Capacity conversion

This service is based on the ENTSOG capacity conversion model according to article 21 (3) NC CAM.

• CAPACITY: The capacity (kWh) on the existing unbundled booking must be at least as large as the bundled capacity to be purchased in the auction.  
• RUNTIME: The end date of the existing unbundled contract must not be before the end date of the bundled capacity offered in the auction.
• NUMBER OF CONVERSIONS: Only one conversion request per auction can be submitted via PRISMA per shipper, regardless of whether the capacity conversion originates from a single unbundled booking or from multiple bookings.

If your situation does not meet these criteria, please contact our Customer Desk at least 10 working days before the start of the relevant auction to discuss the possibilities of a manual capacity conversion.  

If your situation does meet the above conditions, the following applies: 

During an auction for bundled capacity on the PRISMA platform you can indicate that you want to convert unbundled capacity to bundled capacity. An instruction ('Convert capacity at PRISMA auctions') can be found at the bottom of this webpage. 

The unbundled and bundled capacity should of course be on the same (V)IP and in the same flow direction. The product type of the converted unbundled capacity remains applicable to the new bundled capacity. If on PRISMA an auction premium ('surcharge') has been paid for the new bundled capacity, this premium remains applicable on the total bundled capacity. 

Capacity conversion through PRISMA is possible during auctions of annual, quarterly, monthly and DA capacities. If manual actions are required, capacity conversion is not possible in DA auctions. Capacity conversion is not possible at all during auctions of within-day capacity. 

After the end of a PRISMA auction, your existing unbundled contract will be reduced by the amount of the bundled capacity purchased at the auction. The capacity that becomes available again as a result of the conversion will be offered in the next auction of capacity for the same period. For example, capacity converted during the monthly auction will be offered again in the DA auction in the same month.

After the conversion has been successfully processed by GTS, you will receive a confirmation by email. If you converted capacity during the DA auction, this email will be sent around 17:45 LET.  If the conversion could not be performed, you will receive an email about this within a few minutes after the auction closes.
