America's largest power grid is under strain as data centers and AI chatbots consume power faster than new plants can be built.

Electricity bills are projected to surge by more than 20% this summer in some parts of PJM Interconnection's territory, which covers 13 states - from Illinois to Tennessee, Virginia to New Jersey - serving 67 million customers in a region with the most data centers in the world.

The upheaval at PJM started a year ago with a more than 800% jump in prices at its annual capacity auction. Rising prices out of the auction trickle down to everyday people's power bills.

For context: In 2019, I was paying $0.09/KWh and today I pay about $0.29/KWh with yet another rate hike looming.
