What sectors does Growthifye cover?

We work across the clean-energy value chain — utility-scale solar and wind, battery energy storage (BESS), power transmission networks, and the green financing structures that fund them.

Do you handle both engineering and financing?

Yes. Our differentiator is combining engineering-led advisory and EPC with an in-house green financing and debt syndication desk, so technical and financial workstreams stay aligned all the way to financial close.

Can you support transmission and grid connection?

Absolutely. We engineer HV substations and transmission lines, run grid connection and evacuation studies, and manage the interface with utilities and grid operators.

What does green financing include?

Sustainability-linked loans, green debt, blended finance and non-recourse project finance — structured, syndicated and negotiated to secure competitive, long-tenor capital.

How do we start working with you?

Share your project or mandate through the contact form or WhatsApp. We'll set up a discovery call and outline a tailored engagement across advisory, engineering, EPC or financing.

Timeline

2007-2010
Northern grid capacity constraints and Chhattisgarh generation clusters identified as candidates for a dedicated HVDC bipole.
2011-2013
Route survey, converter-station siting and inter-state right-of-way alignment finalised across Chhattisgarh, MP, UP, Haryana.
2014-2016
EPC packages for converter stations and DC line towers awarded; approx. 6 GW ±800 kV bipole configuration confirmed.
2017-2019
Tower erection and stringing executed in phases; land acquisition and forest clearances caused localised delays.
2020-2021
Converter station commissioning and system integration testing carried out in stages.
2022 onward
Full commercial operation achieved, supporting bulk power transfer and grid stability studies for northern states.

Why it matters

The Champa–Kurukshetra ±800 kV HVDC link is one of India's largest point-to-point bipole schemes, moving approx. 6 GW of central-Indian generation over approx. 1,365 km to the northern grid. For developers, lenders and utilities it is a template for converter-station procurement, right-of-way management across multiple states, and the interface between bulk thermal/RE evacuation and a constrained northern load centre. Its scale, sequencing and cost overruns offer transferable lessons for every future UHVDC and green-energy-corridor bid in India.

The India angle

For India's TBCB and PGCIL-style bulk transmission tenders, this project shows why bid documents must fix RoW responsibility, forest-clearance timelines and converter-technology specifications before financial close. Lenders increasingly ask for grid-code compliance studies (CEA/CERC) and firm interconnection agreements upfront. Green financing structures for future HVDC corridors linked to renewable energy zones should mirror this project's phased-milestone drawdowns to align disbursement with converter-station completion, not just tower erection.

What it teaches

Engineering, procurement and finance lessons

Converter-station lead times drive the critical path

Long-lead thyristor valves, transformers and cooling systems for ±800 kV stations often dictate overall schedule more than line stringing; developers should lock manufacturing slots and factory-acceptance milestones early in the EPC contract.

Multi-state RoW needs a single coordination desk

Corridors crossing four or more states face fragmented forest and land clearances; a dedicated inter-state liaison cell reduces delay risk that otherwise cascades into financing cost overruns.

Bipole redundancy shapes tariff and risk allocation

Bulk transfer schemes at this scale require clear force-majeure and availability-based tariff structures so lenders can price single-point-of-failure risk on the converter stations, not just the line.

Grid integration studies must precede award

Northern grid absorption capacity and short-circuit level studies should be finalised before final investment decision to avoid re-engineering of filter and reactive power compensation packages.

Sequencing EPC packages avoids idle capital

Splitting converter and line packages with staggered milestones keeps working capital productive and allows partial energisation for early revenue recognition.
