There is a concept in economics called sensitivity analysis. In this we determine when does option B become more better than option A.
Let's say today you need 5000 mw. This will cost you say 1 billion dollars. But 10 years later you will need additional 5000 mw which at that time will cost 0.8 billion dollars.
That's the first option.
These are good options for fully developed nations to consider. They don't apply to developing Pakistan which lacks infrastructure needed for its 800,000 sq km area and it's 257 million people.
But second option is that you can directly build capacity of 10000 mw now. Costing 2 billion dollars.
Now tell me which option is best, economically ??? Build full capacity now or go staged ? When does option A become better then option B ?
Nothing is being installed in one go now. It'll take 5-10 years to get that capacity, and by that time Pakistan's population would've grown by 20-40 million people by then.
All the decisions should be made based on these analysis. How much will each option cost. How much economic pressure will each option put us into. Can we afford it now or maybe later. Etc
Delayed decisions will cost even more.
Let's not forget the debilitating electricity issue that Pakistan faced between 2008-2013 when load-shedding lasted 18-22 hours daily, and segments of the industry shifted to Bangladesh and it's still there.
Nobody wants to return to that sort of situation again.
Our current need is only 30000ish mw. While our installed capacity is 60000 mw.
Our installed capacity is 48 GW.
Demand of electricty (from national grid) for agricuture, residential, and indistry have declinded due to soalr. And further declining.
I must disagree.
I just spoke with my relatives in Pakistan and they said they're facing load shedding even today, on the day Eid.
Do we really need to expand the production capacity now ? While we are still enjoying additional capacity of 30000 mw more than our need ?
We're not enjoying anything. If there was additional capacity that isn't being utilised, there would be no load-shedding and instead each household in Pakistan would have 24/7 electricity.
Why are China and Germany as two examples, increasing their overall electricity capacity year after year with no end in sight?
Here's a good read from the
IEA on the global demand.
Electricity demand growth surged in 2024
Global electricity demand increased by 4.3% in 2024, a step change from the 2.5% growth seen in 2023. The average pace of electricity demand growth from 2010 to 2023 was 2.7%, double the rate of total energy demand growth over the same period. Electrification picked up across sectors, raising electricity demand in most major economies in 2024.
China accounted for the largest share of electricity consumption growth, but increases were seen globally
Almost all regions saw an acceleration in the rate of electricity consumption growth in 2024 compared with the annual average from 2012 to 2022. Globally, electricity consumption increased by 1 080 TWh, nearly two times the annual average of the past decade.
