April 2020 Standalone Release

The Release implementation date is 1 April 2020.

Scope of the Release

The Release includes two industry-led changes. 

These are:

  • P354 (“Use of ABSVD for non-BM Balancing Services at the metered (MPAN) level”) 
  • P388 (“Aligning the P344 and P354 Solutions”), due for approval on 8 August 2019.
    • We do not anticipate this Modification will directly impact Parties over and above impacts already identified through Modification P354, other than some system calculation steps. This Modification aligns P354 with P344 that will be implemented in December 2019.

The document impact matrix is available here.

Further details will be added as they are available, to this page.
