Because uncommon, delivering a project within ±20% budget & schedule is the main obstacle the nuclear industry faces to spur new constructions
However, furthering the analysis wrt past vs recent, causes/drivers and reactor designs results in different conclusions

1) underplay VRE's short-run marginal cost dispatch thresholds
2) misunderstand integration with other resources (not just addition onto the system)
3) understate trade-offs wrt enabling infra (grid AND molecules)

Since April 28th, some commentators have scrambled to present dubious explanations (inertia, ties with 🇫🇷, etc); after last week's gov & TSO reports, specific conclusions can be drawn and unknown aspects highlighted

For more clarifications, we'll need to wait for the upcoming ENTSO-E investigation's report, but a clearer picture is starting to take form as more data & information become available

- the first (and bigger) atypical voltage oscillation linked to anomaly in PV farm behaviour
- effect worsened by % of networks not responding in accordance with power factor & load-shedding measures (further discharging lines and > reactive input)
Final report with comprehensive analysis and recommendations in the upcoming months #EnergySky 🔌💡

Also arguing against nuclear on time value of money grounds ignores more patient public capital.

Likely inaccurate! NRC documents + grid data show River Bend made a routine shutdown days earlier to check a backup feedwater system leak.

Investigators seem to have ruled out an imbalance in supply & demand or insufficient grid capacity

- oscillations preceded the incident
- regarding first loss of gen, no trips observed in Portugal and France
- Portuguese plants with black start capability had unsuccessful attempts

Inertia doesn’t scale with generation output but rather with spinning generator mass. Spain had 4 reactors online, 2 at 70% power, providing inertia equivalent to 4 reactors at full power! More thoughts below.🧵
Why? Here's a hefty piece digging into that, for you:

marking the fourth year in a row with at least 10 new approvals.
The new reactors are expected to cost 200 billion yuan and will be deployed at 5 sites

1) Fossil fuels made possible unprecedented human prosperity during the last 150 years.
2) Their byproducts are harmful.
We've reached a level where we can replace fossil fuels and still ensure human well-being, but some prefer to keep polluting.

My research students at @wellesley.edu and I are tracking it.
Here is what has progressed and what has slowed in wind, solar, EV, and battery sectors after Trump 2.0 + 1 month.

The upcoming Abu Dhabi project has sparked much interest, from the claim of baseload power to the relatively low costs to achieve it: what does this mean for system planning, capacity expansion, and grid augmentations? Let’s dive in!

The new Belgian government is working to reverse their nuclear phaseout, but the turnaround didnt happen in time to save this plant (yet).
The plant is owned by a French gas company.

- negative learning❌ stop-start approach✅
- unwarranted skepticism about cost & schedule reductions from a fleet strategy (not if, how much)
- consortiums to finance and reduce risk exposure remain key
