COLOMBO, June 11 (Xinhua) -- The Public Utilities Commission of Sri Lanka (PUCSL), the country's electricity regulator, has approved a 15 percent increase in electricity tariffs, effective Thursday.

In a statement, the PUCSL said tariffs for electric vehicle charging stations will remain unchanged.

The commission noted that the impact of the tariff revision will vary across user groups. Higher-consuming households and non-domestic users are expected to contribute more significantly to overall revenue.
