At the large scale, electricity cannot be effectively stored with current technology
3.At the large scale, electricity cannot be effectively stored with current technology. In other words, the electricity generated and transmitted over the power lines needs to match the electricity that is being used. ISO New England is an organization that carefully predicts how much energy will be used in the New England power grid during every hour of every day. They then communicate with energy generating companies (nuclear, solar, gas-burning power plants, etc.) to supply the most economic electricity to the grid at a certain time.
