Exporting Excess Solar Energy
EXPORTING EXCESS SOLAR ENERGY TO THE GRID
Most residential solar energy systems are <1MW.
Here's a little snapshot for people in a hurry!
- Madeline has installed a total of 0.5 MW (500kW) on her landed property
- She currently buys electricity from an electricity retailer which makes her a Contestable Consumer
- To sell back excess solar energy to the grid, Madeline will have to register with SP Group under the Enhanced Central Intermediary Scheme (ECIS).
- Madeline will be paid based on the half hourly USEP (Uniform Singapore Energy Price) rate which can be found at the EMC website.
- Andrew has installed a total of 0.4 MW (400kW) on his landed property
- Andrew currently buys electricity from SP Group which makes him a Non-Contestable Consumer
- To sell back excess to the grid, Andrew will have to register with SP Group under the Simplified Credit Scheme (SCS)
- Andrew will be paid based on the SP Quarterly regulated tariff minus GST & grid charges.
Getting paid for exporting back to the grid is widely known overseas and around the general web as "Net Metering". We just call it export to grid or sell back to grid here in Singapore, so don't get too caught up with buzzwords!
