The latest underground hydro construction contract issued by NHPC for the Kamala Hydro Electric Project reflects a more operationally prescriptive procurement philosophy emerging in India’s Himalayan hydro sector. The Lot-2 package consolidates tunnels, caverns, powerhouse systems and access infrastructure into one integrated contract structure.

One of the strongest signals inside this underground hydro construction contract framework is the repeated extension of bid deadlines from February to May 2026. The staggered corrigenda cycle suggests sustained bidder pressure linked to geological uncertainty, logistics exposure and qualification interpretation.

The underground hydro construction contract also highlights NHPC’s decision to preserve domestic competitive bidding despite demands for international participation. The promoter retained the DCB route even for a technically intensive Himalayan tunnelling project involving complex underground interfaces.

Another major feature of this underground hydro construction contract architecture is the growing operational focus on access-road engineering, heavy-equipment deployment and inter-package logistics coordination. NHPC revised road specifications and contractor-equipment clauses after bidder scrutiny during the pre-bid phase.

EnergylineIndia.com observes that hydro EPC risk allocation and underground powerhouse excavation complexity are increasingly reshaping contractor behaviour across Himalayan hydro procurement.

The NPCIL-led nuclear utility systems EPC package for Kudankulam Units 5 and 6 demonstrates the growing complexity of integrated nuclear infrastructure procurement. The tender combines common services, ventilation systems, mechanical utilities, and chlorination plant O&M responsibilities under a single engineering structure.

This nuclear utility systems EPC package has undergone multiple sequential extensions, with bid submission now revised to 15 June 2026. The prolonged timeline indicates continued bidder caution around technical integration and commercial risk allocation.

A defining feature of this nuclear utility systems EPC tender is the hybrid EPC-plus-O&M structure. Contractors must not only execute installation and commissioning but also maintain operational continuity for the chlorination plant after project completion.

The nuclear utility systems EPC framework also increases integration accountability because ventilation and utility systems in nuclear facilities directly influence contamination management, safety control, and operational reliability.

EnergylineIndia.com observes that the Kudankulam nuclear project reflects a wider trend toward lifecycle-based procurement in technically sensitive infrastructure sectors. Nuclear ventilation systems and balance-of-plant packages are increasingly favouring highly specialised engineering firms with multidiscipline execution capability.

The proposed GNA milestone extension charges under CERC’s draft framework have drawn objections from developers, utilities, and industry groups. This GNA milestone extension charges debate has emerged as a major regulatory issue for renewable projects.

Under the CERC GNA regulations 2022, the proposed penalty structure applies daily charges for delays in land readiness, financial closure, and commissioning milestones. Stakeholders argue these renewable project delay penalties are excessively high.

Companies including ReNew, Tata Power, ACME Solar, NTPC Green Energy, and Serentica highlighted transmission readiness delays as a major concern. The GNA milestone extension charges framework, they argue, does not sufficiently distinguish systemic bottlenecks from developer lapses.

NSEFI and other industry bodies warned that high charges could weaken project viability and investor confidence. The GNA milestone extension charges proposal may therefore affect future bidding behaviour and financing assumptions. EnergylineIndia.com highlights that the GNA milestone extension charges issue reflects broader tensions between regulatory discipline and project execution realities. The GNA milestone extension charges outcome will be closely watched across the renewable sector, Renewables, CERC India, Energy Sector, Power Projects, GNA Regulations.
