Power response

Power response sites provide flexible support to the grid at times of peak demand. They are essential to support the intermittency of increased renewable energy generation.

The Government’s energy security strategy predicts that electricity demand is likely to double by 2050. The shape of that demand is expected to change significantly, due to factors such as:

  • Smart homes – where households use electricity in different ways, and at different times
  • Changing grid patterns
  • Electric vehicle charging patterns
  • The electrification of heat and transport.

This changing environment means that having backup electricity capacity is more important than ever before.

At peak times, short-term support may be needed, to help meet demand. That’s where power response sites come in.

Power response explained

Power response sites are small, local power stations which are kept on standby.

When electricity demand is high, or generation low, we can switch our power response engines on and supply urgent backup to the grid. This flexible power is provided for as long as it’s needed.


Capacity market and STOR contracts

Power response services provide critical grid backup. All Infinis sites have contracts in place with the National Grid, that commit to provide electricity when required. This gives the National Grid assurances that they can turn on power if demand increases.
