Southern Finance Quick Review: The Motivation and Enlightenment of Large-scale Power Outages in Texas, USA

Original Title: Nancai Express: Motivation and Enlightenment of Large-scale Blackout in Texas

In recent days, many states in the United States have been hit by winter storms for many consecutive days. Among them, Texas, located in the southern United States, was the most devastated. On the evening of February 14, there was the lowest temperature in nearly 30 years.Extreme weather has caused oil wells to freeze and natural gas power generation is reduced; turbines freeze and wind power generation is reduced; at the same time, power demand has risen sharply, causing supply to fall short of demand, forcing the entire Texas grid to implementshort termRotating power outages.Under the extreme imbalance of supply and demand, Texas electricity prices soared wildly, once rising to 10,000USD/MWh, equivalent to 200 times the local usual electricity price.

TexasPower IndustrymarketReform began in 1995, and successively opened upWholesale marketSpot market, The retail market on the electricity sales side, and the node market replaces itRegional market, Theoretically improve market efficiency.

However, in addition to physical reasons such as freezing of units caused by extreme weather, the large-scale blackout has certain market reasons. On the one hand, due to market cyclicality, the peak of power consumption in Texas is usually summer, and February is the time for most gas generators in Texas to be shut down for maintenance or shutdown, even if the local power system operator mandates that gas generators be turned on for power supply. It is also faced with operational risks caused by “cold start” and abandonment of maintenance.On the other hand, as the temperature plummeted, natural gaspriceIs also high, leading toenterprisePower generationcostRising, the willingness to generate electricity falls.Of course, there are also opinions that it is precisely becauseMarket reformThe extremely high electricity price generated makes the best use of scarce resources, curbs the further demand for electricity by enterprise users, and prevents the gap between electricity supply and demand from further increasing.

The top priority for Texas electric power system operators is to find a way to enable gas-fired units to generate electricity normally in such extreme cold weather, and at the same time improve early warning capabilities, so that peak-shaving generators can be prepared for power generation in advance to ensure the marketsupply.In addition, you need to adjustMarket mechanism, Through considerable economic benefitsexcitationPower generationthe companyMore peak-shaving generator sets will be added and repaired to cope with more extreme weather conditions brought about by future climate change. In the future, system operators also need to be cautious about the development of renewable energy and large-scale storage batteries to avoid similar large-scale downtime due to climate reasons.

  This historic storm reminds people of diverse fuel supplies, high-quality transmission infrastructure, and reliable grid operators and electricitysupplierEffective coordination between them is essential.

Obviously, the European and American power systems are highly market-oriented, which means that power companiesprofitMaximization is firstaimsTherefore, the supply of electricity is severely oriented by price, which increases public risks to a certain extent. So, if a region in China encounters a similar cold wave, how will it respond?China’s power system is fundamentally different from traditional developed countries such as Europe and the United States: China is stillPower IndustryDuring the market-oriented reform process, most power generation companiesState-owned enterprise, Its operating philosophy is to maximize benefits while maintaining public safety.Therefore, once a similar incident occurs, the grid company can force the deployment of power resources to the disaster-stricken area to protect people’s lives andpropertySafety.

Therefore, in China’s next electricity market reform, lessons should be learned, not only to pursue high efficiency, but also to ensure public safety: improve efficiency through market reforms, and at the same time strengthen supervision to ensure the order of production and life under extreme conditions. It is necessary to seek green development, but also to give play to the advantages of traditional energy: while vigorously developing new energy, avoid blindly removing the capacity of coal power units. Coal power units are still needed to maintain the stability of the grid before finding a solution to completely replace coal power units. run.Not only technological innovation but alsomechanismInnovation: On the one hand, the development of new technologies such as large-scale energy storage, carbon capture and storage is the futurePower IndustrySafe, green, and low-cost development brings confidence; on the other hand, we should study theIncentives, Making China’s power industry market-oriented reform more effective.
