Maharashtra HT demand charge rise pushes
Rising HT demand charges and evolving solar rebates in Maharashtra are forcing commercial and industrial businesses to adopt integrated energy strategies
Commercial and industrial businesses in Maharashtra must adopt layered energy strategies as HT demand charges rise and solar rebates evolve. Most Indian businesses do not have a single energy strategy, instead making isolated energy decisions over time which leads to suboptimal outcomes.
Energy strategy should be built in layers. Layer One requires one year of interval consumption data broken down by time-of-day, season, and shift.
Maharashtra-specific tariff and incentive mechanics
In Maharashtra, solar credits earned during 09:00-17:00 can only be redeemed in that window, a system known as slot-wise banking. A Grid Support Charge applies to net-metering consumers above 10 kW. The state's HT demand charges are rising from ₹600 to ₹750 per kVA per month, making annual demand audits worthwhile for businesses.
Flexible loads should be shifted to the daytime window to leverage time-of-use benefits. This includes batch processes, HVAC pre-cooling, water pumping, and EV charging. Rebates for this daytime consumption are currently 15% from April to September and 25% from October to March. These incentives are set to increase to 20% and 30% respectively from the financial year 2027-28.
Cost reduction and solar optimisation tactics
Improving power factor can reduce costs for HT consumers in Maharashtra who are billed on kVAh. Businesses are advised to maximise rooftop solar first to avoid wheeling, transmission, and cross-subsidy charges. For new renewable projects above 100 kW in Maharashtra, storage of at least 50% of project capacity for two hours is a connectivity requirement. This storage mandate increases to four hours for projects commissioned from FY 2030-31.
Storage should be sized against a business's actual load profile, with the regulatory minimum as a starting point. Businesses can consider various commercial structures for solar and storage, including capex ownership, operating leases, storage-as-a-service, or group captive models. Ownership offers higher lifetime returns and accelerated depreciation but carries technology risk. Service models reduce upfront investment and transfer performance risk, though returns may be lower. Solar and storage investments do not need to follow the same commercial structure.
Market context and strategic actions
India added close to 6 GW of solar open-access capacity in the first half of 2026, a 42% year-on-year increase. Karnataka, Rajasthan, and Maharashtra are the leading states in this capacity addition. Businesses should evaluate the landed cost of open access, which includes wheeling, cross-subsidy, surcharge, banking, and scheduling charges. Green tariffs and round-the-clock renewable contracts from distribution companies are also emerging as options for securing clean power without owning generation assets.
A named person within a company should own energy costs across both procurement and operations. Businesses are urged to review their contracted demand annually and re-model their portfolio when tariffs or policies change. Maharashtra has published HT tariff trajectories through FY 2029-30. Commercial and industrial renewable capacity in India is projected to rise from 32 GW in 2025 to 100 GW by 2032. Corresponding storage is projected to grow more than tenfold to 31 GWh by 2032.
Businesses building energy strategy now will be better positioned to manage costs, optimise investments, and secure capacity before market crowding.
