May 28, 2025. By News Bureau

For solar power plants, we support the full lifecycle—from feasibility and land acquisition to engineering, execution, commissioning, and handover. We also guide clients through complete setup, including backward integration from modules to ingots, said Atul Kamathi, Partner (Head – Renewable Solutions), Octago Advisory Solutions LLP in an interview with Energetica India.

Que: What is Octago and what sets it apart in the consulting space?

Ans: Octago is a strategic consulting firm with over a decade of combined experience across the industry, top consulting firms, and sectoral leadership. What sets us apart is our deep sector expertise, particularly in renewable energy, and our ability to provide end-to-end, customised solutions. We blend technical insight with business strategy—helping clients navigate complex challenges and drive long-term value.


Que: What services does Octago offer in the renewable energy sector?

Ans: We offer comprehensive consultancy services in solar and biogas. For solar power plants, we support the full lifecycle—from feasibility and land acquisition to engineering, execution, commissioning, and handover. In solar manufacturing, we guide clients through complete setup, including backward integration from modules to ingots. For biogas, we provide feasibility studies, strategic land planning, offtake structuring, and by-product optimisation, along with support in accessing government incentives.


Que: How does Octago help overcome the challenges in solar cell manufacturing in India?

Ans: Solar cell manufacturing in India faces challenges such as high capital expenditure, technology complexity, and the need for precision-controlled environments. Octago addresses these through strategic planning, cost optimisation, and technical expertise. We help clients access and refurbish international cell line assets—cutting setup costs by up to 20 percent—and provide in-house design and engineering for systems like CDS, PBGS, UPW, and more. We also specialise in upgrading older lines to advanced technologies like PERC or TOPCon.


Que: What market opportunity does Octago see in the current manufacturing landscape?

Ans: The current instability in neighbouring countries that traditionally dominate cell manufacturing has opened up access to high-quality tools and manufacturing assets at significantly lower costs. This presents a major opportunity for Indian players. Octago helps clients capitalise on this by sourcing, refurbishing, and commissioning equipment while also managing risk through robust business planning and technological guidance.


Que: How is Octago aligned with India’s sustainability and Net Zero goals?

Ans: At Octago, our mission closely aligns with India’s Net Zero ambitions. We don't just offer technical advisory; we provide holistic business planning from inception to exit strategy. As a proud Indian firm, we are committed to contributing meaningfully to Prime Minister Narendra Modi’s vision of a self-reliant and sustainable India.


Que: Does Octago offer services beyond renewable energy?

Ans: Yes, beyond renewables, Octago provides management consulting in growth strategy, process optimisation, fundraising, and ESG. Our proprietary platform KnowBiz offers 360° business and risk intelligence, and our integrated risk management solutions help clients make data-driven, future-ready decisions.
