Technical Report: Solar PV Capacity for a 210 TPD Plasma Gasification Plant

Part 1: Defining the Total Electrical Load

The plasma gasification process requires continuous operation (24 hours a day, 7 days a week) to maintain reactor temperature and process stability. The total electrical demand must cover both the primary plasma torch load and all auxiliary equipment.

1.1 Plasma Torch Load (Primary)

Based on the previous report, the continuous electrical input required for the plasma torch system is:

Torch Capacity≈1.01 MWTorch Capacity≈1.01 MW

1.2 Balance of Plant (BOP) Load (Auxiliary)

The BOP load includes all supporting systems necessary for plant operation, such as:

• Feedstock handling (shredders, conveyors, loaders).
• Syngas cleaning and compression (pumps, scrubbers, filtration).
• Cooling systems and water circulation.
• Instrumentation, control systems, and administrative functions.

A typical industrial facility’s auxiliary load is conservatively estimated to be 

20%−25%20%−25%

 of the primary process load.

BOP Load=1.01 MW×0.25=0.2525 MWBOP Load=1.01 MW×0.25=0.2525 MW

1.3 Total Continuous Plant Load

Total Continuous Load=1.01 MW+0.2525 MW≈1.26 MWTotal Continuous Load=1.01 MW+0.2525 MW≈1.26 MW

This figure represents the instantaneous power the solar/battery system must be capable of supplying at any moment.

Part 2: Total Daily Energy Requirement

To maintain 24/7 operation, the total daily energy that the system must generate is:

Daily Energy Requirement=Total Continuous Load×24 hoursDaily Energy Requirement=Total Continuous Load×24 hours

Daily Energy Requirement=1.26 MW×24 h=30.24 MWh/dayDaily Energy Requirement=1.26 MW×24 h=30.24 MWh/day

Part 3: Solar PV Capacity Calculation

The required solar PV capacity is determined by dividing the daily energy requirement by the effective daily solar generation hours, while accounting for system efficiency losses.

Performance Ratio (PR)	0.80 (80%)	Accounts for real-world system losses from temperature, dirt, wiring, inverters, and shading.

3.2 Required Solar Capacity (kWpkWp)

The PV system capacity (

kWpkWp

, or kilowatts-peak) is calculated by:

PV Capacity (kWp)=Daily Energy Requirement (kWh/day)PSH/day×Performance Ratio (PR)PV Capacity (kWp)=PSH/day×Performance Ratio (PR)Daily Energy Requirement (kWh/day)​

Required Solar PV Capacity≈8.4 MWpRequired Solar PV Capacity≈8.4 MWp

Part 4: Battery Energy Storage System (BESS)

Since solar PV only generates power during the day (e.g., 6 hours fully, with an effective PSH of 4.5 hours), a Battery Energy Storage System (BESS) is essential to power the plant during the night and on cloudy days.

4.1 BESS Power Output (kW)

The BESS must be capable of delivering the full continuous plant load:

Required BESS Power Output=Total Continuous Load≈1.3 MWRequired BESS Power Output=Total Continuous Load≈1.3 MW

4.2 BESS Energy Capacity (MWh)

The BESS energy capacity determines the number of hours the plant can operate without solar input. For a critical, 24/7 industrial facility, 36 to 48 hours of autonomy is often recommended as a buffer for continuous cloudy weather or maintenance periods.

Using a conservative 36 hours (1.5 days) of autonomy:

Required BESS Energy=Total Continuous Load×Hours of AutonomyRequired BESS Energy=Total Continuous Load×Hours of Autonomy

Required BESS Energy=1.26 MW×36 h≈45.36 MWhRequired BESS Energy=1.26 MW×36 h≈45.36 MWh

Required BESS Energy Capacity≈45.4 MWhRequired BESS Energy Capacity≈45.4 MWh

Summary of Solar Capacity Requirements

The solar infrastructure required to power the 210 tpd plasma gasification plant as a standalone, 24/7 operation is:

Component	Metric	Required Capacity
Continuous Plant Load	Power (MW)	1.26 MW
Daily Energy Demand	Energy (MWh/day)	30.24 MWh/day
Solar PV Array	Power (MWp)	8.4 MWp
Battery Storage System	Power Output (MW)	1.3 MW
Battery Storage System	Energy Capacity (MWh)	45.4 MWh (For 36 hours of autonomy)

Conclusion:

To power the 210 tpd plasma gasification plant solely using solar energy, the project requires an estimated 8.4 MWp solar array coupled with a robust 45.4 MWh Battery Energy Storage System to ensure stable, continuous operation of the 1.26 MW load, particularly the critical 1.01 MW plasma torch system.
