Battery Energy Storage System (BESS) Services

Scalable, High-Performance Energy Storage Solutions for Renewable Integration, Peak Shaving, and Grid Resilience

BESS Solutions

Battery Energy Storage Systems (BESS) have emerged as a crucial technology, allowing companies, utilities, and communities to store surplus energy and apply it when it is needed most.

At Finulent Solutions, we offer customized BESS design solutions to enhance energy reliability, reduce electricity costs, and support decarbonization. With our extensive experience in system design, grid integration, battery storage technologies (Lithium Iron Phosphate(LFP), Nickel Manganese Cobalt (NMC)), and Energy Management Systems (EMS), we ensure that each project meets technical, economic, and regulatory requirements while enhancing grid stability.

Frequently Asked Questions
What are the key considerations during the site assessment for a commercial BESS installation?
At Finulent Solutions, we conduct a comprehensive site assessment virtually to optimize system performance and ensure compliance with regulations. Essential considerations include land availability and topography, risk of flooding, accessibility of equipment delivery and maintenance, distance to the grid interconnection point (POI), and local zoning regulations. Environmental conditions are also assessed, and geotechnical reports are conducted to support the selection of battery technology and foundation engineering.
How does Finulent ensure BESS designs are both technically and regulatorily compliant?
Our engineers provide tailored BESS system designs that match each customer's operational objectives, be it peak shaving, energy arbitrage, or backup power. We include LFP or NMC batteries, suitable PCS units, and EMS platforms to meet standards such as IEEE 1547 1, Rule 21 2, or G99/G100 3, depending on the regulatory environment. Our system configurations, AC or DC-coupled, are designed for ease of flexibility, scalability, and grid integration.
What documents are contained within Finulent's BESS permit design package?
We offer a comprehensive permit design package to streamline regulatory approvals. It encompasses comprehensive site plans, Single-Line Diagrams (SLDs), and equipment layouts. All of these documents meet applicable zoning regulations, electrical safety standards, building codes, and utility interconnection guidelines, enabling quicker approvals from local authorities, utilities, and planning boards.
What inputs are required from the client for BESS design?
We typically need the site address & photos, current utility bills, load profile or energy usage data, Main service panel size and layout, backup requirements (partial or whole), and any future expansion plans (like EVs or solar integration).
How do you size a BESS based on energy needs to reduce costs?
We analyze your daily load curves, peak demand, and utility rate structure. Based on this, we size the system to maximize self-consumption, perform load shifting, and reduce peak-hour usage—cutting your electricity bills and optimizing ROI.
