Flexibility Roadmap
Flexibility is the future for electricity networks. The UK Power Networks Flexibility Roadmap looks at radical proposals to drive the market for flexibility services and helping to reduce our customer’s bills. 

We’re proposing to adopt a ‘flexibility first’ approach to delivering additional network capacity, which we believe will lead to lower costs and increased renewable energy on the network through more competition. We want to know what you think about our proposals and our consultation is open until 8 October 2018. Read our Flexibility Roadmap.

Flexibility Service Design consultation

These are exciting times for our industry. The nation’s journey to a low carbon economy is revolutionising the way we produce, distribute and consume electricity.

Whilst we continue to operate and invest in the network to maintain a safe, secure, and sustainable power supply to 8 million homes and businesses, we need to make use of smart, flexible, and innovative techniques to ensure delivery of our outputs, minimise the cost impact on consumers, and manage the increased complexity of this low carbon world.

At UK Power Networks, we believe that customer flexibility will be central to facilitating a smarter, flexible energy system.

Our flexibility programme is looking to utilise response from generators, demand side providers, and electricity storage resources connected to our networks to support efficient network planning and operations.

We are consulting to gather stakeholder views on a number of areas to shape the nature of the flexibility contracts we put in place, in particular:

  • The design of the payment structures, including the use of availability windows;
  • The compatibility with other system services, and the means of avoiding conflicts;
  • The use of performance incentives, including the use of baselining;
  • The treatment of new service providers, and in particular the interaction with the connections process;
  • The timeline of procurement proposed for each tender round, and
  • The approach to assessing received tenders.

At a time of unprecedented change in our industry and in society generally, it is more important than ever that we listen, collaborate and share. Engagement is central to UK Power Networks’ business strategy.

Please send all responses back using the response form to by 4 August 2017 - the consultation is now closed.
