As Macau continues its push toward renewable energy adoption, the Feed-in Tariff (FiT) program offered by Companhia de Electricidade de Macau (CEM) provides a great opportunity for businesses and homeowners to benefit from solar energy generation. If you’re considering installing a photovoltaic (PV) system and connecting it to Macau’s power grid, understanding the application process is essential. Here’s a clear, step-by-step guide to help you navigate the process.
Feed-in Tariff Rates
Grade Installed Capacity of Solar PV System Current Feed-in Tariff (MOP/kWh)
I Below 10 kW / 3.7
II 10 to 100 kW/ 3.4
III Over 100 to 500 kW/ 3.0
IV Over 500 kW/ 2.8
Step 1: Assess the Installation Feasibility
Before applying, you must ensure your site is suitable for PV installation. Key factors to consider include:
• Ownership and permissions: Verify you have the legal right to install the system at the chosen location.
• Space requirements: For rooftop installations, at least half of the area should remain unobstructed for fire escape purposes.
• Sunlight availability: The location must receive adequate sunlight without obstruction from nearby buildings.
• Regulatory considerations: If the building has architectural significance or is in a classified real estate buffer zone, compliance with Macau’s Cultural Heritage Protection Law is required.
Step 2: System Design and Engineering
Once feasibility is confirmed, the PV system must be designed by a qualified professional registered with the DSSCU (Macau’s regulatory authority). The design must comply with local regulations, including:
• Grid-connection standards and safety requirements.
• Anti-backflow device requirements if the system connects to an internal electrical network rather than directly to the grid.
Step 3: Apply for a Work License
Before installation can begin, the project must be submitted to DSSCU for approval. Work can only commence after obtaining the necessary permit. However:
• For systems with a total capacity of up to 3 kWp, installation may proceed 30 days after submitting the project notification.
• If the building is under heritage protection, additional approvals from the Cultural Affairs Bureau will be required before DSSCU grants final approval.
Step 4: Installation and Construction
Once approvals are secured, installation can begin. During this phase, it is crucial to:
• Follow construction safety protocols.
• Adhere to Macau’s environmental noise control regulations.
Step 5: System Testing and Compliance Check
After installation, the system undergoes thorough testing by the responsible engineer. The evaluation covers:
• Electrical quality compliance, including harmonics and waveform distortion.
• Warning signs and safety protection measures.
• Operational performance of the inverters.
The engineer must issue a declaration of responsibility confirming compliance with all applicable regulations.
Step 6: Final Approval from DSSCU
Once installation and testing are complete, an acceptance request is submitted to DSSCU for final verification. This step ensures:
• The installation aligns with the originally approved design.
• Compliance with all local regulations is met.
For systems not connected to the public grid, operation may begin immediately after DSSCU’s approval.
Step 7: Grid Interconnection Application with CEM
After obtaining DSSCU’s approval, the next step is to apply for interconnection with CEM. This requires submitting:
• System design specifications.
• Declaration of responsibility from the engineer.
• Test records proving compliance.
Once all documents are reviewed and approved, CEM will:
• Confirm the connection point.
• Install the appropriate meter.
• Finalize the interconnection contract.
Once the contract is signed, the PV system can begin exporting electricity to the grid.
Step 8: Ongoing Maintenance
After commissioning, regular maintenance ensures the system operates efficiently. Routine checks should include:
• Keeping PV panels clean.
• Ensuring all electrical connections remain secure.
• Monitoring inverter performance.
By following these steps, businesses and individuals in Macau can successfully participate in the Feed-in Tariff program, contributing to a greener, more sustainable energy future while benefiting from long-term cost savings.
