					</table><p>The <a href="https://ser.indianrailways.gov.in/index.jsp" target="_blank" rel="noopener">South Eastern Railway</a> has invited bids for 2.059 MW grid-connected rooftop solar power systems under the Santragachi Division jurisdiction in Howrah, West Bengal.</p>
<p>The project comes under the second phase of the division’s solar initiative and covers installations across residential buildings, service buildings, railway stations, and level crossing gates within Santragachi limits.</p>
<p>Bids must be submitted by November 21, 2025. Bids will be opened on the same day.</p>
<p>The estimated cost of the project is ₹149.7 million (~$1.69 million).</p>
<p>Bidders must furnish an earnest money deposit of ₹898,500 (~$10,136).

<p>Failure to submit the guarantee within 60 days will result in termination of the contract and forfeiture of bid security. Security deposits equivalent to 5% of the contract value will also apply as per the Indian Railways General Conditions of Contract (GCC) 2022. The security deposit will be forfeited if the contract is rescinded in full under Clause 62(1) of the GCC.</p>
<p>The project must be completed within 12 months from the date of the letter of award.</p>
<p>The scope of work includes the design, supply, erection, testing, and commissioning of rooftop on-grid solar systems with capacities ranging from 1 kW to 50 kW across multiple sites. Each system will include solar modules, inverters, a balance of system components, and mounting structures.</p>
<p>It also covers a five-year comprehensive maintenance contract.</p>
<p>The total project value is divided into seven schedules covering various site types, including ₹48.2 million (~$543,851) for residential buildings, ₹31 million (~$349,913) for service buildings, ₹12.3 million (~$138,783) for railway stations, and ₹7.6 million (~$85,748) for level crossing gates, among others.</p>
