About Monthly Energy Uplift Charges
At the end of each calendar month, EMC calculates the Monthly Energy Uplift Charge (MEUC) for the following calendar month and recovers from the load on the basis of withdrawal quantity in MWh. This charge levied on retailers, covers the following potential payments and refunds each month:
- The cost of procuring contracted ancillary services (e.g., black-start services) and related costs, compensation claims and refunds,
- Financial penalties and refunds, and
- The estimated monthly energy uplift shortfall is to be recovered and/or deducted in the following calendar month.
Numerical information on the MEUC is determined in accordance with the Market Rules Chapter 7, section 4.1.
A. For customers on OEM Fixed Price Business Plans (with successful sign-up/renewal prior to 1 Sep 2022)
The increase to your Electricity Charges for each month shall be calculated based on the difference in the MEUC for that month as compared to the May 2022 MEUC of S$0.00017/KWh (“Incremental Charges”). In the event that any month’s MEUC is less than S$0.00017/KWh, there shall be no Incremental Charges nor any rebate provided.

Sample calculation for a 230V Low Tension customer consuming 4,000 KWh for the month of August
Incremental Charges (MEUC)
= Monthly Consumption (in KWh) x Incremental Charges ($/KWh) x Transmission Loss Factor
= 4000kWh x $0.00374/KWh x 1.036482
=
$15.51
B. For customers on OEM Fixed Price Business Plans (with successful sign-up/renewal after 1 Sep 2022)
MEUC will be charged on a passthrough basis.
*MEUC is subject to further adjustment by the applicable Transmission Loss Factor.

About Transmission Loss Factors
Transmission Loss Factors are scaling factors applied at the metering point to account for network and transformer losses.
Refer to the table below for the transmission loss factors for the respective loads. The factors are derived using the methodology approved by the Energy Market Authority.
