India's renewable energy journey is not just about policy and potential—it’s about real savings, real results, and real success stories. At the forefront of this transformation are smart corporates who have adopted Third-Party Open Access (OA) Solar Power and are now enjoying tangible benefits—including energy cost savings of ₹1 per unit or more.
Let’s look at how this model is driving value for our clients across India.
Case Study 1: FMCG Giant – Maharashtra
Power Source: Solar (Third-Party OA) | Annual Savings: ₹3.5 Crores | Discom Tariff: ₹8.20/unit
A top-tier FMCG brand shifted 70% of its plant load in Pune to solar power sourced from a developer in Solapur. With fixed OA tariffs around ₹7, savings exceeded ₹1.20 per unit.
Client Feedback:
“We’re not just saving on power bills—we’re saving face in global ESG scorecards. And yes, the ₹3.5 crore annual saving helps too!”
Case Study 2: Textile Major – Tamil Nadu
Power Source: Wind (Third-Party OA) | Annual Savings: ₹2.2 Crores | Units Used: 25 Million | OA Tariff: ₹4.85
This client tapped into Tamil Nadu’s robust wind corridor near Tirunelveli to secure third-party OA power for its dyeing and spinning units.
Client Feedback:
“Wind energy through OA was a no-brainer. We locked in ₹1.10/unit savings, 24x7 supply, and even better grid compliance than expected.”
Case Study 3: Pharma Manufacturer – Gujarat
Power Mix: Wind + Solar OA | Total Savings: ₹1.8 Crores | OA Tariff: ₹5.10 | Discom Tariff: ₹6.30
To ensure round-the-clock green power, this pharma firm combined daytime solar and nighttime wind through hybrid open access, made possible under Gujarat’s policy.
Client Feedback:
“It’s like a renewable buffet—we take solar during the day, wind at night. No more peak demand penalty shocks!”
Case Study 4: IT Campus – Telangana
Power Source: Solar OA | Consumption: 18 Million Units | Savings: ₹0.95/unit
A major IT services company in Hyderabad used OA solar to green its energy profile. Their rooftop was saturated, so they turned to third-party OA developers to meet their CSR and net-zero goals.
Client Feedback:
“We saved ₹1 crore last year—without touching our roof. All backend, billing, and compliance handled by the OA provider.”
Case Study 5: Cement Company – Karnataka
Power Source: Wind OA | Plant Load: 6 MW | Savings: ₹1.35/unit | Total Annual Benefit: ₹5+ Crores
This cement major adopted wind OA from a third-party IPP in Chitradurga. With higher PLF and minimal wheeling charges due to proximity, they locked in massive cost benefits.
Client Feedback:
“Unlike solar, wind gave us high nighttime supply. We now save over ₹5 crores per year with a 10-year PPA—zero capex, all gain.”
