Critical Evaluation
Value of the Information & Strength of the Argument
The presentation provides valuable insights into the behavioral response to power outages and the estimation of a crucial economic parameter. The argumentation is solid, based on a clear identification strategy and robust data. The use of a dynamic discrete choice model is appropriate for capturing the durable good decision under uncertainty. The authors acknowledge limitations and potential biases, such as the conservative nature of their VOLL estimate. The findings have significant policy implications for electricity market design and environmental justice.
Scientific Rigor, Source Quality, Title Accuracy
The study appears methodologically rigorous, using detailed feeder-level outage data and a difference-in-differences design with event study analysis. The speaker cites relevant literature and acknowledges the ongoing debate on two-way fixed effects models. The title accurately reflects the content. The presentation is based on original research, and the speaker is a credible academic. No external sources are cited beyond the speaker’s own work and general references.

- Data description: zip-code-level battery adoption, feeder-level outage data, and geospatial mapping.
- Methodology: difference-in-differences and event study design.
- Results: significant increase in battery adoption in treated zip codes, with heterogeneity by income.
- Dynamic discrete choice model to estimate value of lost load (VOLL).
- VOLL estimates: $3,600 to $7,000 per MWh, compared to literature.

Contribution & Novelties
This study provides a novel revealed-preference estimate of the value of lost load (VOLL) for residential customers, using observed battery adoption decisions in response to power outages. It is among the first to use averting expenditures in the electricity context and contributes to the environmental justice literature by documenting income-based disparities in adaptation. The findings have implications for electricity market design and reliability standards.
