350kW + 1MWh BESS Project in Peru for Supermarket

When the power goes out, a supermarket doesn’t simply lose electricity. It risks food spoilage, customer dissatisfaction, operational interruptions, and significant revenue loss.

To address these challenges, Namkoo has successfully completed a 350kW + 1MWh BESS project for a supermarket in Peru, providing a reliable off-grid solar energy solution that keeps the business running even during grid outages and severe weather conditions.

As Namkoo’s eighth supermarket solar-storage project across Central and South America, this installation demonstrates how advanced energy storage technology can help supermarket owners reduce costs, improve energy reliability, and protect business continuity.

Project Overview

System Configuration

• 350kW Rooftop Solar PV System

• 1MWh Battery Energy Storage System (BESS)

• All-in-One 40ft Energy Storage Container

• Off-Grid Solar + Storage Solution

• Plug-and-Play Installation Design

The heart of the project is a highly integrated battery energy storage system container, which combines key energy storage components into a single factory-assembled unit.

Once the rooftop solar system was installed, the supermarket only needed to connect the energy storage container to activate the entire off-grid system.

This plug-and-play design dramatically reduced installation complexity, shortened commissioning time, and enabled rapid deployment.

What Is a BESS and Why Is It Important for Supermarkets?

Many business owners ask, “What is a BESS?”

A Battery Energy Storage System (BESS) stores electricity generated by solar panels and releases it when needed. Instead of relying entirely on utility power, businesses can utilize stored renewable energy to power critical operations around the clock.

For supermarkets, a BESS provides several important benefits:

• Continuous refrigeration for fresh and frozen products

• Stable power supply during grid outages

• Reduced electricity costs

• Protection against voltage fluctuations

• Greater energy independence

In regions where utility reliability can be affected by severe weather or aging infrastructure, energy storage becomes an essential business asset rather than a luxury.

Common Electricity Challenges Faced by Supermarkets

Through our extensive experience across Latin America and the Caribbean, Namkoo understands the most common pain points supermarket owners face.

❄️ Risk of Food Spoilage During Power Outages

Refrigerators and freezers are among the most critical assets in a supermarket.

Even a short outage can result in inventory losses, wasted products, and financial damage.

💰 Rising and Unpredictable Electricity Costs

Energy expenses often represent a significant portion of supermarket operating costs.

Utility rate fluctuations can negatively impact profitability and make budgeting difficult.

⛈️ Grid Instability and Severe Weather Events

Many regions in the Americas experience power interruptions caused by storms, hurricanes, and aging electrical infrastructure.

These disruptions can force supermarkets to temporarily close or operate at reduced capacity.

Customized Battery Energy Storage System Design for the Americas

A successful energy storage project requires more than simply installing batteries.

Every battery energy storage system design must be adapted to local operating conditions.

Namkoo engineers specifically design systems for the Americas market by considering:

Local Voltage Standards

Different countries operate under different grid voltages and frequency requirements. Our systems are configured to ensure full compatibility with local utility infrastructure.

Suitable Inverter Selection

Choosing the correct inverter model is essential for system performance, reliability, and grid integration.

Namkoo selects inverter technologies based on local utility standards and project requirements.

Regional Installation Specifications

Installation practices must comply with local engineering standards, electrical regulations, and environmental conditions.

This ensures safe and reliable long-term operation.

Rapid Deployment with Local Technical Support

One of the key advantages of working with Namkoo is our strong regional support network.

To ensure successful implementation, the Namkoo Caribbean technical team traveled directly to Peru to conduct site surveys, oversee installation, and provide technical guidance throughout the commissioning process.

This hands-on approach helped the customer:

• Accelerate project completion

• Reduce installation risks

• Ensure optimal system performance

• Minimize operational downtime

Results: Reliable Power and Lower Operating Costs

Since commissioning the solar PV and BESS system, the supermarket has experienced significant operational improvements.

Reliable Business Continuity

Even during utility outages, the supermarket remains fully operational.

Protected Refrigeration Systems

Critical refrigeration equipment continues running, preserving food quality and preventing inventory losses.

Reduced Electricity Costs

The system maximizes solar energy utilization and reduces dependence on expensive utility electricity.

Improved Revenue Stability

By avoiding disruptions caused by power failures, the supermarket maintains normal customer service and consistent sales performance.

Why More Supermarkets Are Choosing BESS Solutions

Across Latin America, businesses are increasingly investing in energy storage to gain control over their electricity supply.

A properly designed BESS can:

• Improve energy security

• Reduce operational expenses

• Increase solar self-consumption

• Protect revenue during outages

• Support long-term sustainability goals

As electricity costs continue to rise, energy storage is becoming a strategic investment for supermarket operators seeking greater profitability and resilience.

FAQ

What is a BESS?

A BESS (Battery Energy Storage System) stores electricity generated from renewable sources such as solar panels and supplies power when needed, improving energy reliability and reducing electricity costs.

Why do supermarkets need energy storage systems?

Supermarkets rely heavily on refrigeration and lighting. Energy storage ensures these critical systems remain operational during power outages and helps lower electricity expenses.

What is a battery energy storage system container?

A battery energy storage system container is a fully integrated energy storage solution housed inside a standardized container. It simplifies installation, transportation, and deployment.

How does a plug-and-play BESS work?

Factory-integrated systems arrive pre-assembled and pre-tested. After connection to the solar system and electrical infrastructure, the system can be commissioned much faster than traditional installations.

Can a BESS operate completely off-grid?

Yes. When properly designed and combined with solar PV generation, a BESS can provide reliable off-grid electricity for commercial facilities.
