Upgraded Naval Gun & 5 MW Solar Plant at BHEL Haridwar: Boost to Aatmanirbhar Defence and Industrial Decarbonisation
Introduction: Defence Indigenisation Meets Green Manufacturing
On 16 March 2026, Bharat Heavy Electricals Limited (BHEL) Haridwar marked a major milestone by combining defence indigenisation with clean energy adoption.
The unit flagged off an upgraded Super Rapid Gun Mount (SRGM) for the Indian Navy and dedicated a 5 MW ground-mounted solar power plant, reinforcing India’s Aatmanirbhar Bharat and Net Zero 2070 commitments in a single stroke.
Union Minister for Heavy Industries and Steel H.D. Kumaraswamy highlighted that these projects strengthen domestic naval capabilities while reducing industrial carbon footprints, making the manufacturing of strategic equipment cleaner and more self-reliant.
Upgraded Super Rapid Gun Mount (SRGM): Aatmanirbhar Naval Firepower
Role and Background
The Super Rapid Gun Mount (SRGM) is a 76mm medium-calibre naval gun, originally based on the Italian Oto Melara 76/62 Super Rapid, used for anti-aircraft and anti-surface warfare on most frontline Indian Navy warships.
It serves as a point-defence weapon against incoming missiles, aircraft, and fast attack craft, capable of multiple engagements in multi-threat scenarios.
India’s Ministry of Defence signed a contract with BHEL Haridwar in November 2023 to procure 16 upgraded SRGMs under the Buy (Indian) category, worth about ₹2,956.89 crore.
The piece flagged off in March 2026 is identified as around the 53rd upgraded SRGM produced by BHEL Haridwar, reflecting mature indigenous capability.
Key Technical Features
According to BHEL and MoD releases, the upgraded SRGM offers:
- Calibre: 76 mm, 62-calibre barrel (~4.7 m length).
- Rate of Fire: Up to 120 rounds per minute (Super Rapid mode).
- Range: Up to 35 km with suitable ammunition; effective shorter ranges for anti-missile roles.
- Engagement Profile:
- Anti-aircraft (aircraft, UAVs, cruise missiles).
- Anti-surface (fast attack craft, patrol boats).
- Limited shore bombardment.
- Automation: Enhanced automated firing systems, improved fire-control integration, and higher accuracy and reaction speed compared to earlier iterations.
The system interfaces with ship-borne combat management systems, fire-control radars, and electro-optical directors, enabling rapid, computer-controlled engagements in cluttered threat environments.
Strategic Significance
- Reduced Foreign Dependence: Earlier, the Navy relied heavily on Italy’s Oto Melara/Leonardo for the original guns and spares. Local manufacturing and upgrades by BHEL Haridwar reduce vulnerability to foreign export controls and sanctions risks.
- Supply Chain Security: Indigenous production ensures assured lifecycle support, upgrades, and ammunition adaptation without foreign approvals.
- Capability Upgradation: Supports modern doctrines focusing on multi-layered air defence and littoral operations, complementing missiles and CIWS systems.
For UPSC GS Paper III (Indigenisation of Technology & Defence), this is a classic example of transitioning from licensed production to full domestic upgradation and integration.
5 MW Solar Power Plant: Greening Heavy Industry
Project Overview
At the same Haridwar complex, BHEL commissioned a 5 MW ground-mounted solar power plant, dedicated by Minister Kumaraswamy as part of BHEL’s internal clean energy transition.
Key details:
- Capacity: 5 MW (captive).
- Modules: Over 11,000 solar PV modules installed.
- Expected Generation: Around 90 lakh kWh (9 million units) of electricity annually.
- Usage: Integrated into BHEL’s internal grid to power heavy machinery (turbine, generator, naval gun manufacturing, foundry operations).
Environmental and Economic Impact
- Carbon Emissions Reduction: The plant is projected to cut thousands of tonnes of CO₂ emissions annually over its lifecycle, supporting India’s Net Zero by 2070 target.
- Cost Savings: Replacing grid/diesel-based power for part of the load will generate significant operational savings over the medium term, improving BHEL’s cost competitiveness.
- Industrial Decarbonisation: Demonstrates how heavy manufacturing PSUs can become prosumers (producers + consumers) of renewable energy, a key theme in GS Paper III (Energy & Environment).
By powering the manufacture of defence and power-sector equipment with solar energy, BHEL exemplifies the idea of “green defence manufacturing.”
BHEL Haridwar: A Strategic Industrial Hub
The Haridwar facility houses both the Heavy Electrical Equipment Plant (HEEP) and the Central Foundry & Forge Plant (CFFP).
- HEEP: Produces turbines and generators for thermal and hydro power stations, and now high-value strategic equipment like the SRGM.
- CFFP: Supplies large castings and forgings for power, infrastructure, and defence sectors.
Minister Kumaraswamy also inaugurated a 30-tonne Electric Arc Furnace and flagged off a large turbo generator from the facility, underlining BHEL’s role as a core pillar of India’s heavy industrial ecosystem.
UPSC Relevance: Linking Defence, Energy, and Governance
GS Paper III – Indigenisation of Technology
- From Licensed Production to Indigenous Upgrade: BHEL’s upgraded SRGM moves beyond assembling foreign designs to independent upgrade, integration, and lifecycle support.
- Strategic Autonomy: Reducing reliance on Italian OEMs boosts sovereign control over naval capabilities.
GS Paper III – Energy & Environment
- Industrial Decarbonisation: Captive solar plants in heavy industry illustrate how large PSUs can decarbonise operations while maintaining productivity.
- Net Zero Roadmap: BHEL’s initiative aligns with India’s long-term climate commitments.
GS Paper II – Governance & PSUs
- PSU–Armed Forces Synergy: Collaboration between BHEL, the Ministry of Defence, and the Indian Navy reflects how PSUs act as strategic assets rather than mere commercial entities.
- Aatmanirbhar Bharat: These projects operationalise policy slogans through concrete manufacturing and infrastructure outcomes.
