Spreading the power load could help to defer or avoid increasing demand capacity. Upgrades to accommodate growing demand could cost tens of billions of dollars, EECA chief executive Marco Pelenur said. The electricity network is built to handle peak demand, which only occurs a few times a day for short intervals. "This [analysis] shows we could save billions as a country just by moving when we use power." Rooftop solar and batteries could help shift household demand, but much lower-cost measures - that would also save households money - were also available.
