Spot electricity prices have hit a 2026 high. Will this raise my household bill?
Besides being heavily influenced by fuel costs, the USEP is affected by real-time power supply and demand.
Singapore's wholesale electricity prices have reached a record high of $486.21 per megawatt-hour (MWh) in the week of September 13 to 19, 2026. This surge is primarily driven by the conflict in the Middle East, which is causing volatility in the price of natural gas, the main fuel source for power generation in the country. The Uniform Singapore Energy Price (USEP), the spot price for Singapore's wholesale electricity market, is heavily influenced by fuel costs and real-time power supply and demand.
The Energy Market Company (EMC) compares the USEP to "dynamic ride-hailing surge pricing", as it recalculates every 30 minutes based on supply and demand. While the USEP does not affect the regulated tariff that most households purchase electricity at through SP Group, fluctuations in fuel costs do impact the tariff. The tariff, set quarterly by SP Group, is heavily influenced by average daily natural gas prices in the first 2½ months of the preceding quarter.
For instance, households on the regulated tariff may not be affected by the recent price increases, but those on fixed-price retail contracts could see higher bills if the USEP remains high. SP Group has warned that supply disruptions due to the Middle East conflict have led to the need for replacement fuel, which is more expensive and raises power generation costs.
