REM Prepared 10/08/96 . 1 TOWN OF ESTES PARK Office Memorandum To: Light and Power Committee From: Richard E. Matzke 7252Â» Date: October 9, 1996 Re: Fall River Hydro Plant Feasibility Study Update Attached is the updated feasibility study for the Fall River Hydro Plant prepared by Eric Jacobson. The original study was completed in August of 1992 and has been updated to reflect current Platte River wholesale electric rates and revised restoration costs. An analysis of production loss ifincreased minimum stream flows were imposed was also performed. The study estimates the value of annual production as follows: Stream Flow Operating Conditions Annual Production ($) No minimum 95,069.30 RMNP Agreement 74,514.96 (4 CFS Minimum) DOW Suggestion 65,042.16 (9 CFS Minimum) The study estimates annual operating costs to be $52,000 and total restoration cost to be $148,000. The study recommends beginning repairs this winter and having the smaller unit (200 kW) operational by spring of 1997. Repairs would continue throughout 1997 on the larger unit (660 kW) with anticipated operation of both units during summer of 1998. The Light and Power Department has requested $100,000 in the 1997 budget to begin the restoration process. The Light and Power Department recommends that we proceed with the proposed schedule and prepare contracts with Steve Chidester to perform the restoration work and with Eric Jacobson to perform consulting services during the project. The contracts would be presented to the Light and Power Committee for recommendation to the Town Board. The issue of minimum stream flow would not need to be addressed until the second unit is ready to be placed in service in spring of 1998 and we have a full season of operating experience with the smaller unit. REM 1-1 TOWN OF ESTES PARK FALL RIVER HYDROELECTRIC FACILITY October, 1996 Eric R. Jacobson 1-2 - A_I=ation The Fall River or Stanley hydro power station is situated on the Fall River approximately 3 miles northwest ofthc Town of Estes Park The plant tailrace elevation is approximately 8072 feet, while the intake at Cascade Lake is at 8472 feet, producing a gross head of400 feet. Cascade Lake is connected to the powerhouse via about 5300 feet of welded steel 30 inch pipe. This conduit also provides raw water to the Town's Fatl River Water Treatment Plant which shares the hydro station site. Other Town owned facilities in the immediate vicinity include an attractive bungalow of about 900 square feet, a bunkhouse ofabout 600 square feet, and the tripartite powerhouse ofabout 2200 square feet. The Cascade Lake diversion structure is situated near a group of privately owned summer cabins which are within the recognized boundary of Rocky Mountain National Park, Cascade Lake and the pipeline feeding the powerhouse and treatment plant were exempted from the deed which transferred the surrounding property to RMNP and are thus not jurisdictional to the National Park Service. B-Hilauy The cemer section of the powerhouse was constructed in 1907 by Mr. F O. Stanley to provide electricity to the Stanley Hotel. His hotel is situated on a bluff about one half of a mile east of the Town of Estes Park- The hotel is thought to be the first all electric hotel in the world. The hotel kitchen was considered an innovative marvel when it was built in that electric appliances were absolutely unheard of. Mr. Stanley felt that smoke from a more traditional coal fueled kitchen might affect his tuberculosis while being offensive to his wealthy clientele. Several years later Stanley constructed the much smaller Stanley Manor on the hotel grounds, a structure which was built for year-round occupancy. Since low winter flows reduced the power generating capabilities ofthe original impulse turbine at the Fall River powerhouse, a single cylinder oil engine was installed in a room adjoining the original generating plant. These two units also provided power to the growing Town ofEstes Park. By 1919 the combined summer load of the Town and the hotel were greatly in excess of the limited generating capabilities ofthese two units. A second (and much larger) water turbine was installed in another addition to the north ofthe original building. This unit was truly "bigger than the stream" and could only produce power from May through September, but since the Stanley Hotel and thus the Town were still principally occupied only during the summer, it was an effective short term solution to the power shortage Within a few years, however, fall and winter loads over taxed the impulse turbine and the small oil engine. A six cylinder diesel engine (Unit #4) was thus installed in a long addition to the south of the original unit. All of these machines, with the exception of the last installed diesel engine, are still in the powerplant complex. together with the original slate and marble switchboards and brass instruments. L1 1-3 SOO *d WOME Sometime during the depression the power system was separated from the hotel and sold to the Public Service Company ofColorado. PSCO ran the system until it was acquired by the Town asa municipal power facility shortly after World War Two. PSCO had removed the big diesel generator after Estes Park was electrically connected to the regional electrical grid. The other three units remained in service umil the 1982 Lawn Lake flood, caused by the bursting of an upstream irrigation reservoir. In the ensuing flood, the log crib Cascade diversion dam was completely washed out, while the pipeline and the powerhouse sustained significant damage. The Town replaced the dam with a smaller concrete structure and the pipeline was repaired This was suflicient to return the water treatment plant to service, but the powerplant Was shovelled out and boarded up: it has not operated since the flood. The plant is doubtlessly eligible for listing on the National Register ofHistoric Places as it is associated with the already listed Stanley Hotel and because of it'; close association with F.O. Stanley (the inventor of much of the Kodak Elm process as well as the Stanley steam automobile).Because of the municipal ownership of the powerplant, the facility should easily qualifj, for grants from the Colorado State Historical Society which administers a considerable fund earmarked for historic preservation. These funds arc generated by taxation on the legal gaming industry in sdect old mining towns. Some tax credits are available to private investors who might undertake the restoration process, but experience has shown that the minutiae of absolute compliance and perfect documentation ofthe restoration costs far more than any savings produced by the somewhat ephemeral tax credits. The plant is of historical interest not only because of it's associations, but also for the pnstine original power generating, regulating and switching technology it contains. I have been in literally hundreds of old powerhouses the world over and have never seen one which compares to the Fall River plant for original technology and functional preservation C.Machineg The powerplant now contains two water turbines and onc oil engine. The oldest water turbine (Unit #1) is a HUG impulse wheel which is directly connected to a 200 kilowatt horizontal shaft WESTERN ELECTRIC generator with an allied belt drive exciter and governor. The newer waterwheel (Unit #3) is a 27 inch Francis type turbine of WORTHINGTON manufacture directly connected to a horizontal shaft, 680 kilowatt, GENERAL ELECTRIC generator with a directly coupled excitation unit and abelt drive governor. Regulation of the first unit is by means of a motor operated spear valve, while the latter unit is controlled by a hydraulically operated wicket gate arrangement. The oil engine (Unit #2) is a single vertical cylinder FAIRBANKS MORSE reciprocating machine driving a directly connected horizontal shaft FAIRBANKS MORSE generator rated at 25 kilowatts. 5 - 1-4 900'd WOMA A very old marble/slate switchboard controls the generating units. Electrical control and regulation is done manually, which necessitated full time attendance. Modern electrical relays can be added to an outdoor line breaker giving the plant the benefits of protective relays while preserving the working historical character ofthe original controls. This would also eliminate the need for full time attendance. 2400 volt power would come off the generator leads. pass through the original indoor breakers for synchronizing. go to the outdoor transfbrmers where the voltage would be raised to the local distribution voltage of 12470 volts, then pass through a modern transmission line breaker which would contain a full panoply of protective relays for the bendt ofboth the distribution system as well as the historic generating units. The water wheel generators have been dried out and megger tested The General Electric generator is in fine condition and could be operated as is. The Western Electric generator has two faulted stator coils but otherwise is intact electrically. Both cxcitcrs fhiled the megger test and no amount ofdrying altered the results. These are small units and are not nearly so costly to rebuild as the main alternating current generators. The Faittanks Morse generator was not tested. Both turbines were opened and inspected. They seem to be operable as is. Water, silt and debris have entered the oil galleries in the bearing stanchions on al] three units. City crews drained the water out of the bearings shortly after the flood, thus preventing appreciable damage to the shafts. The bearings themselves need to be removed and measured, but there does not seem to be an air-gap problem which is ordinarily an indicator of a need to repour a machines babbitt bearings. The motor drive spear valve on the Hug turbine is easily repaired whereas the hydraulic governor and wicket gate control on the Worthington machine, while repairable, will entail more difficulty due to dirt; water and rust problems. The taitrace for the Hug unit is in useable condition. The draft tube assembly for the Worthington unit is entirely missing. The building housing the Hug unit is in usable condition whereas the building over the 1Worthington unit will need to be entircly rebuilt. The powerhouse was heavily damaged on the upstream side; a temporary wall endoses the damaged sections of the building and helps keep both weather and vandals from the machinery. The south building extension (which once housed the big diesel engine) has suffered badly by having ponions of it's concrete foundations undercut by the flood waters. Cables help stabilize the unsupported concrete. Vandals recently broke virtually every pane in the whole complex, thus necessitating not only glass replacement, but sash replacement as well. D.Bgonits The whole development predates both the National Park and the Federal Power Act. It is fortunate that the Town was patient and followed a go slow approach towards permitting 6> 1-5 100 'd WOMA 0-71866 1 I 1-21~~*~i MONTHLY FLOWS ON FALL RIVER, IN ACRE-FEET AT- 67. G:AdaNK fa274.

This resulted in the whole installation being declared non-jurisdictional to the Federal Energy Regulatory Commission. The diversion structure was rebuilt under a Corps of Engineers 404 permit (which probably was not necessary had the Town used Nationwide Permit #2 which anows repairs to existing facilities). As part ofthe comment process under the 404 permit procedure. RMNP got the town to agree to a minimum stream flow in the Fall River below Cascade of 4 cfs from 1 April through 30 September and is limited to taking only 1.5 ch from the river for the rest ofthe year. This means that the plant can only run legally for six months per year. The draft tube for the Worthington unit should likewise be slowly repaired, and can bc donc so without riverine excavations. If a 404 were to be applied for, it is certain that the NPS would attempt to use the comment process as a mechanism to improve their previous gains and demand significant increases in the minimum stream Bow The Town should recall that a recent water sale in Breckenridge was for $20,000 per acre foot and that every second foot lost is equal to 724 acre fect of water per year. At the Breckenridge rate, each second foot of water is worth about $14 5 million: The town has thus already given in excess of $20 million worth of water to the stream via the 1987 RMNP agreement. In sum: Ifcarefilily done, I do not believe thai any additional permits are required. E.-Hydraulics A stream gaumng station was established in 1945 at a point about 2 miles below the plant. This station was in operation until 1953. After 1953, flows in the Fall River have been calculated as being a ratio of flows in the Big Thompson River. For the purposes ofcalculating the water available for power generation. the last 20 years of synthetic data (courtesy of a study done for the Town by a water supply consultant) for the Fall River (Table 1) were averaged (after ddeting the two highest years as being non- representative). to this, via a 3x weighted average, (becausc 1 am more comfortable with rcal Bow numbers as opposed to Â°synthetic* numbers, although the effect of the old Lawn Lake taking water during the high flow months and releasing water later in the summer makes the old numbers different than present day numbers and may make my estimated flows seem slightly better than they actually are) were entered the actual flow data from 1948 to 1953. This number was then reduced by 5% to account for high readings due to ice and debris. A further reduction ofO.829 was made because the Cascade diversion structure has a 34 square mile drainage area as opposed to 41 square miles at the stream gauging station (Table 2). E-Quiuui Ifwe assume that there will be a 10% hydraulic friction loss in the pipeline at all times (in actuality there is very little friction loss during low output times when the water velocity in 9 1-8 100'd WOHA the pipe is less than 2 feet per second), the dynamic head at the plant will be 360 feet. With each cubic fbot ofwater weighing 62.4 pounds, there will be 360 x 62 4 = 22464 foot-pounds of power produced by each cubic foot of water. one cubic foot per second equals 22464 foot pounds per second, or 40.8 horsepower. Since one horsepower is equal to 746 watts, the gross output per second foot of water would be 30.47 kilowatts. Since these machines arÂ¢ sturdy, allhdugh not terribly emcient, the combined hydraulic/electrical efficiency is calculated to be about 75%. It thus follows that each cubic foot of water will produce 22.85 kilowatts If we take the average monthly flows as arrived at in the HYDRAULICS paragraph above and multiply them by 22.851dlowatts, we will get kilowatt hours per month outputs for the plant. Since low flows and prior agreements effectively limit plant operations to the 1 April to 30 September time period, virtually all waters (except those diverted for the treatment plant) remain in the river from 30 September to 1 April. The 1.5 efs that the Town could divert for power purposes in the low flow months would produce only 34.3 kilowatts (about 25000 kilowatt hours per month), certainly not worth the bother of keeping the plant in operation over the winter (but it might be worthwhile as a water rights preservation mechanism). The full 880 kilowatt output ofthe plant divided by 22.85 kilowatts per second foot results in a maximum power diversion of 38.5 cfs. In Table 3 the annual power outputs are considered with no minimum streamflows, with the existing RMNP minimum streamflows. and with the minimum streamflows raised to 4 efs in the winter and 9 cfs in the summer Table 3a (No Minimum Streamflow) Month Average Streandow Mnimum Average Average at Cascade StreamBow Output Production Jan 2.8 ofs 0 cfs 64 kw 47616 kwh Fcb 2.8 0 64 42995 MEr 3.2 0 73 54401 Apr 8.2 0 187 134640 May 36.1 0 825 613800 Jun 134.2 95.7 880 633600 Jul 70.6 32.1 880 654720 Aug 31.2 0 713 530472 Sep 14.0 0 320 230400 Oct 7.9 0 180 133920 Nov 5.3 0 121 87120 Dec 3.6 0 82 61008 TOTAL 3224692 kwh/year 10 Zoo 'd 1-9 1%'033 Table )b (RMNP Agreement Minimum Streamllow) Month Average Streamflow Minimum Average Average Monthly at Cascade Streamflow Output Production Jan 2.8 cfs 2.8 ofs 0 0 Feb 2.8 2.8 0 0 Mar 32 3.2 0 0 Apr 82 4.0 96 69)20 May 36.1 4.0 733 545352 Jun 134.2 95.7 880 633600 Jul 70.6 32.1 880 654720 Aug 31.2 4.0 621 462024 Sep 14.0 4.0 228 164!60 Oct 7.9 7.9 0 0 Nov 5.3 5.3 0 0 Dec 3.6 36 0 0 TOTAL 2528976 kwh/year Table k (RMNP agreement with assurance of4 cfs winter and 9 ofs summer minimum streamflow, as suggested by the Colorado Division of Wildlife) Month Average Streamflow Minimum Average Average Monthly at Cascade Streamflow output Production Ian 2.8 efs 2.8 (G 0 0 2.8 2.8 0 0 Mar 3.2 3.2 0 0 Apr 8.2 8.2 0 0 May 36 1 9.0 619 460536 Iun 134.2 95.7 880 633600 Jul 70.6 32.1 880 654720 Aug 31.2 90 507 377208 Sep 14.0 9.0 114 82080 Oct 7.9 4.0 0 0 Nov 5.3 5.3 0 0 Dec 3.6 3.6 0 0 TOTAL 2208144 kwh/year 11 - 1-10 EDO .d WOMA G.20si-Rcxemigs It is assumed that the Estes Park municipal utility Will pay themselves whatever they save in Platte River Power Authority charges. and give no benefit to [hc plant for power factor corrections, maintaining voltage. preserving highly valuable water rights, or by keeping dollars in Estes Park which otherwise would be fent out of town to Platte River. This rate is 1.5 cents per kilowatt-hour (energy) and $10 64 per kilowatt-month ( 15 minute on peak demand). Since the system peak demand and the powerhousc peak output probably wit} not be coincident, and <ince there ix not enough storage in Cascade to make the peaks coincident, the revenue, are derived by using average monthly outputs multiplied by the demand rate. This probably is only fair as this is exactly what the Town might expect for a real world Platic River peak demand reduction (Table 4).

When this is divided by 43560 cubic feet per acre foot, we find that Estes Park has presently given away 365 acre feet of senior water per year. At $20,000 per acre foot, this is worth $7,300,000. The additional water requested under the 4/9 modification would reduce the plant output by another 320,832 kilowatt hours per year. This places an additional 7.33 million cubic feet of water in the bypass section of the Fall River per year, resulting in a 168 acre foot decrease in the value of the municipal water right. At $20,000 per acrc foot, this secondary decrease is worth approximately $3,360,000. Table 5 covers the estimated cost of returning the plant to service. Unit #l is returned to service first because the spear valve assembly can be repaired more quickly than the hydraulic mechanism on Unit #3, because # 1 is in a good building whereas the #3 unit needs a reconstructed building, and because the tailrace for the #1 unit is in usable condition, whereas the #3 unit will necd a new draft tube assembly. /4 1-13 NOMA Table 5 (Restoration Cost Estimates) Building shell repairs $ 20000 Foundation repairs 3000 Riprap and embankment 1000 Generator # 1 repairs 3000 Exciter #1 repairs 1000 Generator #2 repairs 1000 Exciter #2 repairs 1000 Shaft and bearing clean up 2000 Relay and panel check out 6000 Relay testing 1000 Miscellaneous concrete work 3000 Freight and trucking 3000 Lightning arrestors 0 Cables and grounding 2000 Entry door 1000 Tools 2000 Premesis wiring 2000 Generator and station wiring 6000 Relays, overcurrent for individual machines 0 Transmission line breaker 0 Relays for transmission line breaker 3000 Tank and float valve for treatment plant 4000 Transformers 0 Switching rack and disconnects O Reconnect pipe 2000 Repair penstock 1000 Repair house 5000 Paint all buildings (exterior) 4000 Replace broken sash and glass 6000 4000 Plumbing repairs Roofrepairs 4000 Appliances 1000 Archacologist 4000 52000 Contingency TOTAL $ 148.000 15 1-14 f00'd WOMA 1.

He is a great carpenter and really helpful on the machinery repairs as well. 1 would be glad to come over once a month (when I am in Boulder for Cogen Technology board meetings anyhow) I suppose that I would have to spend about six weeks in Estes Park in late winter to get # 1 started this spring, then plan on spending another six weeks there in the spring of 1998. I am poitive that we could have # 1 operating by April, provided we did not have to do any repairs on the penstock beyond the one known leak under the horse trail. I.-Canglusion The plant should make a small prolit beyond making it's own principal and interest payments. lf a grant were found. the P and I fund could be reduced and a penstock replacement fund started. The principal value ofthc plant would be to maintain beneficial use of the Town's water rights until such a time as they were needed. If the amount of water being protected is. say, 20 ds for half a year, that is approximately 7000 acre feet of water, worth approximately $ 140 million. Because ofthe treatment plant, this is a consumptive right, thus it is probably the Town's most valucable asset. Even if the hydro plant were to lose money, I believe that it would be very unwise not to repair it. The water lights are simply too valueable to risk any sort of abandonment. Best Regards Eric R Jacobson October 3, 1996 16 1-15 SOO 'd WO Md Stephen Chidestor Box 1349 Telluride CO 31435 To: The Town of Estes Park To whom it may concern Evic Jacobson of the Brid.11 Veil Falls Hydropower station , has told me of your intencions to ,Â·ennovate the Estes Park Hydropower station. Lhat you may be interested in a similar result as we:ve accomplished here at BVFHPS: and furzher, that you may be interested in hiring me as a carpenter to work on elvis project. After giving it some thought , my wife Anikke and I have decided that we are interested in this project as well. We visited the hydropower site casually around September 1,1996, and without going into details, I felt comfortable with Eric Jacobsons quick estimate of about iD months of work for one carpenter (less time if I were to hire some help). Beyond that , we were wondering about 1) the possibility of us living in one of the houses on site,as soon as they could be readied. 2) i offer myself here in the Telluride region for anywhere from $20-30/hr.; a sliding scale. I ask my clienrs to place themsel ves into that scale according to what they believe they can/should pay. If the living arrangements and pay scale are within your expectations, why don'c you lot me know and we can then push forward with a more detailed work plan. I would also expect to pay you a visit; perhaps that would be an appropriate next step. We look forward to your response.

Matzke-727Â»- Date: October 9, 1996 Re: Municipal Lot Primary Underground Trenching Contract Change Order Request The Town Board awarded the contract for installing trench and conduits for the Municipal Building Parking Lot primary underground project to Chiefs Landscaping for a cost not to exceed $7390. The Light and Power Department requested the contractor to install additional trench and conduits to allow rerouting of the primary underground feed to the Municipal Building. This work will greatly reduce the outage time when service is transferred from the overhead line along the north ofthe parking lot to the new underground cable. The new route does not pass under the building as does the existing feed. The cost ofthis additional work is $3,497.20 The original bid did not include concrete flow fill as a back fill material. At the request ofthe project manager to ensure the quality of the parking lot project, flow fill was installed. The additional cost for this change is $11,672.27. There is sufficient funding for underground capital projects in the 1996 budget to cover these costs and the Light and Power Department requests approval of these change requests.
