The purpose of this project is to create a conceptual feasibility study for potential tidal
sites near Homer, Alaska. The project will consist of 2 phases; 1. Resource Assessment
Phase and 2. Feasibility Study phase. Similar studies have been conducted by re vision
consulting for the Electric Power Research Institute (see list of references). For each site,
a conceptual design for a pilot/demonstration and a commercial plant will be established.
The pilot plant will consist of a single device deployed at the site and the commercial-
scale plant will be limited by: 1. extracting < 15% of the hydrokinetic power at the
transect of interest and 2. siting constraints such as water depth and deployment site
dimensions. The following tasks will be accomplished as part of this study.
Task 1: Kickoff Meeting / Site Assessment
A kickoff meeting in Alaska with visits to the deployment sites of interest will provide a
good understanding of the site characteristics, existing infrastructure and parties involved.
Also, during the kickoff meeting a detailed measurement plan will be defined to ensure
that site velocity measurements are carried out in a way that is consistent with
methodologies developed for the assessment of tidal sites.
Task 2: Assistance with Data Analysis
Re vision will assist NOAA to develop a comprehensive velocity data set that can be
used to evaluate device performance during Task 4. Stationary measurement data (at
least 28 days long) will be post-processed to derive tidal forcing constituents at the
deployment site. These tidal forcing constituents will then be used to generate long-term
time series of tidal velocities (18.5 years), based on which statistical data sets can be
generated suitable for the assessment of device performance at the site. In addition, the
total hydrokinetic energy contained within the transect and average power density and
vertical velocity shear will be evaluate to characterize the site potential. A short report
will be issued detailing the site resources and relevant infrastructure components.
Task 3: Device Selection
Based on a preliminary assessment of the site conditions and a list of available
technology options, the stakeholders will select a single device technology which will be
used to carry out the conceptual level design, performance, cost and economic analysis.
Devices that are in an advanced stage of development and for which parametric models
are already established will be favored over less mature devices. Re vision consulting,
LLC will provide a short-list of potential device options to choose from. By selecting
mature device technologies, technology-specific uncertainties can be reduced to a
minimum.
Task 4: Conceptual Level Feasibility Study
A conceptual-level feasibility study will be conducted, which includes; 1. Conceptual
design, 2. Device Performance, 3. Cost Assessment and 4. Economic analysis using a
Municipal Utility economic modeling framework which will be calibrated using the
utilities economic assumptions. For examples of the extent of similar feasibility studies,
sample reports can be downloaded from EPRI’s ocean energy website at
www.epri.com/oceanenergy. A final report will be issued summarizing the findings. The
conceptual feasibility study will be conducted in accordance with methodologies
developed by EPRI detailed in the following reports downloadable from www.epri.com;
TP-001-NA Rev 3 Guidelines for Preliminary Estimation of Power Production, TP-002-
NA Rev 2 Economic Assessment Methodology, and TP-005-NA Methodology for
Conceptual Level Design of TISEC devices. Re vision has developed parametric vendor-
specific device models for a total of 4 different Tidal Power Conversion devices. These
parametric models have been reviewed by independent experts and the device developers
themselves to make sure they are accurately reflecting the device technology. These
models will form the baseline for developing and finetuning models that allow us to scale
the technology of interest to the target deployment site, and incorporate region specific
elements such as available infrastructure components, workboats, weather windows and
supply-chain cost.
Integrated modeling is an approach that allows a rapid evaluation of different generation
options and design alternatives. The basic concept is that changing one design aspect
will have a ripple effect in terms of both cost and design to other components within the
overall system. The following displays the elements of such an integrated model.
Re vision has established integrated models for a wide range of emerging technology
options in River In-Stream, Tidal and wave energy conversion for a wide range of clients,
including EPRI, Chevron, California Energy Commission and Chevron.
Deliverables
A site assessment report will be issued characterizing the relevant site characteristics.
Such characteristics will include grid infrastructure, available tidal resources at each one
of the sites and port infrastructure which could be used for deployment and operational
purposes of a future tidal installation. A second report will be issued detailing the results
of the outcomes of the conceptual design, performance, cost and economic assessment.
