Arkansas shares the power grid with a number of other States. Almost the whole of the Nation is suffering unusually severe weather, and a substantial portion of the power generation normally present is now offline. TX, for instance, has installed a tremendous amount of wind and solar - which normally are pretty reliable, but are currently ether frozen or buried under snow, providing nothing to the grid. there is no significant source of "storage", nor could it supply such a severe and persistent load.
TX is not alone in those choices.
This is not meant to be political. There are no easy answers, merely trade-offs. Coal plants have become increasingly uneconomical to operate, both due to greatly reduced costs of natural gas (courtesy "fracking") and increasingly expensive mandatory emissions capturing technologies, plus difficulties with disposal of (comparatively) heavily radioactive coal ash. Natural gas plants (or converted coal) have taken on a lot of that supply, supplemented by less reliable, but lower carbon, cheaper to operate wind and solar. The nation has an aversion to Nuclear, aggravated by disposal problems of its own - Yuca Mountain containment is now, what, 50 years delayed? The system is designed so that as some sources go offline during periods of either calm or extreme winds, overnight, etc, other plants spin up to provide power and transfer it across the grid. But when a weather event this widespread occurs, it overwhelms the ability of non-affected plants to meet the increased needs
As well, the nations population continues to grow relative to where it was 20, 30, 60 years ago when most of these plants were contemplated, permitted, and built. Per capita power consumption is growing too - which will only grow further as the nation shifts from gasoline to electric vehicles. CA is leading the charge by insisting it can "supplement" its inadequate power generation by draining the batteries of electric vehicles during periods of high usage, which sort of begs the question of when those vehicles will actually get charged...
tl;dr: "Growing Pains"
My wife and I live in an RV in the country, high winds take local power lines down (ours are buried) frequently. I've lost power several times while incubating with only limited difficulties/adverse effect - but never more than a few hours, and at temps around 40-50, not sub freezing.
I wish you and yours all the best. Stay safe, and our hopes for a successful hatching.
