Karnataka 315 MW Wind Evacuation: Kshema Power Order Details

India’s Karnataka state now hosts close to 8,900 MW of installed wind capacity, making it one of the country’s largest wind markets. In August 2026, domestic transmission contractor Kshema Power secured an order covering the evacuation infrastructure for a 315 MW wind farm in the state, including 220 kV transmission lines, unit substations, and 33 kV distribution networks. The contract highlights the engineering scope, equipment demand, and supply-chain priorities of India’s latest transmission investment cycle.

1. Project Background and Grid Drivers

1.1 Renewable Capacity Expansion in India

According to India’s Ministry of New and Renewable Energy (MNRE), the country added 6,057 MW of wind capacity in FY26, taking total installed wind capacity above 57 GW. Karnataka, with close to 8,900 MW of installed wind, ranks among the top wind markets nationally. At this scale, every incremental megawatt of wind capacity requires corresponding evacuation corridors and grid-connection infrastructure.

1.2 Transmission Constraints in Karnataka

Wind output is inherently variable, and most capacity sits in coastal and plateau regions that are geographically distant from the main load centres. As a result, every new wind farm must be paired with full evacuation infrastructure, including high-voltage export lines, unit step-up substations, and 33 kV collection networks inside the wind farm boundary. For parallel context on India grid expansion, see our analysis of India’s FY27 35.7 GVA substation capacity expansion.

1.3 Scope Definition of the 315 MW Order

Kshema Power’s order covers evacuation infrastructure for a single 315 MW wind farm, sitting at the “wind farm – main grid” interface. Its purpose is to step up and export wind-generated power through a 220 kV line into the backbone grid, while collecting power internally through 33 kV infrastructure inside the farm.

2. Engineering Scope and Key Parameters

2.1 220 kV Transmission Line

The contract covers approximately 33 km of 220 kV single-circuit transmission line, built on double-circuit and multi-circuit towers. This “single-circuit conductors on multi-circuit structures” approach satisfies the current wind farm’s connection requirements while reserving corridors for future expansion, a common engineering strategy for Indian transmission builds.

2.2 Unit Step-up Substation

The project also includes a unit substation that steps up voltage from the wind farm’s 33 kV side to 220 kV. A typical unit substation uses a 220/33 kV two-winding transformer, sized with overload capability to match the variable output profile of wind generation.

2.3 33 kV Collection Network

Inside the wind farm, 33 kV collection lines and supporting infrastructure aggregate output from dispersed turbines into the unit substation. This level is typically built with overhead lines or cables depending on the farm layout and terrain.

3. Macro Drivers: India’s National Electricity Plan (NEP-T)

3.1 191,000 Circuit-Kilometres Target

India’s National Electricity Plan for Transmission (NEP-T) projects more than 191,000 circuit kilometres of new transmission lines and investment exceeding $95.76 B (Rs 9.15 lakh crore) through 2032. The plan covers renewable interconnection, inter-regional links, and load-centre reinforcement.

3.2 Non-Fossil Targets Drive Transmission Investment

India has committed to 500 GW of non-fossil installed capacity by 2030, a target that places systemic pressure on the transmission network. The mismatch between the output curves of wind and solar and the load curve requires denser transmission networks and a more flexible grid dispatch model.

3.3 Investment Tempo and Equipment Demand

Across the planning cycle, India will add more than 25,000 circuit kilometres of transmission lines per year on average, requiring large volumes of power transformers, circuit breakers, overhead conductors, insulators, and protection and control equipment. This provides a stable order flow for global transmission equipment supply chains.

4. Kshema Power’s Recent Project Portfolio

4.1 400 kV Line in Andhra Pradesh

Kshema Power recently secured a 400 kV transmission line project in Andhra Pradesh, extending its capability into higher voltage classes. 400 kV lines are typically deployed for inter-regional connections or large power evacuation, demanding more rigorous tower design, conductor selection, and insulation coordination.

4.2 33/220 kV AIS Substation in Madhya Pradesh

In Madhya Pradesh, Kshema Power secured an order for a 33/220 kV air-insulated substation (AIS). Compared with gas-insulated substations (GIS), AIS offers lower capital cost but requires more land, making it well-suited to inland regions with less land pressure.

4.3 Portfolio Signals Market Trends

From 220 kV evacuation lines to 400 kV inter-regional lines, and from 33/220 kV substations to wind evacuation infrastructure, Kshema Power’s project mix spans multiple layers of renewable evacuation engineering. This reflects the rising activity of Indian domestic contractors in the transmission EPC market.

5. Implications for the Transmission Equipment Supply Chain

5.1 Transformer Demand Mix

220/33 kV unit transformers and 400 kV-and-above inter-regional transformers are central to the current India wind evacuation build. The former is a standard medium-voltage power transformer, while the latter involves higher technical thresholds in high-voltage insulation, partial discharge control, and transport logistics.

5.2 Overhead Conductors and Towers

A 33 km, 220 kV line implies hundreds of transmission towers and hundreds of tonnes of overhead conductor. With double-circuit and multi-circuit structures, the per-tower mechanical load on conductors and earth wires increases significantly, raising the requirements on tower steel, foundation design, and hardware selection.

5.3 Protection and Automation

New wind evacuation builds need integrated protection, metering, control, and communication systems, including line differential protection, busbar protection, auto-reclosing, and PMU-based synchrophasor measurement. These secondary systems are critical for coordinating wind farm behaviour with the main grid.

6. Conclusion

Kshema Power’s 315 MW wind evacuation contract in Karnataka is a microcosm of India’s current transmission expansion cycle. Under the NEP-T framework of 191,000 circuit kilometres and $95.76 B of investment through 2032, similar 220 kV evacuation projects and 33/220 kV substation builds will continue to be released across multiple states. For transmission equipment manufacturers, this market provides steady order flow while demanding full-spectrum product capability across voltage classes, insulation levels, and environmental conditions.
