Rains bring some relief to hydro dams

  • Total energy in storage is currently at 13 per cent, an increase of 0.2 per cent since last week.
  • Progress has been made installing three 25MW dual fuel units at the decommissioned Bell Bay Power Station site. The three units are on target to be online in mid-May.
  • Hydro Tasmania expects to have 220MW of additional generation online by mid-May, additional capacity will be used optimally in combination with existing hydro, wind and gas generation.

 

Tasmania has benefitted from welcome rains and, for the first time in seven months, water storages have increased.

Water storages are now at 13 per cent, an increase of 0.2 per cent since last week.

Minister for Energy Matthew Groom said storage levels are strong not only because of recent rainfalls, but also because the government’s Energy Supply Plan is working.

“Storages are likely to remain above the projected low of approximately 12 per cent and because our Energy Supply Plan is taking pressure off the system, the storage level at Lake Gordon has increased by 0.3 per cent to 6.5 per cent and the storage level at Great Lake has also increased by 0.3 per cent and now sits at 10.9 per cent,” he said.

Forecasts suggest there will be additional rainfalls in catchment areas this week.

“While it’s pleasing to see storages increase this past week, significant challenges in relation to energy are ongoing and that’s why the Government remains committed to continuing the implementation of the Energy Supply Plan,” Mr Groom said.

“The other significant development is the progress made installing three 25MW dual fuel units at the decommissioned Bell Bay Power Station. The three units are on target to be fully installed later this week and will be online in mid-May.”

With installation of diesel generation, Hydro Tasmania expects to have 220MW of additional generation online by mid-May. This additional capacity will be used optimally in combination with existing hydro, wind and gas generation.

On Saturday, the Trent unit at the Tamar Valley Power Station was shut down after an exhaust gas leak was identified. The fault was identified and Hydro Tasmania said the Trent will return to service by the end of the week.

Basslink has advised the next phase of repairs to the interconnector will commence this week, subject to suitable weather conditions.
