How electricity markets price power around the world

A global guide to nodal, zonal and single-price markets, including all 60 Lower 48 balancing authorities tracked by EIA.

New Zealand settles wholesale electricity at individual grid nodes. Across the Tasman Sea, Australia’s National Electricity Market sets five regional spot prices. Alberta clears one hourly pool price for the province. All three systems can face transmission bottlenecks. The rules determine how much of that geography appears in the price participants settle against.

How to read the prices#

A locational marginal price, or LMP, measures the cost of supplying one more megawatt-hour at a specific grid location. A zonal price applies across a defined area, with separate prices when the market’s rules split zones or account for constraints between them. A single system price applies across one market footprint for a delivery interval. Where utilities buy power through contracts or at regulated tariffs, there may be no centralized spot price. FERC energy markets guide · IEA electricity market design

A headline price can be an average or a financial reference. For the hour beginning at 3 p.m. Eastern on November 10, 2026, New York’s day-ahead load-zone price was $42.06/MWh on Long Island and $34.05/MWh in New York City. Most of the $8.01/MWh gap came from congestion. Both are zonal aggregates in a nodal market. The Nordic system price serves a different purpose. It is a financial reference calculated without internal Nordic transmission limits, while the physical day-ahead market settles at bidding-zone prices.

Wholesale pricing by market and grid#

The U.S. tables cover all 60 active balancing authorities in EIA’s Lower 48 reporting roster and cover Alaska’s Railbelt, Hawaii and the inhabited U.S. territories separately. The international tables compare national and regional markets across every inhabited continent, with examples of contract-based systems. Market rules and operating status are as of November 11, 2026. EIA reporting roster · World Bank power market structures by economy

What changes the price you settle at#

Ontario introduced day-ahead and real-time nodal pricing on May 1, 2025. Most wholesale load still settles against a province-wide price with an adjustment based on real-time outcomes. Alberta’s planned market redesign would introduce real-time LMPs and retain a province-wide price for most load. AESO targets the second quarter of 2028 for the cutover. IESO market pricing · AESO market design · AESO implementation schedule

A utility’s contract supply and its market trades can also have different prices. Bonneville sells federal power under rates and contracts and uses the Western Energy Imbalance Market to price participating real-time deviations at LMPs. The same distinction applies internationally. The Southern African Power Pool can clear different area prices for cross-border trades while domestic utilities continue to serve customers under national arrangements.

Scope and sources#

Demand measures electricity use across a grid or geography. Trading volumes are a separate measure. U.S. balancing-area figures sum adjusted hourly demand from EIA. Other figures use published system load, electricity supply within a geographic boundary, or national demand from Ember. Grouped totals can overlap with smaller systems, so the rows should be compared individually. EIA-930 data · Ember yearly electricity data · Statistics Canada annual electricity data

The tables compare how wholesale energy is priced and identify the applicable market or settlement stage. The Lower 48 rows follow current EIA-930 reporting boundaries. SPP East and SPP West are two balancing authorities in one organized energy market. International rows can cover several countries or pricing zones under one rule set. The world tables are a market reference and do not inventory every local utility or isolated system. Ask the Grid links indicate where the product has a corresponding public view or catalog.
