Show Notes
In this episode, Rachel Permut draws on decades of experience in distributed energy and virtual power plants to explain how demand-side flexibility is becoming a critical grid resource. She breaks down what DERs and VPPs are, why customer enrollment and revenue mechanics matter more than the “shiny” technology, and how fragmented U.S. markets create both complexity and opportunity, with DR payments now reaching up to $100/kW in some regions. Rachel dives into the evolving role of data centers, including flexible AI and batch workloads, water-based cooling trade-offs, and emerging models where data centers pay others on their circuit to reduce load. She outlines the full demand response lifecycle from contract and enrollment through dispatch, baseline measurement, and payment, highlighting where programs typically fail and how better communication, software, and market design can unlock more value. Ultimately, she argues that DERs and VPPs are not a silver bullet but are fast, cost-effective tools that must play a much larger role alongside new generation to address growing grid stress.
