Nearly half of Texas' installed wind power generation capacity has been offline because of frozen wind turbines in West Texas, according to Texas grid operators.
Wind farms across the state generate up to a combined 25,100 megawatts of energy. But unusually moist winter conditions in West Texas brought on by the weekend's freezing rain and historically low temperatures have iced many of those wind turbines to a halt.
As of Sunday morning, those iced turbines comprise 12,000 megawatts of Texas' installed wind generation capacity, although those West Texas turbines don't typically spin to their full generation capacity this time of year.
Fortunately for the Electric Reliability Council of Texas, which manages the state's electric grid, the storm's gusty winds are spinning the state's unfrozen coastal turbines at a higher rate than expected, helping to offset some of the power generation losses because of the icy conditions.
"This is a unique winter storm that's more widespread with lots of moisture in West Texas, where there's a lot of times not a lot of moisture," said Dan Woodfin, Senior Director of System Operations for the Electric Reliability Council of Texas. "It's certainly more than what we would typically assume."
Wind power has been the fastest-growing source of energy in Texas' power grid. In 2015 winder power generation supplied 11% of Texas' energy grid. Last year it supplied 23% and overtook coal as the system's second-largest source of energy after natural gas.
In Austin, wind power supplies roughly 19% of the city's energy demands, all of which is passed from producers to consumers across the state grid. The city began adding several megawatts of wind energy capacity to its renewable energy portfolio in the 1990s from both West Texas and Gulf Coast wind farms.
The frozen turbines come as low temperatures strain the state's power grid and force operators to call for immediate statewide conservation efforts, like unplugging non-essential appliances, turning down residential heaters and minimize use of electric lighting.
Electric demand is expected to exceed the state's previous winter-peak record set in January 2018 by 10,000 megawatts. And peak demand expected for Monday and Tuesday is forecasted to meet or exceed the state's summertime record for peak demand of 74,820 megawatts.
"Typically, the ERCOT system peaks in the summer because of the air conditioning load, but we're seeing forecasts of overall demand being that high in the next few days," Woodfin said.

Valaris Limited announced new contracts awarded subsequent to issuing the Company’s most recent fleet status report on February 21, 2023. Three-year contract with Petrobras for drillship VALARIS DS-8. The rig will be reactivated for this contract. The total contract value is approximately $500 million, including a $30 million mobilization fee. 100-day contract with a TotalEnergies affiliate for drillship VALARIS DS-12. The contract is expected to commence in second quarter 2023. 70-day contract with Beach Energy offshore New Zealand for heavy duty modern jackup VALARIS 107. The contract is expected to commence in third quarter 2023. The total contract value is approximately $26 million. President and Chief Executive Officer Anton Dibowitz said, “We are particularly pleased to have secured the award for preservation stacked drillship VALARIS DS-8, for a contract that is expected to generate a meaningful return over the firm contract term, and we remain focused on exercising our operational leverage in a disciplined manner. This most recent award represents the sixth contract awarded to one of our high-quality stacked floaters since mid-2021, and speaks volumes about our demonstrated track record of project execution when reactivating rigs.” Dibowitz added, “Following the reactivation of VALARIS DS-17 and DS-8, we will have ten floaters working across the golden triangle, including four drillships in Brazil, a market where we expect to see continued growth over the next several years.” Updated Guidance As a result of the contract awarded to VALARIS DS-8, which will require the rig to be reactivated from preservation stack, we are updating our first quarter 2023 and full-year 2023 guidance provided on our fourth quarter 2022 conference call on February 21, 2023. First Quarter 2023 Contract drilling expense is expected to increase by approximately $5 million to $385 million to $395 million. Adjusted EBITDA is expected to decrease by approximately $5 million to negative $5 million to breakeven. Adjusted EBITDAR, which adds back one-time reactivation expense, is expected to be $25 million to $30 million, unchanged from the guidance provided on our fourth quarter 2022 conference call. Full-Year 2023 Revenues are anticipated to be $1.8 billion to $1.9 billion, unchanged from the guidance provided on our fourth quarter 2022 conference call. Contract drilling expense is expected to increase by approximately $60 million to $1.49 billion to $1.59 billion. Adjusted EBITDA is expected to decrease by approximately $60 million to $180 million to $220 million. Adjusted EBITDAR, which adds back one-time reactivation expense, is expected to be $280 million to $320 million, unchanged from the guidance provided on our fourth quarter 2022 conference call. Capital expenditures are expected to increase by $60 million to $320 million to $360 million.

Semisub rig owner Dolphin Drilling has inked a new contract with Peak Petroleum in Nigeria for its 1974-built Blackford Dolphin. The firm contract, which follows the letter of award in January, gives the Euronext Growth-listed owner of three rigs the potential to extend the unit’s backlog by a minimum of 120 days and up to 485 days. The deal adds to and will be a direct continuation of the previously announced 12-month contract with General Hydrocarbon Limited (GHL). Øystein Stray Spetalen-backed company said the effective dayrate associated with the minimum firm period of the contract is $325,000, including the mobilisation fee. “The final award of the contract for Blackford Dolphin shows the opportunities in Nigeria at a strong dayrate, in addition to building on the backlog for the rig. It also underlines the attractiveness of our assets, and we look forward to returning to revenue-generating operations in 2023,” noted Bjørnar Iversen, CEO of Dolphin Drilling.
