O'Neill II, CPPO, FNIGP Director of Purchasing & Risk Management DATE: ATTEST: City Clerk APPROVED AS TO FORM: Assistant City Attorney [Insert Professional's name] or [Insert Partnership Name] or [Insert individual's name] or Doing business as [insert name of business] By: Title: CORPORATE PRESIDENT OR VICE PRESIDENT Date: ATTEST: Corporate Secretary (Corporate Seal) 16 REQUEST FOR PROPOSAL P1055 Planning Study: Medium Voltage Electric Distribution System Fort Collins Utilities, Electric Planning & Engineering Services Dept (hereafter referred to as 'FCU') requests your written proposal and quotation on the following scope of work for professional services for a planning study to revise a former master plan study for the city's medium voltage electric distribution system. SCOPE of WORK FOR PROFESSIONAL SERVICES In 1984, Fort Collins Utilities (FCU) contracted for professional services to create a long range, or 'master', plan for the projected expansion of the City of Fort Collins (City) out to its then designated urban growth management area (GMA) boundary, and resultant growth of the electric utility's service territory and customer load. That study concluded that the entire service territory could continue to be served in the most economical manner by what are either now presently existing substations, or else future substations at currently identified substation sites. Now that 22 years have passed since that study was completed, as the City has expanded further, as it has continued to develop internally, and as it has approached its restricted urban GMA boundary, the purpose of this planning study will be to reexamine and update many of the assumptions and projections that determined the customer load densities, composition, and foreseeable growth patterns as applied to the northeastern quadrant of the City. This new study will similarly reexamine and update the projected construction costs of distribution feeders and substation sites within this defined quadrant. Consequently, the scope of work for this planning study will not be to revise the entire previous long range plan, or to generate an entirely new long range plan, but rather only to produce an updated long range plan for how best to serve the City's northeastern areas, given some combination of existing and future substation sites. To date, the City has not succeeded in securing the real property for a suitable substation site to be constructed in the future in the far northeastern section of the City, or at least within its GMA boundary but on county land outside the existing city limits. FCU has thus far been unsuccessful in identifying a willing seller in the areas where some of the foreseeably least cost and most favorable sites are located. As a result, in the event the findings of this study confirm FCU's current expectation of the need for at least one additional substation in this area and to the east of 1-25, then FCU will have to initiate a condemnation proceeding to obtain either one of the (2) identified potential sites, or alternatively an as yet unidentified site that would be recommended as a finding of this planning study. FCU will thus be relying upon the findings resulting from comparisons of the many case studies that will be performed within the scope of work for professional services for this planning study to help establish and defend its selection of a suitable substation site during the condemnation proceeding. Principal Obiectives To achieve that goal, an acceptable planning study must either incorporate or account for all of the following objectives, evaluations, and limitations: 1) The principal goal of this planning study is to determine whether or not FCU's existing substation (Richard's Lake) and future distribution substation at the existing transmission substation site (Timberline) will be sufficient to serve all of the eventual load growth in the northeast quadrant of the City out to the currently designated GMA boundary at complete build out. 2) If the projected load growth in the northeast quadrant of the City exceeds the capacity of these (2) substations to serve, this study will determine the optimum locations for a future substation based on economics and feasibility. Although the initial iterative process will require the consultant to evaluate any number of potential sites in its efforts to rank the sites, once the top ranked site is identified as the one most likely to require the least investment to construct and operate, it will then be compared in a more detailed manner against the (2) sites already identified by FCU as potential substation sites to determine the top contender. This iterative process will then be repeated given a change in the customer'load center' due to a foreseeable (yet currently not predicted), expansion of the GMA boundary. 3) Creation of a detailed distribution system model by the consultant using an application such as WindMil or SynerGee is not specifically required for this planning study, although if the consultant elects to build such a model for the purpose of achieving the other mandatory objectives, FCU will require that the model be built in WindMil and be included along with the consultant's other documentation to be transmitted to FCU upon completion of the project. 4) Just as no detailed distribution system model must be delivered to FCU by the consultant as part of the scope of this project, neither is any detailed distribution feeder analysis required. At most, the feeders need only be modeled to the extent necessary to estimate loading limits, maximum distance and allowed voltage drop limit, construction costs, losses, and possibly some estimated operation and maintenance costs. 5) In addition to the 'base case' series of case studies that will evaluate the relative costs and benefits of the various substation sites given the existing GMA boundary, this planning study shall also include a synopsis of how these various substation sites would compare, given an expansion of the service territory to accommodate a limited expansion of the GMA boundary of a few square miles to the north and east of the existing GMA boundary. The key observations to be drawn from this additional analysis of potential additional service territory, and that are to be included in the final report, are those observations that confirm the trend in how the customer 'load center' is expected to shift, how far, and how drastic of an impact there would be upon the relative cost discrepancy between the currently identified new sites and an unknown additional site to serve them. 3 6) Whenever various case studies are compared on a cost basis, the projected costs for transmission line construction must always be tracked and recorded independently of the other costs associated with substation and feeder construction. FCU is not directly responsible for these costs, but they are to be included in the iterative process of comparing sites. 7) When comparing all of the many case study alternatives to be evaluated, the following estimates of probable costs are to be included in those, evaluations, although no attempt is to be made to perform a present worth analysis of these future costs (the dates of construction are too uncertain). a. Substation construction / expansion b. Transmission line construction / expansion c. Distribution feeder construction (750 Al system only) d. Distribution feeder losses (750 Al system only) e. Distribution system operation & maintenance costs Proposed Procedure to Achieve Objectives To achieve this planning study's principal objectives as listed in the prior section, the following procedural goals and process are proposed by FCU for implementation by the consultant, subject to comment and revision after receipt of the consultant's more detailed proposals on how it might comply and / or deviate from this process while still satisfying the principal goals. 1) Develop a land use / infrastructure / load density geospatial model from the street centerline; hydrographic, topographic, and other shapefiles provided by the City for the designated northeastern area of the City in ArcGIS, upon which to evaluate the various case studies for all of the substation sites to be evaluated. 2) Incorporate into the land use / infrastructure / load density model, zoning, and parcel data representations for load density to permit a determination of hypothetical 'load centers' for each substation site to be evaluated. 3) Calculate the 'load center' by combining parcels / zoning areas based upon their individual geometrically constructed 'load centers' to obtain an extrapolated 'load center' for the combined parcel / zoning area set. This series of calculations will then consist of an iterative process, to be performed either manually, or with the aid of some custom programming by the consultant (either means is acceptable), until a few choice 'optimized' solution sets are generated for use in analyzing suitable sites meeting FCU's siting restrictions. 4) Identify potential new substation sites using the following criteria to the extent that each applies to the site under investigation, as it would for the case of the two sites already identified by FCU: a. Find the 'load center' of the parcels / zoning areas for 'ultimate' build out at some unknown point in the future by the procedure described in Steps 1, 2, & 3. b. Assign the load surrounding the substation site to the substation up to its specified capacity (28 MVA per transformer, or 56 MVA total, apportioned among I 14 distribution feeders) in another iterative procedure, until the entire service area of the substation can be defined. During this process, the consultant must account for both proximity of load and the areas parcels / zones / areas served by either existing or planned feeders from the existing and future identified substations. c. Weigh the following parameters in the geospatial model to limit the solution sets: 1. Locations within and/or near the center of the new substation service area identified in the prior step. 2. Relative `balance' of overlap or gaps in coverage provided by the combination of new and existing substation sites relative to the ultimate 'load center.' 3. Proximity of each site to existing and/or planned main feeder trunk routes 4. Assess the potential solution set of sites identified above relative to the parcel sizes in the vicinity of the potential locations, and then contrast them with any restrictive geospatial features (e.g. water features, railroads, cemeteries, natural areas, etc.). d. The probable costs associated with each prospective substation site can be quantified using linear estimates of site acquisition costs (if provided by FCU), feeder costs to connect to existing and/or planned main trunk feeder routes, substation construction costs, transmission construction costs, feeder losses, and feeder operation & maintenance costs (if provided by FCU). e. The remaining solution set of sites will then be ranked according to the results of the probable costs associated with each site when weighed in conjunction with the restrictive geospatial features, until the single 'best' site is chosen. Available Resources and Data 1) Existing distribution system maps in AutoDesk ACAD showing 750 Al feeders. Less detailed feeder maps available in ESRI ArcGIS file formats. 2) Existing and hypothetical GMA boundaries 3) Existing City land use, zoning, and infrastructure plans available in ESRI ArcGIS file formats 4) Copy of original 1984 long range planning study (only final report available) 5) Load density values for projected land use classifications and foreseeable development categories 6) General overview design, construction, and operating standards for substation transformer loading, feeder loading, substation construction, and feeder construction. I 7) Billing data on existing substation transformers and feeders if requested by the consultant. (Not necessarily foreseeably warranted given the assumption that this planning study is evaluating some version of near ultimate build out for the study area, but available nonetheless) Data and Supplied Assumptions 1) Each substation at ultimate build out will consist of (2) 56 MVA ONAN/ONAF/ONAF substation transformers, and (14) feeders consisting of 750 Al cable. Assume transformers can only be loaded up to a maximum of 28 MVA, and each feeder up to 300 A. 2) All 750 Al distribution feeders are installed underground in duct banks. No 1/0 Al laterals need be analyzed or included in the course of this study. 3) The study area to be evaluated within the scope of this project will be served by: a. One existing substation (Richard's Lake) b. One future substation on an existing transmission substation site (Timberline) c. One potential future substation on identified and unidentified sites for the evaluation performed at the current GMA boundary d. One potential future substation on identified and unidentified sites for the evaluation performed for an expanded GMA boundary 4) Cost of construction will be provided for the following: a. New distribution feeders and duct bank b. Substations c. Transmission line extensions and/or expansion 5) FCU is not responsible for any transmission system construction, including 115 kV lines and substation bus and equipment construction. Those costs are to be calculated by and incurred by FCU's transmission provider, (Platte River Power Authority) PRPA. 6) For the (2) identified future substation sites, the major distribution feeder duct bank routes connecting back to the existing distribution system will be supplied to the consultant for use in its cost benefit analysis. For the most part, these routes follow either the major arterial roads or railroads that currently exist. However, some of the duct bank routes that extend out from these sites towards the GMA boundary will fall to the consultant to identify, but only in a general manner to the extent necessary for the consultant to compile a reasonable cost comparison between the cases. 6 FINAL DOCUMENTATION A final report and brief Powerpoint presentation must be prepared and submitted to FCU in a bound paper and electronic format (MS Word and Excel) describing: 1) Data used 2) Operating assumptions made 3) Alternatives investigated 4) Evaluation results 5) Recommendation of the least cost and most reasonable alternative This final report must also summarize the development of the site selection process, and include extensive graphics generated in ArcGIS file formats to convey the quantitative geospatial process used to determine the potential substation sites, substation service areas, and parcel / zoning / infrastructure customer load densities. This report will also include a schedule / tabular summary in Excel format of the probable cost estimates used to determine the site rankings. ArcGIS files, including maps, layers, and supporting shapefiles, shall be provided to FCU upon completion of the report. Maps will include symbol legends and be defined for plotting both at ANSI B, D, and E sizes. At least one full size, and one reduced size map of each principal site choice shall be submitted along with the report and electronic files. SCHEDULE Partial completion of this planning study is required by February 16, to the extent that a reasonable projection can be made with substantial probability as to the necessity of at least one additional substation site to the east of 1-25. However, full completion is requested within (12) twelve weeks of award of the professional services agreement. REVIEW AND ASSESSMENT Professional firms will be evaluated on the following criteria. These criteria will be the basis for review of the written proposals and interview session. Interviews may be conducted at the option of the City of Fort Collins.
