One-Cycle Control, Inc. (OCC) has completed multiple design reviews and iterations for the 15 kW Silicon-Carbide enabled OCC-MORBUGs. The final design is near completion. OCC has prepared a draft Factory Test Plan and is proceeding with subsystem testing of the components for the MORBUGS trailer. These components include the photovoltaic array structure, batteries, wind turbines, inverter, human machine interface, and trailer. OCC will verify that the product meets the design intent and is ready to deliver to customers.
The One-Cycle Control, Inc. (OCC) Mobile Renewable Backup Generation System (MORBUG) carrier system provides an alternative solution to traditional fossil-fuel backup generators. The OCC-MORBUG is designed as an integrated system that is locally self-sufficient. Powered by solar photovoltaics and wind coupled with onboard battery storage, the system is zero-emission, quiet, and mobile, allowing it to be transported to locations when and where power is needed. The system is also designed to generate three phase power (single/three phase AC and DC) which is often required by industrial and commercial customers. The MORBUG carrier has been designed to operate during PSPS events lasting 48 hours, with a power rating of 15kW.
The OCC-MORBUG will provide quiet and pollution free backup power when/where ratepayers need it. For the avoided CO2 emissions, assuming PSPS usage is 10 occurrences per year, lasting 48 hours at a time, 480 gallons of gasoline would be avoided. Each gallon of gas equals approximately 20 pounds of CO2, resulting in a 9,600 pounds of CO2 avoided per year, which equals approximately 5 tons of CO2 per year, per MORBUG.
Utilization of MORBUGs systems is expected to reduce cost compared to using a fossil-fuel generator that requires a continuous supply of costly fossil fuel and multiple fuel-burning trips to the hardware store or gas station. It is estimated that the avoided grid electricity usage during PSPS events is 2,880 kWh/year and non-PSPS events is 10,000 kWh/year for a total of 10,000 kWh/year resulting in a net saving of $1,500.
The OCC-MORBUG carrier is the first to provide clean energy for single, three-phase loads, plus DC loads with zero-emission for mobile back up. The OCC-MORBUG carrier is based on Silicon-Carbide-enabled OCC-4 wire inverter technology to achieve high efficiency, high reliability, high power density, high flexibility of loading. The OCC-MORBUG carrier features a rugged design for on/off-highway and dirt road, on-board PV, and wind for quick deployment.
OCC-MORBUGs would create opportunities for low-income (LI) & disadvantaged communities (DAC) groups. Out of 5 secured sites, 4 are located in LI and 2 are located DAC communities. Furthermore, subcontractor Chula Vista Electric's pursues outreach to high schools particularly in LI/DAC communities and encourages their pursuit of electrical trades from ETI-San Diego that provides employment as part of their training. OCC is located in a LI/DAC area.
Utilization of MORBUGs systems is expected to reduce costs compared to use cases requiring a fossil-fuel generator and multiple trips to continuously supply fuel. The project aims to acheive a five year break even cost of the unit, based on the avoided cost of fuel and the reduced cost of maintenance.
