PUDL v2024.10.0 is out today, and it includes a never before openly available dataset: county-level hourly renewable generation profiles from @drchrisclack

You can explore the dataset through this Jupyter notebook, which we used to generate the attached animations.

Thanks to GridLab for supporting the data integration work.

Way back in 2017, @drchrisclack appeared on @TransitionShow
to talk through some of the flaws that he and colleagues had found in the 100% wind, water and solar model proposed by Stanford’s Mark Jacobson in 2015, and what more realistic modeling of a 100% renewable system might look like: https://xenetwork.org/ets/episodes/episode-46-100percent-renewables/

Jacobson sued. Nearly 7 years of legal wrangling passed. And today, it's over. Clack won. https://twitter.com/DrChrisClack/status/1769817536931955154

[Episode #46] - Is 100% Renewables Realistic? | The Energy Transition Show

Can we run the world on 100% renewables? Is that even the right goal? A new critique of Mark Jacobson’s model on 100% wind, water & solar offers insights.

@smokeygeo @chrisnelder @drifthood @TransitionShow @supernovae we have also modeled this a LOT with many different costs for solar, storage and other technologies and it all still holds true!

@smokeygeo @chrisnelder @drifthood @TransitionShow @supernovae Final response. The cost of storage is 2 components. BOTH power & energy. Costs have actually come down a lot. But more in cells than inverters. these plots are for utility-scale. DistrD is more expensive! Moreover, the arguments you have all don’t hold because even if costs are lower than you “believe” the distr ones R much more expensive for both solar & storage. Yet saves system costs!

@smokeygeo @chrisnelder @drifthood @TransitionShow @supernovae You are making a straw man. This will be my last response. These costs are 1. DC, 2. Don’t inc interconnection, 3. Don’t inc our regional multipliers, 4. Don’t inc ITC (or PTC), 5. We see a closing in cost over time, 5. We did not split different distributed in the images (C&I vs R). I have stated all this before, but you ignore. Most important, w/ higher cost still saves system money!

@smokeygeo @drifthood @TransitionShow @supernovae I suspect you are still missing the original point that I was making. You are still looking at what a developer's costs might be. The point is that the full system costs--a superset of the developer costs--can make local solar cheaper (i.e., to society) because of co-optimization, as @drchrisclack's model shows.

@smokeygeo @chrisnelder @drifthood @TransitionShow @supernovae solar and storage in the distribution grid lowers the cost for all customers. It allows more utility scale and reduces over building as well. In addition it adds resiliency.

@smokeygeo @chrisnelder @drifthood @TransitionShow @supernovae because what you are quoting is not true. That’s the issue. Solar and storage in the model are NEVER less than utility scale. So, I don’t understand your points.

@smokeygeo @chrisnelder @drifthood @TransitionShow @supernovae since we also have regional cost multipliers for each state as well, which pushes costs higher even more.

@smokeygeo @chrisnelder @drifthood @TransitionShow @supernovae yes, and match ours very nicely. Since our costs are in $/kWdc. Before interconnection to the grid.
