Former West Australian premier Brian Burke is among a growing list of potential bidders looking to develop a major renewable energy project in the state's coal heartlands.
Mr Burke, who was premier during the height of the WA Inc. saga in the 1980s, is involved with an entity known as Collie Pumped Hydro, which wants to use coal voids to build a pumped hydro plant in Collie, 180 kilometres south of Perth.
