Replacement Reserve (RR)

Replacement Reserve is a harmonised service across participating European TSOs for the provision of both an increase and decrease of active power.

  • a minimum capacity of 1MW
  • a response time of less than 30 minutes
  • the ability to sustain delivery for at least 15 minutes
  • registered as either a Primary or Secondary BMU
