    The Companys load forecast indicates that the region is expected to have future annualincreases in energy demand of approximately 2.02% and peak load of approximately 2.01%[2]. At present, the Company has three options for meeting future increases in energy and peakdemand including supply-side resources, demand-side resources, and market purchases. TheCompany also remains committed to meeting its renewable energy and energy efficiency goalsin a cost-effective manner.

    The Company uses PJMs reserve margin guidelines in conjunction with its own loadforecast. The decrease in reserve margin from the previous study is the result of a slightincrease in the PJM/World load diversity.

    Estimated Customer Growth & GWH Consumption:

  • 7/27/2019 Rate Request filing

    7/33

    Taking into account the increase in the Industrial load in GWH, it is decided that a Nuclear plantbe established at the Virginia City Hybrid Energy Centre(VHEC) which has an average life of 60years and an estimated capacity of 585MW. Since it will operate to the base load the capacityfactor is assumed to be 55% and the time of operation is calculated using the formula

    Time of Operation(Days)=Capacity Factor*(8760), therefore the fixed O&M and variable O&Mcost are determined based in the document 8 cited in reference. Therefore it is estimated thatthis establishment will serve our industrial load and offset the deficit energy usage by 60%.The remaining 40% is compensated by setting up a Gas Turbine plant at Brunswick countyhaving a demand capacity of 350MW. This is set up with an intention to serve our increase insummer peak as gas fired plant take less time to attain steady state operation. The expensesrelated to it are estimated in the same way mentioned for Nuclear Plant. It is assumed that theGas Turbine plant will last for 25 years and the capital cost related to it is depreciated linearly.As per our estimation this plant will compensate for 30% increase in the GWH consumption ofour total energy demand. This will primarily supply our ever-growing commercial andresidential classes.

    The company has adapted to the changing regulatory environment and now with an intentionto serve the REPS it has decided to establish a Biomass Plant at Gloucester County. With acapacity of 100MW it is expected to operate at 50% capacity factor serving 9.4% of ourincreased energy demand. The deficit demand of 0.6-1.00% is to be bought from the PJMsenergy market. This is a drastic reduction compared to the figures from 2010 where 3% of thedeficit energy demand was bought. The company believes that this forward step will eventuallylead to the self sustainable future and secure its ability to serve the customers.

    Baseload/Peak:The graph below depicts screening curves for a variety of plants[7]. According to each plants

    fixed (y-intercept) and variable costs (slope), the best economical use for that plant can bedetermined.

    In order to determine which plants should compromise the baseload and the peak power, thecosts required at each hour for each plant should be considered. The Combined Cycle andCombustion Cycle are the cheapest plants to run at ~2000 h/yr. These plants will provide thepeak demand, since they run economically for only a portion of the total year. The Oil/GasSteam may contribute to the peak load if the Combined Cycle and Combustion Cycle plants arerunning at full capacity. As seen on the graph, the Oil/Gas Steam is the most economicalrunning at below ~3000 h/yr. From ~2000 h/yr to ~6000 h/yr, Combined Cycle is the mosteconomical and will provide power to the intermediate load. The baseload power will beprovided by Hydroelectric and Pulverized Coal. Nuclear and Biomass are also good options forbaseload power that are used by Dominion. At above ~6000 h/yr, Hydroelectric and PulverizedCoal become the cheapest plants to run. Since they are the most economical to run for thegreatest number of hours per year, they become the baseload power, which is typically onlyswitched off for maintenance. This information is summarized below.

    The table above summarizes the resources that the company reviewed as part of the evaluationfor plant establishment study. It is evident that the Uranium was the best possible choice toserve the Industrial Customers when long-term benefits were considered.

    TRANSMISSION & DISTRIBUTION:According to the 2011 Dominion IR Reference Book [4], Dominion had 6,300 miles of electrictransmission lines and 56,900 miles of electric distribution lines. In 2011, infrastructureinvestment was $0.5 billion in electric transmission and $0.2 billion in electric distribution,[totalling $0.7 billion. According to the Democratic Policy Committee [5], the cost per mile oftransmission falls between $1.5 to 2 million per mile. Distribution lines can cost from $10,000to $250,000 per mile [6]. Using this information, the miles and cost of infrastructure added in2011 and in previous years are calculated below.

    2011 Infrastructure Previous InfrastructureTransmissionInfrastructure

    250 milesTotal Cost = $500 million(at $2 million per mile)

    6,300 - 250 = 6,050 milesTotal Cost = $12,100 million(at $2 million per mile)

    DistributionInfrastructure

    2000 milesTotal Cost = $200 million(at $100,000 per mile)

    56,900 - 2000 = 54,900 milesTotal Cost = $5,490 million(at $100,000 per mile)

    We have assumed that for every 25 feeders we have a Distribution Substation. the cost statedabove includes all these substations and the equipments associated with it. In the transmission

    sector, the system primarily includes 500 kV lines[19] and a number of 230 kV lines are beingadded in the recent past. We assume for every 150 mile of transmission line a interconnection

    substation is placed. Again the cost presented above has already included these substations.

    BALANCE SHEET EXPLANATIONS:

    Asset Expenditure: [23]Our total asset value of the plants including the transmission and distribution infrastructurecosts we end up with a total asset worth of $45,614 Million. As of 2011 the company had a debtto equity ratio of 1.519 and the total shareholders equity including the retained earnings

    added up to $11,446 Million. The total long term debt was $17,394 Million.

    The expenses for all these activities are reflected in our AFUDC expenses which is accounted asthe other income expense in our income statement.

    Income Tax Expense: For the revenue generated for the year 2010-11 we have assumed a sumof $745 million as our income tax expense [1].

    Debt Amortization: includes the amortization of intangible and acquired assets. As of 30th September 2011, bonds maturing in 2011 add up to $462.5 million [10]. We haveassumed an equal amount to be paid in as amortization for loan for the year 2011. The same isreflected in our income statement.

    Property and other taxes: $554 million is the amount paid by Dominion in the year 2011 asproperty and and other indirect taxes other than income taxes for the utility sector. It includesfees for licenses and other business regulations to government agencies.

    Purchased gas: $1764 million was purchased in the year 2011 for resale by Dominion [1].

    FUEL COSTS:The total fuel cost for year comes to $1103 million. The capacity (MW), capacity factor [2] andtime of operation for each plant were used to find the plant output in MWh. The fuel costs forthe coal, oil/gas, CC, CT, and hydroelectric plants were calculated using the heat rate and fuelcost data below.Typical cost parameters for power plants and fuel types[7].

    Hydroelectric water 0 0

    The cost for uranium (nuclear) fuel was calculated at 0.77 cents per kWh [11]. Biomass fuelcosts were calculated at 9 cents per kWh [12].

    SMART METERS: [26]A small percentage of our total cost includes smart meters. Dominion has been demonstrating

    the benefits of smart metering technology since 2009. To date, we have installed more than100,000 smart meters in portions of Midlothian, Charlottesville, Northern Virginia,Williamsburg, downtown Richmond, and in the Blue Ridge area.

    The smart meter demonstrations help evaluate technologies that can improve infrastructurefor delivery and reliability of electric service, and provide safe, cost effective service to ourcustomers and also to enable a two way communication between the meter and Dominion'selectric distribution system.

    VEHICLE MANAGEMENT: [27]Dominion ensures that its electrical infrastructure can support the expected demand fromelectric vehicles, which have significantly lower carbon intensity than conventionalvehicles.

    It has added the Chevrolet Volt and Nissan Leaf to its vehicle fleet in an effort to educate aboutas well as study the impact on our system. The electric vehicles will help to assess how utilitiescan manage the new technology. The main purpose of these electric vehicles would bedistribution circuit maintenance and meter reading.

    Fewer meter readers means fewer meter reading vehicles, less mileage, and lower insurancecosts.Hence ,Vehicle Management = auto insurance savings + (reduced number of vehicles * annualmiles driven * operating costs per mile)

    LOAD DURATION CURVE

    The load duration curve for Dominion is shown below [2].

  • 7/27/2019 Rate Request filing

    14/33

    Baseload generation consists of coal, nuclear, biomass, and hydro, which have the highest timeof operation of the plants. Below is a breakdown of baseload capacity.

    Rate Schedule:Our Electric Revenue for the year 2011 was $14379 million. keeping that as a basis, the newincome statement for the test period 2012 has been built. This includes the O&M cost for the allthe new plants added and also includes the portion of money allocated for the smart meterinitiative and also the addition of vehicle management. Based on this our test year revenue canup to $13,489 million[20].

    Rate Base:Our rate base calculation is primarily based on the increase in operating revenue required dueto the addition of new plants. It includes the Allowance on working capital and the Net utilityplant available as of 2012 test period. the following were included as a part of the utility plantcost:

    Rate Design:Based on our operating revenue for 2012 test period which came up to $9571.51 [22] for aReturn on revenue of10.55%[22]., we have designed our rate design on the following manner:

    Cost functionalization: [22 sheet Functionalization]We have functionalized all our expenses into the following three broad categories:

    Generation costs Transmission costs Distribution costs.All our O&M costs and Tax expenses and annual depreciation expenses have been

    functionalized within these 3 categories.

    Cost Classification: [22 sheet Costclassification]After functionalizing the cost we have classified the costs in each of the functions based on theimpact that created the cost. Our primary classifiers are shown below within each functions

    Generation costso Demand Related Costso Energy Related Costs Transmission costso Demand Related Costs Distribution costso Demand Related Costso Customer Related CostsWe have distributed our costs in the generation side on 60-40 basis between the 2 classifiers. for the transmission side there is only demand related costs and for the distribution we havedivided it equally(50-50).

    Cost Allocation: [22 sheet Cost Allocation]Based on our classifiers we have decide on 6 allocation factors to allocated costs to teach of ourcustomer classes. All these factors have been assigned weightage primarily based on theelectricity usage pattern of all the customers. Our daily load curve is shown below:

    Our allocation factors are listed below as a part of the classifiers:

    Generation costso Demand Related Costs Average Excess Demand Factor(AED)This factor is based on the excess demand made on the average demand for the class.
