The Solar Generation Profile is a model approved by EMA to help determine compensation and is used in financial settlements.
Overview
Consumers with embedded solar photovoltaic generation can choose to use estimated solar generation output instead of installing M1 meters at each generation point (refer to diagram below).

This estimated solar generation output is determined by a Solar Generation Profile used for financial settlement in the wholesale electricity market.
To access the Solar Generation Profile, consumers need to register with SP Services under the Enhanced Central Intermediary Scheme or with the Energy Market Company.
The Solar Generation Profile is approved by EMA and is based on factors such as Singapore's historical average solar irradiance from 7am to 7pm. It is standardised for all consumers with embedded solar photovoltaic generation facilities and will be updated as new information becomes available.
Consumers with embedded solar photovoltaic generation facilities will be compensated for the actual generation that is sold back to the grid. They will pay for the actual electricity consumed from the grid, which will be measured by M2 meters at the intake point (refer to diagram above).
