Reducing Energy Costs Through Solar-Led Optimisation

Industrial Manufacturing | ₹450+ Cr Enterprise

Context

A mid-sized industrial enterprise with significant energy consumption was facing rising electricity costs and inconsistent grid reliability, impacting operating margins and long-term cost predictability.

Energy had become a structural pressure point on profitability.

The Challenge

The client’s power costs were increasing faster than revenue, with limited visibility on long-term cost stability.

Key constraints included:

High grid tariffs (₹8.2–₹9.4 per unit) and peak demand charges
Annual energy cost inflation of 8–11%
Dependence on diesel generators during outages
Absence of a structured renewable energy strategy
Underutilised rooftop and land capacity for solar deployment

The leadership question was clear:

Create a cost-stable, scalable energy solution without disrupting operations.

The FairNorth Approach

FairNorth conducted a detailed technical, financial, and regulatory assessment to design a solar-led energy optimisation strategy aligned to load profile, ROI expectations, and operational constraints. 

1. Solar Deployment & Energy Structuring

Installation of a 1.8 MW hybrid solar plant (rooftop + ground-mounted)
Designed to align with daytime industrial load patterns
Covered ~30% of total energy demand
Integrated monitoring systems for performance tracking

2. Load Optimisation & Cost Efficiency

Peak load management to reduce demand charges
Significant reduction in diesel generator dependency (~45%)
Alignment of solar generation with consumption cycles

3. Financial & Regulatory Structuring

CAPEX ownership model with tax and depreciation benefits
Access to green financing at preferential rates
Net-metering and regulatory optimisation
ESG and carbon accounting integration

The Outcome (Within 10 Months of Implementation)

Energy Cost Reduction: 

18–22%

Annual Savings:

~₹1.7 Cr

Grid Dependency: 

Reduced by ~29%

Peak Demand Charges:

Reduced by 12%

Diesel Usage:

Reduced by ~45%

Solar plant performance ratio (PR):

79–82%

Zero operational disruption

during integration 

Environmental and Long-term Strategic Impact

Long-term protection against energy price inflation
Improved operational reliability and reduced disruption risk
Strengthened ESG positioning and sustainability reporting with CO₂ reduction ~2,400 tons/year
Enhanced credibility with lenders and customers

Client Testimonial
