Project Overview
AARAA Infrastructure Pvt Ltd is executing civil infrastructure for Continuum Green Energy Ltd.'s 132.26 MW Wind-Solar Hybrid Project at Kudligi, Karnataka. This hybrid project combines wind and solar generation for optimised power output and grid stability. Continuum Green Energy is a leading independent power producer (IPP) in India with a strong renewable portfolio. AARAA's civil infrastructure scope covers the full breadth of site development works needed to enable both wind turbine installation and solar panel mounting across the expansive Kudligi site. The project stands as one of the more complex renewable infrastructure engagements in AARAA's portfolio, requiring simultaneous management of diverse civil engineering disciplines — deep foundation piling for wind turbines, graded road networks, cable trenching, and solar MMS foundations — all executed in parallel across the 132 MW capacity site.
Scope of Work
The civil infrastructure scope for the Kudligi project includes: Site grading and earthworks; deep piling works for wind turbine foundations (requiring drill rigs and specialised boring equipment); AC and DC cable trench excavation, backfilling and compaction; internal access roads with gravel surfacing; drainage channels; reinforced concrete foundations and pedestals for MMS structures and HT/LT electrical equipment; perimeter boundary development; and ancillary civil works. The unique complexity of a hybrid project is that wind turbine foundations require deep pile drilling — often 15–20 metres — through what may be bedrock or hard laterite, while solar MMS foundations are relatively shallow spread footings poured at grid spacing across the entire site. Managing two distinct engineering crews, different equipment fleets, and separate quality control regimes simultaneously on one site demands exceptional project management. AARAA's site team achieves this through daily zone-based work planning, dedicated crew leads for wind and solar civil streams, and a unified digital progress tracking system.
"A hybrid project demands two engineering mindsets on the same site"— the precision of deep pile drilling for wind foundations alongside the grid-scale coordination of solar MMS installation." — AARAA Project Director
Understanding Hybrid Energy Infrastructure
Wind-solar hybrid projects are more efficient than standalone plants because wind and solar generation profiles are complementary — solar peaks during midday while wind generation is often stronger at dawn, dusk, and night. This complementarity reduces grid intermittency and improves plant load factor (PLF) — the ratio of actual generation to installed capacity. India's Ministry of New and Renewable Energy (MNRE) has issued a dedicated Hybrid Energy Policy to promote such projects, recognising that hybrids achieve better grid integration, reduce storage requirements, and lower the levelised cost of energy (LCOE). For Karnataka — which has substantial wind corridors in its northern Deccan districts including Kudligi — the combination of solar and wind generation at a single site also reduces land use, transmission infrastructure costs, and grid interconnection complexity.
Terrain & Execution Challenges
Karnataka's rocky Deccan terrain at Kudligi presented significant drilling challenges. The presence of basalt and hard laterite rock formations required diamond-tipped percussion drilling equipment for wind turbine piling — a significantly more time-intensive and cost-sensitive operation than standard soft-ground piling. AARAA's team mobilised specialist piling rigs and worked in close coordination with geotechnical assessors to adapt foundation designs in real time as sub-surface conditions varied across the site. Managing two separate construction crews — a piling and civil crew for wind infrastructure and a solar MMS civil crew — required meticulous resource scheduling and daily coordination meetings to prevent equipment conflicts and maintain schedule.
Project Significance
The 132 MW Kudligi hybrid project reinforces Continuum Green Energy's growing portfolio of renewable assets in India and contributes significantly to Karnataka's ambitious renewable energy targets. Karnataka has set a target of 10,000 MW of new renewable capacity addition by 2030, and utility-scale hybrid projects like Kudligi play a pivotal role in meeting that goal. AARAA Infrastructure's involvement in this landmark project demonstrates our growing capability in complex, multi-discipline renewable energy civil works — a sector that will only grow as India accelerates its clean energy transition.
