North America Electricity Flows Map
Between 28 September 2026 and 27 October 2026 the largest net flow of electricity between two US grid operators was 2.34 TWh, from SRP into AZPS. The Lower 48 states imported a net 2.19 TWh from Canada. The map shows the net flow on the 45 largest of 157 borders between balancing authorities, summed over 30 complete days: a wider line is a larger net flow and the arrowhead points to the operator that received it. These are EIA interchange figures for that window, not live readings.

The map draws the 45 largest of 157 borders by net flow over the 30 days 28 September to 27 October 2026, from 227 GWh (thinnest) to 2.34 TWh (widest). The arrowhead points to the operator that received the net flow. Node positions are approximate, and lines join those points: they are not cable routes.

Interchange between each pair of balancing authorities, summed over 30 complete days (28 September to 27 October 2026). Net is the average of the two operators' reports; average net power is the net divided by the 720 hours in the window. Each report is signed from the first operator's side: positive means energy left the first named operator for the second. "First operator" follows the order of the border name. A border with only one report is a Canadian or Mexican operator, or a US operator that does not report the other side.

Built from the averaged border figures above. A positive net means the operator sent out more than it received across its borders with the operators listed in the window; a negative net means it was a net importer. Interchange with operators not covered by EIA is not counted, and flows within an operator's own area are not counted.
Key Facts
- EIA balancing authorities reported interchange on 157 borders between 70 operators in the 30 days 28 September to 27 October 2026.
- The largest net flow in the 30 days to 27 October 2026 was 2.34 TWh from SRP to AZPS, an average of 3,254 MW.
- Salt River Project Agricultural Improvement and Power District was the largest net exporter in the 30 days to 27 October 2026, at 2.49 TWh.
- California Independent System Operator was the largest net importer in the 30 days to 27 October 2026, at 2.82 TWh.
- The Lower 48 states imported a net 2.19 TWh from Canada in the 30 days to 27 October 2026.
- The Lower 48 states exported a net 61.4 GWh to Mexico in the 30 days to 27 October 2026.
- Both operators reported 143 of the borders and agreed on the direction of 141 of them in the 30 days to 27 October 2026.
Reading the Map
- Sign convention. EIA reports interchange from each balancing authority's own side: a positive figure means energy left that operator for its neighbour, a negative figure means it arrived. The map shows the direction of the net flow, from the operator that sent it to the one that received it, and the table gives the signed reports.
- Two reports, one border. Both operators on a border report it, and their meters rarely match exactly. The net flow on the map and in the tables is the average of the two reports; each report is in the border table. Both operators reported 143 borders and agreed on the direction of 141.
- Window totals. Each figure is a sum over 30 complete days, 28 September to 27 October 2026. The export holds one total per border, so the map does not show a single day or an hour by hour picture.
- Net, not gross. Power can cross a border in both directions within the window. The map shows the difference, so a busy border with balanced traffic can look quiet.
- Balancing authorities. The 60 operators that report interchange to EIA are electric system operators, not states or countries, and vary from ERCOT and PJM to a single city utility. Nodes sit at hand placed approximate centres, and lines join those points: they show which operators are linked, not where lines run.
- Canada and Mexico. Canadian and Mexican operators are shown as nodes on their side of the border, from the US side's reports only. The Canada and Mexico totals for the Lower 48 come from EIA's own aggregate.
- Map and tables. To keep the map readable it draws the 45 largest borders. Every border, including the smallest, is in the table, and so is each operator's net position.
