PetroChina Offshore Wind Initiatives for 2025: Key Projects, Strategies and Partnerships

PetroChina’s Offshore Wind Gambit: From Pilot Projects to a Strategic Pillar

As Asia’s largest oil and gas producer, PetroChina is navigating one of the most significant transformations in its history. Faced with global pressure for decarbonization and China’s ambitious carbon neutrality goals, the state-owned giant is making a calculated and increasingly assertive pivot into clean energy. While its portfolio is diversifying across solar, hydrogen, and natural gas, its foray into offshore wind reveals a compelling strategy of leveraging legacy strengths to build a new energy future. This analysis examines PetroChina’s journey in offshore wind, tracing its evolution from early-stage pilots to an integrated component of its long-term vision.

From Nascent Pilots to a Strategic Imperative

PetroChina’s engagement with offshore wind has evolved from cautious exploration to a declared strategic priority. Between 2021 and 2024, the company’s approach was characterized by building foundational capabilities and testing the technological and commercial waters. This period saw the launch of its first floating offshore wind turbine in July 2022 and the completion of the “Haiyou Guanlan” deep-sea floating wind power platform in 2023. These projects served as crucial pilot programs, allowing PetroChina to de-risk a new technology domain. Concurrently, the company signaled its commercial ambition by partnering with State Power Investment Corporation Limited in 2022 to acquire a 900,000 kW offshore wind project in Guangxi. This dual approach—developing proprietary technology while partnering for scale—demonstrates a pattern of deliberate, risk-managed entry into the renewables market.

The period from January 2025 to today marks a distinct inflection point. The narrative has shifted from experimentation to integration. The company now explicitly frames its offshore wind expansion as a way to “leverage its existing offshore engineering expertise,” a clear signal that it views its oil and gas heritage as a competitive advantage, not a liability, in the renewables race. While no new standalone offshore wind partnerships were detailed in 2025, the operational results speak volumes: wind and solar power generation soared by 94.6% in the first quarter of 2025. This surge indicates that earlier projects are now contributing meaningfully to the energy mix. The primary opportunity lies in translating its deep offshore experience into cost-effective and large-scale wind projects. However, a threat remains in its dual strategy, as demonstrated by the massive $9.56 billion investment in the Dalian refinery revamp, which could divert capital and focus away from the clean energy transition.

From Domestic Proving Grounds to Global Energy Plays

PetroChina’s geographic strategy for offshore wind has been firmly rooted in its domestic market, which serves as a large-scale laboratory. Between 2021 and 2024, nearly all significant clean energy milestones occurred within China. This includes the Guangxi offshore wind project, the Haiyou Guanlan floating platform off the Chinese coast, and the renewables-powered petrochemical complex in Xinjiang. This domestic focus allowed the company to align with national energy security mandates, build a local supply chain, and develop operational expertise in a controlled environment. The few international ventures from this period, such as the offshore oil exploration in Suriname and the gas project in Australia, remained squarely in the hydrocarbon space.

From 2025, the geographic landscape has begun to shift, not through new wind projects abroad, but through the operational start of major international energy transition assets. The first LNG cargo from the LNG Canada project in July 2025 is a landmark event. While a Canadian project, PetroChina’s 15% stake makes it a key international pillar of its strategy to secure transition fuels. This suggests a bifurcated geographic strategy: China remains the incubator for scaling up newer technologies like offshore wind, while international partnerships are focused on securing resources like LNG that are already commercially mainstream and critical for balancing a renewables-heavy grid. The risk is a potential technology lag if its international clean tech investments do not keep pace with its domestic ambitions.

Crossing the Chasm: From Floating Demos to an Integrated Energy System

The technological maturity of PetroChina’s wind portfolio has advanced rapidly. The 2021-2024 period was defined by moving from demonstration to early commercialization. The 2022 launch of its first floating wind turbine was a pure technology demonstration. The 2023 completion of the Haiyou Guanlan deep-sea platform represented a more advanced pilot, pushing the envelope on deep-water applications. The true commercial step-up during this time was the partnership to acquire the 900,000 kW project in Guangxi, a move that leapfrogged the lengthy process of organic development and immediately established a commercial-scale presence.

In 2025, the focus has clearly shifted to scaling and integration. The technology is no longer just being tested; it is an operational and growing part of the business. The 94.6% year-over-year increase in wind and solar generation in Q1 2025 is the strongest validation point that PetroChina is now a significant renewable power producer. Furthermore, the strategic acquisition of CNPC’s Electric Energy unit in August 2025 signals a move toward system-level maturity. The goal is no longer simply to build turbines but to “enhance synergy between renewable energy and power segments.” This indicates that offshore wind technology is now considered mature enough to be integrated into a complex energy system alongside natural gas, power trading, and industrial demand, marking its transition from a niche pilot to a core component of the company’s future.

What to Watch: The Integration of Wind, Power, and Gas

The most recent data signals that PetroChina’s clean energy strategy is entering a more sophisticated phase focused on integration. The era of standalone pilot projects is giving way to the development of a complex, interconnected energy system. Market actors should pay close attention to the operational integration of the newly acquired CNPC Electric Energy unit. This move is the clearest signal yet of PetroChina’s ambition to become a true integrated energy company, managing generation, transmission, and sales.

Looking ahead, we should expect to see projects that explicitly link its different business lines, such as offshore wind farms built to directly power its offshore oil and gas platforms or new petrochemical facilities. This would be the ultimate validation of its synergy strategy. The concurrent, massive investments in both offshore wind and natural gas storage are not contradictory; they are two sides of the same coin. Gas provides the firm, dispatchable power needed to balance the intermittency of wind. The next key signal will be how PetroChina operationally and financially connects these two investment streams to optimize the grid. The focus is no longer just on megawatts of capacity but on creating a resilient and profitable low-carbon energy system.
