big late breaking news: the market monitor for the largest energy grid in the u.s., covering much of the midwest and mid-atlantic, has called to block new data centers connections to the grid, saying current course of growth assures regular blackouts
No more PJM data centers unless they can be reliably served: market monitor
The PJM Interconnection’s market monitor urged the Federal Energy Regulatory Commission to rule that large data centers can only come online if the grid operator can still meet reliability metrics.

Still no word of any progress on the negotiation front. What’ll happen if there’s no agreement by Tuesday?
Trump’s Colorado River deadline is almost here. Is Utah ready for cuts?
Because of drought, mandatory water cuts are nothing new in Utah. But the potential of large-scale reductions across the Colorado River Basin would present a steep challenge.
