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.

5

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.

Access to the new balancing system(2 of 2)

6

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.

EPSu [PFATT+PDET+PATT]

Calculation of the system's potential exposure to the User (EPSu)(1 of 5)

7

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.

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.

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.

Transportation programs and BalancingIntroduction

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 .

BillingIntroduction

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:

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.

54

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).

55

Gas Month M+1 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.

Blank Tests

While awaiting the availability of the definitive solution, in order to allow Balancing Users to familiarise themselves with the changes introduced by Resolution 45/11, Snam Rete Gas is preparing an application solution which will implement a subset of new functionalities

The application solution will be made available to all active Transport Users for the new 2011-2012 Gas Year

The date set for the start of Blank Tests is 3 October

The duration is expected to be roughly 15 days

The new functionalities will be accessible with the same users existing on the systems already used today (SRG website, Altra Web and Capacity Portal)

Snam Rete Gas will provide a help desk Service to support Users

Snam Rete Gas will shortly send a communication to notify the start of tests and provide operational details
