and reliability.
Building any one of these without the others can create another bottleneck.
A badly engineered 10 kW solar system remains badly engineered even if every component has a famous brand name.
A badly coordinated 50 GW electricity system has essentially the same problem—just several orders of magnitude larger.
What Happens to the DISCO?
Competitive electricity does not necessarily mean distribution companies disappear.
Their role can change.
Even if a customer purchases energy from another supplier, electricity still has to cross physical infrastructure.
Wires remain valuable.
Transformers remain valuable.
Meters remain valuable.
Network maintenance remains essential.
A mature electricity market separates the commodity from the network more clearly.
You may have competition over who sells you electricity while the local wires remain regulated infrastructure.
Pakistan is only at the beginning of that transition.
And What About the Ordinary Household?
The first 400 MW auction is not designed around the typical residential consumer.
The initial market is for large users. ISMO
So nobody should read this development and expect to choose between five electricity retailers for their Lahore home next month.
But electricity-market reforms often begin with large consumers because their metering, demand profiles and commercial sophistication make them easier to introduce into bilateral markets.
What matters to households today is the direction of travel.
First came captive generation.
Then rooftop solar.
Then prosumers.
Then batteries.
Now large consumers begin receiving supplier choice.
The electricity consumer is gradually becoming a more active participant in the energy system.
There Is Also an Important Warning
Markets are not automatically competitive merely because we call them markets.
A successful CTBCM will depend on whether participants can genuinely compete.
That means transparent rules.
Non-discriminatory grid access.
Predictable network charges.
Credible metering.
Reliable settlement.
Adequate transmission capacity.
Competition among suppliers.
Enforceable contracts.
Transparent congestion management.
And a regulator capable of policing market power.
NEPRA itself required ISMO to publish anonymised aggregate information after auctions to improve transparency and market understanding. It also clarified an important point: the approved 800 MW wheeling quantum represents demand, not an automatic 800 MW of generation, because generation requirements must account for losses, capacity obligations and reliability. NEPRA
That distinction is exactly the kind of engineering precision Pakistan’s electricity debate needs more of.
From Solar Installer to Energy-System Thinking
This is ultimately why the podcast went far beyond panels.
When I entered solar, the industry was much smaller.
The conversation was about photovoltaic modules, inverters, irradiation and installation.
Today I find myself discussing batteries, distribution networks, grid codes, consumer behaviour, capacity payments, electricity markets and bilateral energy contracts.
That isn’t mission creep.
It is what happens when distributed solar becomes large enough to alter the electricity system around it.
Solar is no longer merely a product installed on top of the electricity market.
It is becoming one of the forces reshaping that market.
My Biggest Addendum to the Podcast
If I were recording the conversation again today, I would add one question:
What happens when Pakistan’s solar revolution meets an electricity market in which consumers can increasingly choose their suppliers?
That is where things become genuinely interesting.
A factory might generate some electricity itself.
Store some.
Buy some from the grid.
Contract some from an independent renewable generator.
Shift some consumption to cheaper hours.
Electrify processes previously powered by fossil fuels.
And eventually optimize all of these decisions through software.
At that point, the distinction between a “solar system” and an “energy system” begins disappearing.
That is the transition I think Pakistan’s energy industry should be preparing for.
Not solar versus grid.
Not batteries versus grid.
Not IPPs versus rooftop panels.
But an electricity system in which generation, storage, networks and consumers interact far more dynamically than they do today.
The first 400 MW competitive wheeling auction is small beside Pakistan’s overall electricity system. But first auctions matter because they establish rules, behaviour and confidence.
Pakistan’s solar revolution gave consumers the ability to generate.
Competitive electricity markets could eventually give them something else:
the ability to choose.
And that may be the more important revolution.
