Application #13008 [Chignik Hydroelectric Dam] [City of Chignik] HYDRO AEA REF Review Summary P a g e | 2 Project Description [Section 2.4]: Conceptual & final design 385 kW Run or river hydroelectric project Project Concerns: Q&A Between Evaluator and Applicant [include dates, participants, means, etc.]: Additional Details / Considerations:  ANTHC management.  Current water supply from dam flows through pipe installed 1947 (wood stave) through mid - 1980’s. City water supply pipe is in immediate need of replacement because of deterioration.  City has FERC license.  Decrease in load? Heat in estimate?  No 2019 PCE data.  App diesel has $3.69. PCE 2016-2018 has $2.25-$2.69  Energy divided by gallons saved comes out as 17.7 eff. Using eff of 14 kW/gal saves 80k gal.  Sect 3.1 has Concep design in 2021-2022. Yet3.2.3 has an actual cost of Feasibility & Conceptual design. Amount to be requested is for final design.  2014 Hatch/CE2 Const cost $7.8m which includes $250K geotech. Table 5-2 shows contractor cost of $6.7m and development costs (FERC, Geotech, survey, historic, owner adm) of $1.13m.  2018 ANTHC report gives cost of $7.4m for hydro & drinking water. Drinking water only project would be only $4.9m. Access trail of $390,000 may have been built in 2018 so would account for lower estimate of $7.4m. Report also gives design budget $379,829 for dam, access, water supply pipe, & hydro turbine. Likely $379k does not include geotech/FERC/survey Overall Recommendation (Full, full w/ special provision, partial, partial w/ special provision, not recommended): Partial Justification for any recommendation besides Full: Requested amount seems to be substantially above 2018 ANTHC design cost estimate and above similar final design projects. Special provision recommended: Official Stage 2 Follow-Up / Comments: Application #13008 [Chignik Hydroelectric Dam] [City of Chignik] HYDRO AEA REF Review Summary P a g e | 3 Stage 2 Scoring (Bold = field scored by evaluators) Scoring Criteria Scoring Notes Preliminary Score (0-10) 1) Project Management, Development, and Operation 7 a) The proposed schedule is clear, realistic, and described in adequate detail. [Section 3.1] Start date prior to having State funding. Will have trouble doing all studies shown in the period (prior to 2022 spring) if funds not available until July. City has FERC license. Documents may need to be submitted to FERC and agencies which will cause delays. b) The cost estimates for project development [Section 3.2], operation, maintenance [Section 5.4.6], fuel, and other project items meet industry standards or are otherwise justified. 1) Development: Cost estimate for final design & permitting seems on the high side. $278,000 for PM & contingency. Feasibility Report has funds in cost estimate for working with FERC. Hatch/CE2 had development costs of $1.13m yet ANTHC design cost estimate has $380k. So design costs not clear. 2) Operations: Response to 5.4.6 #1 (non-fuel savings) is given as $234,315. That amount is the fuel savings. 3) 5.4.2.3 shows $55k O&M for existing system. 5.4.6 Option 1 (diesels partially on) gives est annual O&M cost for renewable project as $27,543. Believe this was to be new system (project plus diesel). 6.1 shows O&M savings of $8,848. Unsure where this number came from. 5.4.5 notes first 5 years hydro O&M is est to cost 0.75% of the overall construction cost. With est cost of $6.161m (Feasibility has a higher construction cost). Feasibility Report states the %0.75 is for est monitoring work (fish) so it should be added to hydro O&M estimate. 4) Maintenance: c) The Applicant’s communications plan [Section 3.3], including monitoring and reporting [Section 5.5], is described in adequate detail. 1) Communications plan: Yes 2) Project monitoring & reporting: Yes. Will be filled out more once project Application #13008 [Chignik Hydroelectric Dam] [City of Chignik] HYDRO AEA REF Review Summary P a g e | 4 d) Logistical, business, and financial arrangements for operating and maintaining the project throughout its lifetime and selling energy from the completed project are reasonable and described in adequate detail [Section 7]. 1) Logistical: 2) Business: 3) Financial: Reasonable in that the hydro system should be able to produce more than enough energy for City loads and have excess to sell to processor if price is right. 2) Qualifications and Experience 7 a) The Applicant, partners, and/or contractors have sufficient knowledge and experience to successfully complete [Section 4] and operate the project [Section 7].1 1) Complete project: Management has little experience with hydroelectric projects & FERC. They need experienced contractors. Feasibility Report has a higher cost estimate from 6 years ago. Concerned that design/construction/license cost higher than stated because of inflation & experience. 2) Operate project: City has experience operating a small hydro. With the condition of existing hydro there has not been enough O&M being performed. a) The project team has staffing, time, and other resources to successfully complete [Section 4.1.3] and operate [Section 7] the project. 1) Complete project: Yes 2) Operate project: Yes b) The project team is able to understand and address technical [Section 5.3.1], economic [Section 6.1.3], and environmental barriers [Section 5.3.2] to successful project completion and operation. 1) Complete project: Yes. 2) Operate project: Yes. Aside from declining population reduced rainfall is a risk. a) The project uses local labor and trains a local labor workforce [Section 4.2]. Yes, as available. 3) Technical Feasibility 10 1 If the applicant has not yet chosen a contractor to complete the work, qualifications and experience points will be based on the applicant’s capacity to successfully select contractors and manage complex contracts.
