This dataset comprises high-resolution Finite Volume Community Ocean Model (FVCOM) hydrodynamic model output for the Maine coast developed under a TEAMER RFTS 12 project with the Tide Mill Institute, with technical assistance from PNNL. It was designed to assess community-scale (up to 1 MW) tidal stream resources by simulating a 30-day period in and around the Casco Bay/Mid-Coast region, with the framework enabling future expansion to other coastal sections. The modeling suite includes baseline hydrodynamics and hypothetical turbine array scenarios implemented with PNNL's FVCOM-TEC module using specifications from three commercially deployed or in-development turbines. The dataset characterizes depth-averaged currents and power density across the model domain, kinetic energy flux at transects spanning identified hotspots, and turbine-level annual energy production (AEP) for multiple deployment depths and array configurations. It is intended to support screening and comparison of community-scale tidal hotspots, preliminary siting, and evaluation of potential energy yields and variability for small arrays in Maine's tidal channels.
