Solar Grid Charges Will Discourage Shift To Cleaner Energy, Say Experts

New fees on rooftop solar energy in Maharashtra, India, are raising concerns among experts. The Maharashtra Electricity Regulatory Commission (MERC) has approved grid support charges on rooftop solar projects bigger than 10 kilowatts (kW). The fees start at ₹1.96 per unit in 2026-27 and rise to ₹2.32 per unit by 2029-30.

Maharashtra’s electricity regulator has approved new grid support charges on rooftop solar systems larger than 10 kilowatts.

The charges apply to power generated during solar hours, even if the owner uses it themselves. MERC introduced the fees after the MSEDCL supply area hit 5,000 MW of rooftop solar capacity in February. The utility says the charges help maintain grid infrastructure, manage surplus solar power, and keep the grid balanced.

Experts and activists warn the fees could hinder clean energy adoption. Large residential complexes, which often install solar systems over 10 kW, may be affected by the new rules. A typical 40 kW solar project may cost around ₹30-35 lakh, with added charges potentially extending payback by several years. This could pose a financial challenge for housing societies considering solar.

Critics also question whether the utility’s cost-shift argument holds up. Studies from Nevada, Mississippi, and Maine found no evidence that solar owners shift costs onto non-solar customers. In fact, rooftop solar provides benefits to the broader grid. It generates power during high-demand periods, which can help avoid expensive electricity purchases. It also reduces wear and tear on grid infrastructure through on-site generation.

In the United States, similar arguments have played out. Monopoly utilities there have lobbied to raise fixed charges and weaken net metering programs. The Edison Electric Institute introduced the cost-shift claim, and it’s persisted despite little supporting evidence. Some analyses point to growing demand, infrastructure upgrades, and other factors as key drivers of rising costs. In California, debates over net metering cuts like NEM 3.0 highlight tensions between utilities and solar adoption. The U.S. solar sector relies heavily on imported components, often from China, exposing it to tariff-related cost pressures.

Back in Maharashtra, activists say the charges threaten residential solar projects and could slow the country’s clean energy shift. The MERC order was issued on March 25, 2026, following a proposal submitted by Maharashtra State Electricity Distribution Company Ltd. Rooftop solar can still cut bills, though new fees may reduce those savings.
