Solar Swarm Grids: Sell Your Surplus to Neighbours, Not the Rs8 Grid Buyback (2026 PRIED Study)

Pakistan's rooftops have quietly become one of the world's fastest-growing power plants. Net-metered solar capacity leapt from just 190 MW in 2020 to about **6,978 MW by June 2026** — a nearly 37-fold jump in six years, driven by tariffs that climbed roughly 140% and panel prices that collapsed. But there's a catch that every prosumer now feels: after NEPRA's February 2026 switch to net billing, new solar owners are paid only about **Rs8/unit** for surplus they push to the grid. A new September 2026 study on **solar swarm grids** argues there's a smarter option — sell that surplus to your neighbours instead.

The report comes from the Policy Research Institute for Equitable Development (PRIED), released on 10 September 2026. It reframes the whole rooftop debate: the problem isn't that Pakistan lacks solar power. It's that we waste it.

What is a solar swarm grid?

PRIED defines a swarm grid as a *digitally coordinated, decentralised local electricity network*. Within it, households and businesses can:

• Consume their own solar power first
• Store surplus in batteries
• **Sell extra units to nearby neighbours (prosumers)**
• Buy power from those neighbours when short
• Use the national grid mainly as backup

The key difference from a traditional microgrid is flexibility. A conventional microgrid has fixed boundaries. A swarm grid lets homes and clusters *join, leave, or trade dynamically* — like devices on a mesh network. Think of it as a WhatsApp group for electrons on your street.

Why the Rs8 buyback makes swarm grids attractive

Here's the arbitrage that sits at the heart of the idea. Under the NEPRA (Prosumer) Regulations, 2026, a new solar household exports surplus to its DISCO for roughly Rs8/unit. That same DISCO then sells a unit next door for Rs28–45. Your neighbour pays five times what you were paid — for the exact same electron.

A peer-to-peer (P2P) price set somewhere in between — say Rs15–20/unit — makes *both* sides better off. The seller earns roughly double the DISCO buyback; the buyer saves 30–50% versus their grid tariff. The table below shows the logic.

| Path for 1 surplus unit | Prosumer earns | Neighbour pays | Who captures the gap | | --- | --- | --- | --- | | Net-billing export to DISCO | ~Rs8 | ~Rs30–45 (from grid) | DISCO / national pool | | Swarm-grid P2P trade | ~Rs15–20 | ~Rs15–20 | Split between neighbours | | Wasted / curtailed surplus | Rs0 | Rs30–45 (from grid) | Nobody |

For context, a 10kW rooftop system in Pakistan now costs roughly **PKR 950,000–1,200,000** on-grid and generates 1,000–1,300 units a month. On sunny afternoons much of that spills over while the family is at work — precisely the hours a neighbouring shop, clinic, or tandoor could soak it up.

What the PRIED study actually tested

PRIED didn't just theorise. It ran a techno-economic assessment across two very different settings.

• **Islamabad (urban):** With dense, mixed demand on an established grid, swarm grids were found to be technically feasible *and* commercially viable — capable of being privately financed without heavy subsidy.
• **Tharparkar, Sindh (rural):** Also technically feasible, but with dispersed communities and lower energy density, it would need targeted upfront investment and community capacity-building.

The study's blunt conclusion: Pakistan's core challenge is **coordination, not generation**. We imported over 50 GW of panels against a national installed generation capacity of roughly 41 GW — the hardware is already here. The single biggest obstacle to unlocking it is the **regulatory framework**.

The roadblocks — and PRIED's fixes

Selling power to your neighbour is not yet legal for ordinary households in Pakistan. Only licensed entities can sell electricity, and there's no approved P2P tariff or metering standard. PRIED's companion report, *Swarm Grids: The Next Phase of the Solar Boom*, lays out a transition agenda:

1. **Introduce P2P trading regulations** so prosumers can legally sell to each other. 2. **Standardise equipment** (meters, inverters, protocols) so clusters can interconnect safely. 3. **Open the retail market** through the Competitive Trading Bilateral Contract Market (CTBCM). 4. **Build in gender inclusion** — spousal asset registration and women's participation in installation and operations.

What Pakistani homeowners and businesses should do now

Swarm grids are not something you can plug in tomorrow — the rules aren't there yet. But you can position for them:

• **Size for self-consumption, not export.** With Rs8 buyback, every unit you use yourself is worth far more than one you sell. Our solar system sizing guide helps.
• **Add storage where it pays.** A battery lets you shift afternoon surplus into evening peak — and, later, into a swarm trade.
• **Talk to your street.** Markets, housing societies, and industrial clusters are the natural first swarm grids. Collective demand is what makes the numbers work.
• **Keep records clean.** Standardised, smart-metered systems will be first in line when P2P rules arrive.

The direction of travel is clear. As the Rs8 buyback squeezes the old "export everything" model, the value increasingly lives in your own neighbourhood. Solar swarm grids are how Pakistan could finally capture it.

Frequently Asked Questions

**What are solar swarm grids in simple terms?** A solar swarm grid is a local, digitally managed network where neighbours share and trade rooftop solar power directly — using the national grid only as backup. PRIED's 2026 study says it could turn Pakistan's rooftop boom into community-owned energy.

**Can I legally sell solar power to my neighbour in Pakistan right now?** No. As of September 2026, only licensed entities can sell electricity, and there is no NEPRA-approved peer-to-peer tariff. PRIED recommends new P2P regulations to change this. For now, surplus must go to your DISCO under net billing.

**How much do I get for surplus solar under net billing in 2026?** New prosumers are paid roughly Rs8/unit for exported surplus after the February 2026 net-billing switch — down sharply from earlier rates above Rs25/unit. Consumers approved before the change keep their older, higher buyback for their contract term.

**Are swarm grids cheaper than staying on the grid?** Potentially, yes. A P2P price of Rs15–20/unit sits well below the Rs28–45 grid tariff, so buyers save and sellers earn more than the Rs8 buyback. PRIED found the urban Islamabad model could even be privately financed.

The bottom line

The PRIED study lands a simple, powerful message: Pakistan doesn't need more panels — it needs permission to share them. With over 6,900 MW of net-metered solar and 50 GW of imported panels already in the country, **solar swarm grids** offer a way to escape the Rs8 buyback trap and keep energy value inside your own community.
