Ceylon Electricity Board time of use tariffs
Sri Lankan utility Ceylon Electricity Board has introduced three tariff blocks in a bid to better manage demand and incentivise EV owners to charge their cars during off-peak hours

In South Asia, Sri Lanka's energy regulator has approved a time-of-use tariff proposal submitted by the Ceylon Electricity Board, the largest electricity supplier in the country.

The Public Utilities Commission has given the green light to an optional tariff for domestic users who consume 3-phase, 30 A or above power supply, reports local media The Island.

The tariff will come into effect immediately and consist of three separate time blocks -  off peak (2230-0530), day (0530-1830) and peak (1830-2230), which will be separately metered and billed.

Ceylon Electricity Board will charge 13 Rupees per kWh during off-peak hours, 25 Rupees during day hours and 54 Rupees during peak hours.

The utility said the new tariff structure should encourage consumers to use electricity during off-peak times for the purpose of charging electric vehicles.

In a bid to ease congestion and car emissions, Sri Lanka offers a low rate of tax on electric vehicles.

Last week, BMW Asia finalised a deal with an importer for its BMW i - the BMW sub-brand for its electric cars comprising the all-electric BMW i3 and BMW i8 plug-in hybrid sports car.

The distributor expects to begin retailing the cars in Sri Lanka from later this year.

Sri Lanka smart meters

Meanwhile, customers who sign up to the TOU tariff scheme will have to pay for their own electricity meter.

The metering landscape in Sri Lanka is changing with the launch this year of a domestically-made module.

Residential solar power company JLanka Technologies brought the Pro1000 to market in May 2015.

The smart meter device is targeted at domestic and commercial users and claims to be Sri Lanka's first Internet of Things technology, said Nalin Karunasinghe, consultant for research and development at Jlanka Technologies.

Mr Karunasinghe said the new meters "provide the platform for time of use tariffs and smart grid concept.”

Customers can monitor consumption data through a web-based portal.
