Six Services.
One Team You Can Call.
Power lines, facility upkeep, solar rooftops, breakdown calls at 2am. Most companies pick one of these and stick to it. ADECO Energy has built its business around doing all of them well, for factories, offices, and public infrastructure across India.
A Portfolio Built From Actual Projects,
Not a Wish List
Over 25 years, ADECO has moved from small electrical contracts to full transmission and infrastructure delivery. None of the six services below were added for the sake of a longer list. Each one grew out of client demand for something we were already doing well elsewhere in a project.
Power Transmission Projects
Line and substation construction up to 400 kV.
Integrated Facility Management
Day to day electrical and technical upkeep for working sites.
Operation and Maintenance / AMC
Contracts that keep equipment running instead of just fixing it after it fails.
Refurbishment and Modernisation
Bringing older infrastructure up to current standards without a full rebuild.
Material Supply
Sourcing electrical components that actually match the drawings.
Green Energy Solutions
Solar EPC, energy audits, and the planning that sits behind both.
01
Power Transmission and EHV Turnkey Projects
in power transmission and electrical infrastructure
Power Transmission and EHV Turnkey Projects
A transmission line is only useful if it stays up and stays compliant for decades. That’s the standard we design to. ADECO handles the full sequence, from route survey through to energisation, on lines and substations up to 400 kV.
Before anything gets built
Route surveys, load calculations, and project planning happen first. It's not the exciting part of the job, but skipping it is where most transmission projects run into trouble later.
Construction
Monopole and lattice tower work, line diversion and rerouting, and underground cable runs, built to the voltage class the project calls for, up to 400 kV.
Testing and energisation
Nothing goes live without going through structured testing and commissioning first, run by people who have done this before.
Paperwork that holds up
As built drawings, test records, and the statutory documentation utilities actually ask for, handed over with the project rather than chased down afterward.
Integrated Facility Management
A facility runs on dozens of small systems that only get noticed when they stop working. We manage the electrical and technical side of that so your team can focus on running the business, not chasing maintenance tickets.
Hard FM
Electrical, mechanical, plumbing, fire suppression and HVAC systems — maintained and optimised on a scheduled and as-needed basis.
Soft FM
Housekeeping, landscaping, pest control, waste management and concierge services integrated into a single service contract.
Predictive Diagnostics
IoT-enabled monitoring of critical systems with early fault detection to prevent downtime before it happens.
Performance Reporting
Monthly SLA-linked reports covering uptime, response times, work orders closed and energy consumption trends.
03
Operation & Maintenance / AMC
Full lifecycle accountability for your electrical assets — from scheduled visits to emergency response.
Operation &
Maintenance
/ AMC
An AMC is only worth signing if someone actually shows up when something breaks. Our contracts are built around your specific equipment, not a template, and cover both the routine visits and the calls nobody plans for.
Scheduled work
Inspections and servicing on a set calendar, logged and tracked so there is a record of what was done and when.
When something goes wrong
Breakdown response from technicians who know the equipment, not a call centre reading off a script.
People on site
Dedicated staff assigned to your location, backed by ADECO's broader engineering team when a job needs more hands.
What you actually see
Regular updates on completed work, what's coming up, and where there's room to do things better.
Refurbishment and Modernisation
Replacing an entire electrical system is expensive and disruptive, and it’s often not necessary. ADECO upgrades what’s already there, switchgear, panels, cabling, so it meets current standards without shutting the site down for months.
Switchgear & Panel Modernisation
Replacement or refurbishment of ageing ACBs, VCBs, MCCBs and protection relays to current IS/IEC specifications.
Transformer Servicing & Rebuild
Oil filtration, winding repair, bushing replacement and insulation restoration to extend transformer service life by 10–15 years.
SCADA & Automation Retrofit
Upgrading legacy manual control systems to modern SCADA/RTU platforms for remote monitoring and automated protection.
Post-Work Compliance Certification
Full documentation and third-party testing for CEA, utility board and statutory compliance after every refurbishment.
04
Refurbishment Contracting
Bringing ageing electrical infrastructure back to current standards without full replacement disruption.
05
Material Supply
Certified electrical components delivered to spec, on time — so your project doesn’t wait on parts.
Material Supply
Wrong specification, late delivery, a component that looks right but isn’t. Material supply is a small line item until it holds up an entire project. We source from approved manufacturers and check every order against the actual project drawings before it ships.
Where it comes from
Established manufacturers and suppliers we already work with on our own projects, not a one off sourcing exercise.
What we check
Materials are matched against project drawings before delivery, so you're not finding out about a mismatch on site.
Getting it there
Delivery timed to your construction schedule, so parts show up when the site needs them, not weeks early or a week late.
Competitive Pricing
Volume purchasing relationships with key manufacturers allow us to offer competitive pricing without compromising on quality or certification.
Green Energy
Solutions
Solar makes financial sense for most industrial and commercial sites now, not just an ESG checkbox. ADECO Green Energy handles the full path from site assessment to a working, monitored system, drawing on the same electrical infrastructure experience behind our transmission work.
EPC delivery
Site assessment, system design, procurement, installation, and commissioning, handled as one contract rather than passed between vendors.
HT/LT integration
Transformer integration, grid synchronisation, and metering, built on ADECO's existing electrical infrastructure expertise rather than treated as a separate skill set.
Keeping it running
Preventive maintenance, performance monitoring, and panel cleaning, because a solar system that isn't maintained loses output quietly, without anyone noticing for months.
Project scale
ADECO Green Energy takes on projects from 100 kW up to 10 MW, across industrial, commercial, institutional, and residential sites.
06
Green Energy Solutions
Practical pathways to cleaner energy — solar installations, audits and sustainability planning.
How a Project Actually Moves From
Enquiry to Handover
This is the same four stage process behind every service on this page, whether it’s a transmission contract or a single maintenance visit.
Understand
A site visit and honest technical assessment before we write a single line of a proposal.
Plan
Engineering, scheduling, and resourcing agreed and locked before work starts, not figured out as we go.
Execute
Experienced teams on site, working to safety procedures, with progress checked against the milestones we agreed at the planning stage.
Hand Over
Testing, commissioning, and documentation, followed by your sign off. Until you're satisfied, we don't consider it closed.
Voltage Range and
Equipment Coverage
Our teams work across the full electrical spectrum, from low voltage building systems up to extra high voltage transmission infrastructure at 400 kV.
