Frequently Asked Questions

Under the Electricity Act 2003, a Captive Generating Plant (CGP) requires the captive consumer to hold at least 26% equity ownership in the generating company and consume a minimum of 51% of generated power annually. This grants 100% exemption from Cross-Subsidy Surcharge (CSS) and Additional Surcharge (AS). In a Group Captive structure, multiple industrial off-takers pool their equity collectively to achieve the 26% threshold, unlocking substantial per-unit cost savings without requiring any single client to finance 100% of the project.

Third-Party Power Sale enables commercial and industrial (C&I) enterprises to procure clean electricity directly from Opera Energy’s utility-scale wind and solar parks via Open Access on state (InSTS) or central (ISTS) transmission grids. Under bilateral long-term Power Purchase Agreements (PPAs), clients achieve immediate tariff reductions and green energy compliance without capital investment.

Under the CAPEX model, the industrial client owns 100% of the renewable generating asset. Opera Energy manages end-to-end Turnkey EPC execution—from revenue land procurement and micrositing to GETCO substation construction and commissioning. This empowers clients to claim accelerated depreciation benefits, direct solar/wind renewable energy certificates (RECs), and achieve the lowest levelized cost of energy (LCOE) across the plant’s 25-year lifetime.

Yes. Beyond turnkey EPC services, Opera Energy develops, finances, constructs, owns, and operates utility-scale renewable energy assets as an Independent Power Producer (IPP), supplying reliable green power directly to state discoms (like GUVNL, SECI) and leading multinational industrial corporations.

Our 360-degree turnkey EPC scope covers resource measurement & wind mast installation, revenue land acquisition, environmental & statutory approvals, geotechnical investigations, foundation engineering, WTG & solar PV array erection, 33/66/220 kV high-voltage pooling substation design & commissioning, transmission line stringing, GETCO grid synchronization, and lifetime SCADA-monitored Operations & Maintenance (O&M).

A typical utility-scale turnkey wind or hybrid project takes between 12 to 18 months from initial land demarcation to full grid synchronization. Key milestone durations include 4-6 months for statutory land clearances and connectivity approvals, 6-8 months for civil foundations and electrical balance of plant (BOP), followed by final turbine erection, cold commissioning, and grid synchronization.

Opera Energy has in-house electrical EPC capabilities to construct 33 kV, 66 kV, 132 kV, and 220 kV AIS/GIS pooling substations. We engineer power transformer bays, SF6 breaker switchgear, automated SCADA monitoring control rooms, and dedicated double-circuit transmission lines compliant with CEA and STU technical grid codes.

Wind-Solar Hybrid projects leverage complementary diurnal generation patterns—solar peaks during peak daylight hours while wind generation predominantly surges during late afternoons, evenings, and night hours. This maximizes evacuation infrastructure utilization, significantly raises the capacity utilization factor (CUF up to 45–55%), reduces grid transmission losses, and provides round-the-clock power stability.

We partner exclusively with Tier-1 global OEMs, installing high-efficiency class-III WTGs with hub heights exceeding 120m–160m and 3.0 MW+ nameplate capacities. For solar installations, we employ high-efficiency N-type TOPCon and bifacial mono PERC modules coupled with automated single-axis solar tracking systems for maximum energy yield.

Opera Energy delivers utility-scale containerized BESS solutions (such as our 15 MW / 60 MWh system for NHPC in Kerala) using liquid-cooled Lithium Iron Phosphate (LFP) chemistry for peak shaving, spinning reserve, and frequency stabilization. Additionally, we are actively advancing Green Hydrogen electrolyzer integration with dedicated hybrid parks and marine wave/tidal hydrodynamic research along the Gujarat coastline.
