Tesla has won a contract with Transgrid, the company that operates the New South Wales (NSW) portion of Australia’s National Electricity Market (NEM). The contract dictates that Tesla will install Powerpack batteries at sites throughout NSW in Sydney. The first 250 kilowatt, 500KW/h Powerpack will be installed at the Alexandra Canal Works depot in Sydney.
The Powerpack contract is intended to help smooth the uneven supply of power from solar and wind energy sources. These sources often spike during daylight hours that don’t correspond with demand, necessitating some device for storage. It is also to be part of the trial “demand response” technique for moderating prices and avoiding blackouts.
