The Lakshadweep Electricity Department has invited expressions of interest for rate contracts and to empanel vendors for setting up a 2,107 kW rooftop solar project with a 5,525 kWh battery storage system on government buildings in Lakshadweep.

The last date to submit bids is June 4, 2026. Bids must be opened on June 5.

Successful bidders must submit performance security equal to 5% of the contract value.

The scope of work covers site survey, design, engineering, supply, installation, testing, and commissioning of the project.

It also entails operation and maintenance (O&M) for 10 years.

The project also encompasses the installation of a battery management system and an energy management system.

Successful bidders must ensure warranty coverage and part replacement during the defect liability and O&M periods.

The empanelment will be valid for three years.

The solar system must be configured to export zero energy during peak generation periods and to discharge up to 25% of depth of discharge during peak load periods. The inverter and energy management system must be able to enforce export limits in accordance with grid requirements.

Successful bidders must ensure system availability of at least 98% annually.

They must use solar modules included in the Approved List of Models and Manufacturers.

The battery storage system must be designed for a minimum of 6,000 cycles and a minimum depth of discharge of 80%. It must also ensure a minimum round-trip efficiency of 85%.

Bidders must have designed, supplied, installed, and commissioned grid-connected rooftop solar projects with a cumulative capacity of at least 500 kW in the last five years or on the last day of the month preceding the month in which EoI is invited.

They should have also executed projects in islands and remote coastal locations.

Additionally, bidders must have executed at least one solar project of at least 400 kW, two projects of 250 kW, and three projects of 200 kW. The projects must have been operational for at least a year.

Successful bidders must be empaneled under the Ministry of New and Renewable Energy to  implement rooftop solar projects.

Bidders must have supplied, installed, tested, commissioned, and integrated a battery storage project within a solar project or as a standalone battery storage project, with a cumulative installed capacity of at least 100 kWh in the last five years.

Additionally, bidders must have executed at least one battery storage project of at least 100 kW, two projects of 50 kWh, and three projects of 30 kWh. These projects must have been operational for at least a year.

Bidders without battery storage project experience must submit an undertaking to execute the project’s storage component through an original equipment manufacturer or an authorized technology partner that has designed, supplied, and commissioned battery storage projects.

Bidders must have a minimum annual turnover of at least ₹80 million (~$840,000) in the last three financial years and a net worth of at least ₹50 million (~$525,000) in the last financial year.

Last year, the Lakshadweep Electricity Department invited bids to install 2,107 kW of rooftop solar systems, with a 3 kWh battery energy storage system for each kW of installed capacity, on government buildings.

In 2024, Solar Energy Corporation of India invited bids to commission 1,385 kW of grid-connected solar power projects, with 394 kW/1,117 kWh of battery energy storage systems, in Lakshadweep under the renewable energy service company mode.
