Guide To Off-Peak Electricity Plans: Geneco, Senoko Energy, PacificLight Energy, Keppel Electric

The Open Electricity Market (OEM) gives households more choices when buying electricity. Among these are peak and off-peak, or time-of-use, plans, which charge different rates depending on when we use electricity. They can suit households that use more power at night, but the cheaper off-peak rate alone does not tell us whether the overall bill will be lower.

For 1 October to 31 December 2026, SP Group’s regulated tariff is 31.16 cents per kWh including GST. Here is how the published off-peak plans compare as at 14 October 2026. Rates can change for new sign-ups, so check the retailer’s quotation and fact sheet before committing.

The periods are different, so a household that returns home at 7pm may benefit from a different plan than one whose main electricity use is overnight. An advanced meter is required to measure usage in the relevant intervals; check installation charges and any waiver offered.

#1 Geneco

Geneco’s Get It 7 To 7 is a 24-month plan charging 27.90 cents per kWh from 7pm to 7am and 32.50 cents from 7am to 7pm daily. Its published fact sheet is dated 24 August 2026.

The early start of its off-peak window suits a couple who leave for work in the morning and return after 7pm. However, daytime usage on weekends still attracts the peak rate. Geneco’s fact sheet provides for absorption of one S$43.60 advanced-meter installation fee when signing up for this plan for the first time.

Before fees or optional add-ons, about 29% of total consumption would need to fall in its off-peak window to beat the current SP tariff. That compares energy charges only; it does not establish that the plan is cheaper than every flat-rate retail offer.

#2 Keppel Electric

Keppel Electric’s Weekend Saver has a 24-month term. Its published fact sheet charges 27.90 cents per kWh overnight from 9pm to 9am on weekdays, and throughout weekends. Weekday usage from 9am to 9pm costs 39.90 cents per kWh.

The weekend rate can suit households that do laundry and other electricity-intensive chores then. The trade-off is the higher weekday peak rate, which applies during the early evening as well as the working day. A smart-meter installation costs S$43.60 if applicable.

At these rates, about 73% of total consumption needs to fall in the cheaper periods to beat the current SP tariff on energy charges alone. Weekend discounts are useful only if they outweigh the extra cost of weekday peak usage.

#3 Senoko Energy

Senoko’s LifeSavvy24 charges 20.05 cents per kWh from 11pm to 7am daily, and 36.95 cents from 7am to 11pm, over a 24-month term. Its published offer includes a waiver of the S$43.60 advanced-meter installation cost.

The eight-hour off-peak window is narrower than Geneco’s, but its overnight rate is lower. It can therefore suit households with substantial overnight air-conditioning use, while families using most of their electricity for dinner, entertainment or chores before 11pm may benefit less.

About 34% of total consumption would need to occur between 11pm and 7am to beat the current SP tariff on energy charges alone.

#4 PacificLight Energy

PacificLight offers two relevant options. Its 9 To 9 fact sheet dated 7 October 2026 lists 20.05 cents per kWh from 9pm to 9am, 36.95 cents from 9am to 9pm and a S$1.01 daily charge. It has no fixed contract term, but termination requires 10 business days’ notice. Rates may change with at least 10 business days’ notice.

The daily charge adds S$30.30 to a 30-day bill before any electricity is used. This makes the plan harder to justify for low-consumption households, even when much of their usage is overnight. An advanced meter is required, with an installation fee of S$43.60 if applicable.

The Save While Sleeping 24 fact sheet dated 8 October 2026 instead lists 23 cents per kWh from 11pm to 7am and 33 cents from 7am to 11pm, over 24 months. It does not list the S$1.01 daily charge, but requires an advanced meter and includes early-termination charges.

Save While Sleeping needs about 18% overnight consumption to beat the current SP tariff on energy charges alone. Its longer commitment and other applicable charges should also enter the decision.

How Much A Young BTO Couple Saves When Switching To A Peak And Off-Peak Plan

When choosing an electricity plan, it is best to maximise savings with minimal changes to our lifestyle. The original example in this article, written in October 2025, described my partner and me leaving our BTO flat around 8am and returning after 7pm on weekdays. The screenshot below shows that earlier weekday usage pattern.

Source: SP Services mobile app screenshot from the original October 2025 article.

To compare current prices consistently, assume five weekdays with 5 kWh of daily usage: 1 kWh between 7am and 7pm, 1 kWh between 7pm and 11pm, and 3 kWh between 11pm and 7am. On each weekend day, assume 7 kWh. This is an illustrative allocation, rather than an exact reconstruction of the screenshot, totalling 39 kWh per week.

The calculation excludes sign-up rebates, optional add-ons, meter installation and other conditional fees. Under these assumptions, Save While Sleeping 24 has the lowest recurring energy cost, about S$0.78 less per week than SP. Keppel’s weekend discount produces only a small saving because its weekday peak price is higher.
