Lowestoft, UK (17 June 2025) – TGS, the leading global provider of energy data and intelligence, signals a turning point for offshore wind in its latest quarterly 4C Offshore Global Market Overview Report, as leading European markets revisit subsidy models and a wave of new countries prepare to enter the sector.
Published exclusively for 4C Offshore subscribers, the Q2 2025 report offers a detailed update on global progress, setbacks and strategic recalibrations across more than 30 markets. The data show an industry at a key moment, as legacy markets grapple with policy and cost realities, emerging players compete for investor attention and companies reframe their strategies.
The report notes that key European markets, including Denmark, Germany and the Netherlands, are moving away from zero-subsidy models toward more bankable contracts for difference. The shift reflects pressure to balance investor certainty with public value, especially for projects previously approved under less sustainable financial frameworks.
At the same time, the report highlights growing momentum in new markets. Spain, Italy, Portugal, Brazil, the Philippines, Australia, New Zealand and Canada are each progressing toward first-of-a-kind auctions in 2025. With competition for capital and development partners intensifying, the report assesses each market’s outlook based on current economic and policy conditions.
In the first half of 2025, 5 gigawatts of offshore wind reached final investment decision, 12.1 GW entered construction and 3.1 GW achieved commercial operation, signs of ongoing activity despite continued market pressure.
Still, the report marks the third consecutive downgrade to Europe’s forecast, as shrinking timelines to 2030 dampen expectations. While long-term goals remain intact, achieving near-term capacity targets will require policy reform and stronger investor alignment.
To support decision-making in this shifting environment, 4C Offshore has launched Auction Explorer, a new tool cataloging the structure, criteria and outcomes of more than 200 offshore wind auctions across 28 markets. The database provides insights into auction status, scope, evaluation methods and key milestones, helping stakeholders assess performance and prepare for future rounds.
Will Ashby, Executive Vice President of New Energy Solutions at TGS, said: “The global offshore wind sector is at an inflection point. Understanding where, how and why the landscape is shifting is critical. The 4C Offshore Market Overview Report delivers the market intelligence needed to make informed, strategic decisions in a highly competitive environment.”
