Thermal Year 2015-2016

Thanks to the development of the new field of San Potito & Cotignola, following its operational start up in May 2013, Edison Stoccaggio will be able in T.Y. 2015-2016 to make available an increased offer of capacities for different storage services. More details about operating conditions and scheduled interventions are available in the "Operation" section, which include the Operation and Maintenance plan 2015/16.

The Overall Space for storage service offered for the T.Y. 2015-2016 is equal to 28.309.000 GJ (equivalent to 743 MSm³ @ PCS 38.100 kJ/Smc)

Just like last year, available capacities and performances are defined on the basis of the results of wells performances simulations, taking also into account maintenance interventions plan. As a result, adjustment factors, their validity ranges as well as utilization profiles (which determine Injection and Withdrawal performances), may be affected by the actual evolution of the injection / withdrawal cycles.

Please note that T.Y. 2014/15 Customers will be able to offer their own gas on the platform PB-gas managed by GME only with reference to "Locational market - sector G-1" (Gas Day - 1). As a result of the persisting lack of an agreement between the concerned operators, today it is not possible for Edison Stoccaggio Customers to offer their own gas on the platform PB-gas with reference to sector G+1 (Gas Day + 1).

Any changes will be promptly notified to the User pursuant to what provided under Chapters 2 and 13 of the Storage Code.

A more detailed description of the services, System features, Parties’ rights and obligations and Annual Plan of interventions, please refer to the following documents:

The Overall Space for storage service offered for the T.Y. 2015-2016 is equal to 28.309.000 GJ (equivalent to 743 MSm³ @ PCS 38.100 kJ/Smc) and it is divided as follows:
Overall Space (GJ):
Sstr (**)	5.334.000
Sbil	115.000
Sm (*)	-
Smod (***)	22.860.000
Total Space	28.309.000

Overall Injection capacity (CI) associated by Edison Stoccaggio to offered Overall Space is 210.650 GJ/g (equivalent to 5,53 MSm³/g@ PCS 38.100 kJ/Smc ), and it is divided among different services as follows:
Injection availability (GJ/g):
CIbil	1.100
CIm (*)	-
CImod	209.550
Total Injection Capacity	210.650
CI during withdrawal period	20.000

Overall Withdrawal Capacity (CEmax) associated by Edison Stoccaggio to offered Overall Space, is 229.700 GJ/g (equivalent to 6,03 MSm³/g@ PCS 38.100 kJ/Smc ), and it is divided among different services as follows:
Withdrawal availability (GJ/g):
CEbil	1.100
CEm (*)	-
CEmod(¹)	228.600
Total Whitdrawal capacity	229.700
(¹) Maximum value

During the end-of-cycle periods ("periodi di spalla"), Edison Stoccaggio will make available the following capacities:
Period		Withdrawal	Injection
From	To	[GJ/g]	[GJ/g]
01/04/2015	15/04/2015	20.000	53.340
15/10/2015	21/10/2015	8.001	-
22/10/2015	31/10/2015	57.150

(*)Available capacities for Hydrocarbon service have been assumed equal to those allocated in 2014, i.e. equal to 0..
(**) In compliance with AEEG deliberation 149/2012/R/GAS, Edison Stoccaggio does not perform any allocation procedure for strategic storage services, but makes available a volume of 5.334.000 GJ (equal to 140 MSmc @ 38100 Kj/Smc) as strategic reserve
(***) The space for modulation services will be allocated pursuant to art. 2 paragraphs 2 and 3 of D.M. 6 February 2015

As provided for in AEEGSI deliberation 297/2012/R/GAS and under the assumption that the offered space for storage services in T.Y. '15/'16 is entirely allocated, the maximum daily volumes that can be injected / withdrawn at the entry / exit point of the transport network interconnected with the storages for the period April 2015 - March 2016 are published by Edison Stoccaggio here below:

Network Exit point to storages: 5,53 MSm³/g equal to 210.650 GJ/g (@ PCS 38.100 kJ/Sm³)

Network Entry point from storages: 6,03 MSm³/g equal to 229.700 GJ/g (@ PCS 38.100 kJ/Sm³)
