Morte. Trionfo della Morte. Palermo. 001

Il problema non è il prezzo. Il problema è che sono introvabili.

Non è nemmeno problema di speculazione o che nessuno voglia vendere.

Ripetiamo per chiarezza.

Le industrie elettriche americane hanno scorte minime di combustibili e pezzi di ricambio, introvabili a qualsiasi prezzo si voglia. Come l’acqua in un deserto arido. Prepariamoci a giganteschi blackout.

Le compagnie elettriche statunitensi stanno affrontando una crisi di approvvigionamento che potrebbe ostacolare la loro capacità di tenere le luci accese mentre la nazione si avvia verso il caldo dell’estate e il picco della stagione degli uragani.

L’utilizzo di energia elettrica da parte dei consumatori dovrebbe raggiungere i massimi storici quest’estate, il che potrebbe mettere a dura prova le reti elettriche in un momento in cui le agenzie federali avvertono che il clima potrebbe creare problemi di affidabilità.

I servizi di pubblica utilità avvertono che le attrezzature sono limitate, il che potrebbe ostacolare gli sforzi per ripristinare l’energia elettrica durante le interruzioni.

Inoltre, è sempre più difficile ricostruire le scorte di gas naturale per il prossimo inverno, dato che i produttori di energia elettrica bruciano quantità record di gas dopo la chiusura di decine di impianti a carbone negli ultimi anni e l’estrema siccità riduce le forniture di energia idroelettrica in molti Stati occidentali

“I sempre più frequenti colpi di freddo, le ondate di calore, la siccità e le grandi tempeste continuano a mettere a dura prova la capacità dell’infrastruttura elettrica nazionale di fornire ai consumatori energia affidabile e a prezzi accessibili.

Non si vuole esaurire le proprie scorte perché non si sa quando arriverà la tempesta, ma si sa che sta arrivando

Alcune società di servizi si trovano ad affrontare tempi di attesa di oltre un anno per i componenti dei trasformatori.

L’estate è appena iniziata, ma quest’anno il clima negli Stati Uniti è già stato più caldo del 21% rispetto alla norma trentennale.

Se ci sono giorni consecutivi di caldo a 100 gradi, i trasformatori a palo iniziano a scoppiare come i Rice Krispies e non avremmo la scorta necessaria per sostituirli.

Inoltre, è più difficile ricostruire le scorte di gas naturale per il prossimo inverno, dato che i produttori di energia elettrica bruciano quantità record di gas dopo la chiusura di decine di impianti a carbone negli ultimi anni.

U.S. power companies face supply-chain crisis this summer

June 29 (Reuters) – U.S. power companies are facing supply crunches that may hamper their ability to keep the lights on as the nation heads into the heat of summer and the peak hurricane season.

Extreme weather events such as storms, wildfires and drought are becoming more common in the United States. Consumer power use is expected to hit all-time highs this summer, which could strain electric grids at a time when federal agencies are warning the weather could pose reliability issues.

Utilities are warning of supply constraints for equipment, which could hamper efforts to restore power during outages. They are also having a tougher time rebuilding natural gas stockpiles for next winter as power generators burn record amounts of gas following the shutdown of dozens of coal plants in recent years and extreme drought cuts hydropower supplies in many Western states.

“Increasingly frequent cold snaps, heat waves, drought and major storms continue to challenge the ability of our nation’s electric infrastructure to deliver reliable affordable energy to consumers,” Richard Glick, chairman of the U.S. Federal Energy Regulatory Commission (FERC), said earlier this month.

Federal agencies responsible for power reliability like FERC have warned that grids in the western half of the country could face reliability issues this summer as consumers crank up air conditioners to escape the heat

Some utilities have already experienced problems due to the heat. Texas’ grid operator, the Electric Reliability Council of Texas (ERCOT), was forced to urge customers to conserve energy after several plants shut unexpectedly during an early heat wave in mid-May.  

In mid-June, Ohio-based American Electric Power Co imposed rolling outages during a heat wave after a storm damaged transmission lines and knocked out power to over 200,000 homes and businesses.

The U.S. Midwest faces the most severe risk because demand is rising while nuclear and coal power supplies have declined

The Midcontinent Independent System Operator (MISO), which operates the grid from Minnesota to Louisiana, warned that parts of its coverage area are at increased risk of temporary outages to preserve the integrity of the grid.

Supply-chain issues have already delayed the construction of renewable energy projects across the country. Those renewable delays coupled with tight power in the Midwest prompted Wisconsin’s WEC Energy Group Inc and Indiana’s NiSource Inc to delay planned coal plant shutdowns in recent months.

                         BRACING FOR SUPPLY SHORTAGES

Utility operators are conserving their inventory of parts and equipment as they plan for severe storms. Over the last several months, that means operators have been getting creative.

“We’re doing a lot more splicing, putting cables together, instead of laying new cable because we’re trying to maintain our new cable for inventory when we need it,” Nick Akins, chief executive of AEP, said at the CERAWeek energy conference in March.

Transformers, which often sit on top of electrical poles and convert high-voltage energy to the power used in homes, are in short supply.

New Jersey-based Public Service Enterprise Group Inc (PSEG) Chief Executive Ralph Izzo told Reuters the company has had to look at alternate supply options for low voltage transformers.

“You don’t want to deplete your inventory because you don’t know when that storm is coming, but you know it’s coming,” Izzo said.

Some utilities are facing waiting times of more than a year for transformer parts, the National Rural Electric Cooperative Association and the American Public Power Association told U.S. Energy Secretary Jennifer Granholm in a May letter.

Summer is just starting, but U.S. weather so far this year has already been about 21% warmer than the 30-year norm, according to data provider Refinitiv.

“If we have successive days of 100-degree-heat, those pole top transformers, they start popping like Rice Krispies, and we would not have the supply stack to replace them,” Izzo said.
