Labor offers solar panels and Tesla batteries for 50,000 South Australia homes

'Virtual' power plant will cut bills, premier says, as Turnbull attacks renewable policy at Liberal campaign launch

A network of at least 50,000 home solar systems backed up by battery storage will create the world's largest "virtual" power plant to cut energy bills, Jay Weatherill has said.

The South Australian premier said a trial was already under way to install solar panels and Tesla batteries on 1,100 Housing Trust homes. The cost would be financed by the sale of electricity. The power generated by the solar panels and the batteries would not be owned directly by the households.
