Prices for gas storage facilities

Customers using gas storage facilities in the Czech Republic book:

  • Transmission capacity with NET4GAS for the transmission of gas to and from gas storage facilities using the tryGAS system, and
  • Storage capacity, injectability, and deliverability with the storage system operator for gas delivered to and from the storage facility. Bookings are made in auctions organized by the applicable storage system operator.

The transmission capacity price consists of firm and variable components.

    • CZK 442.96 per MWh per day for entry points to the transmission system (delivery from storage facilities), and
    • CZK 95.6 per MWh per day for exit points from the transmission system (injection into storage facilities).

The firm price for monthly firm transmission capacity CZM in CZK per MWh per day is calculated using the following formula:

CZM = Cz x Fz

Legend:

 

FZ

Booking duration factor for a transmission capacity booking, where the following applies:

FZ = Mz/12 for a booking of 12 months and longer
FZ = 0.098 x Mz0.95 for a booking of 11 months and less

 

Mz

Number of months for which firm monthly transmission capacity is booked

 

The firm price for daily firm transmission capacity CZD in CZK per MWh per day is calculated using the following formula:

CZD = Cz x FD

Legend:

 

FD

Factor of the number of gas days of the duration of a transmission capacity booking, where the following applies:

FD = 0.005 x d0.88

"d" is the number of days for which firm daily transmission capacity is booked for day-ahead firm transmission capacity; "d" is equal to 1.

 

The firm price for within-day firm transmission capacity CZV in CZK per MWh per day is calculated using the following formula:

CZV = Cz x 0.01
