Data Centers and the Rules We Have Not Written Yet: Should we ban data centers? Science cannot answer that, but it can sharpen the trade-offs. New Amped Up post on prices, emissions, air quality, and four questions policymakers should be asking. #energysky open.substack.com/pub/paulinaj...

Beneficiary-pays cost allocation has been a rare point of analytical convergence in transmission policy. EPRA (2024) gestured toward it. FERC’s Order 1920 operationalized it. The FAIR Act would unwind it. #EnergyPolicy #Transmission #FERC open.substack.com/pub/paulinaj...

Program managers indeed make the final award decisions based on recommendations from the review panels. However, program managers are typically career scientists and not political appointees.

Peer review is mentioned. The EO says explicitly that agency leads are not required to follow the recommendations from review panels when making award decisions. The order gives final granting authority to political appointees. Here is a helpful summary: arstechnica.com/science/2025...
