Uniform Singapore
Energy Price (“USEP”)
The USEP is the uniform price of energy that is determined in the Wholesale Electricity Market
(“WEM”). It is the weighted-average of the nodal prices at all off-take nodes in each half hour.
2.
Energy Market
Company (“EMC”) &
Power System
Operator (“PSO”) Fees
These fees recover the approved costs for EMC and PSO to operate the WEM and the power system in
each fiscal year, respectively. These fees are levied on both generation companies (“gencos”) and
retailers based on per MWh generated or consumed.
For NMPRs, the EMC and PSO fees will be included in the Retail Settlement Uplift Charge which is an
item of the Market Support Service Charges (refer to the Other Charges table below).

Hourly Energy Uplift
Charges (“HEUC”)
This charge reconciles any differences between total amount received from retailers and total amount
paid to gencos for energy, reserve and regulation products. It is usually a negative value, i.e. a return to
wholesale market purchasers.
4.
Monthly Energy Uplift
Charge (“MEUC”)
At the end of each calendar month, EMC calculates the MEUC for the following calendar month and
recovers it from the load on the basis of withdrawal quantity in MWh. This charge, levied on retailers,
covers the following potential payments and receipts each month:
 cost of procuring contracted ancillary services (e.g. black-start services) and related costs,
 compensation claims and financial penalties, and
 estimated monthly energy uplift shortfall to be recovered in the following calendar month.
5.
Allocated Regulation
Price (“AFP”)
The cost of purchasing regulation products from the market is co-shared by retailers and gencos. The
AFP is determined for retailers based on their consumption (metered withdrawal quantities), and for
gencos based on their injected energy quantity, up to 5 MWh per settlement period.

vesting contract credits/debits to the retailers, the non-contestable consumers and those contestable
consumers who purchase electricity from the pool. Retailers may or may not pass on the vesting
