The major industrial centers in Maharashtra include Pune, Nagpur, Aurangabad, Nashik and Mumbai which are the major manufacturing sectors in India. These cities are the drivers of industries such as automotive, pharmaceuticals, textiles, engineering and food processing. The current issues of increased electricity tariffs, fluctuating fuel prices and the increasing impact of Time-of-Day (ToD) charges are making industries here quite difficult as profits are narrowed in 2025. To further add to this, untrustworthy supply of power, such as grid unpredictability and volatility, is posing a hindrance to production and supply chain commitments.
In this case, progressive industrial executives are considering energy management as a business strategy rather than an operating cost that is a matter of routine. The shift to solar energy in Maharashtra in relation to the power grid to power industries is no longer a question of sustainability; but, it has become a question of survival of competitiveness. With the support of the development of high-efficiency solar technology, dynamic government policies, and flexible financial framework, industries utilizes solar in maharashtra to reduce its operating expenditure, improve the reliability of its energy supply, and meet both national regulatory and international ESG requirements.
Industries in Maharashtra are increasingly adopting rooftop solar solutions, backed by MERC net metering rules, open access solar policies, tax benefits & accelerated depreciation. The below listed reasons help factories to store more power for future use & boost the ROI.
Maharashtra’s regulatory framework is now more industry-friendly than ever, thanks to progressive updates from the Maharashtra Electricity Regulatory Commission (MERC) and national renewable energy mandates. These changes reduce bureaucratic hurdles and make industrial solar power systems more commercially viable.
MERC has simplified solar rooftop for industries through faster net metering approvals and introduced Virtual Net Metering (VNM) to benefit multi-building industrial complexes or leased facilities. It also allows concurrent use of net metering with open access solar, enabling industries to maximize savings from net metering and open access solar models.
The Green Energy Open Access (GEOA) policy lets industries directly source cheaper electricity from large-scale solar power plants for industry, bypassing DISCOM retail tariffs. Banking provisions with an 8% charge and monthly settlement allow better load management and predictable energy costs.
Industries opting for CAPEX can claim Accelerated Depreciation under the Income Tax Act, significantly improving post-tax IRR. GST offers corporate tax deductions on depreciation further enhance the financial viability of industrial solar power plant installation projects.
Pharma, textiles, engineering & food processing are some of the major industries in Maharashtra now turning to solar power. With electricity rates & Time-of-Day (ToD) charges going high, solar panels helps to reduce production costs. By installing solar panels, these industries can lower power bills, control budgets & reduce carbon emissions.
The pharmaceutical industry in Maharashtra has been one of the earliest and fastest movers toward solar adoption. With manufacturing facilities operating round the clock and requiring stringent climate control for quality and compliance, energy reliability is paramount. Case examples include pharma plants in Aurangabad and Pune that have installed rooftop solar panels for industrial buildings in the 1–2 MW range, achieving up to 60% reduction in grid dependency. By generating clean power on-site, these facilities have significantly lowered production costs while ensuring uninterrupted operations that meet both domestic and export standards.
In the textile sector, processes such as weaving, dyeing, and finishing consume high levels of electricity, particularly during daylight hours. Textile units in industrial hubs like Ichalkaranji have embraced hybrid models combining solar rooftop for industries with open access supply. This has enabled them to offset a large portion of their peak-hour demand, stabilize energy pricing, and reduce exposure to seasonal tariff hikes. The result is a notable drop in per-unit production costs, which improves profitability and supports competitiveness in both local and international markets.
The engineering industry, encompassing fabrication, machining, and heavy equipment manufacturing, has also found strong value in industrial solar power systems. Case studies from Pune’s industrial belt show engineering companies using 5–10 MW open access solar power plants for industry to meet bulk energy needs at tariffs 20–30% lower than grid rates. This consistent and affordable power supply has reduced operational risks, improved cost predictability, and allowed companies to reinvest savings into production efficiency upgrades.
For the FMCG sector, continuous production cycles and energy-intensive cold storage facilities make reliability and cost control critical. FMCG manufacturers in Nashik and Mumbai have adopted hybrid solar panels for industrial units through rooftop and open access setups to guarantee uninterrupted power for refrigeration and processing lines. These systems have reduced dependence on diesel generators, cut exposure to high ToD tariffs, and delivered substantial annual savings. Beyond cost benefits, the switch also supports sustainability targets, which are increasingly important to both retailers and end consumers.
In Maharashtra, the payback period for industrial solar power systems depends on the chosen model. CAPEX projects, where the business owns the system, typically recover costs within three to five years, aided by benefits like Accelerated Depreciation. OPEX or RESCO models require no upfront investment and provide immediate savings through long-term power purchase agreements at fixed tariffs, usually between ₹5.5 and ₹7.0 per kWh.
Real-world cases highlight these advantages. A 1.5 MW solar rooftop for industries installation at a pharmaceutical facility in Aurangabad achieved payback in four years with an LCOE of ₹3.8 per kWh. An 8 MW open access OPEX project for an auto-ancillary plant in Pune secured tariffs of ₹5.5–₹6.5 per kWh, cutting annual energy costs by around 35%.
ROI is influenced by factors such as daytime load profile, system size, available space, and the financing model selected. Policy elements like net metering, open access charges, and banking provisions also play a role, making a detailed feasibility study essential before moving forward.
The year 2025 presents a unique opportunity for industries to adopt solar power, driven by regulatory reforms, falling costs and rapid technology advancements. Companies that act now can secure long-term savings, reliability and sustainability benefits ahead of future market shifts.
In today’s competitive business environment, energy efficiency & sustainability are not just advantages they are essential. With rising electricity costs and growing focus on ESG compliance, commercial and industrial (C&I) businesses are increasingly adopting solar as a long-term solution. GSE Renewables focuses on installing high performance solar power systems for manufacturing facilities, warehouses, office buildings, hospitals and schools. We will provide a complete set of turnkey capabilities including unique system design, whole project execution, punishment from regulatory standards, flexibility in CAPEX/OPEX/RESCO and the ability to manage each asset after installation.
For CAPEX, the payback period is around 3–5 years with accelerated depreciation and ToD savings, while OPEX offers immediate savings without upfront costs.
Yes, industries can benefit from MERC net metering rules, open access banking provisions, and accelerated depreciation under government policies.
Yes, provided the building passes checks for structural strength, load-bearing capacity, and shading conditions.
Typically, rooftop solar requires about 80,000–100,000 sq ft of space per MW installed.
