National gas grid usage fees go up 29%: The Gas Regulatory Authority has raised usage fees for the national gas grid 29% to USD 0.375 per mmbtu, according to a statement picked up by Reuters. The previous usage fees of USD 0.29 per mmbtu were set in December, which marked a 24% decrease from the earlier price set in August 2018 that stood at USD 0.38 per mmbtu. The hike is a step towards the “gradual liberalization of the market,” the regulator said.
