STATE-OWNED electricity transmission business Transend has posted a $47.8million profit for 2012-13 with a surge in energy exports to the mainland contributing to a record year.
The result is up slightly on its previous year's $43 million profit and will inject more than $25 million into the state government's coffers.
Transend chief executive officer Peter Clark said the company had transmitted almost 13,000 GWh, a 12 per cent increase from the previous year.
"That's a new record for Transend and the most in any year since Tasmania joined the national electricity market in 2005," he said.
While the amount of power used in Tasmania remained relatively steady, more than double the previous year's amount was exported to the mainland.
Mr Clark said Transend had achieved its two goals of providing a reliable service to customers as well as driving down costs.
"In other words, we are managing the business with no real increase in revenue. That helps to put downward pressure on prices for all electricity consumers," Mr Clark said.
Work to merge Transend with Aurora Energy's distribution business is underway with the single entity to be known as TasNetworks, on track to start operating July 1 next year.
"The fact that we achieved those results, while maintaining a safe and reliable service to our customers and preparing for the network merger, is a credit to everyone on the Transend team," Transend chairman Don Challen said.
