TVA Will Improve Its Power Grid By $15 Billion Over Next 3-Years

TVA-Power-Grid

TVA’s load growth demand forecasted is expecting over a 30% increase in power demand within the next decade. Like other utilities trending away from fossil fuel power generation due to stringent carbon emission regulations, TVA is retiring their coal-powered plants and replacing with cleaner energy generation and renewable resources.

The trend of moving away from older fossil fuel technology to cleaner generation systems is very costly. TVA recognizes this and has approved moving forward with capital expenditures of $15 billion that it will invest over the next 3 years by performing system reliability upgrades and transition into cleaner energy supply.

With the increases in power generation retirements in both coal powered and nuclear energy plants, presents major reliability concerns to the electric infrastructure. There is over “83 GW of fossil fuel and nuclear generation” in planned retirements over the next decade that could wreak havoc on the nations power system.

NERC indicated in their “Long-Term Reliability Assessment” that this “creates blackout risks for most of the United States.”

3D CAD Modeling Substation Design

Substation-3D

By 3 Phase Associates:

Substations can be modelled in three-dimensions, allowing customers to see full scale in isometric views, or any views relative to positioning that they would not have had before with traditional 2D designs. Proper construction of electrical equipment in most 3D software also allows for efficient go-by production, as elements can be plugged in or removed in minutes, and entire substations can be remodeled according to revisions or to create whole new designs.

The ability to change the virtual materials of 3D models also allows for consistent and accurate representation of the substation. Instead of having a matte, grey mass in the shape of a transformer, circuit breaker, switches, concrete foundations, steel structures, insulators, and copper connection points can be expressed with proper physical dimensions of density, mass, etc., and includes appropriate colors that anyone who observes real-life substations can recognize.

Two 230kV Power Delivery Substations in NC Damaged by Gunfire

NC-Substations

By MarketWatch:

A criminal act is being investigated by the local authorities and the FBI that caused major substation damage to its power transformers and other equipment. This criminal act occurred sometime on Saturday night, Dec 3, 2022, in Moore County, NC.

The repairs could take weeks while several customers will remain without power. Crews will be working around the clock in order to replace the damaged equipment and to restore the power outages.

“Andrew Wilkins, a conservation advocate who grew up in Moore County, was driving Saturday night from Washington to his parents’ small farm in Whispering Pines when he noticed all the street lights were out in the county seat of Carthage. He arrived to a ‘pitch black street’ and little information about the cause or scope of the blackout. ‘When the power was cut, the flow of information was cut too.’ ”

China Reveals World’s Biggest Offshore Wind Turbine

China-Wind-Turbine

By PowerMag:

“Two Chinese companies announced production of the largest offshore wind turbine built to date, a 16-MW unit developed by China Three Gorges (CTG) and Goldwind.

The groups on Nov. 24 showed off the turbine at a factory in Fujian province. The turbine has a 252-meter rotor diameter, with a 50,000-meter sweep area. The hub height is 146 meters.

Lei Mingshan, chairman of CTG, in a statement said, ‘the successful rollout of the 16-MW unit marks that my country’s wind power equipment industry has achieved a historic leap from ‘following’ to ‘running alongside’ and then to ‘leading’, creating the latest benchmark for the development of global offshore wind power equipment.’ ”
