Based on a 50 MW IT load and the difference in cooling efficiency between mild and hot weather:
* On each hot summer day (e.g., July or August), the air-cooled system would use an additional ~360 MWh/day compared to spring/fall conditions.
* Over 60 summer days, that adds up to an extra 21,600 MWh of electricity consumed just to handle less efficient cooling.

==== - Peak grid demand rises significantly in summer—not just from compute, but from cooling inefficiency. ====
* That additional 21.6 GWh could: - Power over 2,000 homes for a year - Represent a ~15–20% spike in electricity use for the data center in summer
* It also increases pressure on local generation, especially if wind output is low and solar is limited to daylight hours.

Let me know if you'd like to model this for a larger load (e.g., 100 or 200 MW) or estimate the size of a solar + battery system that could offset that summer delta.
