[Episode #197] – Virtual Power Plants (VPPs)

May 3 2023

Full Episode

The time may have arrived for Virtual Power Plants (VPPs) to fully realize their potential. In a VPP, groups of distributed energy resources (DERs) like EVs, batteries, and heat pumps can be managed to consume power when it is inexpensive, avoid consuming power when it is expensive, and even provide power back to the grid when supplies are limited.

While VPPs have been around for many years, operating commercially in places like Australia, the US power grid has not seen wide-scale integration. This is now changing because VPPs can help the grid do more with less - supporting new loads without requiring expensive new investments in grid expansion.

In this episode, Jigar Shah, Director of the Loan Programs Office at the US Department of Energy, joins us to share his vision of a much-expanded role for VPPs on the power grid and why he thinks the sector is ready to scale up. You’ll hear how a handful of VPPs and programs to support them have been launched in the US. You’ll also hear how the US Department of Energy is exploring ways to accelerate the development and integration of VPPs, including making financing available through Jigar’s office to support the adoption of VPP-enabled DERs under the Title 17 Clean Energy Financing program.

And because Jigar is with the Department of Energy, sharing information that should be accessible to everyone, we decided to make this one of our occasional lagniappe shows and put it in front of the paywall so that premium and free listeners alike can enjoy it. Hey free listeners, now you can see what you’ve been missing!

[Episode #150] – Resilient and Reliable Power

Jun 23 2021

Mini Episode

As areas like California and Texas struggle amid wildfires, extreme freezes, high winds and other challenges, and take measures to keep the lights on, it’s worth pausing to consider what “resilient” and “reliable” grid power means from the perspective of grid planning. What, specifically, should the operators of the bulk power system do to make their grids more reliable? Do wholesale power markets need to be reformed, to internalize the costs of power shutoffs and send price signals that project developers can respond to? How can new technologies, like demand response systems and microgrids, play new roles in making grids more resilient? And at an even more fundamental level… who is the grid for, anyway? Does the grid exist to serve people, or do people exist to serve the grid?

Energy Transition Show regular Lorenzo Kristov, a grid architect of over 20 years’ experience, has been thinking deeply about these questions and shares his thoughts with us in this episode. Inverting the usual logic of grid planning, he suggests that more active participation by customers and distributed energy resources can help improve both grid resilience and reliability, while democratizing grid power and grid governance. This thoughtful, heady interview will leave even veteran grid experts with more than a few new ideas to consider!

[Episode #94] – Integrated Decentralized Power Systems

May 1 2019

Mini Episode

As more distributed energy resources arrive unbidden onto the power grid, they are increasingly requiring us not to just think about new utility business models, but to radically rethink what a utility might look like. What if millions of distributed resources become the dominant resources, and the grid assumes a subordinate role as a residual supplier of energy? What if the control of the system is also decentralized, through the actions of millions of devices? What if the roles of transmission system operators and the distribution system are diminished as their responsibilities are distributed across all those devices? And how will utilities, power market operators, regulators, legislators, and local officials deal with a radical shift in their roles and responsibilities? These are the questions that our guest in this episode—an 18-year veteran of wholesale power market design at the California ISO—thinks about, and he shares those deep thoughts with us in this wonky yet heady discussion.

[Duke Energy Week extra #2] – Integration and Market Challenges in Grid Evolution

Feb 1 2018

Mini Episode

This is a special, free episode of the Energy Transition Show with Chris Nelder, recorded on November 9, 2017, live from Duke Energy Week at Duke University.

How does utility resource procurement need to adapt to a changing world? Can wholesale markets survive the transition to more distributed resources? Is there a risk of becoming too dependent on natural gas to provide grid balancing services? And how does storage need to be valued in order to fulfill its greatest potential on the grid?

Thanks!

Thanks to Duke University for making this live taping of the Energy Transition Show possible, and to Leah Louis-Prescott, Elihu Dietz, and the rest of the awesome Nicholas School Energy Club for making it all happen and making us feel welcome and appreciated! You're a class act and you put on a great event.

[eLab Extra #6] – Building EV Charging Infrastructure

Jan 18 2017

Full Episode

This is a special, free "extra" episode recorded at RMI’s eLab Annual Summit in December 2016 in Austin, Texas.

Should utilities be allowed to own EV charging infrastructure, or should that be reserved for private charging companies? How many Level 3 high-voltage chargers do we need at workplaces and shopping areas? And how do we build charging infrastructure now that won’t become stranded assets if and when we transition to fleets of autonomous vehicles? We interview Jonathan Levy of Vision Ridge Partners at RMI’s eLab Summit 2016 to find out.

[eLab Extra #5] – EVs and More in Austin, TX

Jan 18 2017

Full Episode

This is a special, free "extra" episode recorded at RMI’s eLab Annual Summit in December 2016 in Austin, Texas.

Through a variety of programs, Austin Energy, the eighth largest publicly-owned electric utility in the U.S., has led the way to an EV future in Texas, installing the first EV charging infrastructure in the region, offering rebates for installing charging stations and the ability to charge up at 250 charging stations throughout the city for a low flat rate using 100% renewable energy. Karl Popham, the Electric Vehicle & Emerging Technologies Manager at Austin Energy, explains how he did it and what other similarly positioned utility leaders can do in an interview from RMI’s eLab Annual Summit 2016.
