'We're buzzing': Octopus Energy is giving away more free electricity to its 8 million customers — and it could stop the UK wasting £1.5 billion to shut down wind farms

• Britain spent nearly £1.5 billion shutting down renewable electricity generation last year
• Smart meter households can now receive free electricity during surplus renewable generation periods
• Octopus customers have already saved millions through experimental free electricity flexibility sessions

The UK is generating more renewable electricity than ever, but its grid often cannot use it all - as when the wind blows hard, or the sun shines bright, and demand is low, demand can fall below what is being produced.
