Is now the time for DERs to scale?
8 snips Sep 18, 2025
In this engaging discussion, Andy Lubershane, a partner and head of research at Energy Impact Partners, dives into the evolving landscape of distributed energy resources (DERs). He explains why they failed to thrive a decade ago, primarily due to high costs and low market demand. Now, with increasing grid bottlenecks and decreasing costs, he makes a compelling case for a DER comeback. The conversation also unpacks the differences between demand response and virtual power plants, and the potential challenges that still lie ahead for scaling these innovative technologies.

Episode notes
Dispatchability Is The Key Differentiator
- Many DERs like solar and energy efficiency help planners but lack an "on/off" button for real-time grid operators.
- Grid operators increasingly need dispatchable resources that can be controlled in real time.
DERs Have Useful Limits
- Batteries and flexible loads provide dispatchable capacity but have limits like duration or customer tolerance.
- Operators must plan around those limitations rather than treating DERs as full replacements for traditional assets.
2017 Utility Engineers Found Few NWA Wins
- In 2017 EIP convened utility engineers to ask where non-wires alternatives were being used and found almost none.
- That experience convinced Andy the system simply didn't need DERs widely back then.
