Maharashtra’s key industrial hubs Pune, Nagpur, Aurangabad, Nashik and Mumbai play a central role in India’s manufacturing economy. These cities drive sectors like automotive, pharmaceuticals, textiles, engineering and food processing. In 2025, industries here are facing challenges such as rising electricity tariffs, unstable fuel prices, and the growing effect of Time-of-Day (ToD) charges, all of which are squeezing profit margins. On top of this, unreliable power supply, including grid instability and voltage fluctuations, is disrupting production and affecting supply chain commitments.
In this situation, forward-looking industrial leaders are treating energy management as a core business strategy instead of just a routine operating cost. The transition from conventional grid dependency to solar power for industries is no longer driven solely by sustainability goals; it is now a competitive imperative. Supported by advancements in high-efficiency solar technology, progressive government policies and flexible financing structures, a solar power plant for industry in Maharashtra provides a commercially viable pathway to lower operating costs, enhance energy reliability, and ensure compliance with both domestic regulatory frameworks and international ESG standards. This shift not only strengthens business resilience but also positions companies to meet future market and stakeholder expectations with confidence.
Industries in Maharashtra are increasingly adopting rooftop solar panels, backed by MERC net metering rules, open access solar policies, tax benefits & accelerated depreciation. These government incentives help factories lower electricity costs, secure reliable power & achieve better 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, enabling industries to maximize savings from net metering and open access 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 benefits and corporate tax deductions on depreciation further enhance the financial viability of industrial solar panel 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 and 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 has a mission that focuses on executing high-performing solar systems, starting at 150 kW capacity that is well suited for manufacturing facilities, warehouses, office buildings, hospitals and schools.
