ESB Networks Pilot of Scale
ESB Networks Pilot of Scale

ESB Networks Pilot of Scale, in Mullingar and surrounding areas, is about piloting flexibility services with customers as a Distribution System Operator. ESB Networks will procure flexibility services from contracted Flexibility Service Providers (FSPs) operating on specified MV feeders fed from the Mullingar Bulk Supply Point.

Competition - Piclo terminology for a specific flexibility requirement relating to a tender.

Compliance - The use of flexibility is mandated over other alternatives.

Connection Level - The voltage level of the network the asset needs to be connected to

Contract start and end date - The start and end dates of contracted flexibility service that will be awarded via the tender process on e-tenders platform.

Estimated utilisation duration per event - An estimate provided by the DSO on how long the dispatch with lawst.

Estimated utilisation events - An estimate provided by the DSO on how many times they think flexibility will be dispatched between the contract start and end dates.

Estimated utilisation hours - The estimated utilisation event x the estimated utilisation duration

Flex Provider - A company that owns and/or operates assets that can provide flexibility.

Minimum aggregate size - The minimum capacity a FSP must have have in a specific location in order to provide flexibility services

Minimum run time - The minimum time an asset or aggregate group of assets must be able to dispatch its contracted capacity.

Need Direction - The direction that energy from the flexible asset needs to flow to maintain the network. 

  • Generation turn up / Consumption turn down means the network needs more energy so assets supplying flexibility either need to export more energy in or reduce the amount of energy they are consuming. 
  • Generation turn down / Consumption turn up means the network has excess energy so assets supplying flexibility either need to reduce the energy they are exporting or increase the amount of energy they are consuming. 

Need Type - The reason the DSO needs the flexibility. The need types are Pre-fault, Post-fault, Compliance, and Reinforcement Deferral and Other. 

Pre-fault - Flexibility can be used to avoid a fault on the network, reducing the likelihood of an outage.

Post-fault - If an outage has occurred, flexibility can be used to help restore the network

Power Type - The type of power the flexible asset needs to supply in order to meet the flexibility requirement. The DSO may require either active or reactive power.

Product Type - These have been adopted from the UK’s ENA standardisation work. The product types are Sustain, Secure, Dynamic and Restore. Read further details on these flexibility products here via Energy Networks

Qualifying assets - Assets cannot qualify on Piclo and must go through the PQQ process on the e-tenders platform.

Qualification close - The date that all documentation must be submitted for the tender process run on the e-tenders platform.

Reinforcement deferral - Flexibility is used to increase the capacity of the network rather than building more infrastructure. 

Total need - The total flexible capacity in MW or MVar that the DSO requires for a certain area as specified in the tender

All questions and contact must be through the e-tenders platform.
