Neptunus Power


We deliver end-to-end turnkey EPC projects (MEP, HVAC) through reliable design engineering of operator-friendly DG-based backup power plants for Data Centres, Industrial CCPs, Oil Rigs, and Engines Test Cells.


Designs That Work

Design engineering
Our vision for new-age design engineering

At Neptunus, we leverage our insights from over 23 years of experience with diesel and gas engines of various makes and capacities and their applications in data centers, industrial, commercial, marine and oil & gas projects.

We strongly believe in a cost-efficient, environmentally prudent and smarter way to maintain large machinery by combining design engineering with new-age technology to deliver optimized designs that save money, maximizes uptime and OHS compliance

engineering solutions
End to End Engineering Solutions

We have studied engines, machines and DG-sets for over 2 decades, and this has enabled us to be end-to-end design engineering solution providers. From procurement, construction and commissioning of engine-based back-up power plants to MEP, HVAC and designing fire systems for industrial and commercial facilities, Neptunus has in-house certified experts for all things engines. Our Project Management capabilities would ensure we deliver complex engineering projects within agreed timelines, costs and quality to ensure QVC(Quality-Velocity-Cost) always!

market Track Record
Market Track Record

We work in the Marine, Oil and Gas, Industrial and Defence Sectors and have completed over 45 mid-sized greenfield and brownfield projects over the past 10 years across the Middle East, Africa and India. Our track record has been built across a diverse range of projects ranging from shifting and refurbishing power plants and designing pack-up power systems for a 41 MW Data Centre to designing engine room ventilation systems and repowering a 20-ton engine on an offshore platform for one of the world’s leading Oil and Gas companies.

Our Value Addition

Increasing Operational Life

  • Operator friendly design layout of critical machinery such as generators
  • Lowering operating risk by foreseeing future maintenance needs (eg: removing radiators from generators)
Increasing Operational Life
Smart Procurement

  • 23 years of working experience across DG-sets of various make
  • Designing Tender Specs, BoQ, and techno-commercial evaluation of supplier bids
  • Robust negotiations resulting in cost savings of upwards of INR 6-9 crore in high side and low-side package of DG.
Smart Procurement
Design Opitmization Pic

  • Lowering the safety hazard of fuel leakage and risk of downtime
  • Designing fire safety features: fusible link which melts in the event of a fire and transfers entire diesel to storage
  • Isolation of fuel supply lines for individual DGs
Design Optimization

  • Lowering the compliance risk and enhancing the safety and productivity.
  • Limiting the “noise” levels due to engine operations within 45 dba max in rooms.
  • Noise attenuation with adding noise silencer in the exhaust air duct.
Health and Safety Compliance
Fuel Management Box Pic

  • Designing a ‘fuel polishing system’ at  fuel intake point of storage tanks to minimize fuel contamination 
  • Lower operational costs and increased engine efficiency by avoiding frequent cleaning of sedimentation in the tank
Fuel Management

Our Key Projects

Project Management and Commissioning of a 41MW backup power plant for Greenfield Data Centre

A practical, operator-centric approach to design the DG backup power plant for Data Center Project led to the saving of more than 2 million USD, enhanced operational efficiency & reduced risks. Neptunus was responsible for the DG room design, ventilation system and tender specifications formation for the Gensets. Neptunus successfully completed the project to adhere to Tier 3 Uptime norms.

Building the world’s first multi-engine, multi-brand engine dyno test cell for Kenyan Navy

Neptunus successfully designed a 4100 KW dyno based test cell for testing naval engines for the Kenyan Navy. Neptunus was contracted for MEP, Structural foundations, engine room ventilation, engine control system with PLC & SCADA, Room acoustic, Fuel automation system, CCTV and FDS, Fire hydrant system, engine & dynamometer cooling system, Air and lube oil system and Utility controls.

Building a 40 MW IPP with diesel-powered engines at Aden - Yemen

Overhauling 3 gas engines and converting them into diesel engines to salvage an aborted project by a previous supplier. The engines were overhauled, commissioned and tested despite severe constraints as a result of operating in a war-torn zone. The end-user- a Yemen conglomerate was thankful to Neptunus for salvaging a USD 5 million investment within a short time period
