ITI Limited, a public sector undertaking under the Department of Telecommunications, has invited bids to install and commission 2 MW of grid-connected rooftop solar systems under Phase II of the grid-connected rooftop solar program of the Ministry of New and Renewable Energy (MNRE) in Bengaluru, Karnataka.

The successful bidder will also have to take care of the maintenance of the project for five years.

The rooftop solar systems will be installed in the Bangalore Electricity Supply Company (BESCOM) jurisdiction under the ‘Soura Gruha Yojane.’

A capacity of 1 MW will be installed in the 1 kW to 3 kW category (Part A), and another 1 MW capacity will be installed in the 3 kW to 10 kW category (Part B).

The last date to submit the bids is September 3, 2022. Bids will be opened on September 5.

The project’s estimated cost is ₹100 million (~$1.25 million).

Bidders must submit ₹200,000 (~$2,503) as an earnest money deposit.

Bidders may bid for a single category or both categories. The total value of the performance bank guarantee (PBG) to be submitted by the successful bidder will be the sum of the value of PBG for each part. The value of PBG for the installed capacity for each part will be calculated as below:

[PBG Value = INR (Quoted Price for Each Part) X 5% X Quoted Capacity in KWp]

The vendor should complete the design, supply, civil work, erection, testing, and commissioning of rooftop solar systems within 180 days from the issuance of the approval letter by BESCOM.

For both the categories, the minimum capacity that can be quoted is 300 kW, and the maximum capacity is 1,000 kW.

Bidders should be system integrators. They should have successfully completed installation works of a cumulative capacity of at least 500 kW of grid-connected rooftop solar projects during the last three financial years. The project should have been in service for at least one year before the bid submission date.

The minimum average annual turnover of bidders should be at least ₹40 million (~$500,644) during the last three financial years. They should have a positive net worth at the end of the last financial year.

The successful bidder will be empaneled for two years, and the contract will be extended per the MNRE and BESCOM guidelines. The empaneled vendor will provide a warranty covering the defects in equipment design, materials, and workmanship, including spare parts, for five years from the project’s commissioning date.

In April this year, Gulbarga Electricity Supply Company issued a notice inviting tender (NIT) to empanel vendors to install 3 MW of residential rooftop solar systems across seven districts in Karnataka.
