A transformer took off Tuesday at Hoover Dam, one of the country's largest hydroelectric centers, generating a thick cloud of black smoke as well as flames that were promptly extinguished.
Nobody was hurt in the explosion near the base of the dam, a design wonder on the Colorado River that straddles the boundary of Arizona as well as Nevada. Power generated at Hoover Dam continued flowing to the 8 million individuals in Arizona, Nevada as well as Southern California who rely upon it, the Western Location Power Management claimed.
The root cause of the fire was under investigation and officials were functioning to establish the level of damage to the transformer, one of 15 at the complex that manages the voltages for power sent out to consumers.

" There is no threat to the power grid," claimed Jacklynn Gould, a regional supervisor for the U.S. Bureau of Recovery.
The fire stirred up around 10 a.m. and also was out within a half-hour, Gould said in a statement. It recorded the interest of visitors that stated they heard an alarm system audio as well as felt the ground grumble under them.
William Herro, 13, of San Francisco, was on a viewing bridge with his moms and dad when he saw the explosion and then listened to a "big boom."
" A ton of black smoke just blew up in the air. It looked nearly like a mushroom and after that, a fire followed," Herro stated. "I was actually shocked and I started recording."

The surge occurred on the apron of a building housing turbine that is somewhat downstream from the base of the dam, concerning 25 miles (40 kilometers) southeast of Las Vegas. Hoover Dam is just one of the highest concrete dams in the united state at 726 feet (221 meters). Each of its 17 generators can supply electricity to 100,000 families.
As lots of as 20,000 automobiles a day drive throughout the broad top of the dam, which is a National Historic Landmark and also is seen in films consisting of Transformers and also Fools Enter. A lot of drivers taking a trip between Arizona and Nevada use a bypass bridge high above the dam that opened in 2010.
The Bureau of Recovery has as well as runs the dam, powerhouses as well as generators. The power created at the website is transferred to a substation where it's marketed with the Western Area Power Management.
Hoover Dam is taken into consideration as a baseload source of power, suggesting it can react quickly to the need for added power on the grid or dial back supply.
The fire triggered an alert at the Western Area Power Management's nerve center in Phoenix. Spokesman Lisa Meiman claimed while the loss of a transformer or other devices on hydropower centers can put pressure on a grid, "no single resource is indispensable to the wellness of the power grid."
The management markets power from 57 government hydroelectric centers. Hoover Dam and Glen Canyon Dam upstream on the Arizona-Utah border are amongst the biggest, Meiman claimed.
Hydropower from those dams has been threatened recently by the decreasing levels of Lake Mead as well as Lake Powell, the two largest human-made tanks in the united state that hold water from the Colorado River.
Federal officials have actually done something about it in
recent times to prop up the lakes to protect the dams' capability to create
power as well as maintain water streaming to the Western states and also Mexico
that count on it. Drought, as well as climate change, have actually sunk the
lakes to their lowest levels in decades.
