The 0.5 MW rooftop solar project will be integrated with a 1 MWh battery energy storage system to improve power reliability, reduce grid dependence and deliver an estimated payback period of three to four years.
Loom has announced that it has secured a turnkey solar-plus-battery energy storage system (BESS) project for Rajvansh Associates Rice Mill in Mahasamund, Chhattisgarh.
The project combines a proposed 0.5 MW rooftop solar installation with a 1 MWh battery storage system to help the industrial facility optimise electricity consumption and improve power reliability.
The project comes as energy-intensive industries increasingly explore integrated renewable energy and storage solutions to manage electricity costs and reduce dependence on conventional grid power.
Here are five key things to know about Loom’s solar-plus-storage project in Chhattisgarh.
1. 0.5 MW Solar Project Integrated with 1 MWh Battery Storage
The project will feature a proposed 0.5 MW DC rooftop solar installation, equivalent to 450 kW AC capacity, integrated with a 0.5 MW/1 MWh BESS.
The battery system will comprise four CAML All-in-One units, each rated at 125 kW/261 kWh.
For the solar installation, Loom will deploy its SHARK 625 Wp N-Type TOPCon G12R Dual Glass Bifacial solar panels, supported by three Fusion 150 kW grid-tied photovoltaic inverters.
2. Battery Storage to Extend Solar Power Availability Beyond Daylight Hours
The integrated system is designed to maximise the utilisation of solar electricity throughout the day and night. During daylight hours, solar generation will meet the rice mill’s operational electricity requirements while charging the battery storage units.
From 5 PM onwards, stored electricity will be discharged to support operations through the night and until the following morning. During grid interruptions, the available solar generation and battery storage will provide additional power support. The system is designed to automatically transition to grid electricity once the battery reaches its designated 90% discharge threshold.
3. Projected Payback Period of Three to Four Years
According to Loom’s estimates, the integrated solar and storage installation is expected to deliver a payback period of approximately three to four years.
The system is projected to support around 900 units of electricity daily, representing an indicative energy value of ₹9,000 per day. Based on these estimates, the annual energy value could reach approximately ₹32.4 lakh.
However, actual savings and project returns will depend on electricity tariffs, consumption patterns, system performance and operating conditions.
4. Scope for Additional Battery Storage Capacity
The project has provisions for future expansion through an additional proposed 250 kW/522 kWh battery energy storage system. This expansion could increase the facility’s energy storage capacity and provide greater flexibility in managing electricity demand and grid interruptions.
Loom’s latest project builds on its experience with industrial solar-plus-storage installations. The company has previously executed a 300 kW solar project integrated with a 375 kW/783 kWh BESS in Uttar Pradesh.
That installation reportedly generates around 1,500–1,600 units of electricity daily to support the manufacturing facility’s operations.
5. Commissioning Targeted for December 2026
Loom will handle end-to-end turnkey execution of the Chhattisgarh project. Its responsibilities will cover system design, equipment supply, installation, commissioning, testing, operation and maintenance. The project is scheduled to be commissioned by December 2026.
Solar-Plus-Storage Solutions Gain Relevance for Industrial Consumers
The project highlights the growing role of battery energy storage systems in commercial and industrial renewable energy applications.
For facilities such as rice mills, food processing units and manufacturing plants, combining rooftop solar with battery storage can help align renewable electricity generation with operational demand, particularly during evening and night-time hours.
As Indian industries look for ways to improve energy efficiency and manage grid dependence, integrated solar-plus-storage systems could become an important part of their energy transition strategies.
