Grid-scale batteries became dramatically cheaper.

The average fully installed utility-scale battery project cost fell from about $2,571 to $192 per kWh between 2010 and 2024.

THE YOTTABIT PERSPECTIVE

What does it mean to me?

Big change is fascinating. Its implications are what matter.

More affordable storage can gradually affect resilience and electricity choices, though costs and availability vary by place.

Businesses can revisit the economics of shifting demand, backup energy and peak charges.

Utilities and industrial energy users must rethink planning assumptions formed when storage was far more expensive.

FROM JIM CARROLL’S WORK

Jim’s 2026 energy keynotes emphasize how storage changes the relationship between electricity and time.

WHAT COULD I DO MONDAY MORNING?

Revisit one energy assumption made five years ago. Does the current cost structure justify a fresh analysis?
