Power blackout forces Texas to relook into equipment winterizing rules, says GlobalData
Due to a rare deep freeze in the US state of Texas, the power demand has increased immensely. With the residents staying home amid the strong winter storm, the usage of heating appliances has amplified. However, frozen wind turbines and limited gas supplies have hampered the power generation in the state resulting in power outage. Nevertheless, with the state committing to the addition of renewable energy installations (associated with intermittent supply), it is expected to relook and have mandatory rules for power generators on equipment winterizing so that such kind of power outages do not reoccur, says GlobalData, a leading data and analytics company.
As many generating units have been tripping offline, the immediate requirement was to address the demand-supply mismatch. As a result, the state’s electric grid operator, Electric Reliability Council of Texas (ERCOT) began implementing rolling blackouts in the state.
Texas is the largest contributor to the US electrical supplies. As per GlobalData, the state contributes 11% to the cumulative installations of the country. At the end of 2020, the cumulative installations in Texas was 143,527 MW. These installations were mainly driven by gas-fired stations and wind power plants.
Mohit Prasad, Project Manager at GlobalData, comments: “Electricity generating power plants are not properly winterizing their equipment. Winterizing equipment is making sure that the equipment deployed within power plants can sustain the extended periods of below-freezing temperatures. Additional costs are associated for winterizing equipment.
“Texas is one of the hotter states in the US and the electricity generators are mainly prepared for the heat. To avoid the additional cost, the generators generally skip the winterizing equipment. The deep freeze winter this year in Texas has made these equipments to stop working thereby making power plants tripping offline resulting in outages.”
As per GlobalData, Texas has installed 7.6 GW of solar PV installations at the end of 2020. This is expected to increase at a compound annual growth rate (CAGR) of 17.3% until 2030 and reach 38 GW. Similarly the wind sector in the state is expected to grow at a CAGR of 5.3% during 2020-2030 and reach 54 GW at the end of 2030.
Prasad concludes: “With the Biden administration setting a goal of eliminating pollution from fossil fuel in the power sector by 2035 and becoming carbon neutral by 2050, a push in renewable energy sector can be witnessed. Installation of more wind and solar PV plants can be seen.”
