The darkness that enveloped a large chunk of northwest Harris County Tuesday night was the result of a fire at a CenterPoint substation in the 12300 block of Kluge Road.
According to Center Point, they have now restored power to more than two-thirds of the customers impacted by the fire.
Crews will be working through the night and into the morning to repair facilities and restore power to the remaining customers.
Officials say some of those customers may not be restored until tomorrow due to the damage from the fire.
Explosions could be heard soon after the Cy-Creek Fire Department and EMS arrived on the scene.
Large Plumes of smoke could be seen for miles.
That resulted in a shelter in place order for some nearby residents.
They were told of they could see smoke in their neighborhood to stay indoors.
No injuries were reported and the cause of the fire remains under investigation.
The biggest headache the blaze caused was widespread power outages.
At around 7pm last night CenterPoint was reporting 75 thousand customers had no power.
In a tweet CenterPoint said customers without power should prepare to be in the dark for 10 to 12 hours.
