Research methodology

Every figure on this page comes from the research framework that we apply to all of the markets we cover. The 2025 base for the electricity transmission market is built from the volume sold and the price that buyers pay, and is cross-checked against the size of the wider industry the market belongs to. Where a market can be sized in more than one way, the routes are compared before a figure is set.

The forecast runs year by year from the 2025 base to 2036. Growth in each year reflects demand from the industries that buy the product, adoption of new technology, pricing, regulation and replacement cycles. Volume and price are modelled together, so revenue in each year equals volume multiplied by average price. The 2026 to 2036 compound annual growth rate of 6.0% is calculated from the resulting values.

The market is divided by voltage, by operator, by line type, by revenue source, by activity. The 25 largest countries are ranked by revenue earned from sales to buyers in each country, not by where the product is made. Segment values and country values add up to the market total in every year, and every report is checked for consistency before it is published.

Companies are placed in three groups: global leaders, regional and specialist players, and emerging and niche players. The groups describe how companies compete in the market. They are not a ranking and they are not market shares.

Our analysts also carry out primary research. Customized reports add interviews with key opinion leaders, such as senior executives, technical specialists and buyers, to test the assumptions behind the numbers for the question being asked.
