Final guaranteed supply or FGS – the temporary delivery of natural gas to the owner of a gasified object if natural gas is used at the gasified object without a written natural gas sales contract. FGS for households is provided by Latvijas Gāze. The technical supply of natural gas is provided by Gaso AS.
You are obliged* to conclude a natural gas sales contract within 6 months from the date of the notice, otherwise the natural gas supply to the gasified object may be interrupted.
Conclude a contractIf you conclude the contract by the 15th of the current month, the contract will take effect from the 1st of the next month. However, if you conclude the contract starting from the 16th of the current month, the contract will enter into force on the 1st of the following month.
* Paragraphs 64.2, 70.1, 100.6. of Cabinet Regulation No. 78 “Regulations Regarding the Trade and Use of Natural Gas” stipulate the obligation to conclude a natural gas sales contract within six months and the responsibility of the owner of the gasified object if no natural gas trade contract has been entered into.
FGS price
From 1 July 2023, the methodology for calculating the price of the FGS service changes. From now on, the price will vary on a monthly basis and will consist of a variable and a fixed part according to a formula:
FGSVAR = TTFfm (arithmetic average daily settlement price of the Title Transfer Facility financial instrument for the following month, EUR/kWh + Markup, EUR/kWh
+ FGSFIX (fixed monthly FGS service fee, EUR/per gasified unit per month)

How does an FGS service differ from a service provided under a concluded contract?
The Energy Law stipulates it compulsory to conclude a written natural gas trade contract. Having a written contract will protect you from the unexpected cut-offs or increased charges for the natural gas supply. The contract is a mutual promise and provides a much greater sense of security.
The legislator has stipulated that in cases where no contract has been concluded, the responsibility for the settlements, consumed natural gas, and distribution system services, as well as compliance with the security regulations shall be assumed by the owner of the real estate. In many cases, the owner does not use the property himself or herself, but, e.g., rents it to tenants or allows relatives to use it. There are often situations where the owner is confused regarding the transfer of the debt accumulated in the property and transfer of the owner's data to the debt collection companies.
We ask you to not postpone the conclusion of the agreement as the distribution system operator GASO has the right to suspend the supply of natural gas if the person using natural gas at the relevant address has not concluded a natural gas trade contract.
