2 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) ESTABLISHMENT OF REGULATED RATES (SERVICE FEES) IS ONE OF THE MAIN FUNCTIONS OF PSRC. ORDER OF ESTABLISHING AND REVISING RATES, AND CALCULATING THE RATE METHODOLOGY SHALL BE DEVELOPED AND APPROVED BY THE COMMISSION. 2

3 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Establshed rates shall enter nto force after thrty days from the date the decson s made. Valdty perod of the rates can not be less than 6 months, except the cases, when: a) A lcensee breaches condtons of the lcense for actvtes, b) A new decson s made by the Commsson on establshng a new rate based on a court s decson on judcal appeal of the rates establshed. Commsson may establsh long term rate for actvtes of a lcensee. The rate establshed may express both a specfc numercal value and a calculaton formula that depends on specfc values. 3

4 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) The establshed rate may be revsed on an ntatve of both a lcensee and the Commsson. The Commsson shall revse the rate (re-approval or change) and make the decson wthn 90 days after recevng a lcensee s applcaton package for revson. The Commsson may revse the rate on ts own ntatve and establsh a new rate n accordance wth the procedure approved by the Commsson on the bass of results of the lcensee s economc actvtes, fulfllment of requrements defned for qualty of nvestment programs and servces provded to the consumers. 4

5 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) A lcensee may sell the natural gas or provde lcensed servces wth a lower rate than the one establshed by the Commsson, provded that: The lcensed actvty s or wll not be mposed to a rsk, It s not amed at acqurng a monopolstc status on the market, The rate s lowered at the expense of a lcensee s proft. In case of such lowered rates, whle establshng new rates, the Commsson does not consder potental losses of the lcensee experenced due to lowered rates. 5

6 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Man objectves of the rate polcy are to: Ensure fnancal sustanablty of companes of the system, Ensure nvolvement of suffcent captal wth a reasonable prce requred for modernzaton and development of the sector, Promote safe and relable provson of gas supply servces by acceptable and compettve rates, Promote effectve use of gas supply servces by consumers. 6

7 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Two groups of rates are appled n the gas supply system: a) For servces provded nternally to each other by companes of the system - regulated rates for transportaton, dstrbuton b) For gas consumers regulated rates for provson of servces 7

8 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Process of developng rates s mplemented n a number of stages. Each stage has ts clear purposes and requres certan calculatons, as well as adopton of prncples (methodology) for mplementaton of those calculatons. 8

9 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Durng the frst stage, volumes of annual returns of the system s companes shall be calculated, whch wll be suffcent for mplementaton of operatonal costs amed at provson of relable, safe and contnuous operaton and ganng a reasonable proft aganst the used captal. For mplementaton of these calculatons, t s necessary to have approved prncples for determnaton of the requred costs and proft. 9

10 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) REGULATORY ՄԻՋԵՎ ՓՈՐՁԻ COMMISSION ՓՈԽԱՆԱԿՄԱՆ (PSRC) AND ՀԱՄԱԳՈՐԾԱԿՑՈՒԹՅՈՒՆ US IOWA UTILITIES BOARD Durng the second stage, the servce provson cost shall be determned for consumers and consumer groups through classfcaton of the costs for varous functons and dstrbuton of the requred revenue among the varous consumer groups. Durng the thrd stage, the rate structures shall be selected and rates shall be calculated. 10

11 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 1. DETERMINATION OF A REVENUE REQUIREMENT 11

12 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) In order to ensure contnuous operaton, the companes must have an opportunty to receve compensaton for the reasonable costs made for a provson of servces. 12

13 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) The annual revenue requrement (RR) of ARMRUSGASPROM CJSC s calculated wth the followng formula: RR = PGC + GTC + OMC + AC + D+ P (1) PGC purchased gas cost wthout a value added tax, GTC gas transportaton cost, whch s the annual cost that s pad by ARMRUSGASPROM CJSC to TRANSGAS LLC for gas transportaton wthn the terrtory of the country, OMC annual operaton and mantenance costs, D deprecaton of fxed assets and amortzaton of ntangble assets T - taxes pad by the company, wthout the VAT and ncome tax, dutes and other mandatory fees envsaged by the legslaton, AP - allowable proft.

14 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) The annual revenue requrement (RR t ) for TRANSGAS LLC s determned wth the same formula wthout purchased gas and transportaton cost components: RR t = OMC + AC+ D + T (2) 14

15 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) The revenue requrement of companes s calculated by takng nto consderaton the actual costs for 12 months wth certan adjustments, whch consder changes to be made n costs and revenues that are already known at the stage of submttng the applcaton and durng valdty of the new rates and whch are measured by reasonable accuracy. 15

16 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) C, V PURCHASED GAS COST PGC C V Cost and volumes of 1000 m3 of gas purchased by ARMRUSGASPROM CJSC durng the year from varous mporters and at dfferent dates. Total amount of gas purchased durng the year that s requred for ensurng an annual consumpton and calculated wth the followng formula: V V V V³ V, V ³ V - volume of gas suppled durng the year to consumers, - Gas losses n the transportaton and dstrbuton systems calculated by methodology approved by the Commsson and own needs. 16

17 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 1.2 GAS TRANSPORTATION COSTS ARMRUSGASARD CJSC that mports, dstrbutes and sells gas wth rates approved by the Commsson, pays to TRANSGAS LLC for provson of gas transportaton and storage servces by ensurng the company s revenue requred that s calculated wth formula (2). 17

18 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 1.3 OPERATION AND MAINTENANCE COSTS Operaton and mantenance costs (OMC) nclude: Salary of operatng personnel, ncludng payments to the socal securty fund, Materal costs requred for operaton, Mantenance/rehabltaton costs that nclude costs of rehabltaton works mplemented both by other contractor organzatons and by own means, Customers servce costs that nclude costs for mantenance of meters, readng of records, bllng, accountng of servce fees and collecton (these costs are typcal for ARMRUSGASARD CJSC that mplements only functons of dstrbuton and customer servces), Admnstratve and general costs, Other operatonal costs whch can also nclude allowable amounts of bad recevables. 18

19 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) The costs that do not relate to the lcensed actvty are not ncluded n the OMC. Separate accountng shall be mplemented n the companes for such costs. Lcensed companes shall mplement accountng n accordance wth the Chart of Accounts and costs allocaton rules approved by the Commsson. Only those costs shall be compensated by rates whch are determned n accordance wth the Chart of Accounts approved by the Commsson. Whle submttng the rate applcaton, the companes shall present the costs for prevous year that are verfed by an audtor, actual (projected) costs for current year and planned costs for accountng year. 19

20 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 1.4 ALLOWABLE PROFIT That amount of the proft shall be consdered as allowable, whch provdes an opportunty for the companes to fulfll commtments related to the captal nvolved for fnancng of assets and does not prevent nvolvement of addtonal own or loan funds requred for development of the company. Allowable proft s calculated as follows: AP = PB x PR where: PB - proft calculaton base, PR - allowable proft rate. 20

21 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Proft calculaton base shall be the cost of the company s net assets: PB = NCEUA - CPNCA - AD + WC, where: NCEUA cost of non current assets that are recognzed as effectve and usable CPNCA cost of consumer pad but uncompensated non current assets, such as the cost of meters and constructons AD accumulated deprecaton, WC amount of workng captal approved by the Commsson. 21

22 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Proft base shall be revsed from tme to tme, but not more than once a year, wth a purpose to consder the followng: Investments made n assets that are recognzed as effectve and usable wthout nvestments pad by the consumers, Allowable deprecaton, Allowed adjustment of the workng captal. 22

23 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Allowable proft rate (PR) shall be establshed equally to the averaged weghted cost of the company s captal, whch shall be the average cost of land and own captal calculated n accordance wth ther share n the captal structure. PR LC r OC r LC OC ë LC, r outstandng loan balance of correspondng loan at the begnnng of year and loan servcng cost (n unt parts) ՍԿ, r ս cost of own captal at the begnnng of accountng year and ts reasonable rate of the allowable proft (before taxaton). 23

24 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 1.5 DEPRECIATION Deprecaton costs shall be estmated by a lnear methodology based on the ntal (acquston) cost of effectve and usable assets and useful servce lfe. If the fxed assets are used wth low use coeffcent or capacty wth a small number of use hours, the Commsson shall have the rght to apply justfed lower coeffcents for ther values/costs. 24

25 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Costs analyss of the company and dstrbuton of costs dependng on the type of lcensed actvtes, types of the costs and consumers group shall be the next stage n the process of developng the rates. One of the purposes of the prcng s to establsh such rates that reflect costs made by the company for servces provded to varous consumers and consumer groups. 25

26 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 2. COST ANALYSIS 26

27 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) By means of costs analyss, a share of varous consumer groups n total costs shall be determned and costs shall be dstrbuted among the consumer groups. Cost analyss shall consst of the followng steps: 1. Functonalzaton of costs, 2. Classfcaton of costs, 3. Classfcaton of consumers, 4. Determnaton of dstrbuton coeffcents and dstrbuton of costs. 27

28 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 2.1 Functonalzaton of costs ARMRUSGASARD CJSC has three functonal areas of actvty: mport, dstrbuton of gas and regulaton of the system. Each component of the company s costs shall be dstrbuted among these three functonal areas. 28

29 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 2.2 Classfcaton of Costs Costs are classfed n the followng groups: fxed, varable and consumer servce costs. Fxed costs are those costs that are made by the company rrespectve of the volume of gas suppled and number of consumers. These are mostly costs of servcng and mantanng the fxed assets of the company and shall be subject to compensaton rrespectve of the volume of gas suppled. Varable costs are those costs that change dependng on the volume of gas suppled. These costs nclude the cost of gas suppled and some other cost that depends on quantty of gas (such as costs for bad recevables wrte-off) Consumer servce costs are those costs that are drectly lnked to servcng of consumers. These nclude costs for readng of meters, bllng, collecton and accountng of the fees, etc., as well as costs of operaton of the meters. 29

30 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 2.3 Classfcaton of consumers Rates dfferentaton may be done based on the capacty requred, volumes, tme of consumpton, and connecton condtons. Dfferentaton shall be mplemented by means of classfyng consumers n the groups. Each consumer group shall consst of the consumers wth smlar consumpton characterstcs, whose gas supply and servcng create more or less same prce load for the system. Economc ndcators can be also used besde the above descrbed techncal ndcators for consumer classfcaton. These nclude such ndcators as value of the servce, prce elastcty, exstence of alternatve opton, compettveness of the servce. 30

31 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Followng classfcaton of consumers s proposed based on the above descrbed: 1. Populaton (household consumers) 2. General busness consumers, 3. Compressed natural gas supplers, 4. Thermal power plants, 5. Heat supply, 6. Large ndustral consumers. 31

32 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 2.4 Dstrbuton of costs At the next stage of analyss, the classfed costs shall be dstrbuted among the consumer groups. Ths dstrbuton shall be mplemented by coeffcents whch shall be determned n a way that, to the extent possble, reflect the reasons for cost causaton from consumer groups. 32

33 K K N N N N ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Dstrbuton of fxed costs shall be mplemented n accordance wth the upper margn /peak/ of volume of own consumpton by a separate consumer group, rrespectve of tme when the consumpton takes place. Ths method of dstrbuton s called a nonconcdent method and s based on a peak consumpton when dstrbuton s mplemented at the moment of maxmum consumpton n accordance wth consumpton by dfferent consumer groups. 33

34 K N N N N ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Dstrbuton coeffcents shall be determned wth the followng formula: K N N N where: K N - dstrbuton coeffcent of fxed costs of consumer group, N - maxmal daly consumpton of consumer group. 34

35 K K N N N N ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Dstrbuton of varable costs shall be mplemented proportonally to the volume of annual consumpton by consumer groups. where: K V V V K V - dstrbuton coeffcent of varable costs of consumer group, V - annual consumpton of consumer group. 35

36 K K N N N N ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Dstrbuton of consumer servce costs shall be mplemented n the gven consumer groups proportonally to the number of consumers. Consderng that provson of servces to the consumers ncluded n varous consumer groups creates varous costs n the company and one nhabtant s consdered as a unt, gven coeffcents are appled, whch, to a certan level of accuracy, reflect those dfferences. 36

37 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Based on the above, coeffcents of dstrbuton of consumer servce costs shall be determned wth the followng formula: where: K n n n n - number of customers of consumer group, - gven coeffcent of one customer of consumer group, whch shows what s the approxmate number of resdent-supplers that can be served by the averaged servce cost of one customer of that group. 37

38 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Dstrbuton of classfed costs on the bass of dstrbuton coeffcents shall be mplemented wth the followng formulas: where: C, C, C N V n C C C N K K N C N V V C V K n n C n - fxed, varable and consumer servce costs approprately, C, C, C N V n - share of approprate costs compensated by consumer group. 38

39 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 3. SELECTION OF THE TYPES AND STRUCTURES OF RATES FOR GAS SUPPLY SYSTEM AND CALCULATION 39

40 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) 3.1 TRANSPORTATION RATE The transportaton rate shall be establshed by TRANSGAS LLC for servces of gas transportaton and storage. The company provdes servces to ARMRUSGASARD CJSC by transportng gas mported by latter from the border up to the dstrbuton lmts. The same servces wll also be provded to other lcensees who mport gas for own needs and exportng. 40

41 ՀՀ ՀԱՆՐԱՅԻՆ ԾԱՌԱՅՈՒԹՅՈՒՆՆԵՐԸ (PSRC) Costs necessary for operaton of gas transportaton system under the condtons of absent lnear compressor statons do not depend on quantty of gas transported and are consdered as fxed capacty costs. A part of costs for gas storage can be consdered as drectly proportonal to the amount of gas stored (for example, cost of gas consumed for operaton of compressors or fnancal costs that relate to gas stored). However, as the transportaton company does not own that gas, these costs are compensated at the expense of gas owners and are not ncluded n the requred revenue of the transportaton company. 41

Monthly fees of the gas transportaton clents shall be consdered as fxed values whch equal to: MF t = R t *Q max These fees do not depend on volume of gas transported durng that month. Maxmum daly consumpton of gas shall be determned by the Clent s meter based on measurements conducted n advance. If no such measurements were conducted, then t can be determned by dvdng the consumpton durng the overloaded wnter month by number of days of that month. In case of lack of even such data, the maxmal consumpton can be determned by capacty of lmtng 43 devces.
