Slide 7

History of Hydropower Analysis Center Formed in 1948 as Hydropower Evaluation Section Primary Purpose was Performing Hydropower Economic Analysis to Determine Viability of Proposed Hydropower Developments in PNW Expanded to Perform Analysis Throughout U.S. also, Foreign Countries Performed Studies for all Corps Districts and Foreign Countries, for example, China, South Korea, Nigeria and Others Established as a MCX in 1996

Slide 8

ER 1110-1-8158 Designates Hydropower System Analysis MCX Mandates all USACE components to arrange with and utilize MCX administrations. Obliges MSCs to screen and confirm fitting utilization of MCXs

Slide 9

The Hydropower Analysis Center (MCX) Areas of Expertise: Hydroelectric Design Center Support Major Powerplant Rehabilitation Generator Rewind Studies Work for Districts and Other Offices Comprehensive River System Studies Cost Allocation & Water Supply Reallocation Studies Power Values Miscellaneous Studies (Operational, Structural and Equipment Modifications, and so on.)

Slide 10

The Hydropower Analysis Center (MCX) Areas of Expertise: (Continues… ) Special Work Activities Develop Procedures for Evaluating Hydropower Benefits Risk Analysis of Major Components Wrote Hydro Power Engineering Manual PEBCOM FERC Review

Slide 11

Cost Allocation And Water Supply Reallocation Studies: Analysis of the hydropower advantage segment of cost distribution considers for multi-reason water asset ventures. Water stockpiling reallocation studies to recognize control advantages and income predestined with reallocation of capacity for civil and modern water supply withdrawals. Late capacity reallocation thinks about incorporates White River Minimum Flow in SWL , Lake Greeson in MVK and John H. Kerr in SAW.

Slide 12

Presentation Overview I. HAC Function, its Staff, Organization Location and History II. General Overview of Hydropower Benefit Process III. Review of Hydropower Benefit Process Used in Water Supply Studies IV. Specifics on Hydropower Benefit Process Used in Water Supply Reallocation Studies with Illustrative Example V. Wellsprings of Information on Hydropower Benefits and Water Supply Reallocations VI. QUESTIONS

Slide 13

Definition of Common Terms Energy - The ability of doing work, communicated as far as kilowatt-hours (kWh) 1 kWh of vitality would be created by a ten-foot 3D square of water falling 42.5 feet vitality utilized by a normal family unit is 175,000 kWh/year

Slide 14

Definition of Common Terms Capacity - the most extreme measure of force that a producing unit or powerplant can convey under a predetermined arrangement of conditions

Slide 15

Definition of Common Terms Dependable Capacity - A measure of the measure of limit that a venture can dependably contribute towards taking care of framework pinnacle demand.

Slide 16

Definition of Common Terms Unit Power Values Energy Value - speak to the fuel cost or variable cost of an option warm era asset that replaces the lost hydropower era. Measured in units of $/MWh Capacity Value - speaks to the capital cost, altered O&M cost of the dislodged warm asset. Measured in units of $/kW-yr.

Slide 17

Determination of Energy Impacts Formulation of options (with & without capacity reallocation) Simulation of contrasting options to decide framework era for every option utilizing a Sequential Streamflow Routing (SSR) display or recorded information Difference in era between options with and without capacity reallocation is resolved

Slide 18

Determination of Energy Value and Energy Benefits Foregone Simulate the operation of the power framework utilizing a hourly framework creation cost (SPC) demonstrate "with" and "without" hydropower vitality misfortunes. The estimation of misfortune vitality is dictated by subtracting the SPC of the "without" from the "with" option. At that point partitioning the distinction by the vitality misfortune to get the vitality esteem

Slide 19

Determination of Energy Value and Energy Benefits Foregone (proceeds… ) This procedure rehashed for no less than five incremental future years and a unit normal yearly vitality esteem is figured utilizing a present-worth system Energy benefits inferred by duplicating the unit vitality esteem by the distinction in hydropower era between the base and different choices

Slide 20

Determination of Dependable Capacity Impacts Select fitting technique (typically Average Availability) for processing tried and true limit Coordinate with Power Marketing Agency (PMA) to decide the attractive limit doing a basic time of unfavorable conditions. Reenact agent verifiable period with a SSR display, which incorporates a basic water year, to decide extend capacity.

Slide 21

Determination of Dependable Capacity Impacts (proceeds… ) Determine the quantity of hours on crest for every venture by partitioning the normal week by week vitality delivered amid the basic time frame by the PMA\'s attractive limit Determine the genuine supportable limit for every year of the chronicled period for the "with" and "without" options

Slide 22

Determination of Dependable Capacity (proceeds… ) The normal of the real supportable limit for every year in the recorded period is the normal tried and true limit The distinction in normal trustworthy limit between the "with" and "without" option is the pick up or misfortune in tried and true limit brought on by the capacity reallocation

Slide 23

Determination of Capacity Value and Capacity Benefits Foregone The limit esteem speaks to the settled cost connected with the augmentation of option warm influence plant limit that would be uprooted by the hydropower plant HAC registers the limit esteem utilizing a procedure created by the Federal Energy Regulatory Commission (exceptionally detail handle!!) Capacity advantages are figured by increasing the limit esteem by the pick up/misfortune in tried and true limit

Slide 24

Presentation Overview I. HAC Staff, Organization Location, History II. General Overview of Hydropower Benefit Process III. Outline of Hydropower Benefit Process Used in Water Supply Studies IV. Specifics on Hydropower Benefit Process Used in Water Supply Reallocation Studies with Illustrative Example V. Wellsprings of Information on Hydropower Benefits and Water Supply Reallocations VI. QUESTIONS

Slide 25

Typical Participants in Water Supply Power Impact Analysis Power Marketing Agency Marketable Capacity Energy and limit rates for incomes inevitable Division as well as District workplaces Historical hydrologic/era information Water supply withdrawal sums Existing withdrawals Project water control arrange

Slide 26

Typical Participants in Water Supply Study (proceeds… ) Project Personnel Project operational data HAC Benefits Foregone Revenues Foregone Credit to PMA

Slide 27

Sources of Data and Computer Models District Hydrology & Hydraulics office PMA, EIA SSRs: SUPER, HYSSR, HEC-5 SPCs: PROSYM, POWRSYM, AURORA Capacity Value Spreadsheet Model

Slide 28

Cost of Water Supply Reallocation to Hydropower ER1105-2-100 expresses that the cost of water supply reallocation to the client be the most noteworthy of the accompanying: redesigned cost of capacity in the Federal venture (registered by District) control benefits predestined power incomes inescapable substitution cost of force

Slide 29

Power Benefits Foregone Power benefits inescapable are separated into two segments: Lost vitality benefits in view of the misfortune in era at-site, upstream and downstream as an aftereffect of water being occupied for water supply as opposed to going through the units Lost limit benefits in view of the loss of creating head because of lower post-withdrawal store heights lessening in convenience of the limit due
