A recent study from the Princeton Andlinger Center concluded that the grid needs to double by 2035 and triple by 2050 to support the required renewable integration and load growth from electrification. The scale of growth and short timeframe is incompatible with traditional capital-intensive methods of expanding transmission capacity, which takes 5-10 years. This is a discussion of a new era of grid infrastructure investment - one which leverages advanced sensors, batteries, analytics, and electronics technologies to increase the capacity, flexibility, and resilience of the grid we already have.
