INTRODUCTION

The ERP Exam is a practice-oriented examination. Its ques-

tions are derived from a combination of theory, as set forth

in the core readings, and “real-world” work experience.

Candidates are expected to understand energy risk man-

agement concepts and approaches and how they would

apply to an energy risk manager’s day-to-day activities.

The ERP Examination is also a comprehensive examina-

tion, testing an energy risk professional on a number of risk

management concepts and approaches. It is very rare that

an energy risk manager will be faced with an issue that can

immediately be slotted into just one category. In the real

world, an energy risk manager must be able to identify any

number of risk-related issues and be able to deal with them

effectively.

The ERP Practice Exam 1 has been developed to aid

candidates in their preparation for the ERP Examination in

November 2011. This practice exam is based on a sample

of actual questions from the 2009 ERP Examination and

is suggestive of the questions that will be in the 2011 ERP

Examination.

The ERP Practice Exam 1 contains 60 multiple choice

questions. Note that the 2011 ERP Examination will consist

of a morning and afternoon session, each containing 90

multiple choice questions. The practice exam is designed to

be shorter to allow candidates to calibrate their prepared-

ness for the exam without being overwhelming.

The ERP Practice Exam 1 does not necessarily cover

all topics to be tested in the 2011 ERP Examination. For

a complete list of topics and core readings, candidates

should refer to the 2011 ERP Examination Study Guide.

Core readings were selected in consultation with the Energy

Oversight Committee (EOC) to assist candidates in their

review of the subjects covered by the exam. Questions for

the ERP Examination are derived from these core readings

in their entirety. As such, it is strongly suggested that candi-

dates review all core readings listed in the 2011 ERP Study

Guide in-depth prior to sitting for the exam.

Suggested Use of Practice Exams

To maximize the effectiveness of the practice exams, candi-

dates are encouraged to follow these recommendations:

1. Plan a date and time to take the practice exam.

Set dates appropriately to give sufficient study/review

time for the practice exam prior to the actual exam.

2. Simulate the test environment as closely as possible.

• Take the practice exam in a quiet place.

• Have only the practice exam, candidate answer

sheet, calculator, and writing instruments (pencils,

erasers) available.

• Minimize possible distractions from other people,

cell phones, televisions, etc.; put away any study

material before beginning the practice exam.

• Allocate 2 minutes per question for the practice

exam and set an alarm to alert you when a total of

120 minutes have passed (or 2-60 minute sessions

with a break in between to simulate the actual exam

conditions). Complete the entire exam but note the

questions answered after the 120-minute mark.

• Follow the ERP calculator policy. Candidates are only

allowed to bring certain types of calculators into the

exam room. The only calculators authorized for use

on the ERP Exam in 2011 are listed below, there will

be no exceptions to this policy. You will not be allowed

into the exam room with a personal calculator other

than the following: Texas Instruments BA II Plus

(including the BA II Plus Professional), Hewlett Packard

12C (including the HP 12C Platinum and the Anniversary

Edition), Hewlett Packard 10B II, Hewlett Packard 10B II+

and Hewlett Packard 20B.

3. After completing the ERP Practice Exam 1

• Calculate your score by comparing your answer

sheet with the practice exam answer key. Only

include questions completed within the first 200

minutes in your score.

• Use the practice exam Answers and Explanations to

better understand the correct and incorrect answers

and to identify topics that require additional review.

Consult referenced core readings to prepare for

the exam.

• Remember: pass/fail status for the actual exam is

based on the distribution of scores from all candi-

dates, so use your scores only to gauge your own

progress and level of preparedness.

Explanations



1. An electric power generator is offering the following four separate bids:

• 50 MW at USD 20 per MW• 100 MW at USD 25 per MW• 150 MW at USD 30 per MW• 250 MW at USD 40 per MW

What would the market clearing price of electric power be if demand is 175 MW?

a. USD 40.00/MWb. USD 26.25/MWc. USD 32.72/MWd. USD 30.00/MW

Correct answer: a

Reading reference: Making Competition Work in Electricity, Hunt, Chapter 2, p. 170.Explanation: Answer a is correct. Use the price quoted for 250 MW: apply this amount (USD 40) to anydemand level between 150 and 250 MW.

2. Devon is interested in creating a synthetic commodity by combining a forward contract with a zero-coupon bond. What is the payoff required on the zero-coupon bond if the annual risk-free interest rate on a continuous basis is 2% and the price of the commodity forward contract at time 0 is F0,T = USD 150 (where T = 1 year)?

a. USD 147 b. USD 150c. USD 153d. USD 156

Correct answer: b

Reading reference: Fundamentals of Derivatives Markets, McDonald, Chapter 6, p.171.Explanation: Answer b is correct because, in creating a synthetic, we enter into a commodity forward con-tract and purchase a zero coupon bond equaling e-rt* F0,T, this value is USD 147. The payoff is USD 150. Thetotal payoff in formula form is: ST — F0,T + F0,T, or the payoff on the forward + the payoff of the zero bond.Answer a is incorrect because it is the investment, at time 0, in the zero bond.



3. The Senior Management of Cristal Crude Refinery is planning to build a new refinery complex in Indonesia that includes a coker. Which of the following is true about the new refinery?

a. The refinery is a hydroskimming refinery.b. The refinery is classified as a simple refinery.c. The refinery is best suited for processing heavy crude oil.d. The refinery will produce nearly as much residual fuel as gasoline.

Correct answer: c

Reading reference: Petroleum Refining in Nontechnical Language, 3rd Edition, Leffler: Chapter 20.Explanation: The presence of a coker defines this as a “very complex” refinery; very complex refineries usuallymake their best margins in processing heavy crude, which the coker allows them to break down into more desir-able light petroleum products. Very complex refineries produce little or no residual fuel oil. By comparison,hydroskimming refineries are classified as “simple refineries” that do not include cokers and usually cannot prof-itably refine heavy crude. Since you know your refinery includes a coker, this means that answer b is correct.

4. Which of the following statements regarding the transportation of petroleum products is correct?

a. Natural gas liquids like ethane, ethane-propane mixtures and LPGs are commonly transported by dedicated pipeline.

b. Contamination is usually an issue when butane is transported via the same pipeline as gasoline and diesel.c. Ethane-propane mixtures are seldom transported via pipeline.d. Natural gasoline is typically transported through its own dedicated pipeline.

Correct answer: a

Reading reference: Fundamentals of Natural Gas Processing, Kidnay and Parish, Chapter 12, p. 261.Explanation: Answer a is correct; LPGs are typically transported through their own product-specific pipelines.



5. Which of the following best describes a royalty payment?

a. An amount equal to a percentage of the value of production paid by the holder to the State in cash or in kind.

b. An amount paid by the contract holder to an independent agent for the right to exploit an asset. c. The money collected by the site inspector. d. A tax on production volume, independent of profits.

Correct answer: a

Reading reference: Oil, Gas Exploration and Production, Institut Francais: Chapter 3, p. 198-200.Explanation: A royalty is an amount equal to a percentage of the value of production, paid by the holder tothe State in cash or in kind. It is effectively a tax directly proportional to the value of production, that is, a taxon turnover, and independent of profits. The amount of the royalty depends not only on the percentageapplying, but also on a number of other parameters which must be carefully specified.

6. Which of the following energy forward contracts will have the greatest mark-to-market sensitivity to a single-day price spike created by an unplanned outage at a large generation plant during the delivery period?

a. 5 x 16 contract for a weekb. On-peak contract for delivery over the entire monthc. Round-the-clock contract for delivery over a two-month periodd. A 5 x 8, 2 x 2 4 calendar year contract

Correct answer: a

Reading reference: Energy Risk, Pilipovic: Chapter 7, p. 173-179.Explanation: A forward contract for delivery over a number of days is valued as a weighted average of thedaily forward prices, be it the on-peak, off-peak, or round-the-clock prices given the contract specifications.Hence, a price spike expected to occur for just one of the days in the period will have the greatest impact onthe shorter time period of delivery. That would make answer a the best answer above. Additionally, on-peakmarkets (5 x 16) tend to be more volatile than the round-the-clock markets (7 x 24), which further tend to bemore volatile than the off-peak markets (5 x 8,2 x 24). Hence, in this regard, a is also the best answer.



7. Heinz provides risk management support to a multinational energy trading desk. His primary responsibility is to inform the Chief Risk Officer about derivatives trades executed each day along with all trader risk limit exceptions. Which of the following risk control categories best describes Heinz’s primary responsibility?

a. Risk Reportingb. Risk Review c. Risk Assessmentd. Risk Control

Correct answer: a

Reading reference: Energy Markets: Price Risk Management and Trading, Tom James; Chapter 10, p. 183-84.Explanation: Reporting derivatives positions to upper management is a duty that falls under the reporting(communications) category of risk control; it is an important aspect of risk management because if uppermanagement is not informed of derivative usage the effects on the company can be devastating. Dailyreporting of derivative positions is not the same as an in-depth internal review of a company's finances or anaudit, thus b is not the correct answer; nor do the reporting duties fall under the risk assessment or manage-ment control categories.

8. Jim Johnson is studying issues associated with electricity options. Which of the following statements regarding electricity options is correct?

a. Option models (i.e. Black-Scholes) can be modified to handle electricity as well as financials b. The use of convenience yield compensates for electricity price spikesc. Asian options are popular among electricity risk managers because of to their averaging featured. The “no-arbitrage” argument can be applied to electricity in order to value derivatives

Correct answer: c

Reading reference: Fundamentals of Electricity Derivatives, Kaminski, Chapter 2, p.64.Explanation: Answer c is correct — according to the authors Asian options are gaining in popularity amongelectricity managers for this reason.



9. A power plant enters into a natural gas contract that has a take-or-pay value of 85% and a swing value of 20%. If the contract specifies delivery of 120 MWh of natural gas equivalent, what is the minimum amount of gas that must be purchased under the terms of the contract?

a. 24 MWhb. 96 MWhc. 102 MWhd. 120 MWh

Correct answer: c

Reading reference: Managing Energy Risk: An Integrated View on Power and Other Energy Markets, Burger,Graeber, and Schindlmayer, Chapter 4, p. 166-177.Explanation: The take-or-pay percentage refers to the percentage of the contract that must be paid forwhether the importer wants to take delivery of the gas or not. For this contract, the minimum that must bepaid for is 85% x 120 MWh = 102 MWh.

10. Consider the delta profile for at-the-money European call forward options on NYMEX crude oil. What is the approximate delta value when the strike price is close to the forward price?

a. 0.00b. 0.25c. 0.50d. 1.00

Correct answer: c

Reading reference: Energy Derivatives: Pricing and Risk Management, Clewlow and Strickland; Chapter 9, p. 166.Explanation: Answer c is correct. For at-the-money options, where the strike price is close to the forwardprice the delta is approximately 0.5.

11. Which of the following is NOT a method for managing credit-risk exposure within energy markets?

a. Clearing OTC energy derivativesb. Obtaining credit risk insurancec. Purchasing commodity forward contractsd. Securing a financial guarantee via an Irrevocable Standby Letter of Credit

Correct answer: cReading reference: Energy Markets: Price Risk Management and Trading, James: Chapter 16, p. 319-21.Explanation: Methods for managing credit-risk exposure include: master netting; collateralization; financialguarantees; credit insurance; credit derivatives; assignment; and clearing OTC energy derivatives. The purchase of commodity futures is a hedging strategy.



12. Karachaganak, Kazakhstan is one of the largest gas condensate fields in the world, with proven reserves of 1.9 billion barrels of oil and 13 trillion cubic feet of gas. In 2004, the field produced about 220,000 barrels of oil and 1.3 billion cubic feet of gas per day. What is the producing gas-oil ratio?

a. 4,300b. 5,909c. 6,842d. 7,523

Correct answer: b

Reading reference: Norman J. Hyne. Nontechnical Guide to Petroleum Geology, Exploration, Drilling, andProduction, 2nd Edition (Tulsa, OK: PennWell, 2001): Chapter 1, p. 11.Explanation: Answer B is correct. The definition of producing gas-oil ratio requires gas production (in cubicfeet) to be divided by oil production (in barrels). Thus, GOR = (1,300,000,000 cf)/(220,000 bbl) = 5,909.Note that the gas-oil ratio of the proved reserves is computed as (13 Tcf)/(1.9 Bbbl) = 6,842 which denotes afield with oil (condensate) and gas production.

13. LNG suppliers must assure the quality of the gas from their LNG terminals in order to fulfill which of the following specifications?

a. It is characteristic of the gas as it came from the reservoir.b. It meets the seller’s specifications.c. It is free of methane.d. It is consistent with the requirements of downstream gas customers.

Correct answer: d

Reading reference: LNG: A Nontechnical Guide, Tusiani and Shearer, Chapter 7, p. 180.Explanation: Answer d is correct. The quality of the gas that comes from an LNG import terminal must beconsistent with the requirements of downstream gas customers or meet the specifications of the intercon-nected gas transmission lines, which vary by region and by country.



14. Two manufacturing plants — Factory Alpha and Factory Bravo — are told by the government they each need to reduce their greenhouse gas emissions. The target reductions and costs for each factory to meet this goal are shown in the table below.

Alpha Bravo

Required emissions reductions 10 tons 10 tons

Cost of emissions reductions USD 120 per ton USD 40 per ton

Total cost of reductions USD 1,200 USD 400

Under an emissions trading scheme, Factory Alpha can pay Factory Bravo to reduce its emissions by an addi-tional 10 tons, in effect, buying the needed emissions credit from Bravo.

What will Bravo’s final emission reduction cost be if it charges Alpha USD 600 for the emissions credit?

a. USD 200b. USD 600c. USD 800d. USD 1,000

Correct answer: a

Reading reference: Energy and Emissions Markets: Collision or Convergence?, James and Fusaro; Chapter 3,p. 31-32.Explanation: By making the deal with Factory Alpha, Factory Bravo’s total cost of reductions will be USD 200(answer A). Bravo will now have to reduce their emissions by 20 tons, at USD 40 per ton; this will cost BravoUSD 800. Bravo will receive a payment from Alpha of USD 600, making their final costs USD 200 (800 — 600 = 200).



15. A trader at XYZ Bank has been asked by a client who is a petroleum refiner client to quote the price on a 3-month crude oil forward contract. Given the following forward curve and discount factors for crude oil, calculate the price of the 3 month forward contract.

Contract Price Discount FactorJan Contract USD 79.10/bbl 0.95Feb Contract USD 85.60/bbl 0.92Mar Contract USD 83.90/bbl 0.88

a. USD 80.37b. USD 82.81 c. USD 75.91d. USD 90.40

Correct answer: b

Reading reference: Markus Burger, Bernhard Graeber, and Gero Schindlmayr. Managing Energy Risk:Integrated View on Power and Other Energy Markets (West Sussex, England: John Wiley & Sons, 2007):Chapter 2, p. 50.Explanation: Answer b is correct, the equation is as follows:

16. You have been asked by your supervisor to hedge a daily power option. Which is the most appropriate contract to use to hedge the daily option?

a. Daily forward contractb. Daily futures contractc. OTC swap contractd. Balance-of-the-month contract

Correct answer: d

Reading reference: Fundamentals of Electricity Derivatives, Kaminski: Chapter 2, p. 60, 70.Explanation: Most power markets, except perhaps the Nord Pool, do not have liquid markets for daily forward or futures contracts, so it is best to use a balance-of-the-month contract as a surrogate for daily forward/futures contracts to hedge daily options. The balance-of-the-month price is the price of power delivered every day from today until end of current month.

Q1 Contract = 79.1 * 0.95 + 85.6 * 0.92 + 83.9 * 0.88 227.7290.95 + 0.92 + 0.88 2.75

= 82



17. Which of the following is NOT a disputable point in the performance of an energy commodity contract?

a. Credit ratingsb. Missed deliveries or deadlinesc. Poor commodity qualityd. Default on a debt

Correct answer: a

Reading reference: Fundamentals of Electricity Derivatives, Kaminski; Chapter 12, p. 348-9.Explanation: Answer a is correct. Events and disputes that may come up with a physical contract includeforce majeure, the quality of the commodity being delivered, default on a debt, missed payments, or misseddeliveries. Credit ratings are not created in a contract but rather via third parties.

18. Which of the following statements is/are true about the impact of a “Smart Grid”?

I. A smart grid is a more flexible control system that maximizes the utility of existing transmission assets and delays the need for creating new ones.

II. A smart grid provides better control of the transmission system allowing peaker plants to run during periods of congestion


Correct answer: a

Reading references: US Department of Energy, “The Smart Grid: An Introduction”.Explanation: Answer a is correct: statement I is true because newer technology will allow better rerouting ofexcess power in constrained zones through underutilized transmission assets, while statement II is falsebecause through better utilization of transmission lines during congestion, peaker plants within congestedareas will not have to run just to meet the demand.



19. Which of the statements below is/are an advantage of using Geometric Brownian motion (GBM) to model electricity prices?

I. GBM is an industry standard that can be easily applied for efficient computer simulation II. GBM is a stochastic process that captures the fat tails of price distributions


Correct answer: a

Reading reference: Energy and Power Risk Management: New Developments in Modeling, Pricing, andHedging, Eydeland & Wolyniec: Chapter 4, p. 161-2.Explanation: Answer a is correct, Statement I is the only true statement as per the reading. Statement II isfalse, the principal weakness of GBM (cited on p. 162) is that it does not allow the modeling of fat tails ofprice distributions.

20. Consider the following yields from a simple, complex, and very complex refinery. Each is processing the samesour, heavy crude oil. Based on the output products listed, identify refineries X, Y, and Z by their complexity level.

Product Type\Refinery X Y ZGasoline 60 50 30Jet Fuel 15 15 15Distillate Fuel 25 25 20Residual Fuel — — —Coke 5 — —Refinery Fuel 15 10 8Gain (20) (5) (3)

a. X = simple, Y = complex, Z = very complex b. X = simple, Y = very complex, Z = complexc. X = complex, Y = simple, Z = very complex d. X = very complex, Y = complex, Z = simple

Correct answer: d

Reading reference: Petroleum Refining in Nontechnical Language, 3rd Edition, Leffler: Chapter 20, p. 196.Explanation: d is correct. Refinery complexity refers to the capacity and type of processing units that com-prise a refinery. Refinery complexity will increase when “complex” units with large capacity are added sincethey have greater ability to convert (heavy) crude input into gasoline. For a given grade of crude oil (in thiscase, medium sour, heavy), as the complexity of the refinery increases the gasoline yield increases and theresidual fuel yield decreases (the residual fuel stream is being converted to gasoline).



21. Which facility type is usually considered the least desirable option for underground storage of natural gas because of expense and operational constraints?

a. Depleted oil and gas fieldsb. Aquifersc. Salt cavernsd. Storage tanks

Correct answer: b

Reading reference: Fundamentals of Natural Gas Processing, Kidnay and Parrish: Chapter 12, p. 257.Explanation: B is correct. Aquifers are considered the least desirable underground storage facility for severalreasons — the geology of the aquifer is usually not well understood, infrastructure (wells, pumps, compres-sors, etc.) is unavailable at the site, greater injection pressures mean higher operating cost, gas will need tobe dehydrated, and more stringent environmental regulations will be in place.

22. Consider a power grid where the average heat rate for combined cycle gas turbine plants using natural gas is 8,500 Btu/kWh. The price of natural gas is USD 5.00/MMBtu, and the price of electricity is USD 30.00/MWh. What is the spark spread for this particular power grid?

a. USD 0.0125/kWhb. USD 0.1250/kWhc. USD -0.0125/kWhd. USD -0.1250/kWh

Correct answer: c

Reading reference: Vincent Kaminski (ed). Managing Energy Price Risk, Chapter 3, p.120.Explanation: Answer c is correct, the calculation is as follows:

Spark Spread = Output Price — Input PriceOutput Price = USD 30/MWh x 1MWh/1000kWh = USD 0.03/kWhInput Price= 8500 Btu/kWh x USD 5/1,000,000Btu = USD 0.0425/kWhTherefore, the Spark Spread = -0.0125



23. Ann Kelly buys a long call at a strike of USD 50 and sells a long call at a strike of USD 75. She has purchased which of the following structures?

a. Bull spreadb. Bear spreadc. Participating collard. Participating cap

Correct answer: a

Reading reference: Managing Energy Price Risk, Kaminski, Chapter 2, p.60.Explanation: Answer a is correct since, a bull spread is comprised of buying a long call and selling the upsideby selling a long call at a higher strike price (than the purchased long call).

24. Simone is interested in capturing large price swings in her energy portfolio and decides to use the delta-normalapproach to compute portfolio VaR. The delta-normal approach will be least likely to capture large price changes in which of the following instruments?

a. Futuresb. Forwardsc. Swapsd. Options

Correct answer: d

Reading reference: Energy Risk Management: A Non-technical Introduction to Energy Derivatives, Leppard;Chapter 4, p. 200-205.Explanation: d is correct. Since the delta-VaR method is a linear approximation, it works well only if a givenportfolio is linear or close to linear. The term linear portfolio means that it consists of products that dependlinearly on the risk factor changes. For example, a portfolio consisting of futures, forward and swaps is a lin-ear portfolio. On the other hand, if there are many options in the portfolio it may be far from being linear. Infact, an energy portfolio is expected to be very nonlinear, especially if there are many asset-type deals (e.g.storage, generation, load service, and so on). In this case, linear approximation may be missing big changes inthe portfolio values due to nonlinearity. Hence, delta-VaR method may yield inaccurate results for an energyportfolio consisting of options, since they are not linear instruments.



25. Which of the following statements regarding LNG project costs is correct?

a. The construction of liquefaction plant facilities typically represents the LNG chain’s most significant capital investment.

b. LNG storage tank costs are independent of liquefaction plant location. c. The cost of a liquefaction plant is considered part of the upstream costs.d. One unusual aspect of LNG upstream and downstream development is that future additions to achieve

economies of scale are not planned due to the high cost of building LNG facilities.

Correct answer: a

Reading reference: LNG: A Nontechnical Guide, Tusiani: Chapter 11, p. 301.Explanation: Answer a is correct; it is generally the most significant capital item. Answer b is incorrect, sincestorage tank costs are dependent on location, as well as, total production, distance from market and tanksystem design. The cost of a liquefaction plant are downstream, therefore, answer c is incorrect. Answer d isincorrect, since future additions are anticipated and undertaken if sufficient reserves are present.

26. A major hurricane has shut down drilling activity on hundreds of oil rigs across the Gulf of Mexico. The resulting supply disruption has caused the cash (spot) price of WTI crude to spike above the price of longer dated futures contracts. As a result the WTI contract is said to be trading in _____________.

a. backwardationb. contangoc. short-term disequilibriumd. extreme volatility

Correct answer: a

Reading reference: Risk Management in Commodity Markets, Geman: Chapter 2, p. 11.Explanation: Answer a is correct. A market in backwardation (inverted market) is characterized by cash(spot) prices that are higher than longer dated futures contracts. In contrast, a market in contango is charac-terized by an upward sloping forward price curve.



27. High pressure in subsurface reservoirs can cause a significant volume of natural gas to be dissolved in underground crude oil reserves. Which of the following is the correct term for this build-up of gas?

a. Non-associated gas b. Crude oil gas c. Associated gas d. Free gas

Correct answer: c

Reading reference: Nontechnical Guide to Petroleum Geology, Exploration, Drilling, and Production, Hyne:Chapter 1, p. 11.Explanation: b is correct. Because of high pressure in the subsurface reservoir, a considerable volume of natural gas can be dissolved in crude oil. The formation, dissolved or solution gas/oil ratiois the cubic feet of natural gas dissolved in one barrel of oil in that reservoir under subsurface conditions. The volume meas-urements are reported under surface conditions. In general, as the pressure of the reservoir increases withdepth, the amount of natural gas that can be dissolved in crude oil increases. When crude oil is lifted up awell to the surface, the pressure is relieved, and the natural gas, called solution gas, bubbles out of the oil.The producing gas-oil ratio (GOR) of a well is the number of cubic feet of gas the well produces per barrel of oil. Non-associated natural gas is gas that is not in contact with oil in the subsurface. A non-associated gas well produces almost pure methane. Associated natural gas occurs in contact with crude oil in the subsurface. It occurs both as gas in the free gas cap above the oil and gas dissolved in the crude oil.

28. Which of the following geographic regions is the largest importer of coal?

a. Asiab. Europec. Former Soviet Uniond. North America

Correct answer: a

Reading reference: Producing Liquid Fuels from Coal: Prospects and Policy Issues, Bartis; Chapter 2, p. 6.Explanation: The chief importers of coal are Asian nations bordering the Pacific Ocean, including Japan,South Korea and China, making a the correct choice.



29. Environmental impacts must be considered when evaluating the operating efficiency of an electric generation facility. Using the information below calculate the economic impact of sulfur dioxide (SO2) in the cost of producing each MWh of electricity at Acme Power Generation.

• Heat rate is 8 MMBtu/MWh • SO2 price is USD 600 per ton (2,000 pounds/ton)• SO2 rate is 2.00 lbs per MMBtu

a. USD 2.40 per MWhb. USD 8.25 per MWhc. USD 9.60 per MWhd. USD 4.80 per MWh

Correct answer: d

Reading reference: James and Fusaro, Energy and Emissions Markets, Chapter 3. Explanation: Answer d is correct: 8 * 2 *(1/2000) *USD 600 per ton = 4.80. a is incorrect: 8 *2*(1/4000) *USD 600 = USD 2.40 per MWH (use of 4,000 for lbs per ton), B is incorrect; just a guess, b is Incorrect: use of 1,000 lbs per ton.

30. Andreas purchased a monthly 100 MW on-peak power call option for a month that has 20 business days. The strike price is USD 75/MWh and the premium is USD 5/MWh. What would the gross settlement amount be if Andreas exercised the call option in a month when the average on-peak power price was USD 85/MWh?

a. USD 160,000b. USD 240,000c. USD 320,000d. USD 480,000

Correct answer: c

Reading reference: Managing Energy Price Risk, Kaminski: Chapter 2, p. 46.Explanation: The correct answer is c: the payoff does not include the amount of premium (32,000 MWH xUSD 85 - USD 75). Payout is max (St — k,0) x Q, wherein Q = quantity. a is incorrect, because it includes the pre-mium cost of USD 160,000 (i.e. 32,000 MWH x USD 5). b is incorrect, because it assumes all-hours of 48,000MWH and premium cost (48,000 MWH x USD 85 - USD 75-USD 5). d is incorrect, because it assume all-hoursof 48,000 MWH (48,000 MWH x USD 85 -USD 75). Assumes candidates will know on-peak power call optionmeans for 16 hours per day.



31. Which of the following is an example of basis risk?

a. The risk of a natural gas price spike during peak electricity demand for a gas fired power generation plant.b. The risk of failure to comply with FERC financial reporting regulations.c. The risk that a megawatt of electricity will cost USD 75 in Pennsylvania and USD 82.50 in New York.d. The risk of the inability of a power generation plant to meet demand in a given market.

Correct answer: c

Reading reference: Energy Risk, Pilipovic: Chapter 2, p. 32.Explanation: Answer c is correct. Decentralization introduces geographic “basis risk,” which is unique to ener-gies. In financial markets,today’s dollar is worth a dollar anywhere in the country. In energy markets, pricedepends on location. A megawatt of electricity is priced according to delivery point; the same holds true fornatural gas. Location is a fundamental driver of price. Pilipovic defines “basis risk” as the difference in pricesbetween identical products but in two different markets.

32. Makati and Sons Heating Oil Company expects customer demand to average 2,200 gallons of heating oil during the upcoming heating season. The company sells oil to customers using fixed price contracts and has decided to store enough oil to meet average customer demand of 2,300 gallons. They have also purchased call options to protect against the risk of a much colder than expected winter. What risk is the company primarily seeking to hedge?

a. Volume Riskb. Supply Riskc. Credit Riskd. Location Basis Risk

Correct answer: a

Reading reference: Surviving Energy Prices, Beutel, Chapter 3, p. 29-30.Explanation: Answer a is correct, the heating oil company is concerned about a colder than expected winter,but does not want to be stuck with an excess of inventory. Call options allow the company to purchase addi-tional inventory at a set price should temperatures drop below normal, the options can expire unused if thewinter temperatures are at a normal level.



33. On June 20, Caufield Refining estimates it will need to purchase 40,000 barrels of crude on October 12. Caufield decides to hedge price risk using a November NYMEX futures contract. The November futures price on June 20 is USD 67.00/bbl. On October 12, Caufield is ready to purchase its required crude oil and closes out the futures contract on that day; at this time the spot price is USD 70.10/bbl and the futures price is USD 68.50/bbl. In this scenario, what is the effective price paid per barrel?

a. USD 68.50b. USD 68.60c. USD 70.10d. USD 70.40

Correct answer: b

Reading reference: Energy Markets: Price Risk Management, James: Chapter 13, p. 263.Explanation: The effective price paid (in dollars per barrel) is the final spot price less the gain on the futures, or70.10 — 1.50 = 68.60. This can also be calculated as the initial futures price plus the final basis, 67.00 + 1.60 = 68.60.

34. An oil field estimated to have 50 Mbbl of oil is classified as "P90." What does this classification indicate?

a. That there is a 90% probability the oil field will actually produce more than 50 Mbbl of oil.b. That there is a 90% probability the oil field contains 50 Mbbl of oil.c. That the oil field is 90% depleted.d. That the oil field is determined to contain of 90% petroleum and 10% other material (e.g. natural gas).

Correct answer: a

Reading reference: Oil, Gas Exploration, and Production, Institut Francais; Chapter 3, p. 91.Explanation: In 1997 the Society of Petroleum Engineers (SPE) and the World Petroleum Council formulatedand adopted standards of reserve definitions. Px is defined as a number such that there is an x% likelihoodthat the true reserves exceed Px. For example, if the P10 of a field is 100 Mbbl, there is a 10% probability thatthe actual size of the field exceeds 100 Mbbl. Thus, in this case, P90 indicates a 90% probability the oil fieldwill actually produce more than 50 Mbbl of oil. Other relevant classifications include P95, P50, P10 and P5.



35. Black Gold Co. is a firm specializing in the exploration, acquisition and drilling of new crude oil fields. Based on these activities, Black Gold would best be described as what type of oil operation?

a. Independentb. Integratedc. Speculatived. Wildcat

Correct answer: a

Reading reference: Fundamentals of Oil & Gas Accounting, Wright & Gallun; Chapter 1, p. 1.Explanation: Independent oil and gas companies are typically described as companies primarily involved inexploration and production (E&P) activities, as is Black Gold. Integrated oil and gas companies are usuallyinvolved in at least one downstream activity as well as E&P activities.

36. Which of the following is NOT considered a primary model for electricity trading arrangements?

a. Integrated modelb. Open access modelc. Wheeling modeld. Decentralized model

Correct answer: b

Reading reference: Making Competition Work in Electricity, Hunt: Chapter 7, p. 127-9.Explanation: Answer b is correct, by definition it is not one of the models.

37. You have a portfolio of gas calls and puts that is gamma neutral. Which of the following trading strategies would you implement to make your portfolio delta neutral?

a. Purchase a call option b. Purchase a forward contractc. Purchase either a call or a put optiond. By definition a gamma neutral portfolio is also delta neutral so no action is necessary

Correct answer: b

Reading reference: Clewlow and Strickland: Chapter 9.3, p. 170.Explanation: Answer b is correct. Call and put options have delta and gamma values. So the initial portfoliowould be constructed with calls and puts such that the gamma of the portfolio was zero. There is no guaran-tee that the portfolio would also have zero Delta. Since forward contracts are linear, they only have delta andno gamma. Consequently to ensure that a gamma neutral portfolio was also delta neutral, you would buy orsell the right number of forward contracts to make it delta neutral.



38. Steve Dolan is a power manager at Upstate Electric. He is negotiating a one-day contract to sell 100 MWh of electricity at USD 55/MWh for a 24-hour period and has been asked to calculate the Value-at-Risk (VaR) for the contract. If the daily volatility of electricity prices is 2%, what is the daily VaR on the contract assuming a 95% confidence interval?

a. USD 180b. USD 3,447c. USD 4,330d. USD 5,412

Correct answer: c

Reading reference: Price Risk Management in the Energy Industry: The Value at Risk Approach, Mauro, Section 6.Explanation: Answer c is correct: it is 100 x 55 x 24 x .02 x 1.64 = USD 4,330. Since the contract is for oneday, no time adjustment is needed. Answer a does not include 24 hours in the calculation 100 x 55 x .02 x 1.64= USD 180; b assumes a time adjustment of √365 and does not use 24 in the calculation 100 x 55 x .02 x 1.64x √365 = USD 3,447; d assumes a 98% confidence interval using 2.05 in the calculation 100 x 55 x 24 x .02 x2.05 = USD 5,412

39. Which of the following pricing relationships include the elements of convenience yield?

a. Spot priceb. Expected spot pricec. Strike priced. Forward price

Correct answer: d

40. Wet gas refers to ______________.

a. Gas that has a high moisture contentb. Gas that has a heating value greater than methane.c. Gas that has not been scrubbed of its sulfur impuritiesd. None of the above

Correct answer: b

Reading reference: LNG: A Nontechnical Guide, Tusiani and Shearer, Chapter 3, p. 70.Explanation: Answer b is correct. Wet gas contains a higher composition of higher-chain hydrocarbons suchas propane, butane, and condensates; it has a higher heating value relative to dry gas (methane).

41. Given the following information, how much power capacity (in MWs) would load serving entities in a capacity market be required to purchase to make the building of additional capacity economically viable?

Expected end-user peak load: 100 MWAverage end-user load: 90 MWPercentage reserve margin: 10%

a. 10 MWb. 110 MWc. 100 MWd. 99 MW

Correct answer: b

Reading reference: Making Competition Work in Electricity, Hunt: Chapter 8, p. 166.Explanation: Answer b is correct. Under the capacity obligation system, load serving entities are required topurchase capacity tickets which require them to be able to cover a peak load, plus a reserve. The number oftickets is determined by the formula of peak load, multiplied by (1+x) or the reserve margin percentage. Inthe scenario above, this gives an answer of 110 MW.



42. Which of the following statements is/are true regarding option valuation?

I. The intrinsic value of a call option is greatest when the value of the underlying is equal to the strike price of the option.

II. The time value is the difference between the market quoted premium and the intrinsic value.


Correct answer: b

Reading reference: Energy Modelling: Advances in the Management of Uncertainty, Kaminski (Hampton):Chapter 2, p. 52.Explanation: Answer b is correct: Statement I is false, all else equal, time value will be greatest when theunderlying is trading at the strike price; Statement II is true, by definition the time value of an option is equalto the difference between the market quoted premium and the intrinsic value.

43. Which of the following tests can be used to demonstrate that model errors are unbiased and normally distributed?

I. QQ plotII. R-squaredIII. Autocorrelation test

a. I and IIb. I and IIIc. II and IIId. I, II and III

Correct answer: b

Reading reference: Energy Risk, Pilipovic; Chapter 4, p. 81-84.Explanation: QQ plot and the autocorrelation test are used for testing that errors are normally distributedand that there is no bias from error to error. R-squared measure, on the other hand, measures how well themodel fits the data. Hence, it tells us nothing about the distribution of the errors, but gives us general infor-mation about model performance. Hence, the correct answer is b.



44. Which of the following statements about the storage of natural gas is/are correct?

I. Gas is stored to provide base load storage to meet seasonal demands.II. Gas is stored to provide peak storage to smooth out the demand curve.


Correct answer: c

46. Patel is managing a portfolio with 100 long puts on March peak forward power contracts. If the delta of the put contracts is -0.4, what position in March peak forward power contracts does Patel need to create for the combined portfolio to be delta neutral?

a. Short 40 March Peak Forward contractsb. Long 40 March Peak Forward contractsc. Short 60 March Peak Forward contractsd. Long 60 March Peak Forward contracts

Correct answer: b

Reading reference: Energy Derivatives: Pricing and Risk Management, Clewlow and Strickland: Chapter 9.2, p. 164-7.Explanation: Answer b is correct. A Long Put is really a short position in the underlying, in this case MarchPeak Power. In order to make the delta of the complete portfolio neutral or equal to zero, the position inMarch Peak Forward power contracts needs to be long an enough to offset the -0.4*100 = -40 of the MarchPeak Forward. Consequently, one needs to be long 40 March Peak Forward power contracts.

47. A producer holding a commodity is said to be _____ and could hedge by going _____ a forward contract.

a. Long, long b. Long, shortc. Short, shortd. Short, long

Correct answer: b

Reading reference: Managing Energy Risk, Burger, Chapter 2.Explanation: By definition, someone holding a commodity is said to be long and could hedge by going shorta forward contract.

48. A natural gas-fired power plant uses 15,200 MMBtu of gas to generate 2,000 MWh of electricity. What is the heat rate for this power plant?

a. 0.131 MMBtu/MWhb. 7.6 MMBtu/MWhc. 30.4 MMBtu/MWhd. 7,600 MMBtu/MWh

Correct answer: b

Reading reference: Energy Trading & Investing, Edwards; Chapter 2.2, p. 109.Explanation: The heat rate is determined by dividing the quantity of fuel used by the quantity of power produced, in this example 15,200 MMBtu divided by 2,000 MWh = 7.6 MMBtu/MWh.



49. A 3-month natural gas option with a strike of USD 6.00 on an August contract is trading at a Black-implied volatility of 45%. Another call option with the same contract specifications, with a strike of USD 6.50, is trading at a Black-implied volatility of 50%, producing a volatility smile. Which of the following conclusions can be made given the market information above?

a. The volatility smile tells us that the market is feeling good about the economy and prices are expected to go higher.

b. The different volatilities for the two call options tell us that the lognormal Black model cannot capture the true underlying price behavior with a single volatility measure.

c. A call option with the same contract specifications as the two options in the problem but with a strike of USD 7.00 must therefore be trading at a Black-implied volatility of 55%.

d. The two options should have exactly the same volatility, and therefore this is a case of market arbitrage: the USD 6.00 option is under-priced relative to the USD 6.50 option.

Correct answer: b

Reading reference: Energy Risk, Pilipovic: Chapter 8, p. 232.Explanation: Answer b is correct. Black-implied volatilities for options with the same contract specificationsbut different strikes are necessary to capture the true underlying price behavior and therefore traded optionprices. Black option pricing model assumes log-normal price behavior for the underlying forward prices,which generally does not capture the full spectrum of behavior of energy prices given a single volatilitymeasure. Therefore, the correct answer is b.

50. Consider global proven recoverable coal reserves. Which of the following correctly lists the countries in order of largest to smallest recoverable coal reserves?

a. United States, China, Russia, Australia, Indiab. Russia, United States, India, China, Australiac. United States, Russia, China, India, Australiad. China, United States, Australia, Russia, India

Correct answer: c

Reading reference: “Producing Liquid Fuels from Coal: Prospects and Policy Issues” Bartis, Chapter 2, p. 5.Explanation: Answer b is correct. As compared to oil and gas resources, coal reserves are often character-ized as widely dispersed. On one hand this is an accurate characterization, because major portions of theglobal reserve base are spread among the continents. On the other hand, the eight nations listed in Table 1.1hold 88 percent of reported prove recoverable reserves. Leading the list is the United States, with provenrecoverable coal reserves of about 270 billion tons.



51. Carsten needs to refine petroleum into high octane gasoline. Which process will he use?

a. Horizontal refiningb. Catalytic crackingc. Distillation processd. Vertical hydrolytic emersion

Correct answer: b

Reading reference: Petroleum Refining: Technology and Economics, 5th Edition, Gary: Chapter 1,p. 4.Explanation: Answer b is correct in that it is the technique to create higher octane gasoline. Answers a and crelate to an early method of refining, one that does not produce higher octane gasoline. Answer d is incor-rect because it is a made up term.

52. Which of the following processes refers to the refining of crude oil into separate fractions or cuts?

a. Distillationb. Treatmentc. Blendingd. Conversion

Correct answer: a

Reading reference: Refining: Technology and Economics, 5th Edition, Gary et al, Chapter 1, p. 2.Explanation: Answer a is correct; refining begins with distillation by boiling crude, separating the resultingvapor and cooling it into separate fractions or cuts, creating a range of distilled petroleum products (gasoline, kerosene, naphtha, etc.) in the process.

53. A call swaption is exercised covering 6 months for 100,000 barrels of crude per month. The premium is USD 1.00 per barrel and the strike price is USD 65 per barrel. During the ensuing six months the average price is USD 70 per barrel. What is the net cash flow from the swaption?

a. USD 400,000b. USD 500,000c. USD 2,400,000d. USD 3,000,000

Correct answer: c

Reading reference: Managing Energy Price Risk, Kaminski (Hampton): Chapter 2, p. 78.Explanation: Answer c is correct as per the formula on page 78: USD 2,400,000 = 600,000 x (70-65-1).



54. A call option has a premium of USD 5 and a strike price of USD 28. What is the time value of the call option if the current price of the underlying is USD 31?

a. USD 5b. USD 3c. USD 2d. USD 0

Correct answer: c

Reading reference: Energy Markets: Price Risk Management and Trading, James: Chapter 6, p. 137-8.Explanation: Answer a is incorrect, this is the premium. b is incorrect, this is the intrinsic value. c is correct. It isthe premium less the intrinsic value: intrinsic value = USD 31 - USD 28 = 3, so USD 5 - USD 3 = USD 2, thereforetime value = USD 2. d is incorrect. Only when the premium and intrinsic value are equal is the time value 0.

55. Eloise, ERP, is the risk manager for a large natural gas company. The company uses a VaR model with a 95% confidence level to measure risk exposure and compliance. If Eloise is concerned with the impact of extreme events, she should:

a. Continue VaR testing at the 95% confidence level.b. Move the VaR confidence level up to 97%.c. Move the VaR confidence level down to 90%.d. Implement stress testing to assess the impact of extreme events.

Correct answer: d

Reading reference: Energy and Emissions Markets: Collision or Convergence? James and Fusaro: Chapter 11, p. 194.Explanation: Answer d is correct, VAR measures only possible realities given a set of inputs, it does notaccount for unexpected or “extreme” events.

57. Akiko, an ERP, is pricing a daily transportation deal between Henry Hub and Houston Ship Channel using the mean-reverting Ornstein-Uhlenbeck process to model gas prices. In order to calculate the at-the-money (ATM) implied volatilities for Henry Hub and Houston Ship Channel Akiko will need to do which of the following?

a. Calculate the correct volatilities since the implied volatilities from a Black-Scholes calculation are not the same volatilities used in the Ornstein-Uhlenbeck process.

b. Scale the implied volatilities by 365250 since it is a daily deal.c. Roughly estimate implied volatilities. Nothing else needs to be done.d. Scale the implied volatilities by 250365 since it is a daily deal.

Correct answer: a

Reading reference: Energy Derivatives: Pricing and Risk Management, Clewlow and Strickland: Chapter 3.2.2, p. 41.Explanation: Answer a is correct. Volatility has to be estimated in the context of the stochastic processassumption. The volatility for an Ornstein-Uhlenbeck process has different units to that which is used in theBlack-Scholes model. The volatility for the Ornstein-Uhlenbeck process has units of dollars. The volatilities inBlack-Scholes and Ornstein-Uhlenbeck are not interchangeable.

58. The Cost of Alternative Transportation method of establishing pipeline shipping rates involves comparison against the costs of alternative forms of product transportation such as ship, barge, rail, and truck. Assuming the cost of shipping 1,000 bbl of crude from Tucson, AZ to St. Louis, MO via truck is USD 25/bbl, and by rail is USD 21/bbl, what would be the appropriate charge for transporting 1,000 bbl of crude by pipeline?

a. USD 23.00 — USD 25.00/bbl b. USD 19.50 — USD 21.00/bblc. USD 24.50 — USD 25.50/bbld. USD 21.00 — USD 22.50/bbl

Correct answer: b

Reading reference: Oil and Gas Pipelines: In Nontechnical Language, Miesner and Leffler: Chapter 10, p. 221.Explanation: The cost of alternative transportation method involves understanding the rates charged by thecompeting forms of transportation—ship, barge, rail, truck. The pipeline charge will be set equal to or slightlybelow those rates. Calculating rates using this method can be very favorable for the pipeline owner, especiallyfor long-distance transportation.
