4 important points about your surplus solar energy that installers & E-retailers don’t tell you about. (Residential)

Most residential solar energy systems are <1MW.

Mainly refers to landed property owners.

As a solar owner, have you ever wondered what happens to the excess generated solar energy that your home does not consume? Here we will talk about 4 important points that your installers and electricity retailers do not tell you about!

(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!)

1. Identifying your consumer profile and applying for SCS or ECIS.

You are eligible to apply for either:

SCS: Simplified Credit Scheme if you are a non contestable consumer (You buy electricity from SP Group).

ECIS: Enhanced Central Intermediary Scheme if you are a contestable consumer (You buy electricity from an E-Retailer).

Energy Market Authority resources: EMA guide to solar pv | EMA Determination Document

2. If you do not apply for any of the available schemes, your excess energy is exported to the grid for FREE.

Which means you are doing free service! The Grid thanks you!

3. If you are looking to export to the grid, you will need an AMI (Advanced Metering Infrastructure) meter.

– If you have not switched to an electricity retailer (eg: SP Group), you can contact them to install one for you.

– If you have switched to an electricity retailer, you will have to contact them to get an AMI installed and you will be charged for it ($42.80 inclusive of 7% GST) Note: they will contact SP to do it but it will be administered under your electricity retailer.

4. Your exported energy will be paid based on your consumer profile

SP Group(non contestable)= Quarterly regulated tariff MINUS(-) 7% GST MINUS(-) $0.05

Electricity Retailer (contestable)= half hourly USEP (Uniform Singapore Energy Price) rate which can be found here (link). 

Here is a little snapshot for people in a hurry.
