The Lidsdale Siding is a rail loading facility which automates the transfer and dispatch of coal from Centennial Coal's Western Coal Services Project to domestic and international markets via rail.

The current approval for Lidsdale Siding allows for train movements to receive and unload one coal laden train per day, and load and dispatch seven coal laden trains per day.

Loading operations are not permitted to be carried out on the same day as unloading operations under the current approval.

The modification that Centennial Coal has submitted includes realigning the number of train movements arriving at and departing the facility.

The proposal does not increase the maximum allowable daily or annual train movements to and from the site.

According to a report put to Lithgow City Council to notify it of the application, the modification would allow more coal to be received at the site and assist with the ongoing supply of coal to Mount Piper Power Station.

The report also stated that the proposed modification would allow an alternative source of coal of suitable quality to be transferred to Mount Piper Power Station and would supplement coal supply shortfalls from Springvale Mine.

"If no emergency coal supply provisions are put in place to address potential coal supply shortfalls there is a risk that declining stockpiles at the Mount Piper Power Station will impact the efficiency of operations and threaten the reliable supply of electricity to NSW," the report states.
