Sustainable Infrastructure for Pharmaceutical Excellence

REA Technologies  successfully developed a large-scale rooftop distributed PV system for AstraZeneca Pharmaceuticals (China) Co., Ltd. across their NP and SP roof surfaces. This project demonstrates how high-output renewable energy can be integrated into specialized manufacturing environments.

Objective

The project aimed to switch the facility to renewable energy using rooftop space, reducing carbon emissions and stabilizing energy costs while ensuring reliable pharmaceutical production.

Technical Solution

To meet the facility’s significant power demands, we engineered a high-capacity solar array with a total installed capacity of 1,752.52 kWp

  • Custom Module Selection: The array consists of 2,958 monocrystalline modules, strategically combining 1,018 units (540W) and 1,940 units (620W) to optimize the available roof area.
  • Industrial Power Conversion: Seven high-capacity inverters were deployed—five 196kW units and two 250kW units—to ensure efficient energy conversion and system stability.
  • Grid Integration: The system is connected via a 20kV high-voltage point, allowing for seamless synchronization with the facility's existing industrial-grade electrical infrastructure.
  • Operational Model: The plant utilizes a "Self-consumption with Surplus to Grid" model. This allows AstraZeneca to prioritize clean energy for its own operations while contributing excess green power back to the local network.

Performance and Environmental Impact

The project is designed for decades of high-performance energy generation, providing a significant return on both environmental and financial investment.

  • Year 1 Performance: Projected generation of 1.77 million kWh
  • Long-Term Reliability: An expected 25-year annual average of 1.67 million kWh
  • Lifetime Yield: Total projected energy production of 41.63 million kWh over 25 years.

Conclusion

By transitioning to a reliable, multi-energy hybrid model , AstraZeneca is effectively insulating its operations from fossil fuel volatility and moving closer to a self-sufficient, net-zero future.

Objective

Replace high dependency on costly and polluting diesel generators with a reliable, renewable, multi-energy hybrid system to ensure 24/7 power supply and achieve significant carbon emission reduction.

Challenge

The client’s operations, critical for maintaining climate control in modern poultry houses, relied almost entirely on diesel gensets for electricity. This resulted in high operating costs, exposure to fuel price volatility, significant maintenance requirements, and a large carbon footprint. The goal was to transition the power source to renewable energy while maintaining the highest level of energy reliability.

Technical Solution

REA Technologies designed and deployed a customized, multi-energy power system incorporating solar PV and battery energy storage as the primary power sources, with the existing diesel generators retained solely for backup use.

The system is designed to provide complete day-to-day energy needs for both poultry farm sites, achieving ~1,500 kWh of clean energy generation per day. This enables the farm to operate entirely off-grid using renewables, drastically reducing the run-time of the diesel generators.

Conclusion

The REA Technologies off-grid solution enables the client to reduce thier carbon footprint  by ~410 metric tons annually and self sufficient from fossil fuel.
