#Net-Zero Opt-Tech High-DC

With higher data center load, electricity use in the buildings sector increases, with a proportional scale-up in the supply of low-carbon electric generation (Figure 22). Under a net-zero target with optimistic technology assumptions the long-run marginal generation mix to meet incremental data center load varies by region, but at the national level is comprised of a combination of variable renewables and low-carbon baseload power from gas-CCS and nuclear, as well as firm balancing capacity in the form of conventional gas (with fuel flexibility) and storage.
