Electricity Connection Charges Calculator

Work out electricity connection charges instantly with clear inputs, formula shown and shareable results.

About Electricity Connection Charges Calculator

Electricity connection charges scale with sanctioned load: a connection charge per kilowatt for network reinforcement, a security deposit per kilowatt against unpaid bills, and the cost of the meter. Only the deposit is refundable, so over-sanctioning load permanently increases the non-refundable outlay and often the fixed monthly demand charge too.

Formula

Connection charges

Total = load x connection rate + load x deposit rate + meter cost

Worked example

With the default values below, Electricity Connection Charges Calculator returns Total payable at application of $53,500.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Preliminary estimate only. Connection charges, deposits and load sanction rules are set by the distribution utility and regulator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Electricity Connection Charges figure worked out?

Total = load x connection rate + load x deposit rate + meter cost. Electricity connection charges scale with sanctioned load: a connection charge per kilowatt for network reinforcement, a security deposit per kilowatt against unpaid bills, and the cost of the meter.

Should I sanction extra load for the future?

Only with care. Extra sanctioned load raises the fixed demand charge every month, so it is usually cheaper to enhance load later than to carry unused capacity for years.

What values do I need to enter?

This calculator takes 4 inputs: Sanctioned load, Connection charge, Security deposit, Meter and accessories. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
