Background: Off-grid energy is becoming a new direction in the US energy transition
As the US energy mix accelerates toward cleaner and more distributed energy, more businesses and real estate developers are interested in developing energy-sufficient projects. Off-grid battery hybrid power systems are gaining widespread adoption in remote areas, energy-independent communities, and areas with limited grid access.
Against this backdrop, a US real estate developer partnered with SCU to build an independent energy system integrating photovoltaic power generation, diesel generators, and energy storage to provide a stable, green energy supply for its multiple high-end residences and supporting buildings.
Client Needs: The dual challenges of stability and sustainability
The project is located in the western United States, where grid coverage is limited, electricity prices are high, and power supply fluctuates frequently. The client set the following goals in their project planning:
- Achieve energy self-sufficiency: The project needed to operate completely off-grid to meet daily power needs.
- Improve power supply stability: PV output is significantly affected by the climate, requiring stable energy support.
- Create a green image: The project needed to embody environmental protection and sustainable development concepts, adding value to the property.
- Reduce operating costs: Reduce diesel consumption through energy storage and an energy optimization control system.
SCU Solution: Hybrid Energy Storage Solution
To meet the client’s off-grid needs, SCU configured a high-performance energy storage system that complements the PV array and diesel generators for multi-energy operation. The system utilizes an advanced battery management system (BMS) and energy management system (EMS) for intelligent energy scheduling and load balancing.
System Features
Highly Integrated Design: The energy storage system integrates batteries, PCS, EMS, fire protection, and temperature control systems, enabling easy deployment and simplified maintenance.
PV Priority Strategy: PV power generation is prioritized for power generation, with the energy storage system storing excess energy.
Intelligent Diesel Generator Scheduling: When PV and energy storage are insufficient, the diesel generator automatically starts and stops to ensure a continuous power supply.
Energy Optimization Control: The system automatically optimizes scheduling based on load demand and energy prices, achieving economical operation.
Project Achievements: Integration of Green Energy and Real Estate Value
- Stable Power Supply: The energy storage system effectively smooths fluctuations in PV power generation, ensuring a 24/7 stable power supply for the community.
- Diesel Savings: Compared to traditional diesel generator systems, annual diesel consumption is significantly reduced.
- Economic Benefits: Energy costs are significantly reduced, and system maintenance and operation are more efficient.
- Enhanced Green Image: The project’s use of clean energy solutions has enhanced the overall market appeal and brand value of the property.
