Access to the new balancing system
(1 of 2)
The “Enabled User” is the User of storage and transportation services that
owns flexibility resources for balancing purposes and shall be required to
contribute, using its own resources, to the balancing of the system; the
access requirements are as follows:
Holder of a valid and effective transport contract;
Holder of a storage contract for the modulation service, the hydrocarbon
service or Legislative Decree 130/10 service (not required for
balancing users);
To be authorised for access to the Virtual Trading Point;
Holder of ratings and/or guarantees in compliance with the provisions of
the Network Code.
4
Access to the new balancing system
(2 of 2)
SRG checks the requirements for access to the balancing system in order to
prepare the list of Users which shall contribute (holders of storage
contracts) and the list of the balancing Users (all network Users); to this
end:
 It determines the System's potential exposure of each user (EPSu);
 It determines the maximum potential exposure in relation to the
guarantees given by the User (MEPSu);
 It manages the system of guarantees to cover the System's exposure
of the User;
 It compares the EPSu and MEPSu of each User;
 It takes the necessary measures if the System is overexposed to the
User.
5
Calculation of the system's potential exposure to the User (EPSu)
(1 of 5)
 The EPSu or potential exposure of the System to the User is the potential debt, calculated
on a daily basis, of the User with reference to the balancing service.
 The EPSu is the sum of the following components:
 Pfatt: due amounts billed and still not paid by the User;
 Pdet: provisional due amounts calculated and still not billed to the User;
 Patt: potential due amounts that may arise for the User in the three months following
the valuation.
Bills receivable (GME - Electricity Market Operator - items)
Bills receivable (Imbalances)
PFATT
Credit notes receivable (Imbalances)
Bills payable (GME items and/or imbalances)

Point - Transactions)
6
Calculation of the system's potential exposure to the User (EPSu)
(2 of 5)
 Pfatt is composed of bills and credit notes, receivable and payable, relating to
the economic items calculated on the PB-Gas platform and to imbalances of
Users of the balancing service.
 These economic items are a result of the calculation of the EPSu once they
have been paid or reached maturity.
 Pdet is the sum of economic items still not billed, determined on the basis of
the most up-to-date transport balance; they are a sum of the following
components:
Economic amounts receivable and payable relating to transactions
completed on the PB-Gas platform by the User authorised by SRG and
valued at the remuneration price;
Economic amounts receivable and payable relating to imbalances of
the balancing User and valued at the imbalance price.
7
Calculation of the system's potential exposure to the User (EPSu)
(3 of 5)
Patt is the potential due amount calculated as sum of the following components:
Transactions recorded at the Virtual Trading Point;
The cumulated imbalance the User may reach in the three months
following the valuation, calculated using an expected withdrawal estimate.
The aforementioned terms are assessed in the assumption of input by the User equal to
zero and are valued at the estimated imbalance price.
In order to estimate the expected withdrawal of the User, the calculation criteria will take
into consideration the capacities assigned to both the entry and redelivery points
appropriately re-proportioned on the basis of the average load factors of such capacities.

 Users of the Capacity Portal will have the opportunity to check the components of their
EPSu in real time in more detail.

10
Calculation of the maximum potential exposure of the system to the User (MEPSu)
(1 of 6)
 The MEPSu or maximum potential exposure of the System to the User corresponds to the
maximum acceptable EPSu value, calculated on the basis of the following components:
 Gmin is the guarantee the User is required to present in order to access the balancing
service;
 G are the guarantees actually presented in the form of security deposits, bank
guarantees, rating certifications and guarantees in gas held in storage;
 C are the expired invoices and not paid yet relating to the balancing service.

Calculation of the maximum potential exposure of the system to the User
(MEPSu) (2 of 6)
The following types of guarantee may be presented:
 Security deposit: the associated amount may be used to fully cover the
guarantee the User is required to present;
 Bank guarantee: the associated amount may be used to fully cover the
guarantee the User is required to present;
 Parent Company letter of guarantee: the associated amount may be
used to fully cover the guarantee the User is required to present;
 Credit rating: possession of a minimum credit rating required by the
Network Code covers X% of the value of the guarantee the User is
required to present;
 Gas in stock at one or more Storage Companies.
12
Calculation of the maximum potential exposure of the system to the User
(MEPSu) (3 of 6)
 The adjustment of the amount of the guarantee given must be

Warning and Blocking Messages
16
Balancing Operator Actions in the event of the system's overexposure to the
User
(1 of 2)
 In order to limit the risks related to the potential exposure of the
System to the Users, on each gas day the conditions which
compare the EPSu and the MEPSu must be observed;
 SRG, as Balancing Operator, calculates and communicates to GME
on a daily basis the economic limit of the purchase offers that the
User can formulate on the PB-Gas platform.
17
Balancing Operator Actions in the event of the system's overexposure to the
User
(2 of 2)
 The Balancing Operator monitors the relative operational
economic margins for each balancing user on a daily basis.
 Based on the level of potential exposure EPSu with respect to the
maximum potential exposure MEPSu:
 The Capacity Portal displays to the User a warning/blocking
message;
 SRG sends a written notification to the User (and also to GME
and Storage Companies);
SRG blocks, with immediate effect, the operations of the User
in relation to capacity bookings and selling transactions on the
Virtual Trading Point.

Transportation programs and Balancing
Introduction
 In order to ensure the daily balancing of the system, Enabled Users are
required to make their storage resources available to the Balancing Operator.
 The process defining the transportation programs in the new system will be
characterised by:
 Publication of Estimates on gas day G to provide an overview of the system status;
 Renomination on gas day G to allow User to rebalance its input and withdrawal
quantities;
 Bids on gas day G aimed at making the storage resources available to the system.
 During the Allocation and Balance phase, Enabled Users will be supplied with
the outcomes of their balancing actions implemented during the transportation
programs phase. The balancing process in the new system will be characterised
by:
 Bids Accepted, provided on gas day G+1, that has been selected to balance the
system;
 Position in Storage which is determined as final on gas day G+1;
 Value of Imbalances (whose coverage is no longer ensured through its storage
resources), provided as definitive in gas month M+1 and M+3 .

Introduction
 The quantities of gas exchanged on the Balancing Platform to cover the
Network Imbalance and the Imbalances of individual Users are subject to
Billing.
Snam Rete Gas, as Balancing Operator (RdB):
 procures balancing resources on the market and manages the settlement of bids
selected on the Balancing Platform;
 performs the settlement of gas items that are considered to have been exchanged
with the Balancing User for the coverage of his imbalance.
 The Balancing User must issue bills payable by the Balancing Operator in the
following cases:
 Sale of quantities of Gas on the Balancing Platform;
 Positive imbalance.

The Bills Receivable issued by the Balancing Operator to the User will contain two separate items,
relating to the aforementioned economic amounts: economic amounts relating to transactions on the
Balancing Platform and economic amounts for the coverage of the imbalance.
The price at which the transactions on the Balancing Platform are valued is the remuneration price
equal to the price of the last accepted offer.
The imbalance price at which the quantities of gas are valued relating to the imbalance always coincides
with the remuneration price, except where the overall system imbalance is less than 6000 GJ. In this
case, the imbalance price will be the average price of the last 30 days with the exception of emergency
days due to gas excess and deficiency.
53
Gas Month M+1
Billing- Transactions at zero
 The remuneration price calculated on the Balancing Platform is equal to € 0
(zero) in the event in which the quantities subject to the selected bids of
enabled users are less than the quantity of gas (overall system imbalance) bid
for sale by the Balancing Operator.
 As regards said gas movements, against a tax base of zero, VAT should, in any
case, be calculated in the bill (10%).
 SRG will issue a specific bill to manage this particular case.
 The price to value said transactions (for the purposes of calculation of VAT) is
equal to the latest available value of the wholesale marketing price (CCI).
54

Billing Receivable – Billing Portal
 Balancing Users will be able to view in detail the amounts of receivable bills that
Snam Rete Gas, as Balancing Operator, has issued them.
 In the Billing Portal, receivable bills can be selected through a dedicated and easily
identifiable item.
 More specifically, in the Billing Portal, two compressed files can be viewed (one
for bills at a price higher than zero and the other for any bills at zero price, each
containing the bill and the associated detailed attachment):
•
•
•
•
PDF bill attachment - price >0
CSV support bill attachment - price >0
PDF bill attachment - price = 0
CSV support bill attachment - price =0
 The CSV file will show cases when Imbalance Price is different from the
Remuneration Price.
