With global energy demand at an all-time high, battery storage is evolving from a flexible filler into a critical grid resource. Success in this new era depends less on the hardware itself and more on the digital intelligence used to run it. By leveraging a digital layer to optimize the economics of battery assets, utilities are now rethinking BESS as a high-value, GW-scale engine for reliability and market participation.
To understand what this means on a practical level, we sat down with Brian Fellon, the Senior Vice President of Power Solutions at Xpansiv. He explains why battery energy storage systems are no longer an optional add-on but a critical backbone for grid operators. We also explore how utilities are moving from small-scale pilots to gigawatt-scale operations, the role of batteries in managing volatile demand from data centers, how real-time market participation demonstrates measurable value to regulators and ratepayers and much more.

As energy demand reaches historic levels, the utility industry needs to build a 21st-century grid while also keeping monthly bills affordable for the average family. What does it mean to do so on a practical level?
To find out, we connected with Exelon EVP and COO Mike Innocenzo. Drawing on a career that began as a field engineer, he explains why affordability has become the starting point for every conversation at Exelon. He shares how the company navigates the massive costs of data center integration and EV adoption while overseeing a $38 billion capital plan. We also explore the reality of hardening the grid, the regulatory innovations needed to streamline costs, how Exelon uses AI to protect their customer’s bottom line and much more.

The scale of energy demand in Northern California has reached a historic inflection point. With a 10 GW pipeline of data center demand—enough load to power more than 7.5 million homes—utility planners at Pacific Gas and Electric (PG&E) are navigating a high-stakes race against time, infrastructure limits, and the laws of physics.
To better understand how PG&E is turning these challenges into opportunities, we connected with two people who are doing exactly that for the company every single day. Austin Hastings is Vice President, Gas Engineering at PG&E while Mike Medeiros is Vice President, Strategic Commercial Solutions at PG&E.
