped there. In each time view, Lower 48 EIA-930 demand, net generation and net cross-border flow use aligned observations. Demand is approximately generation plus net cross-border flow.
How recent is the data?
The day and week views use recent hourly EIA-930 operating data. The aligned national figures normally lag by about one day. Direct-interchange reports for Canada and Mexico normally arrive a day later and carry their own timestamp. This is not live grid telemetry.
How do the time ranges compare?
Past day and past week use hourly EIA-930 operations. Past year and all time use daily EIA-930 operations from 2019 for their equation, demand and net-flow graphs. Their generation-mix sections use monthly EIA-923 generation data, with the all-time mix beginning in 2001, so the two sections have different coverage. Positive cross-border values mean net imports and negative values mean net exports. Read About the data for coverage and lag details.
About the data
This is a best-effort public view of EIA electricity data, not a real-time operational dashboard, live grid telemetry, or a complete national accounting of electricity flows.
The past-day and past-week views align EIA-930 US48 demand, net generation, and total net interchange hour by hour before averaging the selected period. EIA records positive interchange as an outflow and negative interchange as an inflow; this site reverses that sign so positive cross-border flow means net imports and negative flow means net exports.
The headline cross-border value is read directly from EIA's US48 total-net-interchange field; this site does not calculate it by subtracting generation from demand. Under EIA's sign convention, demand is normally derived as net generation minus total net interchange—equivalent here to net generation plus net imports. Preliminary reports, revisions, missing values, and aggregation procedures mean the displayed figures may not reconcile exactly.
The aligned generation and total-interchange data normally arrive about one day after the reporting hour. Checked direct-pair interchange with Canada and Mexico normally arrives about two days after operation. When a complete common hour exists, the current headline and country card use it; otherwise the headline falls back to the latest complete national balance and the country rows retain their own timestamp. Times on this page describe the data, not when the page was refreshed.
The EIA-930 data used here cover the Lower 48 states and are supplied by balancing authorities. They do not provide a complete picture of every US electric system, and reported generation can exclude distributed resources, including rooftop solar, or resources that a balancing authority does not directly monitor.
The past-year and all-time demand, net-generation, and net-flow figures use the EIA-930 daily US48 series, which begins on 1 January 2019. Daily energy is converted to average power, and the site displays how many reporting days are present; missing days are omitted rather than estimated. A fixed-offset Arizona reporting day is used to avoid daylight-saving days of unequal length. This only sets the daily aggregation boundary.
The past-year and all-time generation pies, source tables, and generation graphs use monthly EIA-923 US generation data. The past year means the latest 12 published months, while all time begins with the available series in 2001. EIA-923 is published several months in arrears. These generation-mix sections therefore cover different dates from the EIA-930 operational equation, demand graph, and net-flow graph, and should not be read as one perfectly aligned energy balance.
Canada and Mexico are the foreign-country aggregates available for the Lower 48 border. Their rows come from EIA direct-interchange reports and are never invented or forced to equal the national figure. For a timestamp-aligned card, the US48 total is EIA’s separately reported total net interchange, and the reporting / reconciliation row is simply that total minus the available country rows; it is not an estimate for another country. Different submissions, anomaly handling, revisions, missing reports, and accounting discrepancies can create this difference.
Fuel types are grouped for display. Geothermal and any unmapped fuel types are included in Other; percentages are shares of the generation displayed here, not necessarily shares of all electricity produced or consumed. Negative generation values are set to zero before display because they can occur as source-data accounting artefacts.
Storage charging and discharge, wholesale prices, and carbon-intensity or emissions figures are not currently modelled. Missing values and unavailable series are not estimates of zero.
Values may change as the EIA revises data, corrects reporting issues, updates respondent coverage, or categorises fuel types differently over time. Use official grid-operator and EIA data for operational, safety-critical, or market decisions.
