Twenty years ago wind and solar were a rounding error on the Texas grid. Today more than a third of the power comes from them, and the share has risen every year.

In the Houston-area example (77002) today, the cheapest plan is already 100% renewable. The premium is zero.

Across the 5 delivery territories we price, the cheapest 100% renewable plan is within 1¢/kWh of the cheapest plan of any kind in 5 of them, and in 5 of those it is the cheapest plan, full stop.

Wind and solar already supply about a third of the power on the Texas grid, so a renewable plan isn't buying something rare.

A 100% renewable plan is a normal plan whose provider retires renewable energy certificates to match your usage — the electrons, the wires, and the delivery charge are identical.

That is why the premium is small, and often zero.
