What is Flexibility?

‘Flexibility’ is the capability of energy resources, such as generators, batteries and consumers, to change their behaviour.

This behaviour change can help to reduce the pressure on the grid at certain times, such as during the evening (traditionally when demand for electricity is highest) or when very windy or sunny (when generation is highest). A good example would be charging an electric vehicle overnight rather than during evening peak.

It means participating homes and businesses can earn payments, while saving costs for everyone and helping more low-carbon technologies to connect to the network. 

Our latest tender  

Our Spring 2025 tender set aside several million pounds to procure 122MW across 260 zones while our Autumn 2025 tender looked to cover 335 zones. Flexibility tenders are opportunities for providers who can:  

• Reduce consumption or increase generation at times of peak demand
• Increase consumption or reduce generation at times of excess renewable generation 

If you’d like to participate, please refer to our Participation Guidance (PDF) or view our latest Flexibility webinar.
