A new report details the issues that led to energy saving warnings across Texas in June.
ERCOT tracked more than 1,200 unplanned outages that led to the power problems.
The urgent call to Texans to save came just weeks after ERCOT said the state power grid could handle the expected record summer demand.
The week-long power concern arose in the week of June 14 as less electricity was available.
A total of 224 systems were offline this week. That means electricity that could supply more than 2 million households.
High temperatures led to an increased demand for air conditioning.
ERCOT reports that the largest failures have occurred in natural gas, coal and nuclear power plants.
In May, ERCOT said the risk of power outages this summer was less than 1%, but an energy expert says Texans should have a backup plan.
“On average, ERCOT expects us to get through August without too many problems. But for the consumer, if you have some kind of critical load like life support machines at home then you might want to consider some kind of backup generation, “said Ed Hirs, Energy Expert from the University of Houston.
Governor Greg Abbott called on the Public Utility Commission and ERCOT to come up with plans for better maintenance and development of additional natural gas, coal and nuclear power plant capacity. It’s part of an effort to shore up the state’s power grid.
There have been no new calls to save in the last month.
