TSMC Signs 30-Year Wind Power Deal as Taiwan's Energy Crunch Deepens

Taiwan Semiconductor Manufacturing Company has signed a 30-year corporate power purchase agreement with Northland Power for the entire output of the 1.02-gigawatt Hai Long offshore wind project, a move that underscores the scale of the island's energy dilemma as its largest electricity consumer races to decarbonize.

The Details

The deal grants TSMC roughly 1.02 gigawatts of capacity from the Hai Long wind complex, located off Changhua County on Taiwan's west coast. The project is split across three offshore sites with capacities of 294 megawatts (Hai Long 2A), 224 megawatts (Hai Long 2B), and 504 megawatts (Hai Long 3). Power from the wind farms began flowing into Taiwan's grid earlier in 2025, with full commercial operation scheduled for 2027. Corporate power purchase agreements of this length are uncommon, but the 30-year term reflects TSMC's need for consistent, long-term renewable supply as its electricity consumption continues to climb. The company has previously struck similar wind deals with Orsted for 920 megawatts and with WPD for over a gigawatt. Northland Power, the project developer, announced the agreement in an official press release.

Context

TSMC's energy appetite has grown so large that it now represents a structural challenge for Taiwan's national grid. In 2023, the chipmaker's electricity consumption accounted for nearly 10 percent of the island's total, according to data cited in International Energy Agency reporting. S&P Global estimates project that share could climb to nearly 24 percent by 2030 if TSMC continues expanding advanced semiconductor manufacturing to meet global artificial intelligence demand. S&P Global data also show the company's electricity consumption more than doubled from roughly 110 gigawatts in 2016 to approximately 250 gigawatts in 2023. Taiwan's broader energy situation makes that growth particularly difficult to absorb. The island relies on imported fossil fuels for approximately 97 percent of its overall energy supply, and natural gas-fired plants generate about half of its electricity. Compounding the vulnerability, Taiwan typically maintains only 11 to 14 days of natural gas reserves. A recent disruption in the Middle East has intensified those concerns. Iranian strikes on Qatar in March 2026 caused QatarEnergy to declare force majeure on some liquefied natural gas contracts, removing 17 percent of Qatar's total LNG capacity from the market for an estimated three to five years. Taiwan sourced roughly 10.7 billion cubic meters of LNG from Qatar in 2025, making the island a significant destination for Qatari exports. In response, Taiwan has secured alternative LNG deliveries from Australia and the United States, and the Vice Minister of Economic Affairs stated on May 6, 2026 that the government had secured enough oil and gas supplies to operate normally through August, and possibly September. Taiwan's administration under President Lai Ching-te has accelerated efforts to diversify beyond fossil fuels, including restarting nuclear discussions and expanding renewable projects. The government has a stated plan to make 15 gigawatts of offshore wind capacity available to developers by 2035.

What's Next

TSMC has set a target for renewable energy to meet 60 percent of its global operations' needs by 2030, and 100 percent by 2040. Whether that timeline is achievable depends in part on how quickly Taiwan can bring additional offshore and onshore renewable capacity online, and whether the island can reduce its heavy dependence on fossil fuel imports. The Hai Long project, scheduled to reach full output in 2027, will be one of the largest single sources of renewable power for TSMC's domestic fabs. Its performance and reliability will be closely watched by both energy analysts and chip industry observers. Taiwan will also need to assess whether its current natural gas storage levels and alternative import routes are sufficient if Middle East disruptions persist. The Vice Minister's public reassurance provides a near-term timeline, but beyond September the island's energy security outlook remains tied to shipping lanes it does not control.
