At the intersection of these lanes is a place where ideas on finance, technology and policy are shared and debated. That intersection is Interchange Recharged. Your host is Sylvia Leyva Martinez, principal analyst and research director at Wood Mackenzie. When Sylvia isn't tracking the technologies and markets driving the build-out of renewable power, she's speaking with visionaries, entrepreneurs, policy-makers and energy analysts to explore the newest developments in renewable technology, explain the ideas on global energy policy that could accelerate the energy transition, and identify new funding and financial models that could solve the biggest challenges we face on the way to net zero. Sylvia and her guests bring you data and forecasts on clean technology, climate science, and offer predictions on the build out of utility-scale projects and the future of green finance. What does the surge in data-centre demand mean for the grid, and who pays for it? What's happening in global EV adoption and development? What's the forecast for solar, one of the major succ…","last_synced_at":"2026-09-16T02:19:58.805362+00:00","page_url":"https://stenobird.com/podcast/interchange-recharged-1117793"},"episode":{"title":"The grid's immune system is retiring: Synchronous condensers, AI data centers and the physics gap that software alone can't close","slug":"the-grid-s-immune-system-is-retiring-synchronous-condensers-ai-data-centers-and-the-physics-gap-that-software-alone-can-t-close","published_at":"2026-05-19T11:00:00+00:00","page_url":"https://stenobird.com/podcast/interchange-recharged-1117793/the-grid-s-immune-system-is-retiring-synchronous-condensers-ai-data-centers-and-the-physics-gap-that-software-alone-can-t-close","show_page_url":"https://stenobird.com/podcast/interchange-recharged-1117793","url":"https://dts.podtrac.com/redirect.mp3/rss.art19.com/episodes/f334a8aa-6f93-4f1d-a50f-0af67280b7d1.mp3?rss_browser=BAhJIg90cmFuc2NyaWJyBjoGRVQ%3D--952c5701c84ad333c69d5faa668f8177091704f0","audio_url":"https://dts.podtrac.com/redirect.mp3/rss.art19.com/episodes/f334a8aa-6f93-4f1d-a50f-0af67280b7d1.mp3?rss_browser=BAhJIg90cmFuc2NyaWJyBjoGRVQ%3D--952c5701c84ad333c69d5faa668f8177091704f0","summary":"As coal and gas plants retire, the energy transition conversation focuses on replacing their generation capacity. What gets far less attention is the loss of the physical properties those machines provided for free: inertia that stabilises frequency, fault current that supports voltage during disturbances, and reactive power that regulates voltage across the network. These services come from the physics of enormous spinning rotors synchronised to the grid, responding instantaneously, without sensors, software or control loops. As inverter-based resources replace them, that mechanical immune system disappears, and a new, extreme stress test is arriving at the same time in the form of AI data centres whose loads can swing by hundreds of megawatts in a fraction of a second. Host Bridget van Dorsten is joined by Kristina Carlquist, General Manager of Synchronous Condensers at ABB, and Christian Payerl, Sales Manager of Synchronous Condensers at ABB, to unpack why a technology that has existed for as long as the grid itself is now experiencing a revival. Christian explains the three ancillary services the grid is losing, inertia, short-circuit current and reactive power, and why inverter-based generation does not replace them. Grid-forming batteries can be programmed to simulate inertia, but each charge-discharge cycle degrades lifetime, overload capacity is limited to microseconds, and the models needed for accurate grid simulation are often tied up in manufacturer IP. Synchronous condensers respond on physics alone, in both directions, with no degradation and no modelling uncertainty. The recent blackout in Spain illustrates what happens when that gap is left unfilled. Kristina walks through the commercial traction.
