I'm not quite so sure about that interpretation... there was an early Renewable Portfolio Standard around 2000, yes. But that was for tiny amounts compared to what independent generators are putting on to the grid these days. Compared to a standard utility, which is a regulated monopoly that does five year planning based off old data and the inertia of a large corp with no competition, the Texas energy market is the Wild West. Nearly anybody can connect their project to the grid and sell at the prices they want to sell at. And that's why Texas is installing massive amounts of battery storage, wind, and solar, compared to new natural gas. There's no mandate for GW of battery capacity, it's just people thinking they can make a buck on arbitrage of all the wind and solar electricity.
