The state of grid flexibility across US electricity markets.
Demand is rising. Dispatchable supply is shrinking. Flexibility can fill the gap, but activation is uneven.

Which markets are ready for flexibility, and what's in the way?
Flexibility value exists in every major US electricity market. The path to capturing it varies.
The constraint differs in every market. In some, the infrastructure is deployed but dormant. In others, the market works but the value is shifting. This comparison shows the system need, the activation path, the value at stake, who holds the decision rights, and whether the opportunity is durable across all seven major US ISOs.
The two largest demand response programs (MISO and PJM, with a combined 13 GW enrolled) deliver at 22-31% utilization when called. Texas has 93% smart meter coverage but price signals reach fewer than 1% of customers through formal channels. New England and New York have the highest wholesale prices but the lowest smart meter deployment, locking residential customers out of the opportunity. California has the most complete activation pathway of any market, and its challenge has already shifted from responding to scarcity to managing solar oversupply.
Each market has a different constraint and a different path forward. The map below shows where retirement pressure and transmission constraints concentrate geographically.
