Kalasar Solar Project Starts 81.34 MW Commercial Operation

NTPC Green Energy has brought the first 81.34 MW of the Kalasar Solar Project in Bikaner, Rajasthan, into commercial operation effective September 26, marking the first operating portion of a planned 650 MW solar component associated with NTPC Renewable Energy’s 500 MW REMCL round-the-clock project.

NTPC disclosed that the 81.34 MW tranche entered commercial operation at 00:00 on September 26. The NTPC Green Energy notifications page also lists the first 81.34 MW at Kalasar as commercially operational from that date. The addition lifts the NTPC Green Energy group’s installed capacity to 11,058.57 MW, while NTPC said its wider group installed capacity stands at 91,302 MW and commercial capacity at 90,222 MW.

Kalasar Solar Project begins with an 81.34 MW tranche

The commercial-operation milestone was disclosed by NTPC in a September 26 corporate announcement. The filing identifies the operating capacity as the first part of the Kalasar Solar Energy Project at Bikaner and says the broader solar component totals 650 MW under a 500 MW REMCL round-the-clock project.

NTPC Renewable Energy Limited is a step-down subsidiary of NTPC Limited through NTPC Green Energy Limited. The filing does not state that the full 650 MW solar component is commercially operational, so the milestone should be read narrowly: 81.34 MW has reached commercial operation, while the balance remains outside this specific declaration.

Independent coverage from Business Standard reported the same September 26 commercial-operation date and the resulting increase in NTPC Green Energy group installed capacity. The outlet noted that the group’s capacity rose from 10,977.23 MW to 11,058.57 MW after the 81.34 MW addition.

The project sits inside NTPC’s round-the-clock renewable portfolio

The Kalasar capacity is described as part of a 500 MW REMCL round-the-clock project. NTPC’s disclosure does not provide enough detail to assign a specific storage capacity, wind component or hourly delivery profile to the newly operating 81.34 MW tranche, so those elements should not be inferred from the project label alone.

That distinction matters as Indian renewable procurements increasingly focus on delivery profiles rather than nameplate generation alone. Microgrid Media previously reported on NTPC Renewable Energy’s 500 MW peak-power award, where the company had not yet disclosed the generation and storage configuration it would use to meet the contracted delivery requirement.

Separately, another renewable project at Kalasar reached a commissioning milestone in August. Tata Power Renewable Energy commissioned 190.5 MW of solar generation with 115 MWh of battery storage at the same Rajasthan locality. That Tata Power Kalasar project is a different development and is not part of NTPC’s September 26 declaration.

Commercial operation is a concrete project milestone

Commercial-operation declarations are more significant than early development announcements because they identify capacity that has moved into an operating status under the developer’s reporting framework. In this case, the first 81.34 MW is now part of NTPC Green Energy’s installed base rather than simply planned capacity.

The parent-company disclosure also provides a useful scale reference. NTPC reported total group installed capacity of 91,302 MW after the declaration, while the renewable-focused NTPC Green Energy group reached 11,058.57 MW. The 81.34 MW addition is therefore incremental at group level, but it marks the start of operations for a much larger 650 MW solar component.

What to watch next

The next material developments will be additional commercial-operation declarations for the remaining Kalasar capacity and any project-level disclosure that clarifies how the wider REMCL round-the-clock obligation is being met. The current filing does not specify a completion date for the full 650 MW solar component or provide a detailed technology configuration beyond the solar capacity.

For now, the Kalasar Solar Project has crossed a verifiable operating threshold with 81.34 MW online. Future tranches will determine how quickly NTPC Renewable Energy converts the remainder of the planned solar component into commercial capacity.
