29 Clean Power / F2006 Call Comparison Terms Clean Power Call F2006 Open Call Variations Eligibility Allows risk transfer & value adds Clean projects only No forest-based biomass fuel Minimum 25 GWh annual firm energy delivery Project specific no risk transfer All technologies allowed Forest-based biomass eligible 10 MW minimum project for large project stream 29

30 Clean Power / F2006 Call Comparison Terms Clean Power Call F2006 Open Call Interconnections CEAP Tariff All Interconnection costs to be paid by BC Hydro (factored in evaluation) Grandfathered process (similar to CEAP) Only Network Upgrades portion of interconnection paid by BC Hydro 30

31 Cost of the Call The Negotiated Settlement Agreement for the F2007/08 Revenue Requirements Application stated: In its next revenue requirement application BC Hydro shall provide its costs of conducting its next energy call at its first workshop for that call. In its 2006 IEP/LTAP decision, the BCUC approved an expenditure of $2,875,000 to undertake and complete the Identification, Definition and Implementation phase work for the Clean Power Call. Budget for F2007-F2009, includes the following: Internal Salaries, Engagement, etc. $2,065,000 External Legal and Other Services $ 810,000 31

32 Possible Process Options Should BC Hydro allow negotiation in the acquisition process? Is all possible value being captured in the acquisitions process for the CPC? Allowing negotiation may require changing from a Call for Tenders process to a structured Request for Proposals process Similar to current Call For Tenders process with some key exceptions: Replacement of tender security with significant participation fees Limited areas for negotiation BC Hydro would potentially only negotiate with a limited number of bidders 32

33 Clean Power Call Evaluation Bill Peterson Principal 33

34 Evaluation Overview What is the process leading to the selection of Tenders for contract award? Risk assessment project development certainty energy delivery certainty Quantitative evaluation convert Bid Price from each Tender into Adjusted Bid Price assemble Tenders into portfolios compute blended Adjusted Bid Prices for each portfolio Selection of optimal cost-effective portfolio, based on blended Adjusted Bid Prices non-price factors including results from risk assessment 34

35 Risk Assessment Objectives Mitigate supply risk to BC Hydro Provide comfort to serious bidders Areas to be assessed will likely include: Development and operating experience Financial capacity and creditworthiness Project development schedule Site acquisition/control Permits First Nations consultation Community consultation Fuel supply 35

36 Risk Assessment Any red flags identified during this phase may be considered during the process of creating the optimal portfolio Sources of information include: Project brief submitted as part of the Tender Other parts of the Tender (except price) Information generally available in the public domain Independent third party advisors Government agencies BCTC 36

37 Quantitative Evaluation Possible differences between Tenders Bid Price structures Product attributes Project locations These differences define the features and hence the value of the product being tendered to BC Hydro Computation of Adjusted Bid Price for each Tender facilitates a fair comparison of Bid Prices between Tenders Adjusted Bid Prices only used for evaluation purposes Payment for actual energy deliveries will be based on the Bid Price, not the Adjusted Bid Price 37

38 Adjusted Bid Price Tendered Bid Price Price Levelization Bid Price Adjustments Adjusted Bid Price Bid Price structures Product attributes Hourly Firm Wind Integration Approved variations, if any Project locations Interconnection and Transmission Adjustments 38

39 Price Levelization Bidders can tender the following different pricing features: COD: 1 November 2010 to 1 November 2016 Term: 15 to 40 years Bid Price escalation: Pre-COD: 0% to 200% of the Bid Price escalates at CPI Post-COD: 0% to 100% of the Bid Price escalates at CPI Nominal $ $/MWh year bid, 0% CPI 40 year bid, 100% CPI 39

40 Price Levelization Levelizing the tendered Bid Price is the technique used to compare different Bid Price structures Levelizing = the conversion of a non-uniform stream of cash flows into a present value (PV) equivalent uniform stream of cash flows Levelized Bid Price = PV cash flow (based on Bid Price) divided by the PV of the energy flow 40

41 Bid Price Adjustments Hourly Firm Hourly Firm Energy Election Levelized Bid Price reduced by a $/MWh amount dependent upon the tendered profile of HLH firm energy over the year Using a recent estimate for BC Hydro s reference price for capacity, the adjustment for a flat profile of HLH firm energy would be approx $3/MWh 41

42 Bid Price Adjustments Wind Integration Wind Integration Adjustment For wind projects, levelized Bid Price increased by a $/MWh amount, to be determined by BC Hydro Recent review of other jurisdictions shows a range of $5 to $15 per MWh 42

43 Bid Price Adjustments - Variations Approved variations, if any Levelized Bid Price may be adjusted by a $/MWh amount, assuming additional value/risk being transferred to BC Hydro can be quantified For example, project is able to provide dispatchable capacity 43

44 Bid Price Adjustments - Location Tenders likely to be located all across the Province Levelized Bid Prices will be adjusted to reflect the costs borne by BC Hydro associated with taking delivery of the energy and moving it through the Distribution (if D-connected) and Transmission systems to the Lower Mainland 44

45 Bid Price Adjustments - Location Costs borne by BC Hydro include: Direct Assignment (DA) and Network Upgrade (NU) costs associated with the interconnection of the Project to the BC Hydro system NU costs associated with the transmission of the energy from the Project through the BC Hydro system to the Lower Mainland Includes Cost of Incremental Firm Transmission (CIFT) on the 500 kv system, and may also include regional cut-planes or other specific system reinforcements Energy losses associated with the transmission of the energy from the Project through the BC Hydro system to the Lower Mainland 45

46 Bid Price Adjustments - Location Project-specific DA and NU costs will be converted to a $/MWh amount, then added to the levelized Bid Price Levelized over tendered EPA Term, then divided by annual firm energy Project-specific energy losses will be converted to a $/MWh amount, then added to the levelized Bid Prices $/MWh adjustment = [ levelized Bid Price +/- other adj ] x [ L / (1 - L) ] Losses are normally positive, but could be negative if there are net line loss savings 46

47 Bid Price Adjustments - Location Estimates for DAs, NUs and losses for each project will come from BCTC (T-system) and BC Hydro (D-system, if applicable) Location adjustments initially done on a standalone basis BC Hydro may request BCTC to conduct special studies of two or more Tenders, to assess impacts on DAs, NUs, and/or losses at a portfolio level BC Hydro may also request BCTC to conduct special studies for Tenders that could be affected by a change to the base case 47

48 Adjusted Bid Price End result is a levelized Bid Price for a clean, seasonal Firm Energy product, adjusted for delivery to the Lower Mainland The following example illustrates how tendered Bid Prices are converted into corresponding Adjusted Bid Prices, for three hypothetical Tenders 48

49 Example Calculation of ABP Assumptions: Tender A Tender B Tender C Bid Price (2008$) $80/MWh $80/MWh $80/MWh Escalation 50% 25% 100% Term 40 years 30 years 20 years Hourly firm No No Yes HLH FE profile N/A N/A Flat Wind No Yes No COD Jan 1, 2011 Jan 1, 2011 Jan 1, 2011 Annual firm 1000 GWh 1000 GWh 1000 GWh Location Central Interior Vancouver Island Peace River DA and NU (BCTC) $2 million/yr $2 million/yr $2 million/yr Losses (BCTC) 10% 5% 15% 49

50 Example Calculation of ABP BP Adjustments: Tender A Tender B Tender C Levelized BP 1 $68.4/MWh $64.8/MWh $80.0/MWh Hourly firm 0 0 -$3 Wind integration 0 +$10 (assumed) 0 DA/NU +$2 +$2 +$2 ABP before losses $70.4 $76.8 $79.0 Losses +$7.8 +$4.0 +$13.9 ABP $78.2/MWh $80.8/MWh $92.9/MWh 1. Assumes nominal discount rate of 6.9%, inflation rate of 2.1%, base year of January

51 Portfolio Assembly Once all the Adjusted Bid Prices have been calculated, the evaluation moves to the portfolio assembly phase Assemble combinations of Tenders into portfolios, satisfying: Volume target for firm energy, e.g., 5000 GWh/yr System freshet limitation on total energy, e.g., freshet volume not to exceed X% of annual volume Why do we need a limitation on freshet energy? 51

52 Portfolio Assembly BC Hydro has limited ability to absorb non-discretionary energy during the freshet Two potential impacts at the system level: Displacement of cheap import energy (if load exceeds min-generation), or Surplus energy exported at any price (if min-generation exceeds load) One approach is to link the system freshet limitation to the load growth profile, which essentially maintains the status-quo This would correspond to a 23% limitation 52

53 Portfolio Assembly 7,000 Average Year BC Hydro Supply and Demand ,000 BC Hydro Load GWh/month 5,000 4,000 3,000 2,000 Supply from Non Discretionary BCH Hydro Generation Gap to be filled with BC Hydro Discretionary Generation and 1,000 Supply from IPPs and Resource Smart 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

54 Portfolio Assembly A blended Adjusted Bid Price is calculated for each portfolio that satisfies the portfolio targets BC Hydro may provide a limited number of portfolios to BCTC for further study the blended Adjusted Bid Prices are re-computed for these portfolios, as necessary 54

55 Selection of Optimal Portfolio Selection of optimal cost-effective portfolio based on the blended Adjusted Bid Prices, and non-price factors, including results from the risk assessment 55

56 Non-price Factors Why do we have non-price factors? Intent is to have the ability to incorporate into the selection process certain factors not captured in the quantitative evaluation Allows BC Hydro to make a fully informed decision on the selection of the optimal portfolio having regard to all the facts from all the Tenders at the time of the evaluation Selection of optimal portfolio still based on preference for low cost power Any application of non-price factors will be disclosed in Section 71 filing 56

57 Non-price Factors Some examples of non-price factors include the following: Risk assessment Project development certainty Energy delivery certainty Approved variations not accounted for in the bid price adjustments BC Hydro load resource balance at time of evaluation System impacts at the portfolio level not accounted for in the bid price adjustments Generation technology diversity Regional diversity 57

58 Clean Power / F2006 Call Comparison Terms Clean Power Call F2006 Open Call GHG Green Attributes Hourly Firm Energy No GHG bid price adjuster, any GHG offset risk remains with IPP No bid price adjuster for Green Attributes Bid price adjusted if IPP elects hourly firm energy Magnitude of adjuster depends on profile of monthly HLH firm energy Bidders allowed to pass GHG offset risk to BC Hydro, with a corresponding bid price adjuster If Green Attributes passed to BC Hydro, then Bidder receives a $3/MWh bid price adjuster Bid price adjusted by $3/MWh if Bidder elects hourly firm energy $3/MWh adjuster did not depend on profile of monthly HLH firm energy 58

59 Clean Power / F2006 Call Comparison Terms Clean Power Call F2006 Open Call Wind Integration Adjustment Clean target at portfolio level Freshet limitation at portfolio level DA costs Wind Integration adjustment, to be determined by BC Hydro No target necessary, as all projects must be clean to be eligible Limitation on volume of freshet total energy at portfolio level BC Hydro pays for DA costs No Wind Integration adjustment 50% clean target at portfolio level No limitation on volume of freshet energy at portfolio level IPP pays for DA costs 59

61 EPA Term Sheet Energy pricing for firm and non-firm energy deliveries Time of delivery factors Allocation of firm and non-firm energy for seasonal firm energy projects Calculation of liquidated damages Adjustments to tendered firm energy Other EPA terms Comparison of the Clean Power Call and F2006 Call for Large Projects 61

62 Firm Energy Pricing Firm Energy Pricing Seller to bid in firm energy price (Jan 1, 2008 dollars) Price Escalation Pre-COD: 0% to 200% of bid price to be escalated by CPI Post-COD: 0% to 100% of bid price to be escalated by CPI 62

63 Firm Energy Pricing Firm Energy Pricing (cont d.) Time of Delivery Adjustment Escalated bid price is adjusted by the time of delivery factors (2 x 12 table) Variations in the time of delivery factors during the HLH are more accentuated in the CPC when compared to those of the F2006 Call Potential Option for Time of Delivery Adjustment BC Hydro is considering a 3 x 12 table to reflect the value of energy during the super-peak hours, i.e., 4:00 p.m. to 8:00 p.m. 63

64 Time of Delivery Adjustment for Value of Energy CPC Time of Delivery Factors Time of Delivery Table for CPC 140% 130% 120% 110% 100% 90% 80% 70% 60% 50% HLH LLH Jan 125% 106% Feb 126% 110% Mar 114% 106% Apr 103% 95% May 92% 76% Jun 90% 72% Jul 91% 72% Aug 95% 81% Sep 96% 88% 40% Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Oct 108% 97% Nov 109% 102% HLH LLH Dec 122% 102% 64

65 Time of Delivery with Potential Super Peak Adjustments Time of Delivery with Super Peak pricing Time of Delivery Table with Super Peak Pricing 160% 140% 120% 100% 80% 60% SP HLH LLH Jan 137% 123% 106% Feb 134% 123% 110% Mar 125% 113% 106% Apr 106% 102% 95% May 97% 90% 76% Jun 93% 88% 72% Jul 95% 89% 72% Aug 96% 94% 81% Sep 99% 95% 88% 40% Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Super Peak HLH LLH Oct 111% 107% 97% Nov 114% 108% 102% Dec 131% 117% 102% 65

66 Non-Firm Energy Pricing Non-Firm Energy Pricing Option A: Fixed Price Non-Firm Fixed Price is dependent on COD and contract term Annual Escalation of price at CPI commencing January 1, 2008 Expected price range is $50/MWh to $80/MWh (Jan 1, 2008) Escalated price is adjusted by time of delivery factors Further adjustment for transmission losses from the Point of Interconnection (POI) to Lower Mainland 66

67 Non-Firm Energy Pricing Non-Firm Energy Pricing (cont d.) Option B: Floating Price Monthly non-firm Mid-C Price less wheeling charges and transmission losses back to the BC border Further adjustment for transmission losses from the POI to Lower Mainland Seller to elect 0%, 50% or 100% of non-firm energy priced according to Option A Percentage applied to Option B is the difference between 100% and the percentage applied to Option A 67

68 Allocation of Firm and Non-Firm Energy for Seasonal Firm Projects (Monthly Payments) The following approach will be used to calculate initial monthly payments for the seasonal firm projects: Monthly firm energy is the lesser of actual energy delivered during the month and 1/3 of contractual seasonal firm energy volume When actual energy delivered is greater than 1/3 of the contractual seasonal firm energy, energy paid at the firm energy price will be 1/3 of the contractual seasonal firm energy volume with remainder being paid at the non-firm energy price When actual energy delivered is less than 1/3 of the contractual seasonal firm energy, all energy will be paid at the firm energy price Energy delivered during the HLH (and LLH) will be divided into firm and non-firm on a pro-rata basis using the firm and non-firm volumes established for the month At the end of a season, the sum of the initial monthly payments will be trued-up to the seasonal payment which will be based on the actual firm and non-firm volumes for the season 68

69 Seasonal Firm Energy Delivery Shortfall Liquidated Damages Liquidated Damages (LDs) are incurred for delivery shortfall of contractual firm energy by a season or hour LD amount is $25/MWh, escalated annual at CPI from Jan 1, 2008 Payment for LDs = escalated LD amount x seasonal time of delivery adjustment factor x seasonal firm energy delivery shortfall Seasonal time of delivery factor is the time-weighted average of the time of delivery factors applicable to the season Annual LD limit = 2 x performance security amount 69

70 Seasonal Firm Energy Delivery Shortfall Liquidated Damages Example: Calculate LD payment for actual energy delivery of 95 GWh during the Fall Season of 2011 Parameters: Seasonal Contractual Firm Energy = 100 GWh Seasonal Time of Delivery Factor = 95% LD amount = $25/MWh (Jan 1, 2008) Escalation Rate = 2% per annum Calculations: Escalated LD amount = $25/MWh x (1.02)^3 = $26.5/MWh Seasonal firm energy delivery shortfall = 100 GWh 95 GWh = 5 GWh LD payment = $26.5/MWh x 95% x 5 GWh x 1000 MWh/GWh = $125,875 70

71 Adjustment of Tendered Firm Energy Seasonal Firm Projects Commencing year 4 following COD, the seasonal firm energy volume used for invoicing purposes will be the seasonal tender firm energy volume less the average firm energy delivery shortfall for that season in each of the previous 3 years Forced outages caused by mechanical breakdown will be backed out of the delivery shortfall calculation 71

72 Adjustment of Tendered Firm Energy Hourly Firm Projects Commencing year 3 after COD, the hourly firm energy volume used for invoicing purposes will be the hourly tendered firm energy less the average hourly firm energy delivery shortfall in the corresponding month in the previous year Average HLH firm energy delivery shortfall is calculated by adding the energy shortfalls in the non-exempt HLH in a month and dividing this value by the number of non-exempt HLH in the same month Non-exempt hours are those hours where LDs are payable for energy shortfalls, but exclude those hours when forced outages are in effect due to a mechanical breakdown 72

73 Other EPA Terms Commercial Operation Date Seller or BC Hydro may adjust guaranteed COD based on results of detailed interconnection studies Additional time for Seller to achieve COD where Seller has completed construction of 80% of Seller s plant at time of BC Hydro s right to terminate for late COD COD Operating Test Seasonal firm projects 72 continuous hours at the greater of 90% of the applicable seasonal firm energy delivery rate, and 20% of plant capacity Hourly firm projects 72 continuous hours at 90% of plant capacity 73

74 Other EPA Terms Commercial Operation Date (cont d.) Staged COD Intended for projects with multiple generators BC Hydro will pay for energy associated with the completion of each phase First phase must be capable of generating at a minimum of 20% of plant capacity Maximum of 4 subsequent phases would be allowed after the completion of the first phase 74

75 Other EPA Terms Environmental Attributes Mandatory transfer of environmental attributes EcoLogo certification is not required Freshet Energy At a project level, total energy delivered during freshet period can not exceed volume of total energy tendered during freshet Firm Energy/Plant Capacity Adjustments One-time right to adjust plant capacity prior to COD by the greater of 5 MW and 10%, but not to exceed 10 MW in any case One-time right to adjust firm energy amount by 5% prior to the first anniversary of COD 75

76 Other EPA Terms Performance Security Amount of performance security to be $3/MWh x annual firm energy at the time of EPA signing Amount increases to $6/MWh x annual firm energy within 15 days after Seller s right to terminate for failure to obtain material permits expires Performance security amount increases every 5 years by CPI Separate interconnection security with amount based on estimated costs set out in the preliminary interconnection study Turn-Down Right BC Hydro has right to require Seller to cease generating if Seller exceeds total energy tendered for the freshet period BC Hydro to have discretionary turn-down right subject to payment of full energy price to Seller less avoidable costs 76

77 Other EPA Terms Wind Energy Projects BC Hydro to have right to specify data collection system requirements Seller to provide real-time data access to meteorological data from the collection system Incremental costs for the system to be borne by BC Hydro Renewal/Buyout Rights BC Hydro to have right to acquire project site, permits and related assets on the expiry or earlier termination of the EPA 77
