# Transmission of the energy and power values measured so far — NB view Once the intra-year allocation start of the LF for a market location has been reached, the NB transmits to the LF the energy values of the market location measured up to that intra-year allocation start and the two highest monthly maximum demand values of the current calendar year. Note: if the intra-year allocation start is before 2 February, only one monthly maximum demand value is transmitted for January. ## Process flow from the perspective of the NB \nSystem diagram: Übermittlung der bisher gemessenen Arbeits- und Leistungswerte — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\nProcess trigger received\n\nSTART_VERSAND_GEMESSE\nNE_ARB_LEIST…\n\nAPI\n\n1.

## Process information Wording of the consolidated version, profile ch. 3.2.1.1, pp. 82–83.
  1. ### Preconditions - This is a consuming market location. - The LF is the payer of the grid usage. - Values from MSB are available at NB. - The intra-year allocation start (via use case „[Start of supply](/en/prozessdoku/202604/NB/GPKE-Teil2-lieferbeginn)“ or „[Start of the replacement supply / default supply](/en/prozessdoku/202604/NB/GPKE-Teil2-beginn-der-ersatz-grundversorgung)“) has been reached. - The grid usage settlement is based on energy price and demand price. - The information required for the grid usage settlement has been transmitted via the use case „[Billing data grid usage settlement](/en/prozessdoku/202604/NB/GPKE-Teil2-abrechnungsdaten-netznutzungsabrechnung)“.
  2. ### Results A delivery note can be sent.
  3. ### First message The party involved on this page is itself the sender of: „Energy and power values measured to date“ to **LF** (step 1).
  4. ### Objective The LF has the energy values measured at the market location up to its allocation start and the two highest monthly maximum demand values of the market location in the current calendar year.
