UK Grid Sim Can you match supply and demand on the UK grid? Real demand and generation data June 2024 to June 2025
Power view (GW):
Summary
| Demand | {{ demand_GWh*0.001 | toFixed(1)}} TWh |
| Supply | {{ supply_GWh*0.001 | toFixed(1)}} TWh |
| Oversupply factor | {{ supply_GWh/demand_GWh | toFixed(2) }} |
| Curtailment | {{ balance.surplus*0.001 | toFixed(1)}} TWh ({{ 100*balance.surplus/supply_GWh | toFixed(0) }}%) |
| Unmet demand | {{ balance.unmet*0.001 | toFixed(1)}} TWh |
| Demand supplied directly before storage | {{ balance.before_store1*100 | toFixed(0)}} % |
| Balance after battery storage | {{ balance.after_store1*100 | toFixed(0)}} % |
| Balance after LDES | {{ balance.after_store2*100 | toFixed(3)}} % |
