Ranking of groups

Largest grid connection holders in the world, by group

The 100 largest of 2,746 grid connection holders in the world, each company counted under its ultimate parent and ranked by the capacity of the grid connections the group's companies own, operate or hold. Windward Enterprises Limited leads with 24,000 MW across 7 grid connections, held by 7 of its companies, ahead of Orrön Energy Greenfield Ab (23,200 MW) and RWE Aktiengesellschaft (19,229 MW).

A group is a parent company in the data and every subsidiary under it (GLEIF, Wikidata and the UK register of people with significant control); a company with no parent in the data is a group of its own. Each grid connection counts once per group, in whole, or by the group's share where a source records one. A grid connection with owners or operators in two groups counts in both, so the sizes do not add up to the world's total.
