As reported in the Independent, electricity prices went negative in Germany for the first time on 8th May.
Why?
- They generate a lot of both wind and solar power
- Demand for electricity has not been managed to match intermittent renewable supply
- They would rather keep renewables running than switch them off, even if it is more expensive to do so.
What are the lessons for UK?
- Manage demand to more closely match the cost of intermittent supply
- Raise awareness of this issue with domestic consumers who have the power to manage their demand patterns far more than they currently do
The prize for doing this is huge - of the order of £50 billion if the alternative is Hinkley C type power stations.
