2. Introduction to the Spanish Gas System

With the publication of the Law 34/98 (Hydrocarbons Law), a gradual

liberalization process started, finishing in July 2008 with the end of

the supply by the distributors.

In 2000, the firsts shippers started their operation in Spain. In 2003, domestic consumers were authorized to choose their gas company supplier. At that time, there were two types of gas supply: regulated and liberalized supply.

On the 1st of July of 2008, the supply of gas by the distributors ended, so the liberalization process was 100% completed. The consumers with annual consumption levels and volumes under specific limits are allowed to decide whether they wish to remain on the Last Resort Tariff (TUR), which is a regulated price set by the government, or not. The Supplier Switching Office (OCSUM) was created to ensure the transfer of clients to different suppliers.

The gas sector has been evolving constantly, modifying its rules and adjusting to the ones defined by the European regulations.

IT systems

SL-ATR, Network Third Party Access System is the information system that enables fluid and real-time communication among the parties of the gas system. It supports the complete gas cycle: requests for access, feasibility analysis, contracts, programming, nominations, viability answers, underground storage market rights, measurements, gas quality, allocations, balances and invoicing data.

SCTD, the communication system among distributors and transmission operators, supports the management of the interrelations between distributors with shippers and with the GTS. It covers the processes of contracting, measuring, allocating, accessing to the registry, programming and nominating.

SCTD

MS-ATR, Secondary Market system is an IT application designed to allow the negotiation and registry of secondary market transactions, supporting the sales and purchases as well as the introduction of bids for imbalances management.

MS-ATR

The Detailed protocol PD-04, published the 4th July 2006, formalized the SL-ATR and SCTD as the official communication systems for all agents of the Spanish Gas System.

Technical requirements

SL-ATR upgrades

The modifications in the regulations have direct impact in the SL-ATR. These

modifications often imply releases of new functionalities in the SL-ATR.

For example, during 2012, 17 new developments in the SL-ATR were implemented.

All new functionalities are informed at SL-ATR 2.0 Portal, in the chart “Nuevas

Funcionalidades”

In 2010, DSI launched a new project with the aim of renewing completely the SL-ATR

both from the functional -new processes- and technological point of view –new

platform adapted to the trends of the market. The project is ongoing nowadays.

Currently, 550 users are being communicated through SL-ATR system:

277 shippers

81 transmission operators

64 distributors

128 official organisms and GTS

23


Requesting for access and contracting

The contracting capacity process begins with the submission of a request for accessing to a regulated service in an infrastructure of the gas system. Once a viability analysis is performed both by the operators and the GTS, a contract is signed.

Requests for accessing

•Request to book capacity to the owners of the infrastructure via SL-ATR 2.0. “Accesos y Contratación” module

Viability analysis

•The owner of the infrastructure shall answer the petitioner in the SL-ATR system, either accepting or refusing the request (informing the causes for refusal)

Contracting

•Once the request for accessing is viable, the petitioner

may formalize the contract

•Strandardized contract models are availabe at: http://www.cne.es/cne/contenido.jsp?id_nodo=52&&&keyword=

Operation

The purpose of the technical management of the gas system regulations is to determine the procedures and mechanisms for the technical management of the system, coordinating the activities of all agents of the gas system in order to guarantee the appropriate technical conditions for the system supply continuity, quality and safety, under the principles of objectivity, transparency and non-discrimination.

The Technical Management of the System regulations are to be applied to the Technical Manager of the System, to all agents accessing the gas system, to the owners of the infrastructures and to the consumers.

The NGTS are constantly evolving, being the procedure for their modification stipulated in one of them. The objective of NGTS-12 is to define the procedure for the drawing up of proposals for updating, revision and amendment of the regulations or protocols by the agents of the gas system for the optimum operation of the system.

While the NGTS define the main rules for the operation; the Detailed Protocols provide further definition in those areas where it is necessary.

Enagás GTS has prepared a document that compiles the updated version of the NGTS and PD.

TECHNICAL MANAGEMENT OF THE GAS SYSTEM REGULATIONS (NGTS) AND PROTOCOLS (PD)

Proposals for updating, reviewing and amending NGTS and PD

The Working Group of the Gas System Monitoring Committee for the updating, reviewing and amending the technical management regulations and the detailed protocols is responsible for receiving, analyzing and developing proposals for updating, reviewing and amending the regulations and protocols that come either from the GTS itself or that are sent by other agents of the gas system under the collaboration established in Article 13.1 of Royal Decree 949/2001 of August 3rd.

All agents of the gas system may submit proposals.

If it is considered that the proposal needs a deeper analysis, the President shall propose the creation of a subgroup for its study.

Gas System Monitoring Committee (CSSG)

Its objective is the operative follow-up of the system, the coordination of the different agents, the presentation of information related to operation plans for specific periods (winter action plans) and any other issue that is considered of interest for the system follow-up.

The meetings are held every two months and the attendants shall be representatives of all agents of the gas system, from the DGPEyM (General Directorate of Energy, Policy and Mining), from the Ministry, from the CNMC and depending on the issues, also from the Electric System Operator.

Access request

Viability analysis

Contratacting

The agents should request for access to the owners of the infrastructure informing them of the program and calendar of usage. For transmission and distribution infrastructures, it shall be necessary to inform the exit points. The submission is performed through the SL-ATR 2.0 system

Capacity requests will be treated according to the chronological order of reception of the formal application, except by the requests for accessing to underground storage facilities, which contracting process differ. For infrastructures that might be subject to congestions or for international interconnections, the Ministry may establish different criteria for capacity allocation.

Maximum response time after the formal request:

24 business days

12 business days when the request is for a consumer that, at the moment of sending the request, is consuming gas in similar conditions as the requested ones.

•Standard contract models approved by Resolution due to a proposal from the CNMC are available at: http://www.cne.es/cne/contenido.jsp?id_nodo=52&&&keyword=

Standard contract models

•Contracts are subject to reduction or amendment under certain assumptions.

Reductions or amendments

•The companies requesting access shall furnish the owner of the infrastructure with a guarantee. •Amount: 12 months of the fixed component of the toll applied to the 85% of the contracted

capacity provided that the contract duration is one year or more. •If, after six months from the starting date of supply or from the date of the last modification of

the contracted capacity, less than 80% of the contracted capacity has been used, the contracted capacities will be automatically reduced in the unused percentage. In this case, the guarantee will

be executed in the same portion. •Underground storages capacity: the guarantees of this contracts only take into consideration the

allocated capacity without including the capacity that corresponds to the minimum strategic security reserves. Neither the capacity acquired in the auction nor any capacity acquired by

trading will be considered for the calculation of the guarantee.

Guarantees












38



•Whenever GTS detects a continuous underutilization of the reserved capacity and if maintaining this capacity could provoke the denial to other agents requesting for access due to lack of

available capacity, the GTS shall reduce the reserved capacity in the non used portion, with the loss of the same portion of the guarantee.

•For underground storage capacity contracts, the guarantee will be executed when the gas stock of the shipper in the underground storage during October is less than 80% of the contracted capacity

in that month. The guarantee will be executed in same portion as the non used capacity.

Underutilization

•Short-term: < 2 years •At least 25% of the capacity should be used for short-term contracts

•No shipper shall access to more than 50% of the capacities allocated to short-term contracts •Short-term contracts shall not be requested more than 12 months in advance of the starting

date of the services •They shall not be extended in any case

•Long-term: >=2 years

Short-term and long-term

•The rules for extension might be freely agreed among the parties involved. •Limitation: the notice period should not exceed 6 months

Extension of a contract

According to Royal Decree 949/2001, 3rd August, which regulates the access of third parties to gas infrastructures and that establishes an economic integrated system for the natural gas sector








39

•Sets the the allocation mechanism of the underground storage capacity and creates a capacity market.

•Allocates underground storage capacity to the agents obliged to maintain minimum security stock, including strategic and operative

reserves •In adittion, it states the allocation of a specific amount of capacity to shippers that supply gas to consumers conected to pipelines of less than 4 bar of desing pressure. This type of consumers need more flexibility for the modulation in winter/summer and in the event of cold snaps.

•A portion of the underground storage capacity is allocated by an auction, as market instruments are considered as the most efficient ones for scarce resources.

•Said process is complemented with a secondary market both for the access to underground storage capacity and for the injection and withdrawal rights.

Order ITC/3862/2007

•Defines some aspects related to the underground storage management and establishes the rules for the capacity auction.

Resolution of March 14th 2008 of the

General Secretary of Energy

In 2007 a “renewed” model for the commercial operation and management as a “single underground storage” was established. The model differs from the one used for other infrastructures of the gas system. For underground storages, the allocation, contracting and invoicing processes are performed by GTS.

53

The Technical Manager of the System (GTS) calculates individual and periodical balances for all users of the Gas System


Balances NGTS-07

•Frequency: daily •Daily and aggregated information of the allocations for each user with the best available

information •Useful to identify users that are imbalanced

•Available before 12h of the first day after the gas day

Daily balance

•The adjustments of the daily balance are calculated once the final allocations, the regularizations and differences in measurements are obtained

•The adjustments will be charged applying the same amount on each day of the next month in which they are communicated to the users. Adjustments will take part of the daily balance

Regularizations to the daily balance due to the final allocations

•The operators of the Gas System shall calculate physical balances of the gas that goes through their infrastructures with the aim of guaranteeing the proper operation of the systems, controlling

the losses volume.

Physical balances per infrastructure

54

Any user of the Gas System will be imbalanced when its stock of gas in the system is not within the tolerance levels established by the NGTS


Individual imbalances

•The reference balance for the individual imabalances will be the daily balance

Reference balance

•All imbalances are billed by GTS, except the imbalance of shortfall of LNG in a regasification plant, that is billed by the owner of the plant.

Responsible of invoicing

•Defined in RD-Law 7/2006 •The minimum operative storage included is ½ day of the transmission and distribution

contracted capacity of the transmission network, except for users whose contracted transmission and distribution capacity represents less than the 0,5% of the total

contracted capacity, which will have a right of usage of the operative storage of 1 day of their transmission and distribution contracted capacity.

•Access to the Simulator of operative storage

Right of operative storage (AOC)








http://www.enagas.es/cs/Satellite?cid=1307595832943&language=es&pagename=ENAGAS/Page/ENAG_CapPrincipal







55



When the stock in the AOC is higher than the right of operative storage.

The balance in AOC is calculated for all the contracts of entry capacity to the transmission and

distribution system that the user has.

The imbalance is calculated for each day as:

AOCce = E1*1,1 Tvca + E2 *1,5 Tvca + E3 *10 Tvca

AOCce = Cost for excess in AOC

Tvca = Variable component of the LNG storage fee

E1 = Excess of stock in AOC of less than 0,2 days

E2 = Excess of stock in AOC that is comprised between 0,2 and 0,5 days

E3 = Excess of stock in AOC > 0,5 days

Associated regulation: Resolution of October 18,2007

Excess in AOC










56



Excess in AOC

According to the moving average of 30 days including the present day of LNG stock

for the user or for all users that belong to the same business group.

Excess: the quantity of the moving average that is higher than 15 times the contracted

regasification capacity. For users in which 15 times contracted regasification capacity is

< 300 GWh, the limit will be 300 GWh

GNLce= 2,5*Tvca*E1 + 10 *Tvca*E2

GNLce = Cost for excess of LNG in plants

Tvca = Variable component of LNG storage fee

E1 = Excess of stock of LNG <= 4 days

E2 = Excess of stock of LNG > 4 days

For users that have loaded LNG and that are imbalanced due to LNG excess in plants,

such imbalance will be lessened by an amount equal to the stock loaded in the

month up to a maximum limit of 300 GWh.

Associated regulation: Order IET/2446/2013

LNG excess in plants







57



When the stock of a user in AOC is below zero.

It is calculated daily according to:

Quantity of shortfall * 1,1 * Variable component

of the LNG storage fee

Associated regulation: Resolution of October 18,

2007

Shortfall in AOC

Billed by the owner of the regasification plant.

When the user’s stock in the regasification plant is

below zero.


Quantity of shortfall * 1,1 * LNG storage fee

Associated regulation: Resolution of October 18, 2007

LNG shorfall in a plant

When the algebraic sum of the balances of LNG stock in regasification plants and in the AOC is

negative.


Quantity of shortfall * daily cost of operative stock shortfall (€/kWh/day)

Daily cost of operative stock shortfall (EOcd) = 15% Reference Price for imbalances of operative stock

shortfall

Reference Price for imbalances of operative stock shortfall: arithmetic mean of the last seven available

Operation

Normal Operation

• The gas system is in a Normal Operation situation when the basic control variables are within the normal operation values of the system.

ExceptionalSituation

• (SOE) situation in which it is expected that not all the parameters defining the normal operation are met, but it does not require the declaration of Emergency Situation.

Emergency Situation

•When the gas supply shortage might require the use of strategic reserves or when the security of people, equipements or facilites might be at risk.

SOE: The operation of the system will require a declaration by GTS that should previously be sent to the Ministry, the CNMC and to all operators and users. In case of restrictions to users, the affected Autonomous Communities will be informed.

SOE Level 0: when a situation of shortage of surplus of gas in the system is expected that may affect the Normal Operation, but it is not expected to affect the guarantee, security and continuity of the firm gas supply.

SOE Level 1: when the actions taken in a SOE Level 0 situation are insufficient to get the system back to the situation of Normal Operation.

SOE Level 2: when the actions taken in SOE Level 0 and SOE Level 1 are insufficient to get the system to the situation of Normal Operation.

In an Emergency Situation the Governmet shall establish the conditions to be met for the utilization of the strategic reserves by the users obligued to their maintenance.

61


Access Invoicing

•The Ministerial Orders shall establish the specific values of tolls and levies or a methodology for their calculation. These values are modified annually or when required

due to any cause affecting the system.

Considerations

•To the gas to be exported through a terrestrial international interconnection, it will be applied a factor of 0,7 to the fix component of the conduction distribution and transmission toll 1.3 on force.

No variable component will be applied.

Exports through international interconnection

•Shippers supplying consumers connected to a distribution network that are supplied by a LNG satellite plant have a global discount in the distribution and transmission toll that is equivalent to

the cost of the non-used network. This discount is published annually in the regulation.

Users supplied by an LNG satellite plant

•For these contracts, the reserve capacity component, the fix component of the regasification toll, the fix component of the transmission toll and the fix component of the LNG truck loading toll will

be calculated using the coefficients set forth in the Ministerial Orders (rates for each month and for daily or monthly tolls)

Contracts with duration less than one year

62


Access Invoicing

• The owners of the infrastructures are responsible for invoicing the accesses, with the exception of the underground storage capacity, that will be invoiced by Enagás GTS.

Responsibles for invoicing

•When the invoicing period is not a natural month, the fix component of the transmission and distribution toll or the capacity reserve toll will be calculated multiplying the monthly toll by

the number of days to be invoiced divided by the number of days of the month.

Invoicing period

•The consumption will be divided proportionally to the time each period has been in force, excepting for those consumers having daily measures, that will be calculated according to their

measures.

Invoicing periods having tolls modifications

•Enagás website provides a services simulator that allows users to calculate the tolls and fees of the selected services.
