Maximizing Renewable Potential with On Grid Engineering

In today’s evolving energy landscape, grid stability and reliability depend on robust energy storage systems. On Grid Engineering provides end-to-end electrical engineering services for BESS projects — whether integrated into a renewable plant or deployed as a standalone system. Our team brings deep expertise in electrical design, protection, studies, and interconnection to deliver storage solutions that enhance system flexibility and ensure grid compliance.

Advanced BESS Adaptability

Our BESS designs adapt to evolving industry standards, site constraints, and emerging technologies. We perform thorough site feasibility assessments, model lithium-ion and alternative chemistries, and size storage based on anticipated charge/discharge cycles. From capacity optimization to control strategy development, On Grid Engineering delivers solutions that address both short-duration peak shaving and long-duration energy shifting requirements.

BESS Design Services

On Grid Engineering offers a full suite of multi-disciplinary BESS engineering services to optimize performance, reliability, and cost. Our core service areas include:

BESS Electrical

  • Medium Voltage (MV) & DC Electrical System Architecture
  • Auxiliary Power & Control System Design
  • Equipment Specification & Rack Layout Coordination
  • Power System Studies & Protection Coordination
  • SCADA & Energy Management System Integration

Auxiliary Systems & Controls

  • Battery Management System (BMS) Configuration
  • Power Conversion System (PCS) Communication & Controls
