Below are several things I learn from the two webinars on 11/3.
Webinar ‘Wind+Storage – Transitioning to Dispatchable Production & Management’:
Global energy demand is projected to peak in 2030. Although population grows, electricity efficiency improves.
The sale of electric vehicles is projected to exceed 50% of the market in 2032, which is one of main drivers of storage development such as renewable curtailment.
Storage, interconnection, flexible power plants etc can provide electricity flexibility.
Collocation of renewables with storage in forms of battery or pumped storage is important. For example, electricity generated by Hywind’s 30MW floating wind farm is transported to the onshore substation, which is connected to 1 MW batteries that is connected to the grid. Intelligent software learns to optimize when to store and dispatch wind power generation from multiple data sources ranging from weather forecasts, market prices, and electricity demand as well as grid services. There may be potential to integrate battery storage into turbine towers.
Regulations need to be updated and recognize hybrid resources as fully-integrated systems.
Webinar ‘An Overview of Floating Offshore Wind and the Use of Spatial Data on the West Coast’ (Presenter: Mr. Frank Pendleton):
California’s greenhouse gas legislation. CAISO’s 2013 report: What the duck curve tells us about managing a green grid.
Floating offshore wind projects around the world such as Japan, WindFloat Atlantic in Portugal and so on.
Previous cut-off ocean depth for development is 1100 m, now that 1300 m may be workable.
NOAA DEMS (https://www.ngdc.noaa.gov/mgg/coastal/coastal.html) measures ocean slope in degree at approximately 80 m pixels, which shows pretty flat sea floor in the Morro Bay call area.
The Diablo Canyon call area seems to be largely shaped by cable locations.
PNNL’s Lidar Buoys are planned to be deployed in spring 2020 for one year. Two locations selected under the permitting process by the time of presenting are within or close to the Humboldt and Morro Bay call areas.
AIS data track vessel traffic and can be turned into a density map. AIS can be downloaded here https://marinecadastre.gov/ais/.
Bird data – PaCSEA. Marine mammals – NOAA. Relevant data sets can be found on Data Basin – California Marine & Coastal Ecology and Natural Resources ( https://databasin.org/galleries/e1e3eab6e86446e7905c824474f70428).
