What is being bought for Mahi Banswara and Kudankulam right now?

Why is Gujarat building a 600 MW solar plant for Telangana and Punjab?

NHPC is building a 600 MW solar project at Khavda RE Park in Kutch, Gujarat, at a cost of ₹4,295.6 crore including five years of operation and maintenance. It is under construction now, with commercial operation estimated for September 2027. None of the power stays in Gujarat. 500 MW is contracted to Telangana’s Southern and Northern distribution companies and 100 MW to Punjab State Power Corporation, evacuated through a 15 km, 400 kV line to the KPS-III interstate substation.

This is what the central public sector undertaking scheme is actually for. Kutch has the irradiance, the land and almost no local demand. Telangana and Punjab have the demand and neither the land nor the sunlight. The project is a transmission decision as much as a generation one, and the 15 km of 400 kV line is the part that makes the long-distance sale possible.

The technical shape tells you how the economics work. The plant runs a DC to AC ratio of 1.5, meaning roughly 900 MWp of direct current capacity is being installed to deliver 600 MW alternating current at the meter. That is heavy oversizing, and it is what you do when land and modules are cheap and you want a flatter output curve across the day rather than a sharp noon peak. Design energy is 1,766.55 million units at a capacity utilisation factor of 33.59%.

NHPC states the commercial operation date as estimated. Treat September 2027 as the developer’s own projection, not a commitment.

What is being bought for Mahi Banswara and Kudankulam right now?

Components, which is the tell. On our count of 28 August, four of the six live energy tenders on the national portal were nuclear, and not one of them was a feasibility study or a concept design. ASHVINI is seeking an engineering and construction prime for the nuclear island at the Mahi Banswara plant in Rajasthan, the largest scope on the board. NPCIL is separately buying three packages for Kudankulam Units 5 and 6: the main electrical works, a combined package for common services, ventilation and mechanical plant, and one for material handling equipment.

Component-level procurement means both projects are past financial close and into build. This is not a pipeline, it is a construction programme. The qualification barrier around nuclear work means the realistic bidder list is short, stable and knowable, which is unusual: most Indian infrastructure categories carry a long tail of possible bidders. This one does not.

The unbundling at Kudankulam is worth noting on its own. Three separate packages for one pair of units means the operator is managing interfaces itself rather than handing a single prime the whole scope, which opens the work to specialists who could never carry a turnkey nuclear contract.

What solar work is GAIL buying, and why are the two packages nothing alike?

GAIL has two solar tenders open and they sit at opposite ends of an asset’s life. One covers building a 600 MW solar plant and then running it, the largest renewable scope open on the portal and the nearest deadline. The other adds 1.2 MWp of capacity to the 5 MW plant it already operates at Ramgarh.

The Ramgarh job is quietly the more interesting. India’s earliest utility-scale solar is now old enough to uprate. The site, the grid connection, the land and the permits already exist, so what is being bought is higher-efficiency modules, inverter replacement and structural work on a live asset. The buyer is an operations team working to an availability constraint, not a development team working to a tariff.

That is a different sale with a different cycle. Greenfield solar is won on levelised cost and financing. Uprating is won on how little generation you lose while you do it, and on whether you can work around an operating plant.

How much more can you get from a solar plant without buying more land?

About a quarter. GAIL is adding 1.2 MWp of direct current capacity to an existing 5 MW plant at Ramgarh, on the same site, the same connection and the same permits.

Land and grid connection are the two things that take longest and cost most in Indian solar. An uprate buys capacity that skips both. For an operator with a fleet of plants commissioned before 2018, the cheapest megawatts available are the ones already sitting on land they own.

Where does India’s grid-scale energy work actually get tendered?

Not centrally. NTPC’s green arm has been letting wind and solar packages at Bellary, Davangere, Anantapur and Dhule. None of them appeared on the national portal. They sit on NTPC’s own listing, because NTPC runs its own procurement system. Separately, SECI blocks automated access to its listing altogether.

We tested whether the work was simply filed under a different heading. It is not. The electrical category is street lighting for the Municipal Corporation of Delhi, air conditioning for the Reserve Bank and terminal electricals for the Airports Authority. Solar, wind and battery barely register in it, and electric vehicle charging and green hydrogen do not appear at all.

The buyers that are present on the central portal are a different population entirely: an explorer, a biofuels producer, a regional utility, a river board. Useful if you sell upstream. Useless if you sell generation.
