How EMA and SP Services Processes Work in Singapore Regarding Solar Energy: A Detailed Guide

Installing solar energy systems in Singapore involves a comprehensive process regulated by the Energy Market Authority (EMA) and facilitated by SP Services. Understanding the steps, rules, and regulations is essential for a smooth and compliant installation. This article written in early 2024 provides an in-depth look into the processes involved, helping you navigate the regulatory landscape effectively. We suggest to continue exploring the EMA and SP websites for updated information.  

Overview of EMA and SP Services

Energy Market Authority (EMA): The EMA is the statutory board under the Ministry of Trade and Industry responsible for ensuring a reliable and secure energy supply in Singapore. It regulates the electricity and gas industries and promotes the adoption of renewable energy sources, including solar energy.

SP Services: SP Services, a subsidiary of Singapore Power Group, is the market support services provider that handles the metering and billing of electricity, as well as facilitating the connection of solar energy systems to the grid.

The Energy Market Authority (EMA) and SP Services play crucial roles in Singapore's solar energy landscape. Here's a breakdown of their processes:

EMA's Role

• Policy Framework: The EMA sets the regulatory framework for Singapore's electricity market, including policies related to solar energy.  
• Net Energy Rebate (NER) Scheme: The EMA administers the NER scheme, which provides financial incentives for homeowners and businesses that install solar panels and export excess electricity to the grid.
• Market Oversight: The EMA monitors the electricity market to ensure fair competition and consumer protection.  

SP Services' Role

• Metering and Grid Connection: SP Services is responsible for metering and connecting solar installations to the grid.
• Simplified Credit Treatment Scheme (SCT): SP Services facilitates the SCT for non-contestable consumers (SP customers) who wish to participate in the NER scheme.  
• Electricity Tariff: SP Services determines the electricity tariff for non-contestable consumers.

How the Processes Work Together

1. Homeowner or Business Owner: A homeowner or business owner decides to install solar panels.
2. Solar Installer: They engage a licensed solar installer to design and install the solar system.
3. Grid Connection: The installer applies to SP Services for grid connection.
4. NER Scheme Registration: If eligible, the homeowner or business owner can register for the NER scheme through SP Services.
5. Metering: SP Services installs a bi-directional meter to measure both electricity consumption and export.
6. NER Payments: Excess electricity exported to the grid is credited to the homeowner or business owner's account, based on the NER tariff.

Key Points to Remember:

• Contestable Consumers: Homeowners or businesses that purchase electricity from an independent retailer other than SP are considered contestable consumers. They have more options for electricity plans and may have different procedures for participating in the NER scheme.  
• Regulatory Compliance: Both EMA and SP Services ensure that solar installations comply with safety and technical standards.  
• Market Competition: The Open Electricity Market allows consumers to choose their electricity provider, which can lead to more competitive pricing and innovative offerings.  

By understanding the roles of EMA and SP Services, homeowners and businesses can navigate the process of installing solar panels and benefiting from the NER scheme in Singapore.

Step-by-Step Process for Solar Energy System Installation

1. Feasibility Study and Initial Planning

Step 1: Conduct a Feasibility Study

• Evaluate the potential for solar energy at your site, considering factors such as roof space, orientation, shading, and structural integrity.

• Engage a professional solar installer or consultant to conduct a detailed site assessment.

Step 2: Initial Planning

• Determine the size and capacity of the solar energy system based on your energy consumption and available roof space.

• Consult with a licensed electrical worker (LEW) to ensure compliance with technical and safety standards.

2. Application for Connection to the Grid

Step 3: Submit an Application to SP Services

• The LEW submits an application for the connection of the solar energy system to the grid through the SP Services Online Portal.

• Include detailed technical specifications, single-line diagrams, and relevant site information.

Step 4: Review and Approval by SP Services

• SP Services reviews the application to ensure it meets all technical requirements and safety standards.

• Once approved, SP Services issues an “In-Principle Approval” (IPA) for the connection.

3. Installation and Commissioning

Step 5: Installation of the Solar Energy System

• Engage a qualified solar installer to carry out the installation, ensuring adherence to the approved design and safety standards.

• The LEW supervises the installation to ensure compliance with regulatory requirements.

Step 6: Commissioning and Testing

• After installation, the LEW conducts comprehensive testing and commissioning of the solar energy system.

• Ensure that the system operates safely and efficiently before connecting it to the grid.

4. Inspection and Connection to the Grid

Step 7: Request for Inspection by SP Services

• Submit a request for inspection through the SP Services Online Portal.

• SP Services schedules an inspection to verify that the installation meets all regulatory and safety standards.

Step 8: SP Services Inspection

• An SP Services officer conducts an on-site inspection of the solar energy system.

• If the system passes the inspection, SP Services issues a “Final Approval” for grid connection.

Step 9: Connection to the Grid

• SP Services facilitates the connection of the solar energy system to the grid.

• Install a bi-directional meter to measure both the electricity consumed from the grid and the electricity exported to the grid.

5. Registration and Billing

Step 10: Registration with EMA

• Register the solar energy system with EMA through the Energy Market Authority’s Online Portal.

• Provide all required documentation, including the system’s technical specifications and installation details.

Step 11: Net Metering and Billing

• SP Services implements net metering, allowing you to receive credits for excess electricity exported to the grid.

• Monitor your electricity bills to track consumption and export data, ensuring accurate billing.

Step-by-Step Process for Solar Energy System Installation

Rules and Regulations

Technical Standards:

• All solar energy systems must comply with the Singapore Standard SS 601: Code of Practice for the Installation of Photovoltaic (PV) Systems.

• Ensure that all equipment, including inverters and meters, is certified and meets the required standards.

Safety Requirements:

• Follow safety protocols for installation and maintenance, including proper handling of electrical components and compliance with workplace safety regulations.

• The LEW is responsible for ensuring that all safety measures are in place and adhered to during installation and operation.

Regulatory Compliance:

• Adhere to the guidelines set by the EMA and SP Services for the installation and operation of solar energy systems.

• Maintain all necessary documentation, including permits, approvals, and inspection reports, for regulatory compliance.
