Base Load Power Plants
“Do some power plants require a minimum supply of energy?”
Power plants kept the infrastructure of the old energy paradigm running. And many of these required a constant load to run, giving the name Base Load Power Plants. These plants would only be turned off for maintenance or upgrades. Examples include nuclear plants, coal-fired power plants, and tidal power plants.
India’s Regional Grids
“How is India’s national grid divided?”
India’s national grid is a modern engineering marvel that is able to keep electricity to the whole country flowing. But it rests on top of five Reginal Grids which power the North, South, West, East, and Northeast of the country.

India’s National Power Grid
“What connects all of India’s electricity sector together?”
India is one of the largest countries in the world and is about to become the most populous as well. And it must find a way to meet the electricity needs of its citizens. This is done through a National Power Grid, which connects 5 regional grids through high voltage electricity. This allows for power trading and stabilization when necessary.

“How can we hook up two asynchronous power connections?”
Different power grids might operate at different frequencies. And they might also cover different geographic regions that offer different but useful resources. They can be hooked up together at an HVDC substation using something called a Back-to-back Connection.
“How is rock and soil material transported from one part of the Earth’s surface to another?”
Weathering can break down rocks and soils on the Earth into smaller components. Once they are small enough, they can be easily scooped up by natural Earth fluids such as wind and rainwater runoff. This process is known as Erosion and is one of the most fundamental aspects of geology.
Plant Capacity Factor
“How can we determine the potential used by a power-plant during a given period of time?”
Power plants are capable of generating a certain amount of energy. But only so much of it actually gets used. The ratio of energy used/potential energy is known as the Plant Capacity Factor. A simple way to conceive of the plant capacity factor is to think about the amount you can study in an hour compared to how much you study. Although you might be able to study a lot in an hour, the amount you actually study determines your efficiency!

“How are rocks broken down over time?”
Thanks to entropy, nothing stays permanent over time. This is very true on the geological scale. Over time, rocks on the Earth’s surface will be broken down by contact with the Earth’s Atmosphere, Water, and Biological Organisms. This is known as Weathering and is one of the primary changers of the Earth’s surface.
