NTPC Green Energy has invited bids for the deployment of a Qualified Coordinating Agency (QCA) to provide forecasting, scheduling, and punching of finalized schedules into the relevant grid portal and aggregation services for its 250 MW solar power project at Anantapur, Andhra Pradesh.

The last date to submit bids is July 22, 2025. Bids will be opened on the same day.

Bidders must submit 5% of the monthly billed service charges as a security deposit.

The selected bidder must provide QCA services for 12 months, which may be extended for an additional six months. There will be a defects liability period for one year.

The scope of work encompasses the collection of real-time data on power generation and the installation of modem-based energy meters.

Alternatively, bidders must make arrangements for real-time data from the supervisory control and data acquisition systems site, as well as the analysis of all available static and historical data.

It also entails the integration of weather data and the setup of the forecast model, as well as the collection of availability data for solar inverters/transformers, and the collection of weather data from reputable forecasting agencies.

Successful bidders must provide a day-ahead/week-ahead schedule/forecast as prescribed by the regional load dispatch centre (RLDC) or the state load dispatch centre (SLDC).

The schedule will be for 96 blocks of 15 minutes each, from 00:00 hours to 10:00 AM the next day.

They must provide intra-day revisions to the forecast/schedule as per the provisions of the applicable deviation settlement mechanism (DSM), and coordinate and implement the revised schedule.

The scope of work encompasses the provision of a web-based application for the live display of real-time data and graphical trends of the latest schedule and actual plant generation.

All data collected related to the DSM mechanism during the contract period must be stored by the bidder for the duration of the contract.

The selected bidder must provide 24/7 support services and establish a team of renewable resource analysts, modeling statisticians, energy modelers, and a 24/7 operation and monitoring team.

The QCA must coordinate and facilitate power scheduling for all power generators participating in the aggregation at the pooling station with the relevant RLDC. It must also undertake commercial settlement of deviations with the relevant RLDC.

The selected bidder will establish and maintain a round-the-clock coordination center for operational coordination with RLDC and generating stations.

The QCA will be responsible for maintaining records and accounts of the time-block-wise schedules, the actual generation injected, and the deviation, for both the pooling station and individual generators.

The selected bidder must also share the data with the power generators.

The project also entails maintaining a weekly record of de-pooling of DSM by RLDC or a renewable energy agency for the aggregated capacities as per schedule. A record of the actual power generation of individual generators must be maintained to determine the DSM calculation, including payable or receivable amounts based on individual under-injection or over-injection.

The QCA must verify the pool DSM with actual data and identify discrepancies.

It must share the power generator’s data, including the de-pooled DSM impact. It must also share the pool data of other power generators, as published by RLDC, through a real-time portal updated weekly.

In June, the Haryana Electricity Regulatory Commission amended the formula for calculating the net worth criteria for selecting a QCA.
