Introduction: A New Era for Solar Business in Pakistan
For years, we only had Net Metering. You sold power to the government (WAPDA/KE). But what if you could sell your solar power directly to a factory, a plaza, or your neighbor?
This is now becoming possible.
In December 2025, the Cabinet Committee on Energy (CCoE) approved a historic plan: an 800MW Pilot Auction for power wheeling. This opens the door for B2B (Business-to-Business) energy trading.
This guide explains the new CTBCM model and the ISMO authority in simple words.
What is CTBCM? (The “Open Market” for Electricity)
CTBCM stands for Competitive Trading Bilateral Contract Market.
Think of it this way:
- Old System (Single Buyer): Everyone must sell to the government (Central Power Purchasing Agency). The government sets the price.
- New CTBCM System (Open Market): You (the seller) can sign a contract directly with a buyer (like a textile mill). You agree on a price that is lower than the grid but higher than the government rate.
This creates competition. It breaks the government monopoly.
Who is the Referee? Meet “ISMO”
To make this work, Pakistan has created a new authority called ISMO (Independent System and Market Operator).
ISMO is like the “Traffic Police” of the electricity grid.
- It does not buy or sell power.
- It only manages the flow.
- It ensures that when you sell 1 MW to a factory, the grid wires transport it safely.
Why is this good? Before, the government controlled everything. Now, ISMO is an independent referee, ensuring fair play for private solar businesses.
The Dec 2025 Breakthrough: The 800MW Auction
Last month (Dec 2025), the government approved a Pilot Project. They are auctioning the rights to wheel (transport) 800 MW of power.
- Who is it for? Mostly for large “Bulk Power Consumers” (BPCs) like factories, universities, or housing societies with a load of 1 MW or more.
- The Opportunity: If you have a large roof or piece of land, you can install a commercial solar setup. Instead of Net Metering (where rates are dropping), you can sell this power to a nearby industry at a premium rate.
This is the first step. Soon, this might open up for smaller users, too.
How “Wheeling” Works for Your Business
“Wheeling” means using the existing WAPDA/KE wires to send your electricity to a buyer.
- Generation: You install a 1 MW+ solar system with Enon Traders.
- Contract: You find a factory that pays Rs 40/unit (cheaper than the grid’s Rs 50).
- Wheeling Charge: You pay a small “toll tax” (Wheeling Charge) to the grid company for using their wires.
- Profit: You earn more than with Net Metering, and the factory saves money. It is a win-win.
Enon Traders: Ready for the B2B Revolution
The rules of the game are changing. Net Metering is for homes; CTBCM is for businesses.
Enon Traders is preparing for this shift:
- Commercial Solar: We design large-scale solar solutions ready for B2B trading.
- Grid Compliance: Our systems meet the strict technical standards of ISMO.
- Feasibility Studies: We help you calculate if selling to a neighbor is better than Net Metering.
Final Conclusion
The 800MW Auction is just the beginning. The future of solar in Pakistan is not just saving money—it is making money by becoming an energy company yourself.
With ISMO now active, the grid is finally opening up. Are you ready to trade?
