Great Britain's national electricity demand recorded by the National Energy System Operator, reported at half-hourly resolution across each day. Each row is a settlement period with the corresponding national demand in megawatts, alongside related measures such as transmission system demand and embedded wind and solar generation. The dataset captures the minute-to-minute rhythm of national power use, including the sharp, predictable demand spikes known as TV pickups or the kettle surge, when millions of viewers switch on appliances at the same moment during televised events like World Cup matches. Used here to show the real halftime and full-time demand surge in actual grid data. Source: National Energy System Operator (NESO) Historic Demand Data.
This dataset appears to contain energy demand and supply data for England and Wales, including forecasted and actual values for various sources such as wind generation and solar power. The settlement date indicates when each day's value is recorded.
The quality scores indicate that the dataset has high completeness (100%), uniqueness (100%), and validity (93.82%) but slightly lower consistency (80.93%).
1. Analyzing energy demand patterns over time to inform grid management decisions
2. Evaluating the impact of renewable energy sources on energy supply
1. Data may not reflect real-time changes in energy demand due to the settlement date
2. Forecasted values may not accurately predict future energy demands.
