VSL Renewable Services has won the operation and maintenance (O&M) contract for 810 MWp of NTPC Green Energy’s (NGEL) 1,864 MW solar power projects in Andhra Pradesh, Madhya Pradesh, and Rajasthan.

The O&M will be for a period of 36 months.

The tender was floated in January 2025.

VSL emerged as the lowest bidder for both Lot 1 (1,054 MWp) and Lot 2 (810 MWp). However, according to NTPC’s tender conditions, only Lot 2 was awarded to the company.

The project will leverage artificial intelligence and Internet of Things-based platforms for anomaly detection, performance optimization, and predictive diagnostics for the O&M of these projects.

VSL must ensure consistent energy output with contractual performance guarantees.

The company has devised state-specific strategies for O&M. In Rajasthan, VSL will provide dust mitigation and thermal management solutions in arid zones, and in Madhya Pradesh, it will ensure grid synchronization and terrain-specific O&M services. It will also include corrosion control and coastal resilience planning for Andhra Pradesh.

VSL must attend to string outages daily, restore inverter tripping, and respond to all breakdowns/tripping. It must also restore the system in the minimum possible time.

According to the tender, the successful bidder must man the control room round the clock.

VSL must also submit periodic reports to NGEL on the energy generation and operational condition of the solar projects and their associated equipment.

The contract also covers cleaning of drains, cable trenches, and box culverts.

It must also include an annual maintenance contract, spare supply agreement, and an operational level agreement for components such as battery charger items, uninterruptible power supply, and power packs to ensure critical equipment availability.

VSL Must perform annual testing of all spare equipment and in-service equipment, and ensure a minimum of 18 module cleaning cycles annually.

In July 2025, NGEL invited bids for the O&M of a 160 MW solar project at Jetstar, Rajasthan, for two months.

In the same month, NGEL invited bids for the comprehensive O&M of its 250 MW Shimbhu ki Bhurj-I solar project for two months in Rajasthan.
