FYI - EIA has analysis on the energy increase - https://www.eia.gov/todayinenergy/detail.php?id=65284

Relative to data center growth, the correlation doesn't match - https://ourworldindata.org/grapher/monthly-spending-data-cen...

More analysis here - https://www.wri.org/insights/whats-driving-us-electricity-pr...

But TL;DR - sounds like in the northeast / PJM it's load increases, in North Dakota increased load is causing drops in prices, California it's mostly from wildfire mitigation + insurance, natural gas oscillating across the US is causing price changes as well.

Thank you, your comment was more informative than the economist article
