(KTEN) -- As millions of Texans remain in the dark and cold; frustration grows. Texas hears you, we hear you. Gov. Greg Abbott gave an update on the state's emergency response Wednesday afternoon to try and clarify the situation.

But there remains uncertainty about when the lights will come back on for hundreds of thousands of Texans, and also about how this happened. Any planned blackouts were supposed to be "rolling," but then they switched to "controlled" power outages.

Then it was complete chaos with a failed power grid.

"Every source of power the State of Texas has access to has been compromised because of the over-cold temperatures or because of equipment failures," Abbott said.

Texas relies heavily on natural resources to fuel power, and when natural gas and wind generators fail, there isn't enough power, forcing state leaders to act quickly.

"I have, earlier today, issued an order effective today through February the 21st, requiring those producers that have been shipping to those locations outside of Texas to instead sell that natural gas to Texas power generators," the governor added.

Getting those resources back on the grid will get more people out of the dark; it's just a waiting game.

The Electric Reliability Council of Texas has been taking the heat for leaving so many Texans in the dark. ERCOT CEO Bill Magness stands by the council's decision to pull the plug. Magness said the risk could have been a blackout of the entire system that would have resulted in monthly outages.

"We had to reduce the demand to get the supply and demand back in balance," he said. "We've been working to get that balance back so that we can operate the system reliably and safely going forward."

Lots of unknowns remain, but Abbott said state legislators will review the preparations and decisions by ERCOT to get a full picture of what caused the outages and to identify long-term solutions.

Meanwhile, the White House is providing generators to Texas and was preparing to move diesel fuel into the state, while FEMA is supplying Texas with water and blankets.
