Texas has faced multiple power outages in recent years, including the 2021 power crisis, which saw electricity demand exceed 67.2 gigawatts, overwhelming the grid operator. This crisis was preceded by another major outage in 2011, caused by a blizzard that resulted in rolling blackouts across more than 75% of the state. These incidents have brought attention to the need for upgrades to Texas's electrical infrastructure, particularly in winterizing the systems to prevent future disruptions. The state's power grid is expected to face increasing demand, and the development of clean energy projects may be impacted by the rollback of tax credits, potentially slowing the transition to renewable energy sources.

What You'll Learn
The 2021 Texas power crisis
In February 2021, Texas experienced a major power crisis during three severe winter storms (known as Winter Storm Uri) that swept across the United States between February 10–11, 13–17, and 15–20. The storms triggered the worst energy infrastructure failure in Texas's history, causing power outages for over 4.5 million homes and businesses, some for several days. The crisis resulted in shortages of water, food, and heat, and led to at least 246 deaths, with some estimates as high as 702.
The crisis was caused by a combination of factors, including a lack of winterization of traditional power sources, particularly natural gas infrastructure, and, to a lesser extent, frozen wind turbines. Cold weather disrupted 22 gas processing plants two days before the blackouts began, and over the course of just four hours on February 15, 40% of the grid's capacity went offline. This led to a surge in electricity demand, exceeding what the grid operator had planned for in extreme winter weather. The Electric Reliability Council of Texas (ERCOT), which manages 90% of the state's power grid, was criticized for its poor preparation and decision-making during the storm.
In the aftermath of the crisis, there were investigations into the power outage to determine long-term solutions. Governor Greg Abbott declared that ERCOT reform was an emergency priority, and Congress launched an investigation into the power crisis by requesting documents relating to winter weather preparedness. The wholesale electric price was set at a high rate of $9,000/megawatt-hour during the crisis, resulting in large bills for customers with certain pricing plans. The total electricity costs on February 16 alone reached $10.3 billion.
To prevent similar crises in the future, there have been calls for upgrades to Texas's electrical infrastructure and winterization of power infrastructure. Governor Abbott signed two bills in June 2021 to address the state's power grid issues, and there have been proposals for regulations to ensure the gas industry is prepared for winter operations. However, the gas industry has resisted regulation, and there are concerns that Texas has not invested sufficiently in technologies for gas winterization.

The Federal Energy Regulatory Commission's recommendations
Texas has experienced multiple power outages in the past, including the 2021 power crisis, which left millions without power. The Federal Energy Regulatory Commission (FERC) has made several recommendations to prevent future power outages in Texas.
Firstly, FERC has emphasized the need for stronger mandatory electric reliability standards, particularly regarding generator cold weather-critical components and systems. FERC's final report on the February 2021 freeze highlighted that a combination of freezing and fuel issues caused the majority of unplanned generating unit outages. By protecting certain power plant components from icing and freezing, outages could be significantly reduced. FERC's recommendations include revisions to the NERC Reliability Standards related to generator winterization and improved gas-electric coordination.
Secondly, FERC has recommended upgrading Texas's electrical infrastructure to make it more resilient to extreme weather events. Following the 2011 Groundhog Day blizzard, which caused rolling blackouts across more than 75% of Texas, FERC reported that additional winterization of power infrastructure was necessary. However, these recommendations were not mandatory, and ERCOT's independence from FERC may have contributed to the lack of mandatory regulation.
Thirdly, FERC has suggested improving coordination between gas and electric sectors. The 2021 power crisis was exacerbated by gas supply issues, with 87% of unplanned generation outages due to fuel issues related to natural gas production and processing. FERC is investigating anomalies in the natural gas market and potential price manipulation by companies.
Additionally, FERC's recommendations include increasing the reserve margin of power capacity in Texas. A 2019 report by the North American Electric Reliability Corporation found that ERCOT had a low anticipated reserve margin, leaving Texas vulnerable to peak demand periods.
Finally, FERC has emphasized the importance of learning from past events and taking proactive measures to prevent future power outages. Texas politicians and regulators were warned after the 2011 storm about the need for winterizing power infrastructure, but these warnings were not adequately heeded. FERC's recommendations aim to ensure that Texas's power grid is better prepared for extreme weather events and that the necessary upgrades and improvements are implemented.

The ERCOT grid operator's role
The Electric Reliability Council of Texas (ERCOT) is an independent electricity grid operator that manages the power flow for around 90% of Texas. Historically, Texas has operated its grid separately from the rest of the United States, which has allowed ERCOT to avoid certain federal regulations. However, this separation also means that Texas has a limited ability to import electricity from other states during emergencies.
In the case of the 2021 Texas power crisis, ERCOT played a significant role. The crisis was caused by an extreme winter storm that resulted in a massive electricity generation failure, leaving more than 4.5 million homes without power. ERCOT implemented rolling blackouts to prevent a total grid collapse, but the state's electrical infrastructure was not adequately prepared for the extreme winter weather. Demand exceeded supply, and the grid came close to overloading and shutting down completely.
Following the 2011 Groundhog Day blizzard, which caused similar power outages, the Federal Energy Regulatory Commission recommended that Texas upgrade its electrical infrastructure to better withstand cold weather. However, these recommendations were not mandatory, and many were not implemented due to the associated costs. As a result, when the 2021 winter storm hit, ERCOT was once again unprepared for the extreme weather conditions.
In the aftermath of the 2021 power crisis, there were calls for ERCOT reform, and investigations were launched to determine long-term solutions. One such solution is the $360 million project to connect the ERCOT grid with the U.S. grid, creating a direct link to neighboring grids. This expansion aims to increase reliability, reduce power outages, and stabilize energy costs. By connecting to the national grid, Texas will be able to import electricity from other states during emergencies, providing a buffer to meet unexpected demand spikes.

The impact on customers
The impact of power outages on customers can be significant, as evidenced by the effects of the 2021 Texas power crisis. During this event, customers with pricing plans based on wholesale prices faced large bills, with some seeing charges of over $5,000 for five days of service during the storm. This was due to the wholesale electric price being set at $9,000/megawatt-hour, much higher than the typical $25/MWh. The high demand for electricity during the winter storm strained the electrical grid, resulting in rolling blackouts across more than 75% of the state. Many roads around Houston became impassable, and boil-water advisories were issued in several areas. The power outages also disrupted transportation and communication systems, affecting people's ability to travel and stay connected with loved ones.
In the aftermath of the power crisis, there were investigations into the causes of the outages and the resulting impact on customers. The Federal Energy Regulatory Commission had previously made recommendations for upgrading Texas's electrical infrastructure to prevent similar events, but these suggestions were not heeded due to the cost of winterizing the systems. The power crisis highlighted the need for more resilient and diversified energy infrastructure in Texas, especially as the state's demand for electricity continues to rise.
The Texas power crisis also brought to light the importance of regulating electricity prices during emergencies. The wholesale prices were kept artificially inflated at $9,000 for about four days, even after electricity demand dropped, which further exacerbated the financial burden on customers. The total electricity costs during the crisis were significant, with Texas spending $10.3 billion on February 16 alone, exceeding the total spending for the entire previous year.
To prevent similar customer impacts in the future, there have been calls for reforms and investments in Texas's energy sector. Governor Greg Abbott declared ERCOT reform as an emergency priority, and there have been discussions about the need for a more diverse generation portfolio to enhance grid resilience. Additionally, the state has seen a boom in wind and solar power, but the rollback of tax credits for renewable energy projects may hinder further development in this sector. The slowdowns in clean energy projects could impact electricity prices, as grid operators predict soaring electricity demand in the future.
Overall, the impact of power outages on customers can be far-reaching, affecting their finances, daily lives, and access to essential services. The Texas power crisis of 2021 served as a catalyst for discussions and potential reforms to enhance the resilience and affordability of the state's energy sector.

The future of Texas' electrical infrastructure
The future of Texas's electrical infrastructure is a pressing issue that has come to the fore following a series of power outages and crises. The state has historically relied on energy sources that are vulnerable to extreme weather events, such as the 2021 power crisis, which was caused by frozen power equipment during a severe winter storm.
To prevent similar events from occurring in the future, upgrades to the electrical infrastructure and winterization of power systems have been recommended. However, these suggestions have often been ignored due to the associated costs. As a result, Texas continues to face challenges in meeting the rising demand for electricity, especially during periods of extreme weather.
The state's electrical infrastructure is expected to face even greater strain in the coming years due to economic and population growth, as well as the emergence of new large electricity users, such as data centers. To address this, Texas has seen a boom in wind and solar power, with companies announcing over $128 billion in planned investments for clean energy facilities. These projects, however, are now at risk due to the Trump administration's rollback of tax credits, which has shortened the timeline for qualifying for these incentives.
To ensure a more resilient and sustainable future for Texas's electrical infrastructure, a diverse generation portfolio is necessary. This includes continued investment in renewable energy sources, such as wind and solar power, despite the challenges posed by changing tax credit policies. Additionally, mandatory regulation and winterization of power infrastructure are crucial to prevent weather-related outages, as recommended by the Federal Energy Regulatory Commission following the 2011 and 2021 power crises.
The state legislature has recognized the need for reform, with Governor Greg Abbott declaring ERCOT reform an emergency priority in 2021. However, the path forward remains uncertain, and the state must balance the costs of upgrading its electrical infrastructure with the potential consequences of failing to do so.
