Power generation and storage is the part of the energy industry that makes electricity and keeps some of it for later. Switch on a fan in your home and the electricity may come from a wind farm in Maharashtra, a solar park in Madhya Pradesh or a gas-fired power plant. India is adding wind and solar capacity faster than almost any other country.
This scene covers the equipment, and the software built into it. It has two zones. The first is power generation. It holds the wind turbine, the gas turbine, the solar panel, the solar inverter and the solar tracker. It also holds standby generators and AI that designs nuclear reactors. The second zone is energy storage. It holds the large batteries that store power and the electrolysers and fuel cells that store it as hydrogen.
Storage is needed because the weather does not follow demand. Solar panels produce most power at noon, but homes use most power in the evening. The grid must always keep the power put in equal to the power taken out, every second. If the two drift apart, the grid's frequency moves away from 50 hertz and equipment can switch off to protect itself. This rule is called grid balancing. A battery that charges at noon and discharges at 7 pm helps to keep that balance.
The customers for this equipment are mostly power producers, the companies that own power plants, and the state and central companies that run them. A homeowner is a customer too, when buying a rooftop solar system.
Equipment makers hire software engineers because this equipment now runs on software. A turbine has sensors and is watched from a control room far away. An inverter reports how much power it is producing. The maker also keeps servicing the machine for 20 or 30 years, which is a business called aftermarket service. Solar panels and batteries make direct current, so AC and DC conversion is part of nearly every product here.
