Prepaid Electricity Metering
Prepaid Power — Simpler. Smarter. More Control.
Take control of electricity consumption, simplify revenue collection and eliminate billing inefficiencies with Prow’s intelligent prepaid metering solutions.
Customers buy credit before they use it and top up with a secure 20-digit STS token. There are no estimated bills, no chasing arrears and no disconnection visits — supply simply follows the credit on the meter.
How it works
- 1
Buy credit
The customer pays through your chosen vending channel and receives a 20-digit STS token.
- 2
Enter the token
The token is entered on the meter keypad or on an indoor customer interface unit (CIU).
- 3
Use power
The meter adds the credit, shows the balance and warns the customer before credit runs low.
- 4
Stay in control
At zero credit the relay disconnects automatically; emergency credit can bridge short gaps.

Frequently asked questions
What is an STS token?
STS (Standard Transfer Specification) is the international standard for prepaid meter tokens. Each token is a unique, encrypted 20-digit number that only works on the meter it was generated for.
What happens when credit runs out?
The meter warns the customer as credit gets low. At zero it disconnects supply automatically; emergency or friendly credit can be configured to bridge short gaps.
Should I choose a keypad meter or a split meter?
Keypad (monobloc) meters suit single premises. Split meters keep the meter in a secure meter room while customers top up on an indoor unit — ideal for apartments, estates and hostels.
Can prepaid meters be read remotely?
Yes. Meters such as the PRW-SP-150 accept plug-in PLC, RF or 4G modules for remote reading and management.
