The Philippines’ growing energy demand calls for sustainable solutions that reduce environmental impact while supporting economic progress. ACEN has emerged as a key player in this transition, harnessing the country’s abundant wind resources to fuel clean, renewable power.
This article explores the types of wind energy and turbines, showcases ACEN’s significant wind projects across the globe, and highlights how these efforts contribute to the broader energy transition toward Net Zero emissions.
Types of wind energy and wind turbines
What are the types of wind energy? Wind energy is primarily classified by its location and the type of turbines used to capture it. 1 Understanding these distinctions helps clarify how wind power is harnessed efficiently and innovatively.
Onshore and offshore wind energy
- Onshore wind energy: These wind farms are located on land, typically on ridges, open plains, or hilltops where wind speeds are favorable and consistent. Advantages of onshore wind include relatively easier installation and maintenance. However, they may face challenges such as land use conflicts and local noise concerns.
- Offshore wind energy: Offshore farms are built in large bodies of water, such as seas or oceans. These locations benefit from stronger, steadier winds due to fewer surface obstructions. Offshore turbines are generally larger, with longer blades and taller towers, enabling higher energy output. Although installation and maintenance costs are higher, offshore wind plays a vital role in expanding renewable energy capacity, particularly in countries with limited suitable onshore sites.
Different types of wind turbines
How does wind energy work? Wind turbines transform kinetic wind energy into electrical power through mechanical means. There are two main types: 2
- Horizontal-axis wind turbines (HAWTs): These are the most common, featuring blades that rotate around a horizontal shaft like airplane propellers. Their design typically includes three blades mounted on a tall tower to reach optimal wind speeds. HAWTs rotate to face the wind, requiring mechanisms to optimize energy capture. Their efficiency and scalability make them the backbone of most large-scale wind farms.
- Vertical-axis wind turbines (VAWTs): VAWTs rotate around a vertical shaft, allowing them to capture wind from any direction without repositioning. They often resemble an eggbeater shape. While useful in specific urban or turbulent wind environments, VAWTs generally have lower efficiency and are less common than HAWTs.
By leveraging these designs, both onshore and offshore turbines optimize wind resources, reduce emissions, and support energy transition goals.
ACEN wind energy projects around the world
ACEN leads the development of different types of wind energy in the Philippines and across the Asia Pacific with a diversified portfolio of projects:
- Pagudpud Wind (160 MW) in Ilocos Norte is the Philippines’ largest wind farm, harnessing the strong monsoon winds prevalent in the northern region.
- NorthWind (52 MW), Capa Wind (70 MW), and North Luzon Renewables (81 MW) in Ilocos Norte support local and national energy grids with clean power.
- Guimaras Wind (54 MW) in the Visayas region takes advantage of reliable coastal and ridgeline winds.
Internationally, ACEN operates projects that strengthen its global footprint in renewables, such as:
- Vietnam: Lac Hoa and Hoa Dong Wind (60 MW); Mui Ne Wind (84 MW); Ninh Thuan Wind (88 MW); Quang Binh Wind (252 MW). Leveraging strong local partnerships, ACEN continues to harness the country’s vast wind energy potential to bolster its shift to a sustainable future.
- Lao PDR: Monsoon Wind (600 MW). The first cross-border renewable energy project in Southeast Asia that will deliver clean electricity to neighboring Vietnam. It is also the largest wind facility in the region and the first wind farm in Lao PDR.
- USA: Chestnut Flats Wind (38 MW); Stockyard Wind (129 MW). Through a joint venture with PivotGen and UPC Solar & Wind Investments, ACEN is extending old wind farms’ productive life by implementing robust preventive maintenance and repowering initiatives.
ACEN’s wind projects reduce carbon emissions, promote local job creation, and contribute to energy security in all their locations. Their mix of onshore and offshore developments exemplifies innovative approaches tailored for diverse environments.
ACEN’s commitment to the energy transition
ACEN recognizes that the different types of wind energy are not isolated solutions but a part of a comprehensive approach to energy transition. ACEN already operates at 100% renewable energy capacity and is the first energy company in Southeast Asia to publish a detailed Net Zero roadmap.
As a wind power company, ACEN’s energy assets complement other renewables like solar and geothermal, collectively stabilizing grids and advancing national climate commitments. Beyond power generation, ACEN invests in workforce development, local infrastructure, and community partnerships to ensure that the benefits of renewable energy are inclusive and far-reaching. Their proactive role accelerates the Philippines’ sustainable growth and aligns with global efforts to limit climate change impacts.
Building a sustainable tomorrow with wind energy
ACEN’s wind energy projects demonstrate the power of combining innovation, strategic planning, and environmental responsibility. By harnessing abundant types of wind energy, ACEN not only generates clean electricity but also foåsters economic development and climate resilience.
As the Philippines and the broader Asia Pacific region move toward ambitious clean energy goals, ACEN’s leadership highlights how renewable energy sources in the Philippines can be scaled effectively. At the same time, renewable energy can empower communities and secure their energy independence. The future of sustainable energy is wind-powered, and ACEN is at the forefront of this transformative journey.
