Why is OSW so attractive from a power generation standpoint? In short, it promises a renewable, low-impact, effective means of meeting California's growing electrical demands.
The Central Coast is desirable not only for its wind profile, but also because of the existing 500 kilovolt transmission lines, shown as thick red lines in the map below, that currently terminate at the Diablo Canyon Nuclear Power Plant, very close to the Morro Bay Wind Lease area. After the anticipated decommissioning of Diablo, these lines present ready transmission capabilities for an offshore wind farm:
One of the main benefits of OSW is that it exhibits a favorable generation profile that coincides with peak electrical demand in California, represented by the black line in the normalized graphs below. While solar generation (red line, below) peaks mid-day, onshore wind (green line) and offshore wind (blue line) peaks often coincide with peak electrical demand, with offshore wind demonstrating the most favorable generation profile of the three renewables:

It is because of this favorable generation profile and low environmental impact that OSW is such an exciting prospect along California's Coastline. Cal Poly's expertise and facilities offer an ideal combination to facilitate its development on the Central Coast.

Local diurnal wind-driven variability and upwelling in a small coastal embayment: The oceanic response to high-frequency local diurnal wind forcing is examined in a small coastal embayment located along an understudied stretch of the central California coast. We show that local diurnal wind forcing is the dominant control on nearshore temperature variability and circulation patterns.
Seasonal variability of upwelling and downwelling surface current patterns in a small coastal embayment: In this study, we apply a conditional averaging technique to investigate upwelling- and downwelling-driven circulation in a small coastal embayment located in Central California (San Luis Obispo Bay). We also investigate intraseasonal differences in the current patterns.
