Wind Meteorological (Met) Mast Installation in the Philippines

  1. Overview of Wind Meteorological Mast Installation

A Wind Meteorological Mast (Met Mast) is a tall structure equipped with instruments to measure and collect wind data. It serves as a critical component for assessing wind energy potential for utility-scale or small-scale wind projects. In the Philippines, where renewable energy is key to sustainable development, a thorough understanding of the principles, guidelines, and requirements is essential for successful installation.

  1. Purpose of Met Mast Installation

  • Wind Resource Assessment: Collect wind speed, direction, temperature, and pressure over a certain period (usually 1–2 years) to determine the feasibility of wind power projects.
  • Energy Yield Estimation: Analyze collected data to estimate the annual energy production (AEP) of a wind farm.
  • Site Suitability Analysis: Evaluate whether the location meets specific criteria for wind turbine placement.

  1. Key Principles of Met Mast Installation

3.1 Site Selection

  • Wind Potential: Choose sites with good wind flow, typically in elevated areas, ridgelines, coastal regions, or wind corridors.
  • Topography: Avoid obstacles (e.g., trees, hills, buildings) that may affect wind flow or create turbulence.
  • Accessibility: Ensure access for equipment, materials, and crew during installation and maintenance.
  • Grid Connectivity: Consider proximity to the power grid for eventual turbine connection.
  • Permitting: Secure all necessary permits in compliance with national and local regulations.

3.2 Design and Height

  • Height: The mast height typically ranges between 60m to 120m, depending on turbine hub height and project requirements. A taller mast ensures accurate wind data at future hub levels.
  • Measurement Levels: Install instruments at multiple levels (e.g., 60m, 80m, 120m) to capture wind shear and variations.
  • Design: Use lattice-type or tubular masts with guy wires for stability.

3.3 Instruments and Sensors

The Met Mast is equipped with the following instruments:

  • Anemometers: Measure wind speed at different heights.
  • Wind Vanes: Measure wind direction.
  • Temperature Sensors: Measure ambient temperature.
  • Barometers: Measure atmospheric pressure.
  • Data Loggers: Collect, store, and transmit wind data.
  • Solar Radiation Sensors (optional): For projects integrating solar and wind.

3.4 Structural Stability

  • Guy Wires: Properly tension guy wires to stabilize the mast against wind loads.
  • Foundation Design: Install secure concrete or steel foundations based on soil conditions.
  • Wind Loading Calculations: Follow structural design standards for wind resistance (refer to local building codes like the National Structural Code of the Philippines (NSCP)).

  1. Philippine Context: Regulatory Framework and Compliance

4.1 Legal and Regulatory Framework

In the Philippines, wind energy development is governed by several laws and guidelines:

  • Renewable Energy Act of 2008 (RA 9513): Promotes and incentivizes renewable energy projects.
  • Philippine Grid Code: Ensures compliance with grid interconnection standards.
  • DENR Environmental Impact Assessment (EIA): Required for large-scale wind projects.
  • Local Government Units (LGU) Permits: Securing clearances from barangay, municipal, or provincial levels.

4.2 Site Permitting and Documentation

  • Secure the following permits before installation:
  1. Landowner agreements or right-of-way permits.
  2. DENR clearance (Environmental Compliance Certificate, if required).
  3. Barangay and LGU permits.
  4. Safety and structural design certifications.

  5. Installation Process

 

  1. Pre-Installation Planning
  • Conduct a feasibility study and detailed site assessment.
  • Secure permits and approvals.
  • Identify equipment, mast design, and instrument specifications.
  1. Site Preparation
  • Clear and level the site.
  • Mark foundation locations for mast legs and guy wire anchors.
  • Transport materials and instruments to the site.
  1. Foundation Installation
  • Build concrete or steel anchors for the mast and guy wires.
  • Allow sufficient curing time for concrete foundations.
  1. Met Mast Assembly and Erection
  • Assemble the mast in sections on the ground.
  • Use cranes, winches, or pulley systems to raise the mast.
  • Secure guy wires at pre-determined anchor points and tension accordingly.
  1. Instrument Installation and Calibration
  • Install anemometers, wind vanes, and sensors at designated heights.
  • Calibrate all instruments as per international standards (IEC 61400-12).
  1. Testing and Commissioning
  • Verify sensor data transmission through data loggers.
  • Perform a stability and safety check of the mast structure.
  1. Operation and Monitoring
  • Continuous monitoring of wind data and equipment performance.
  • Routine maintenance of instruments, guy wires, and structural components.

  1. Best Practices

  • Compliance with International Standards: Follow the IEC 61400-12 standard for wind measurement and Met Mast installation.
  • Safety First: Use proper safety gear and follow safety protocols during installation (e.g., harnesses, helmets).
  • Data Quality Assurance: Regularly calibrate sensors to maintain data accuracy.
  • Redundancy: Install duplicate sensors at critical heights to avoid data loss.
