Self-hosted AI rack costs ~$100/mo in power, plus a Bay Area 30¢/kWh problem
mertdumenci · x · 2026-10-22
Two developers compared notes on the power economics of self-hosted AI hardware:
- One pays 13¢/kWh with a rack idling at 1kW — about $100/month, still cheaper than colocation
- The other, in the Bay Area at >30¢/kWh with no real export credit for solar, is weighing a battery or building a tight-loop job scheduler that shifts workloads to when excess solar power is available
