Chhattisgarh Proposes ₹3.40/kWh Solar Tariff for Small Renewable Projects in FY27

The Chhattisgarh State Electricity Regulatory Commission (CSERC) has proposed a generic levelized tariff of ₹3.40 per kWh for solar photovoltaic projects in the 500 kW to 2 MW capacity range, applicable for projects commissioned during FY 2026-27. The regulator has simultaneously proposed ₹4.95 per kWh for biogas-based power projects in the same financial year. Both figures represent a marginal increase over the current FY 2025-26 benchmarks — ₹3.39 per kWh for solar and ₹4.88 per kWh for biogas — reflecting rising project costs even as India's broader utility-scale solar sector continues to discover tariffs well below ₹3 per kWh through competitive SECI auctions. The CSERC proposals are still at the consultation stage and will be open to stakeholder comment before finalisation. For small renewable energy developers, rooftop installers, and rural electrification project sponsors operating in Chhattisgarh, this tariff revision sets the financial floor for project viability in FY27 and carries meaningful implications for how solar energy India's central Indian states develops at the distributed, community scale.

Why Has CSERC Revised the Solar Tariff Upward for FY27?

The ₹3.40/kWh proposed tariff represents a one-paisa-per-kWh increase over the FY26 solar benchmark — a modest revision on paper, but one that CSERC has anchored to updated capital cost assumptions, operation and maintenance norms, and financing cost parameters. Generic levelized tariffs set by state electricity regulatory commissions serve a fundamentally different function from the tariffs discovered through SECI or state-level competitive auctions. They act as administered price signals for smaller developers — typically those building captive, rooftop, or rural solar installations — who cannot participate in large-scale tenders requiring hundreds of megawatts of capacity. In Chhattisgarh's context, where distributed solar deployment remains underpenetrated compared to sun-belt states like Rajasthan and Gujarat, a credible and bankable tariff floor matters enormously. Developers financing projects through rural cooperative banks or NABARD refinancing windows rely on these regulatory benchmarks to demonstrate revenue certainty to lenders. A tariff that keeps pace with input cost inflation — even incrementally — signals that CSERC is tracking market realities rather than artificially suppressing returns.

The biogas tariff revision from ₹4.88 to ₹4.95 per kWh tells a parallel story. Biogas and biomass-based power in central India faces distinct cost pressures: feedstock procurement, storage logistics, and plant operation expenses have all risen over the past 12 months. A ₹0.07/kWh upward adjustment will not transform project economics overnight, but it demonstrates regulatory acknowledgement that non-solar renewable energy India needs differentiated and realistic pricing to attract investment beyond the photovoltaic mainstream.

How Do Chhattisgarh's Tariffs Compare With National Solar Benchmarks?

India's utility-scale solar sector has seen discovered tariffs consistently fall below ₹2.50 per kWh in recent SECI auctions, with some bids from major developers like Adani Green Energy, ReNew Power, and NTPC Renewable Energy dipping even lower on premium sites in Rajasthan's Thar desert or Gujarat's Khavda renewable energy park. Against that backdrop, ₹3.40 per kWh may appear elevated. But the comparison is misleading. Generic tariffs apply to sub-2 MW projects that cannot achieve the economies of scale, dedicated transmission evacuation infrastructure, or land aggregation advantages available to gigawatt-scale parks. A 1 MW solar plant in a semi-urban district of Chhattisgarh — with its smaller procurement volumes, higher per-unit balance-of-system costs, and limited grid interconnection options — has a fundamentally different cost structure from a 500 MW park in Rajasthan backed by a AAA-rated developer with access to green bonds and international equity. CSERC's ₹3.40/kWh benchmark is therefore best read against comparable state-level small-project tariffs across Madhya Pradesh, Odisha, and Jharkhand, where administered rates for sub-5 MW solar installations cluster in the ₹3.20–₹3.60 per kWh range.

For the PM Surya Ghar Muft Bijli Yojana scheme, which targets one crore rooftop solar installations nationally, and for MNRE's broader push to activate distributed solar capacity in Tier 2 and Tier 3 cities, having a functioning generic tariff framework in states like Chhattisgarh is a prerequisite — not a luxury. Without a credible administered rate, smaller project developers simply do not enter the market, and national capacity targets remain disproportionately dependent on a handful of large solar parks in a few states.

What This Means for India's Energy Transition

India's 500 GW renewable energy target by 2030 cannot be achieved through large-scale solar parks alone. The MNRE and SECI pipeline of utility-scale projects, while impressive in aggregate, leaves significant distributed generation potential untapped — particularly in states like Chhattisgarh, which has lagged behind solar-rich states in both installed capacity and private sector developer activity. Generic tariff orders from state regulators are the administrative scaffolding that makes distributed clean energy investment possible. When CSERC finalises its FY27 tariff order — with a ₹3.40/kWh benchmark for solar and ₹4.95/kWh for biogas — it gives project developers, lending institutions, and state DISCOMs a shared reference point for power purchase agreement negotiations. That certainty, even at the margins, is what unlocks the pipeline of 500 kW to 2 MW projects across rural Chhattisgarh that would otherwise remain in limbo.

Watch for CSERC's final tariff order expected before the close of FY 2025-26. Key variables to track include whether the commission adjusts capital cost benchmarks in response to stakeholder submissions, how Chhattisgarh's state DISCOM — CSPDCL — responds to the proposed biogas rate, and whether the MNRE issues updated capital cost norms for small solar that could influence regulators across multiple states simultaneously. EXD will report on the final order as soon as it is issued.
