Industrial Reserve Plants are facilities designed to provide backup power during peak demand or emergencies. They can quickly generate electricity to support the grid when regular power sources are insufficient. These plants often use various energy sources, including natural gas, coal, or renewable energy. These plants play a crucial role in maintaining the reliability of the electrical grid. By being on standby, they help prevent blackouts and ensure that essential services, such as hospitals and emergency services, continue to operate smoothly during power shortages.
