MEPCO Peak Hours Schedule and Tariff Rates

By Mepco Bill Editorial Team · editor@mepco-bill.net

What Are MEPCO Peak Hours and Who Do They Apply To?

Peak hours are the time window when electricity demand on the national grid is highest, and MEPCO charges TOU consumers a higher per-unit rate during this period. The critical distinction: peak hours only affect consumers with Time-of-Use (TOU) meters, not standard residential connections.

TOU metering is mandatory for all new consumers with sanctioned load of 5 kW and above, and optional for smaller loads that choose to opt in [citation:1][citation:4]. If your bill shows a single “Units Consumed” figure with one per-unit rate, you are on a standard meter and peak hours do not change what you pay. If your bill breaks consumption into separate “Peak” and “Off-Peak” unit columns, you are on a TOU meter and the schedule below directly affects your charges.

Agricultural tubewell consumers on TOU meters have the strongest financial incentive to shift usage, because their motors can run overnight when off-peak rates apply [citation:20].

Before you can judge whether peak hours matter for you, you need to read your own invoice. That is where a clear understanding of what is MEPCO bill comes in: it is the monthly electricity invoice from Multan Electric Power Company showing your consumer number, meter readings, units consumed, slab rates, taxes, and payable amount. The bill also tells you whether your meter is TOU or flat-rate — which is the single fact that decides whether the peak-hour schedule changes your payment.

MEPCO Peak Hours Schedule by Season (2026)

MEPCO’s peak hours shift with the seasons because daylight hours and demand patterns change. The schedule below reflects the NEPRA-notified TOU periods for MEPCO [citation:2][citation:30].

The window shifts because summer sunset occurs later, pushing the evening demand peak one hour later. Both windows are 4 hours long. There are no morning peak hours — the Power Division confirmed in 2025 that peak hours refer strictly to evening and night hours [citation:12].

If you are unsure which season applies to your current billing month, check the date on your latest MEPCO bill: November through March uses the winter window; April through October uses the summer window.

Peak vs Off-Peak Tariff Rates: What the Rs/kWh Difference Means

TOU tariff rates are set by NEPRA and notified through official tariff schedules. The exact rates depend on your consumer category (residential, commercial, industrial) and your sanctioned load. The general principle: peak rates are 40–50% higher than off-peak rates for the same consumer category.

Historical NEPRA tariff schedules for MEPCO show the rate structure clearly. For commercial TOU consumers, peak rates have been set at Rs 16.00/kWh against Rs 10.50/kWh off-peak — a gap of Rs 5.50 per unit [citation:4]. Current-rate reporting for commercial TOU shows peak at Rs 46.00/kWh and off-peak at Rs 30.00/kWh, a difference of Rs 16.00 per unit [citation:31].

The table below shows representative TOU rate gaps by consumer category. Treat these as illustrative of the structure, not as your exact billable rates — your current bill or the latest NEPRA notification is the authoritative source.

Illustrative rates from NEPRA tariff schedules and current-rate reporting [citation:19][citation:4][citation:31]. Always verify against your latest bill.

For a commercial TOU consumer using 500 peak units and 500 off-peak units in a month, the peak/off-peak split alone changes the energy charge by roughly Rs 8,000 compared to a flat-rate structure. That is why the schedule matters: shifting even one high-consumption appliance — a water pump, an air conditioner, or a commercial freezer cycle — out of the four-hour peak window produces measurable savings.

For a practical walkthrough of how these rates combine with slabs, fixed charges, and taxes on your actual bill, see the MEPCO bill calculation guide.

Worked Example: Monthly Bill Impact of Peak-Hour Use

Here is a concrete worked example for a commercial TOU consumer to show how the peak/off-peak split changes the energy charge. Suppose the meter records 600 peak units and 400 off-peak units in one summer month.

Now suppose the same consumer shifts 200 units out of the peak window into off-peak hours, so the meter records 400 peak units and 600 off-peak units for the same 1,000 total units.

The total units are identical, but the energy charge falls by Rs 3,200 because 200 units moved from the peak rate to the off-peak rate. This is the direct arithmetic behind the MEPCO peak hours schedule and tariff rates: the schedule decides when your units are counted, and the tariff rates decide what each unit costs. Verify your own rates on your latest bill before applying this example to your connection.

Common Mistakes When Reading MEPCO Peak Hours and Rates

Most confusion around MEPCO peak hours comes from a small set of repeated errors. The table below separates what people assume from what actually applies, so you can spot a mistaken assumption before it affects how you plan your usage.

One pattern connects most of these errors: treating peak hours as something every MEPCO consumer experiences. In practice, the peak-hour rate structure is tied to the meter type. If your meter is flat-rate, the clock on the wall does not change what you pay per unit. If your meter is TOU, the clock does matter — but only in combination with your consumption pattern and the applicable tariff schedule.

The safest approach is to start from your own bill. Look for a TOU indicator, separate peak and off-peak line items, or a meter type label. That single check tells you whether peak-hour planning is relevant to your connection at all. Everything else follows from there.

Check Your MEPCO Bill Online Before You Plan Around Peak Hours

You cannot manage peak-hour charges without seeing your own numbers. The good news is that how to check MEPCO bill online is simple, and the same check also tells you whether your meter is TOU or flat-rate.

Here is the basic process for a MEPCO bill check online:

1. Find your 14-digit consumer number on any previous MEPCO bill. It is printed near the top of the bill, next to your name and address.
2. Open a trusted MEPCO bill portal such as mepco-bill.net.
3. Enter the 14-digit consumer number exactly as printed. A single wrong digit returns no result.
4. Submit and view your current bill amount, due date, and billing month on screen.

If you are wondering how do I check my MEPCO bill online without a previous bill in hand, look for your consumer number on any old payment receipt, your electricity meter card, or a bank transaction record where you paid the bill earlier.

The bill view is also where you confirm your tariff category. If you see separate peak and off-peak unit columns, the schedule above applies to you. If you see one unit column, it does not.

How to Get Your MEPCO Bill Online if You Have Never Used the Portal

If you are new to the process, how to get MEPCO bill online comes down to one requirement: your 14-digit consumer number. Once you have it, you can retrieve your current bill in under a minute. There is no separate registration needed on most bill-check services — the consumer number itself acts as your lookup key.

Keep a screenshot or PDF of the bill after you check it. That snapshot becomes useful later when you need to pay the bill, compare peak and off-peak units month to month, or prove payment if a dispute arises.

Practical Steps to Reduce Peak-Hour Charges (If You Are on TOU)

If your MEPCO connection is on a TOU meter, shifting usage out of the peak window is the direct lever. The table below maps common household and small-commercial loads to the best time to run them.

Air conditioning is the honest exception. You cannot easily shift cooling out of a hot evening, which is exactly why the evening window is the peak in the first place. For AC-heavy households, the practical strategy is to reduce total runtime through higher setpoints, insulation, and fan use rather than trying to move the load to another hour.

For everything else — pumps, washing, charging — the shift is simple and the savings show up as a lower peak-unit count on your next bill. That is the number to watch when you check your MEPCO bill online the following month.

How Peak Hours Interact With Slabs and the Protected Consumer Threshold

Peak-hour pricing does not exist in isolation. For residential consumers, the more powerful number on the bill is usually the total monthly units, because that determines your slab and whether you stay in the protected category.

A household that stays under the protected threshold pays a lower rate on every unit. A household that crosses it pays higher slab rates on the units above the threshold. Evening appliance use — AC, iron, washing, water pump — all counts toward the monthly total the same way off-peak use does. So a family that runs heavy appliances after 6 PM can cross the protected threshold partly because of when they used power, even if their total consumption did not feel unusually high.

This is the link between the peak-hour schedule and the bill: on a TOU meter, evening use is both charged at the higher peak rate and counted toward the monthly total that sets your slab. On a flat-rate meter, only the slab effect applies. Either way, the first step is the same — check your current bill and see where your units stand.

Frequently Asked Questions — MEPCO Peak Hours, Tariff Rates, and Bill Checks

What are MEPCO peak hours in 2026?

MEPCO peak hours vary by season. Winter months generally have an earlier evening window, while summer months have a later window. Confirm the current timing from your latest bill or the NEPRA tariff notification.

Do all MEPCO consumers pay a higher rate during peak hours?

No. Peak-hour pricing applies only to TOU meters. Consumers on flat-rate meters pay the same per-unit rate regardless of the time of day.

How do I know if my MEPCO meter is TOU or flat-rate?

Check your latest MEPCO bill for separate peak and off-peak unit columns or a TOU indicator. A single unit column with one per-unit rate means you are on a flat-rate meter.

What is the cheapest time to use electricity on a MEPCO TOU meter?

Off-peak hours are the cheapest window on a TOU meter — the hours outside the notified peak window. The deepest off-peak period is typically overnight.

Does MEPCO peak-hour pricing affect the fixed charges on my bill?

No. Fixed charges are flat monthly amounts and do not change based on when electricity is used. Peak-hour pricing affects the variable per-unit energy charge on TOU meters.

Where can I find the current MEPCO peak-hour schedule?

Your latest MEPCO bill may show the applicable TOU periods. You can also check the NEPRA-notified tariff schedule for MEPCO, which publishes peak and off-peak windows.

If I am on a flat-rate meter, what should I focus on to lower my bill?

Focus on total monthly consumption and your slab position. Reducing overall units used is the lever that moves a flat-rate consumer into a lower slab and lowers the bill.

Are MEPCO tariff rates the same for all consumer categories?

No. Residential, commercial, industrial, agricultural, and other categories have different rate structures. Within residential, protected and non-protected consumers also have different slabs.

What does TOU mean on a MEPCO bill?

TOU stands for Time of Use. A TOU meter records electricity consumption separately for peak and off-peak periods, and each period is billed at a different per-unit rate.

A Final Word on MEPCO Peak Hours Schedule and Tariff Rates

The peak-hour schedule only matters if your meter is TOU. If it is, the winter window runs 5:00–9:00 PM and the summer window runs 6:00–10:00 PM, and every unit you move out of that window is billed at the lower off-peak rate. If your meter is flat-rate, the clock does not change your per-unit charge — your slab and total monthly units do.

Either way, the starting point is the same: check your MEPCO bill online, confirm your meter type and current units, and pay on time to avoid surcharges that have nothing to do with peak hours. Keep your consumer number handy, save your payment records, and use your last two or three bills to see whether shifting appliances is actually moving your peak units down. That is how the MEPCO peak hours schedule and tariff rates turn from a confusing table into real savings on your next bill.
