Rincon Long Duration Multi-Storage Solar Microgrid
Demonstrates integration of long-duration flow battery and flywheel systems with a commercial microgrid
The project agreement was executed on September 22, 2020. The recipient has begun preparing the SDG&E interconnection application, and microgrid design engineering is in progress.
This project will demonstrate the integration of two types of non-lithium ion energy storage technologies: vanadium redox flow battery and flywheel storage systems, which will each provide 400kW of load for up to 12 hours. The two technologies will be interconnected with solar PV to create a microgrid that will provide resiliency and cost savings for multiple buildings, including a wastewater treatment plant and an emergency public shelter.
The project will provide onsite distributed renewable energy resources and energy storage capacity for load shifting to reduce customer electricity costs by nearly $686,645 in Year 1 and $18.944 million over the project’s 25-year lifetime.
Environmental & Public Health
The project will provide onsite distributed renewable energy resources and energy storage capacity for load shifting to displace utility-delivered electricity responsible for over 1 million kg of greenhouse gases in the first year of operation.
The project will increase tribal energy security and self-reliance by providing onsite renewable generation and energy storage resources that displace consumption of imported electricity and standby diesel generation fuel. The project will also protect customer loads from Public Safety Power Shutoffs and other long-duration outage events.
