  • Beyond the Chip: Rewiring Data Center Supply Chains
    Feb 4 2026

    As AI drives a new wave of data center expansion, the focus is shifting from chips to the infrastructure that powers and cools them. Denser AI workloads are accelerating the move toward liquid cooling, higher-capacity electrical equipment and new power architectures, putting pressure on traditional supply chains and forcing rapid innovation across the ecosystem. So how is AI reshaping the hardware behind data centers, and what does it mean for the future of power, cooling and grid infrastructure?

    At the BloombergNEF Summit San Francisco, Mark Daly, BNEF’s head of technology and innovation, moderated a panel titled “Seeing Beyond the Chips: Innovations in Data Center Supply Chains.” This episode brings listeners that panel, which featured Steven Carlini, chief advocate for data centers and the AI energy management business unit, at Schneider Electric; Haroon Inam, the co-founder and chief executive officer of DG Matrix; Jill Macari, the chief financial officer of VEIR; and Angela Taylor, the chief of staff and head of strategy at LiquidStack.

  • How Co-Located Batteries Are Reshaping Solar’s Future
    Jan 29 2026

    After years of rapid expansion, the buildout of solar power is starting to slow. Capacity additions are set to dip slightly in 2026, the first decline since BloombergNEF began tracking the market. At the same time, the way solar is built is changing, with developers increasingly pairing projects with batteries to manage curtailment, share grid connections and boost revenues. So what does this new phase mean for solar, and how far can co-location carry the industry? On today’s show, Tom Rowands-Rees is joined by BNEF’s head of solar research, Lara Hayim, and analyst Cosmo van Steenis to discuss findings from the notes “4Q 2025 Global PV Market Outlook: First Ever Dip” and “Co-Located Storage Boosts Solar’s Business Case.”

    Complementary BNEF research on the trends driving the transition to a lower-carbon economy can be found at BNEF on the Bloomberg Terminal or on bnef.com

  • Power Grid Spending Surges But Capacity Still Lags
    Jan 22 2026

    Investment in power grids is rising fast. Worldwide, spending on this critical piece of infrastructure rose 17% last year. Yet higher outlays are not necessarily translating into new capacity on the ground. Aging assets, supply-chain constraints and the rollout of new technologies are slowing delivery, while connection queues for both generation and load are getting longer. With grids under pressure from all sides, what’s really holding expansion back, and what will it take to turn rising investment into real-world capacity? On today’s show, Tom Rowlands-Rees is joined by BloombergNEF’s head of grids research, Peter Wall, to discuss findings from his team’s note “Grid Investment Outlook 2025: Double-Digit Growth – Again.”
