Resources & guides

Guides on HT connections, LT vs HT, transformers, approvals; FAQs, glossary and downloads.

Which areas do you work in?

We work across Tamil Nadu from our branches, and take up larger projects in neighbouring states.

Are you a licensed electrical contractor?

Yes. Our licence and registration details are shown on the About and Safety & quality pages and on every quote.

What is the maximum load on an LT connection in Tamil Nadu?

LT supply is available up to 150 kW. Above that, an HT connection is needed.

When should I move from LT to HT?

Above 150 kW you must take HT supply. Below that, HT can still save money if you use a lot of energy — try our LT or HT cost comparison tool.

What does an HT connection cost?

You pay TNPDCL charges for the line and metering, and build your own substation (transformer, HT panel, LT panel, earthing). Our HT roadmap tool gives an indicative range.

What is CEIG approval?

The Chief Electrical Inspector to Government approves the drawings of HT installations before work and inspects them before energisation.

How long do approvals take?

Typically several weeks for each stage; our liaison team tracks every stage and shows it in your client portal.

Why is my HT bill so high even when production is low?

Demand charges are billed on the higher of recorded demand or 90% of your contract demand. If your contract demand is too high, you pay for capacity you don't use — try the contract demand optimiser.

How do I avoid the power factor penalty?

Keep your average power factor at 0.90 or above with an APFC panel; with many VFDs or UPS loads, use detuned reactors.

What does an AMC include?

Scheduled preventive maintenance visits with checklists and reports, breakdown response within agreed times, and testing as listed in the contract.

Can you maintain installations done by others?

Yes. We start with a condition survey and then propose an AMC.

Can I add solar to an HT connection?

Yes, within your contract demand and the current TNPDCL rules; we handle the metering application.

How do you keep sites safe?

Every HT and isolation job runs under a permit to work with lock-out / tag-out, an authorised person, and daily toolbox talks. Safety officers can stop any job.

Do you give fixed-price quotes?

Yes, after a site survey we give an itemised techno-commercial proposal with clear inclusions and exclusions.

How do I track my project?

Clients get a portal login with progress, photos, drawings, approvals, bills and documents.
