Load-Shedding Despite Power Surplus: Why Pakistan's Nights Go Dark in 2026

It is one of the strangest contradictions in Pakistan's power sector: **load-shedding despite a power surplus**. Solar has all but killed daytime load-shedding across Punjab, yet millions still lose electricity between roughly 9pm and 4am — the exact hours families need fans, air conditioners and a decent night's sleep. Meanwhile, your bill keeps rising to pay for power plants that sit idle.

If your days are bright but your nights go dark, you are not imagining it. In late August 2026 the Power Division publicly apologised for night-time outages, and Federal Power Minister Sardar Awais Leghari admitted people were "passing through a difficult time." Let's unpack why the nights stay dark — and why only a solar-plus-battery system gives Pakistani homes and businesses real night backup.

Why the nights go dark when there's a "surplus"

Pakistan genuinely has surplus installed capacity on paper. The problem is *when* and *how* that capacity can actually run.

• **Daytime is solved by solar.** Rooftop and utility solar now flood the grid with cheap power from morning to late afternoon, so daytime shortfalls have largely vanished.
• **Night demand peaks — supply doesn't.** After sunset, solar output collapses to zero just as air-conditioning load surges. The grid must lean on expensive thermal plants.
• **Fuel, not turbines, is the bottleneck.** In the current crisis, the non-availability of a single RLNG (imported LNG) cargo knocked out about **3,600 MW** of night-peak generation. Government had to reissue an LNG tender for delivery at Port Qasim and fire up costly furnace-oil plants just to cover the gap.
• **Transmission is weak.** Even where power exists, ageing distribution and transmission infrastructure can't always move it to load centres in Lahore, Multan and Faisalabad.

Capacity charges: paying for plants that sit idle

Here is the part that stings. Under Pakistan's contracts with Independent Power Producers (IPPs), the government pays **capacity charges** — a fee for keeping a plant available — whether or not the plant produces a single unit. You pay for the option to switch it on, even on nights it stays off.

The numbers are staggering. In FY25, consumers paid roughly **Rs 1.81 trillion** in capacity charges — about **Rs 14.3 per unit** — while the actual energy cost was only around **Rs 9 per unit**. Capacity payments made up nearly **61%** of the total electricity bill. Before the CPEC-era plants came online, annual capacity charges were around Rs 384 billion; today the burden has ballooned past Rs 2 trillion, feeding a circular debt of roughly **Rs 1.675 trillion** as of mid-2026.

So the cruel irony is complete: you pay a premium for idle capacity during the day (when your solar covers you) and still get load-shed at night (when that capacity can't run cheaply). You are subsidising the grid's weakness while receiving less of its service.

Why solar alone can't keep your nights lit

Thousands of Pakistani homeowners installed solar expecting 24-hour freedom — then discovered the panels go silent at dusk. A standard grid-tied (on-grid) solar system has three fatal limits for night backup:

1. **No panels, no power.** Solar produces nothing after sunset, exactly when night load-shedding bites. 2. **Grid-tied inverters shut off in an outage.** For safety (anti-islanding), on-grid inverters legally trip when the grid fails — so even a sunny afternoon blackout leaves you dark. 3. **Net metering is now net billing.** Under NEPRA's Prosumer Regulations 2026, new solar consumers no longer get unit-for-unit exchange. The buyback rate for new prosumers was slashed to around **Rs 8–11 per unit**, down from about Rs 25–27. Exporting cheap daytime units and buying back expensive night units is now a losing trade. (Existing net-metering users keep their ~Rs 25.32 rate until their agreement expires.)

In short, solar-only was built for a *daytime* problem. Pakistan's crisis has moved to the *night*. To understand the tariff shift in detail, see how net metering quietly became net billing.

Solar-plus-battery: the only real night backup

The fix is to store your own cheap daytime solar and spend it after dark — on *your* terms, independent of RLNG cargoes and load-shedding schedules. A hybrid (solar-plus-battery) system charges a lithium battery all day, then powers your home through the 9pm–4am danger window.

| Setup | Daytime cover | Night backup (9pm–4am) | Immune to capacity charges? | Value under net billing | |---|---|---|---|---| | Grid-only | ❌ | ❌ | ❌ | N/A | | On-grid solar (no battery) | ✅ | ❌ | Partly | Falling fast | | **Solar + lithium battery (hybrid)** | ✅ | ✅ | Mostly | Best |

With the buyback rate gutted, **self-consumption is now king**. Every unit you store and use at night is a unit you don't buy back at full retail tariff — making batteries the smartest rupee in the system for 2026.

What a solar-plus-battery system costs in 2026 (real PKR)

Battery prices have fallen sharply as LiFePO4 lithium chemistry has gone mainstream. Roughly, expect **Rs 30,000–45,000 per usable kWh** of lithium storage. Here are current market ranges:

| Component | Typical 2026 price (PKR) | |---|---| | 5.12 kWh lithium battery (51.2V 100Ah) | 185,000 – 310,000 | | 10.24 kWh lithium battery (51.2V 200Ah) | 460,000 – 475,000 | | 5 kW hybrid inverter | 80,000 – 230,000 | | 6 kW hybrid system + 5.12 kWh battery (installed) | 550,000 – 700,000 | | 10 kW hybrid system + lithium backup (installed) | 1,400,000 – 1,700,000 |

For a typical Punjab home running fans, lights, a fridge and one inverter AC through the night, a **6 kW hybrid system with 5–10 kWh of lithium** is the practical sweet spot. Pairing a properly sized hybrid inverter with the right lithium battery matters more than adding extra panels you already can't sell profitably.

**One field-tested tip:** size your battery to your *night* load, not your total daily units. Most homeowners over-buy panels and under-buy storage. Add up only what runs from 9pm to 6am (AC, fans, fridge, router) and build the battery around that — it slashes cost while solving the exact hours load-shedding hits. Check current solar panel prices before finalising your ratio.

Frequently Asked Questions

**Why does load-shedding happen at night in Pakistan when there's a power surplus?** Because the "surplus" is mostly daytime solar plus idle thermal capacity. At night, solar stops, air-conditioning demand peaks, and fuel shortages (especially RLNG) plus weak transmission mean the grid can't dispatch enough cheap power. A recent RLNG cargo delay alone cut about 3,600 MW of night generation.

**What are capacity charges and why am I paying for idle plants?** Capacity charges are fixed payments to power producers for staying available, paid whether or not they generate electricity. In FY25 they hit roughly Rs 1.81 trillion — about Rs 14.3 per unit and nearly 61% of the bill — so consumers fund plants even on nights they don't run.

**Can solar panels alone give me night backup?** No. Panels produce nothing after sunset, and grid-tied inverters shut down during outages. Without a battery, solar cannot cover the 9pm–4am load-shedding window.

**Is solar-plus-battery still worth it under net billing in 2026?** Yes — arguably more than ever. With the new-consumer buyback rate cut to around Rs 8–11 per unit, exporting to the grid barely pays. Storing your own daytime solar to use at night (self-consumption) now delivers the best return and real backup.

The bottom line

Pakistan's night blackouts are not a solar failure — they are a grid and fuel failure that solar simply can't reach after dark. As long as you pay capacity charges for idle plants and net billing erodes export value, the only way to guarantee light at 2am is to store your own power. **Solar-plus-battery is no longer a luxury; in 2026 it is the definition of energy security.**
