Kerala's lights run on rain.
And right now… the rain isn't showing up.
The Idukki dam — the beating heart of Kerala's power grid — has dropped to just 24% storage.
Last year, this same week? 52.4%.
Less than half of what the state had at this point in 2025. 😬
The southwest monsoon hit Kerala on June 4 this year — four days late, marking IMD's first big forecast miss since 2015.
And it's been underwhelming ever since.
India is now staring at a 36% rainfall deficit as of late June.
In Kerala, 10 of 14 districts are running deficient.
On Wednesday, the Idukki catchment got a measly 13.2 mm of rain.
Enough inflow to generate just 3.111 million units of power.
That's barely a trickle for a reservoir built to feed an entire state.
Here's the snapshot from KSEB's biggest reservoirs right now:
Only Kallarkutty is breathing easy at 65%.
The total juice left in Idukki? About 513.5 million units of electricity.
Sounds like a lot. It isn't.
Moolamattom, the underground powerhouse, burned through 3.36 million units in a single day.
Do the math. 🧮
Executive Engineer Jameela Beegam isn't sugarcoating it.
If the rains don't intensify soon, power generation schedules will have to be cautiously managed.
That's polite engineer-speak for: brace yourself.
Kerala has been here before — 2016, 2017 — when dry monsoons forced load management and emergency power purchases from the national grid.
Every unit bought from outside costs more.
Every week without rain tightens the screw.
This isn't just a dam story.
It's a climate story.
It's an energy security story.
It's a reminder that an entire state's electricity bill can swing on whether clouds break over a few hills in the Western Ghats.
Kerala is praying for a July revival.
Until then, every millimetre matters.
And Idukki is watching the sky.
That's all for now!
