'Red alert': Lake Mead falls to lowest water level since Hoover Dam's construction in 1930s

  'Red alert': Lake Mead falls to lowest water level since Hoover Dam's construction in 1930s Lake Mead declined to its lowest level since Hoover Dam's construction in the 1930s. It's a new milestone for the water-starved Colorado River.The reservoir near Las Vegas holds water for cities, farms and tribal lands in Arizona, Nevada, California and Mexico. Years of unrelenting drought and temperatures pushed higher by climate change are shrinking the flow into the lake, contributing to the large mismatch between the demands for water and the Colorado’s diminishing supply.

(CNN) Water in a key California reservoir will fall so low this summer that its hydroelectric power plant will be forced to shut down for the first time, officials said Thursday, straining the state's already-taxed electric grid. An unrelenting drought and record heat have pushed the water supply at Northern California's Lake Oroville to deplete to "alarming levels," which will likely force the first-ever closure of the Edward Hyatt Power Plant since it opened in 1967, California Department of Water Resources spokesperson Lindsay Buckley told CNN.

The most common type of hydroelectric power plant is an impoundment facility. An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. Facilities range in size from large power plants that supply many consumers with electricity to small and micro plants that individuals operate for their own energy needs or to sell power to utilities.

An unrelenting drought and record heat, both worsened by the changing climate, have pushed the water supply at Northern California's Lake Oroville to deplete rapidly. As a result of the "alarming levels," officials will likely be forced to close the Edward Hyatt Power Plant for the first time since it opened in 1967, California Energy Commission spokesperson Lindsay Buckley told CNN.

Operation - Generating Power (Electricity) Water flows from the upper reservoir, through the penstock, and to the Francis turbine. As the water passes over the Francis runner blades, a pressure differential is created that causes torque (rotary force ) to be applied to the runner. Many thermal power plants (coal fired, gas fired etc.) cannot increase or reduce their MW output quickly because this would place large thermal stresses on the power plant components ( water tube boiler, piping etc.). For this reason, thermal power plants produce almost as much power at night, as they do during the day.

The water in Lake Oroville — the state's second largest reservoir — is pumped through underground facilities to generate electricity, which can power up to 800,000 homes when operating at full capacity.

While the water level in the reservoir is currently hovering around 700 feet above sea level, if it continues to fall at the currently projected rate to 640 feet there will not be enough water to continue operating the Hyatt plant in two to three months, coinciding with the typical peak of the summer heat and wildfire season.

"If lake levels fall below those elevations later this summer, DWR will, for the first time, cease generation at the Hyatt power plant due to lack of sufficient water to turn the plant's electrical generation turbines," said Liza Whitmore, Public Information Officer of DWR's Oroville Field Division.

California and nearly a dozen other states want companies to reveal the financial risks of the climate crisis

As severe drought takes hold in California, firefighters are on high alert with risk of wildfire increasing. According to the U.S. Drought Monitor, 16 percent of California is in exceptional drought, the most severe level of dryness.

The state Department of Water Resources does not expect to use the spillway anytime soon, but says it is preparing to have the new structure cleared if Lake Oroville reaches 780 feet elevation. It will be another couple of weeks before the water level makes its way all the way to the top, where the emergency spillway will be used if that happens. Of course, DWR may increase releases, so that may not happen. Photo showing the elevations and placements of the gates and emergency spillway. h/t to Twitter via Rob Carlmark‏ @rcarlmark.

A small-capacity transmission network (microgrid) without inertial force has difficulties for converging short-term electric power fluctuations. Consequently, the frequency of transmission on such networks frequently diverges. Therefore, the electric power fluctuation due to cyclic fluctuation of an interconnected system of clean and renewable power sources (namely a solid oxide fuel cell (SOFC)-hydraulic generator, photovoltaics, and a wind-power generator) is investigated by numerical analysis

The announcement came as California Gov. Gavin Newsom declared a statewide heat wave emergency Thursday, with record setting temperatures and increased electricity use adding pressure to the grid.

"Amid a major heat wave that is stressing energy grids in states across the western United States, Governor Gavin Newsom today signed an emergency proclamation to free up additional energy capacity," Newsom's office said in a press release.

The governor's declaration, citing "extreme peril" to the safety residents due to the heat wave, suspends permitting requirements to allow the immediate use of back-up power generators to help alleviate stress on the state's energy grid.

California energy grid officials have called on residents to reduce power through Friday, especially during the evenings when electricity use is at its peak. Scaling back on using power during this peak time of the day will help avoid unneeded rolling power outages and damaged power lines, state officials previously said.

California's vegetation is at greater risk from wildfires because of record drying

In the Los Angeles area, moisture levels in vegetation have fallen to lows not seen since 2016, when the region was in the grip of "exceptional drought," the most severe level of dryness, according to Los Angeles Fire Department spokesperson Erik Scott.

This power plant plays an important role to protect our fossil fuel which is limited, because the generated electricity in hydro power station is the use of water which is renewable source of energy and available in lots of amount without any cost. The big advantage of hydro power is the water which the main stuff to produce electricity in hydro power plant is free, it not contain any type of pollution and after generated electricity the price of electricity is

As of 2018, hydro-power plants generated around 13% of the state's electricity. Hyatt power plant is the fourth largest hydroelectric energy producer statewide, according to the state's energy commission. Due to the already low water supply at Lake Oroville, the plant's output has been reduced to 20% of its total capacity and officials have relied on other facilities to avoid major power interruptions to homes and businesses, Whitmore said.

A similar situation was playing out at the Hoover Dam, which forms Lake Mead, the United States' largest reservoir and produces enough electricity for nearly 8 million Americans, where record-low water levels have reduced energy capacity by roughly 25 percent.

A hydroelectric plant downstream of the Hyatt facility in California will also operate at reduced levels this summer despite increased power demands during the typical summer peak, Whitmore said.

In addition to encouraging power-saving measures, officials statewide are urging Californians to reduce their water consumption as much as possible during the hot summer months ahead. They recommend curtailing water use by taking shorter showers, fixing leaks at home, planting drought-tolerant trees, and reduce watering home landscapes. Some officials in Northern California have already taken a stricter approach by declaring a water shortage emergency and issuing mandatory water restrictions that are punishable by fines for noncompliance.

"Water is a precious and limited resource, especially in drought-prone California where the next dry period could be right around the corner," the state's water resources department said. "As a result, water conservation and the efficient use of California's water supply are major priorities."
