TNB Bill Too High? The 2026 Time of Use (TOU) Hack You Need to Know
If you own an Electric Vehicle (EV) or run your air-conditioning heavily at night, paying the standard TNB tariff is like throwing money away.
This is the #1 secret for Malaysian homeowners in 2026: Electricity prices are not the same all day long.
Let’s break down the strategy: The Time of Use (TOU) Tariff.
“My electricity bill is over RM500 every month because we sleep with 4 air-conditioners on every night. It feels impossible to lower the bill without sweating.”
Switch to TNB’s Time of Use (TOU) tariff. By shifting your heavy usage to “Off-Peak” hours (after 10 PM), you pay a ~20% lower rate for the exact same amount of electricity. No need to turn off the AC; just turn it on at the right time.

How to Maximize Savings (The Ultimate Strategy)
TOU saves you money at night. But what about the expensive Peak Hours (2 PM – 10 PM)?
Strategy: Combine TOU with Solar Panels.
- Daytime: Solar panels generate free electricity to cover expensive Peak rates.
- Nighttime: Use the cheap TOU Off-Peak rates from the grid.
