Established in 2017, Revayu Energy has steadily transitioned from a niche micro wind company to an innovative renewable energy player, providing solutions across the solar, wind and battery storage segments. With an expanding portfolio across India and West Asia, and marquee clients like Bharat Petroleum Corporation Limited (BPCL), PepsiCo and the Taj Group, the company is making waves in the hybrid and tribrid renewable space. In an interview with Renewable Watch, Prateek Gupta, Founder and Chief Executive Officer, Revayu Energy, discussed the company’s journey, business innovations, recent projects and the company’s future road map. Edited excerpts…
Could you walk us through Revayu Energy’s journey from inception to where you are today?
We started Revayu Energy in 2017 with a vision to bring micro wind technology to the Indian renewable landscape. Back then, distributed wind energy was a niche concept, especially for small-scale and remote applications. Over time, we recognised the potential in hybridising technologies and moved into solar-wind hybrid solutions.
We had applied for three patents – two in the US and one in India – and are currently filing two more related to our tribrid innovation. Today, our portfolio includes PPA-based rooftop solar projects, engineering, procurement and construction (EPC) services, and hybrid and tribrid systems. Our clients range from multinationals like PepsiCo, Procter & Gamble and Heineken’s United Breweries Limited to public sector undertakings such as BPCL and the Defence Research and Development Organisation. For BPCL, we recently implemented a tribrid renewable-powered fuel station.
What is the scale of Revayu’s operations today and your near-term targets?
As of FY2024-25, our installed and under-execution capacity stands at about 60 MW. In FY2025-26, we expect to scale this up to 250 MW by implementing a combination of commercial and industrial (C&I) rooftop solar systems, hybrid systems and utility-scale EPC projects. We have a pipeline for a 10-fold growth in revenue in FY 26.
We have also recently secured a 70 MW EPC order for a private client. This is our second utility-scale project after a 48 MW project executed for the Aditya Birla Group last year.
Could you elaborate more on the tribrid model project implemented for BPCL?
The tribrid renewable model integrates solar, micro wind and battery storage. It is designed to provide round-the-clock power without relying on the grid. Solar addresses daytime load, micro wind picks up power generation during the night, and stored energy is used during periods of low generation. This set up is ideal for off-grid or high-tariff scenarios such as fuel stations or industrial units running on diesel generators.
Our project for BPCL’s fuel station includes solar panels, vertical and horizontal axis wind turbines and battery storage, combined with an electric vehicle (EV) charging set up. It is a turnkey solution that can be replicated across India’s over 80,000 fuel stations.
What are the typical cost structures and tariffs involved for the rooftop solar and micro wind segments?
In the rooftop solar space, our clients typically pay between Rs 4.90 per unit and Rs 5.20 per unit under long-term PPAs, which is quite competitive. The systems generally offset 25-30 per cent of their overall power needs. We do not offer micro wind under PPAs currently, as its economics are more suited for direct capex models.
A 1 kW micro wind turbine costs between Rs 95,000 and Rs 120,000, with a payback period of four to five years. While solar systems are more cost-efficient, micro wind proves viable in high-tariff zones or where diesel generators are used, given their cost of Rs 30-Rs 35 per unit. In addition, the integration of micro wind power is more justified where grid access is limited or unreliable.
What was the motivation behind entering the micro wind and tribrid space, and how does it compare with other distributed technologies?
Micro wind remains a largely untapped resource in India. The motivation was both technical and market-driven. Wind turbines generate power at night, balancing solar’s daytime generation. The addition of storage completes the 24×7 energy solution.
The key challenge lies in the integration and synchronisation of these systems. For example, at our BPCL model site, the design ensures that when neither solar nor wind is available, battery systems step in. This seamless integration is technically complex but highly impactful. We see strong potential, especially as industries move towards net-zero targets.
What are the major operational challenges that Revayu has encountered, especially for hybrid and tribrid deployments?
One of the key challenges is integration, bringing together solar, wind, battery and EV infrastructure in a synchronised manner. It is not just about installing components but also managing load flows, forecasting generation and ensuring 24×7 reliability.
For instance, our tribrid project involved vertical axis turbines that leverage not just ambient wind but wind from vehicular traffic. These need clearances from highway authorities like the National Highways Authority of India, and installation techniques are still evolving.
We have previously developed wind solutions for powering telecom towers, where there were several operational constraints due to remote locations and the growing reach of grid power, which slowed adoption. That said, we are considering a revival of this segment.
How do you see Revayu’s expansion unfolding in international markets?
Internationally, we have entered Qatar and Dubai through local partnerships. Qatar, in particular, is opening up with ambitious 2030 targets. Our first pilot is complete, and we aim to execute a 100 MW project over the next year in the region.
How much financing have you raised over the years?
On the funding side, we raised over $1 million in last two to three years. We are now in the process of raising another $10 million for our project pipeline. These funds will help us scale our manufacturing, enter new geographies, and support our EPC and developer projects.
What are your policy suggestions to the government?
Going forward, policy frameworks need to catch up with technological innovations in the renewable energy sector. I have three suggestions. One, the Approved List of Models and Manufacturers (ALMM) drives up costs by 10-20 per cent compared to imported modules. While the intent is to promote domestic manufacturing, it limits flexibility for projects focused purely on captive consumption and off-grid use. Hence, the ALMM policy can be made more flexible for off-grid projects.
Two, the small wind segment needs clear policy support, which is lacking today. Only a few states have net metering provisions for micro wind.
Three, going forward, simplifying approvals, enabling banking provisions where possible and encouraging captive hybrid models through incentives or viability gap funding will accelerate deployment.
