Energy System Logic
The energy architecture operates on a priority dispatch model. Nuclear generation provides the always-on baseline, typically covering 70-80% of total demand. Renewable sources (primarily wind at northern latitudes) supplement nuclear output during favorable conditions, reducing marginal energy costs.
Battery energy storage systems (BESS) provide rapid-response capacity for demand spikes and bridge short-duration gaps between generation sources. Thermal energy storage captures waste heat from both nuclear generation and compute operations for district heating applications.
- Nuclear Baseline: 70-80%
- Renewable Supplement: 15-25%
- Storage Buffer: 5-10%
