Aging grid dilemma:
maintenance and reliability
In the USA, the average age of the grid transmission lines and transformers is forty years old, with more than a quarter of the grid fifty years old or older. Most of the grid infrastructure is built above ground – making it susceptible to extreme weather. In the summer, power outages increase as heatwaves and storms wreak havoc on the power grid resulting in Power outages. To simply upgrade this infrastructure and maintain the status quo would require an investment of more than seven hundred billion dollars, over the next 30 years.
