Infrastructure & Smart Grid Advancements
In the age of burgeoning renewable energy sources and electrification, the quintessential power grid is undergoing a transformative overhaul. This transformation isn’t just about adding capacity; it’s about reimagining and reinventing the entire energy infrastructure to be more adaptive, responsive, and capable of handling the fluctuating dynamics of renewable energy and surging demand from sectors like electric transportation. The nexus of this transformation is the development of ‘smart grids’ and substantial enhancements in infrastructure flexibility.
The Imperative for a Flexible Electricity Grid
Evolving Energy Landscape: The increasing share of renewable energy, especially from intermittent sources like solar and wind, presents a fluctuating supply pattern. This mandates a grid that can dynamically respond to the variations in energy generation and demand.
Rising Demands from Electrification: As the world leans heavily into electrification, particularly with the EV surge, there will be new patterns of demand—both in volume and in timing—that grids will need to accommodate.
Quadrupling Flexibility by 2050: The report underscores the urgency, emphasizing the need to increase electricity system flexibility fourfold by 2050. This entails a mix of technological, policy, and infrastructural shifts.
Spearheading Investments in Grid Infrastructure
