Global Renewable Power Capacity Expected To More Than Double By 2030

Solar photovoltaic technology will drive nearly 80% of renewable capacity growth despite supply chain and grid integration challenges, with corporate deals expected to double their market share by 2030.

  • Tuesday, the International Energy Agency projected global renewable power capacity will more than double by 2030, increasing by about 4,600 GW with nearly 60 percent from China.
  • Following policy shifts, the IEA slightly cut its growth outlook due to the U.S. tax-incentive phase-out and China’s move from fixed tariffs to auctions.
  • Market mechanisms like corporate PPAs will supply 30% of global renewable additions to 2030, doubling last year’s share, as 750GW is installed this year but 1,700GW waits connection.
  • IEA calls for accelerated grid and storage investment as rapid renewable growth causes curtailments and negative price events, straining electricity markets and infrastructure.
  • Looking ahead, supply and sectoral risks could blunt parts of the expansion as supply chains for solar cells and rare-earth materials remain over 90% concentrated in China, while offshore wind growth is 25% lower than last year.
