AI Grid Impact Forecast Tool
Project how AI and data centre growth could increase electricity demand in a UK region, and what that means for infrastructure and grid stress.
Important: These tools provide educational estimates only. Actual AI electricity use varies by model, data centre, cooling system, hardware, location and workload. Do not use these results as official energy, planning, investment or engineering advice.
Scenario
Infrastructure requirements
In London & South East, this scenario adds roughly 8.5 TWh per year (about 9% of current regional demand). Grid stress is rated Moderate — Targeted reinforcement likely needed. Expect pressure on substations, transmission upgrades and connection queues.
How This Calculator Works
We take an approximate baseline annual demand for the region, then apply a growth-scenario factor and an AI-adoption multiplier to estimate additional demand. The stress rating compares additional demand to the regional baseline.
What The Result Means
A higher percentage and stress rating signal a greater likelihood that the local network needs reinforcement, new connections or generation to keep pace with AI-driven growth.
Limitations
Regional baselines and multipliers are illustrative. Real planning uses detailed network and FES data.
