With Great Power

Audrey Zibelman’s first job as a trial lawyer in a male-dominated firm in Minneapolis wasn’t a good fit. So she moved to the state’s attorney general office, a place known for being more supportive of working mothers like her. But she never would have guessed that the shift would lead her into the power sector. But it did.

After a dynamic career as a utility executive, regulator, and founder, Audrey now serves  on corporate boards and in advisory roles where she advocates for designing responsive power systems and focusing on consumers’ needs. 

This week on With Great Power, Audrey Zibelman talks about lessons learned and walks Brad Langley through the distributed energy resource (DER) policy and research tools she recently helped develop as part of the Distributed Energy Resources Initiative Advisory Council for the Pew Charitable Trusts. Those tools include a state-by-state policy explorer that tracks how states are advancing DERs, as well as a DER policy playbook.

In 2007, Apple released its first iPhone. That same year, Seth Frader-Thompson co-founded EnergyHub, planning to leverage smartphones to help consumers save energy.  

But over time, the startup realized there was actually a bigger opportunity: helping  utilities centralize and control the growing list of distributed energy resources, like smart thermostats and rooftop solar, that their customers were installing. In fact, EnergyHub was so early to the build-out of virtual power plants and distributed energy resource management systems that Seth has been called the OG of DERMS.

This week on With Great Power, Seth tells Brad Langley what EnergyHub has learned about how virtual power plants mature – and the test they’ve developed to track maturity – as well as how EnergyHub plans to meet its goal of bringing 100 gigawatts of dispatchable flexibility online by 2035.

In 2019, when Julia Hoos moved to Houston for a role with Boston Consulting Group, she had no interest in the energy industry. For one thing, it was — and largely remains — a boy’s club. For another, energy just didn’t excite her.

But as she started learning about the energy transition, Julia became curious. Before long, she was crunching numbers for an oil and gas client looking to understand how California’s zero-emissions vehicle mandate would impact demand for its fuel products. Then, in 2022, Julia joined power market analytics firm Aurora Energy Research, where she focuses on the eastern U.S. and the PJM power market.

This week on With Great Power, Julia talks to Brad Langley about the pressures that PJM is facing, and its reform efforts. They also discuss how demand flexibility could support more data centers without adding new generation, and how utilities are using large load tariffs to manage costs and grid reliability.

Growing up in Silicon Valley, Varun Sivaram didn’t look to Elon Musk or Sergey Brin to learn about success stories. He looked to his dad, a material scientist who immigrated from India. 

But Varun’s own dreams of pursuing a career in technology took a circuitous path. His physics lab at Oxford discovered a promising new solar material, but when he emerged from graduate school in 2012, it was no time to launch a renewables startup. After a successful early career pursuing his other love, foreign relations, he pivoted to tech. In 2024, Varun founded Emerald AI, which helps data centers adjust their workloads to use energy more efficiently.

This week on With Great Power, Varun explains why he thinks AI can help save the grid. Varun and Brad talk about the demonstration pilots Emerald AI has completed and Varun’s vision for a massive AI factory the company is helping to build, in Virginia.

From his early days as a paper boy and eagle scout to his time as a naval officer decades later, Casey Kirkpatrick has always believed in service. Today, after more than 25 years with the energy giant National Grid, he’s still serving.  

Casey directs National Grid’s strategic engineering team, where he focuses on an emerging threat that most of its east coast ratepayers don’t think much about: wildfires. To get ahead of that growing risk, National Grid has partnered with Rhizome, a company that helps utilities understand their wildfire vulnerabilities.

This week on With Great Power, Casey tells Brad what National Grid has learned from its work with other utilities and with Rhizome — including a few surprises. They also explore how wildfire preparedness fits into National Grid's broader climate resilience planning, and why the threat looks somewhat different across the utility's UK operations.
