As Singapore accelerates its transition to renewable energy, understanding the mechanisms of net energy rebates (NER) is crucial for consumers considering solar energy. This guide provides a detailed overview of the Net Energy Rebate in Singapore, how it works, how to calculate it, how to register, and the distinctions between contestable and non-contestable consumers. Additionally, we will discuss the retail electricity providers in Singapore and how NER is calculated for each. Information is based on early 2024 and might change from time to time so we suggest to check EMA and SP websites for changes.
What is the Net Energy Rebate?
The Net Energy Rebate (NER) is a scheme that allows solar energy system owners to receive financial credits for the excess electricity they export to the grid. This initiative incentivizes solar adoption by offsetting part of the electricity bill with credits earned from exporting surplus energy.
How Does the Net Energy Rebate Work?
Under the NER scheme, excess electricity generated by your solar panels is sent back to the grid. This exported energy is measured by a bi-directional meter and credited to your account at a specific rate.
Calculating the Net Energy Rebate
To calculate the net energy rebate, follow these steps:
- Determine the Amount of Excess Energy Exported:
- Install a bi-directional meter to measure both the electricity consumed from the grid and the electricity exported to the grid.
- Monitor your solar energy system's production and your consumption to identify the surplus energy exported to the grid.
- Find the Export Rate:
- The export rate varies depending on whether you are a contestable or non-contestable consumer. For non-contestable consumers, it is based on the prevailing regulated tariff minus grid charges. For contestable consumers, it is based on the half-hourly wholesale electricity price.
- Calculate the Rebate:
- For non-contestable consumers: Multiply the amount of excess energy exported (in kWh) by the regulated tariff rate, then subtract the grid charge.
- For contestable consumers: Multiply the amount of excess energy exported by the prevailing half-hourly wholesale energy price.
Registration Process for Net Energy Rebate
To participate in the NER scheme, follow these steps:
- Install a Solar Energy System:
- Engage a licensed electrical worker (LEW) and a qualified solar installer to design and install your system.
- Ensure your system complies with the Energy Market Authority (EMA) standards.
- Submit an Application to SP Services:
- The LEW submits an application for grid connection to SP Services.
- Include technical specifications and installation details.
- Inspection and Approval:
- SP Services conducts an on-site inspection to verify compliance.
- Upon approval, SP Services installs a bi-directional meter.
- Register with EMA:
- Register your system with the EMA through their online portal, providing all necessary documentation.
Differences for Contestable and Non-Contestable Consumers
Non-Contestable Consumers
Non-contestable consumers buy electricity from SP Services (SPS) at a regulated tariff. They are eligible for the Simplified Credit Treatment (SCT) Scheme, where they receive credits for surplus energy at the prevailing regulated tariff rate, minus grid charges (approximately 6 cents). This means they are reimbursed for about 75-80% of the electricity price for the energy generated.
Contestable Consumers
Contestable consumers can purchase electricity from retailers or the wholesale market at prevailing rates. They are eligible for the Enhanced Central Intermediary Scheme (ECIS), where surplus energy is credited based on half-hourly wholesale energy prices. While potentially more volatile, this scheme can be advantageous for consumers with high energy exports during peak pricing periods.
Retail Electricity Providers in Singapore and NER Calculation
Here are some of the retail electricity providers in Singapore and how the NER is calculated for each:
- SP Group
- Non-contestable consumers under SP Group receive credits based on the regulated tariff minus grid charges.
- For contestable consumers, credits are based on the half-hourly wholesale market rate.
- Keppel Electric
- Offers competitive fixed price plans and discounts off the regulated tariff.
- NER credits are calculated based on the wholesale market rate for contestable consumers.
- Sembcorp Power
- Provides fixed rate and discount off regulated tariff plans.
- NER credits for contestable consumers are based on the wholesale market rate.
- Geneco
- Offers fixed price plans, discount off regulated tariff plans, and renewable energy plans.
- NER credits for contestable consumers are based on the half-hourly wholesale rate.
- iSwitch
- Provides fixed price plans and discounts off the regulated tariff.
- NER credits are calculated based on the wholesale market rate for contestable consumers.
- PacificLight
- Offers fixed price plans and discount off regulated tariff plans.
- NER credits for contestable consumers are based on the wholesale market rate.
- Ohm Energy
- Offers fixed price plans and discount off regulated tariff plans.
- NER credits for contestable consumers are based on the half-hourly wholesale rate.
Examples and Financial Implications
- Consider a non-contestable consumer with a solar panel system generating 500 kWh surplus energy per month. If the prevailing regulated tariff is 0.30 SGD per kWh, they would receive:
Rebate=500 kWh×(0.30 SGD/kWh−0.06 SGD/kWh)=120 SGD
- For a contestable consumer, if the average half-hourly wholesale price is 0.25 SGD per kWh, they would receive:
Rebate=500 kWh×0.25 SGD/kWh=125 SGD
