The l1ghts are g01ng 0ut 1n Cal1f0rn1a aga1n, n0t because 0f st0rms 0r earthquakes, but because the electr1c system 1s be1ng 0perated at the edge 0f 1ts l1m1ts.

What appears t0 res1dents as sudden m1sf0rtune 1s 1n fact the pred1ctable result 0f years 0f p0l1cy ch01ces, 1nfrastructure delays, and 1ncent1ves that reward scarc1ty m0re than stab1l1ty.

In a state that pr1des 1tself 0n 1nn0vat10n and wealth, r0ll1ng black0uts are n0 l0nger rare emergenc1es.

They are bec0m1ng part 0f da1ly l1fe, and the c0nsequences are spread1ng acr0ss h0useh0lds, bus1nesses, h0sp1tals, and sch00ls.

The sequence 0ften beg1ns qu1etly.

On a warm M0nday m0rn1ng, 0ff1c1als gather f0r a gr1d read1ness br1ef1ng.

Cameras are 1nv1ted f0r a sh0rt sess10n 0f calm assurances.

The language 1s p0l1shed and c0nf1dent.

Operat0rs say c0nd1t10ns are be1ng m0n1t0red and that res0urces are ava1lable.

After rep0rters leave, the t0ne changes.

Beh1nd cl0sed d00rs, planners rev1ew a reserve marg1n that has fallen t0 a danger0usly th1n level.

Th1s marg1n ex1sts t0 pr0tect the system when equ1pment fa1ls 0r demand surges.

When 1t shr1nks t00 far, 0ne unexpected event can f0rce 0perat0rs t0 cut p0wer t0 ne1ghb0rh00ds t0 prevent a statew1de c0llapse.

By m1dday, the f1rst weakness appears.

A gas peaker plant, des1gned t0 start qu1ckly dur1ng per10ds 0f heavy demand, rep0rts a mechan1cal pr0blem.

The fa1lure d0es n0t destr0y the plant, but 1t rem0ves hundreds 0f megawatts that were scheduled t0 supp0rt the gr1d dur1ng the even1ng ramp, the m0ment when s0lar pr0duct10n falls wh1le h0useh0ld demand r1ses.

W1th1n h0urs, weather f0recasts w0rsen.

A1r c0nd1t10ners run c0nt1nu0usly.

Apartments w1th p00r 1nsulat10n trap warmth.

Fam1l1es wh0 cann0t aff0rd eff1c1ent c00l1ng systems face danger0us 1nd00r temperatures.

At the same t1me, electr1c1ty 1mp0rts fr0m ne1ghb0r1ng states bec0me unrel1able.

Cal1f0rn1a depends 0n 0uts1de p0wer dur1ng peak h0urs, yet surr0und1ng states are als0 c0p1ng w1th heat.

Each reg10n guards 1ts 0wn supply.

In the r1chest state 1n the nat10n, the ab1l1ty t0 keep l1ghts 0n depends 0n whether an0ther state has surplus energy t0 sell.

By late aftern00n, 0perat0rs 1ssue a c0nservat10n alert.

Res1dents are urged t0 ra1se therm0stats and av01d charg1ng dev1ces.

The message 1s framed as c1v1c duty, but the alert 1s als0 a c0nfess10n.

The system requ1res changes 1n pers0nal behav10r t0 surv1ve the even1ng.

When scarc1ty dr1ves pr1ces upward, flex1ble generat0rs earn large pr0f1ts.

N0 0ne welc0mes black0uts, but the structure rewards sh0rtage rather than abundance.

As the sun sets, s0lar 0utput decl1nes sharply.

Demand c0nt1nues t0 cl1mb as pe0ple arr1ve h0me, c00k d1nner, and turn 0n l1ghts.

Th1s pred1ctable m1smatch, kn0wn am0ng eng1neers as the even1ng ramp, 1s the m0st frag1le m0ment 0f the day.

When a transm1ss10n c0rr1d0r 0verheats and l0ses capac1ty, p0wer that ex1sts 1n 0ne reg10n cann0t reach ne1ghb0rh00ds that need 1t.

At seven 1n the even1ng, the f1rst 0rder f0r r0tat1ng 0utages g0es 0ut.

Bl0cks are selected t0 l0se p0wer f0r sh0rt 1ntervals, yet f0r the fam1l1es 1n th0se bl0cks, the 1nterrupt10n def1nes the n1ght.

The human 1mpact 1s 1mmed1ate.

In R1vers1de C0unty, a s1ngle m0ther returns fr0m w0rk t0 a dark apartment.

Gr0cer1es purchased 0n cred1t s1t 1n a warm1ng refr1gerat0r.

Agenc1es c0nvene meet1ngs and pr0m1se streaml1n1ng.

Yet the very ex1stence 0f emergency sh0rtcuts ra1ses an unc0mf0rtable quest10n.

If rules can be relaxed dur1ng cr1s1s, why were they n0t adjusted bef0re the cr1s1s arr1ved.

Perm1tt1ng f0r transm1ss10n upgrades takes years.

Env1r0nmental rev1ews stall pr0jects.
