We can take another look at the Pacific Gas & Electric (PCG) battery energy storage (ESS) project in Moss Landing, California, thanks to the latest drone video from EKMMetering, which should soon be completed. Once completed, it will be one of the most largest energy battery storage facility in the world.
The design and deployment of 256 Tesla Megapacks seems to be mostly done. The battery systems are still shielded, but a total of 182.5 MW of electricity and 730 MWh of energy capacity can soon be connected to the grid.
In Moss Landing, California, PG&E ESS in brief:
- 182.5 MW and 730 MWh at PG&E’s Moss Landing California electric substation
- 730 MWh is equivalent to 7,300 electric vehicles with batteries of 100 kWh each.
- On 33 concrete slabs, 256 Tesla Megapacks (approximately 3 MWh each)
- Completion and energization are planned for the start of 2021
- In Q2 2021, complete commercial service
This particular initiative is one of the largest in the world, and it will be the largest until it is launched, as far as we know. The pipeline, however, also has larger systems, including 1,200 MWh/300 MW battery energy storage by Vistra Energy and its Dynegy subsidiary.
