The Kurri Kurri Lateral Pipeline (KKLP) is a gas transmission and storage pipeline that will connect the Hunter Power Project in Kurri Kurri, to the Sydney to Newcastle pipeline, near Newcastle, in New South Wales.

The KKLP Project comprises the following main components:

• A 21 km buried steel DN350 (approximately 14-inch), medium pressure (up to 6.9-megapascal) transmission pipeline to provide a gas supply from the existing Sydney to Newcastle pipeline to the Hunter Power Project.
• A compressor station at the end of the transmission pipeline to boost gas pressure to the required inlet pressure of the Hunter Power Project.
• A 24 km buried steel DN1050 (approximately 42-inch), high-pressure storage (up to 15.3-megapascal) pipeline downstream of the compressor station to hold up to 70 TJ of gas ready to supply the Hunter Power Project at the required inlet pressure.

The KKLP Project is located within the Cessnock City Council, Maitland City Council and Newcastle City Council local government areas, with the closest communities including Kurri Kurri, Heddon Greta, Cliftleigh and Gillieston Heights. It is expected to be completed in 2025.
