The grid “is designed for the core components - supplying electricity - but we are definitely pushing it to its limits,” says Melissa Lott, Partner for energy technologies at Microsoft*. The electricity grid has been described as one of the greatest achievements of human civilisation, because of its complexity, scale, and essential role in our societies. But it’s been around for over century, and in some places its components are many decades old. Whatever you think about the future of energy, it seems clear that we need a modernized grid to meet the new challenges we are facing, including growing demand and increased reliance on variable renewables.  So how do we build the right things in the right places? Joining Melissa and host Ed Crooks is first-time Energy Gang guest Alice Jackson. She’s a VP of Grid Modeling at the think-tank and cleantech investment firm Breakthrough Energy*.  Alice shares how Breakthrough Energy is working to help develop a grid that will meet future needs, around the world. Among other work, they are building open-source, open-access tools for grid planners, to shorten the time needed to secure regulatory approvals and start building. With rising energy needs driven by data centers for AI and new gigafactories, and new types of load such as EV charging, the grid requires radically different system planning to meet demand.  On top of that, the physical infrastructure that makes up the grid is aging and badly in need of renewal in many developed countries. Alice, Ed and Melissa discuss the challenge of balancing the need to replace old and crumbling infrastructure with the need to scale up capacity to match demand.  The gang also assess a recent paper from the US Department of Energy, which warns that “the status quo is unsustainable” for the nation’s grid. And they debate cutting-edge approaches that are being proposed to help boost flexibility in electricity systems and minimise the need for more fossil fuel generation.  The US energy department report discussed in this episode can be found here: https://www.energy.gov/articles/department-energy-releases-report-evaluating-us-grid-reliability-and-security *Melissa and Alice are appearing in this episode in a personal capacity; their views do not necessarily represent those of Microsoft or Breakthrough Energy.
