Price Gaps Between Neighbouring Electricity Zones, to 2026-11-13 (13 November 2026)

Across 78 pairs of neighbouring European bidding zones, the widest average day-ahead price gap was EUR 150.43/MWh between Sweden North-Central (SE2) and Sweden South-Central (SE3), and prices were identical in 15% of all compared hours, over 5 to 13 November 2026.

Day-ahead wholesale prices from ENTSO-E in EUR/MWh, compared hour by hour for 78 pairs of zones that share a border. The window is short, 5 to 13 November 2026, and a gap here is an indicator of a constrained interconnector, not proof of congestion.

Key Facts

  • Across 78 pairs of neighbouring European bidding zones, the widest average day-ahead price gap was EUR 150.43/MWh between Sweden North-Central (SE2) and Sweden South-Central (SE3), and prices were identical in 15% of all compared hours, over 5 to 13 November 2026.
  • Sweden North-Central (SE2) and Sweden South-Central (SE3) had the widest average gap, EUR 150.43/MWh over 199 compared hours, with Sweden North-Central (SE2) cheaper in 100% of hours.
  • Italy Centre-North and Italy North had the narrowest average gap, EUR 0.00/MWh, with identical prices in 100% of 199 compared hours.
  • Norway Central (NO3) and Norway North (NO4) had the most hours more than EUR 20.00/MWh apart, 100% of 199 compared hours. This is an indicator of constrained interconnectors, not proof of congestion.

The widest gap was Sweden North-Central (SE2) and Sweden South-Central (SE3), EUR 150.43/MWh on average over 199 compared hours. Bars show the average of the absolute difference between the two zones' hourly prices, so a pair that swaps which side is dearer still registers its full gap.

Identical hours are hours where the two zones' hourly average prices match to the cent. Usually cheaper is the zone with the lower price in more hours, with the share of all compared hours after the name; the rest are hours where the other side was cheaper or the prices were identical. Pairs that share the same price in at least 99.5% of hours read Same price.

(ENTSO-E Terms of Use plus CC BY 4.0 for listed data items) Data as of 2026-11-13. Gaps are computed by World Power Monitor from ENTSO-E day-ahead market intervals. Neighbours come from the ENTSO-E physical cross-border flows file.

How These Gaps Are Measured, and What They Do Not Show

  • Neighbours: a pair counts when ENTSO-E's physical cross-border flows file (13 October to 11 November 2026, 88 borders) records flow across the border and both zones have day-ahead prices in euros. The list is derived from that file, so a border with no recorded flow, or with a zone that has no prices, is not here.
  • Hours: each zone's market intervals (15 or 60 minutes) are averaged to the clock hour, and only hours where both zones have a full hour of prices are compared. A pair needs at least 48 such hours. The window is 5 to 13 November 2026, so these are at most 199 hours of prices, not a season or a year, and the newest hours can be a delivery day whose prices were published the day before.
  • Identical prices are what a fully converged market coupling looks like, but a pair can also match by coincidence, and zones at the edge of the coupled area can differ for reasons other than a congested line.
  • A share of hours more than EUR 20.00/MWh apart is a rough indicator that something limited trade between the two zones, for example a full interconnector. It is not proof of congestion: this page uses no capacity, flow limit or congestion rent data, and a wide gap can also come from zones being outside the same coupled market.
  • Prices are day-ahead wholesale prices in EUR, not household prices and not converted. Zones priced in another currency are left out.

Price Gaps Between Zones: Questions and Answers

Why do neighbouring countries have different electricity prices?

Day-ahead prices are set separately for each bidding zone. Neighbouring zones share a price when the power lines between them have room to carry the trade the market wants, and split when they do not. In the window analysed, 5 to 13 November 2026, Sweden North-Central (SE2) and Sweden South-Central (SE3) were EUR 150.43/MWh apart on average, the widest of 78 pairs.

What does it mean when two zones have an identical price?

It means the two zones cleared at the same price in that hour, which happens when the market coupling algorithm did not need to limit trade between them. This page counts hours where the two hourly averages match to the cent.

Does a price gap prove an interconnector is congested?

No. A gap above EUR 20.00/MWh in many hours, as for Norway Central (NO3) and Norway North (NO4) at 100% of hours, is consistent with a constrained line, but day-ahead prices also differ where the zones are not fully coupled, and this page does not use capacity or congestion data.

How are neighbouring zones chosen?

A pair counts as neighbouring when ENTSO-E reports measured physical flows across the border between the two zones in the cross-border flows data, and both zones have day-ahead prices in euros. Pairs without both prices are left out.

Is this the price I pay or the price traders get?

Neither exactly. These are day-ahead wholesale prices, the market result for each hour of the following day. Household bills add network charges, taxes and supplier margins, and traders also use later markets.
