ELECTRICITY
CONSUMPTION
• High power consumption
- ICT 10% UK electricity
- Data centres 1.5% (8GW)
- 46 TWH 2006 to 93 2020
= aviation/refrigeration
• High summer load
- system reliability

WHY IT MATTERS TO HE
• Cost
- 50 to 100% rise in electricity prices?
• Carbon
- growing regulation
- Carbon Reduction Commitment
• Capacity
