  • Contain the numbers of packages per the specific hours of the 24-hour period the bid relates to
  • One package is made up of 1 MWh
  • Have the same price for all hours covered by the bid
  • Are accepted by GAZ-SYSTEM based on the following criteria:
    • type of service, depending on the system’s needs,price,
