If the consumer owns a solar PV system and wishes to sell any excess solar electricity to the grid, depending on their contestability status, they may either:

a. Register with SP Services (SPS) under the Simplified Credit Treatment (SCT) or Enhanced Central Intermediary Scheme (ECIS) by requesting the LEW to submit the relevant applications to SPS

b. Directly register with the Energy Market Company as a Market Participant, or

c. Appoint another Market Participant (not applicable to residential consumers)For more information you can refer to the various payment schemes at the EMA website .

Consumers with embedded solar photovoltaic generation can opt for an estimated solar generation output instead of installing the relevant metering arrangement (‘M1 Meters’) at each generation point. The Solar Generation Profile is approved by the Energy Market Authority and is based on factors such as Singapore’s historical average solar irradiance from 7am to 7pm. For more information you can refer to the approved solar generation profile at the EMA website .

This does not apply to building owners who choose to have a solar leasing agreement with an appointed solar vendor (refer to this FAQ for more details).
