Blackout, price risks loom for businesses in S Australia

Melbourne

RAPID growth in wind and solar power in South Australia is raising the spectre of blackouts and soaring prices for businesses like global miner BHP Billiton as cheaper renewables have pushed traditional thermal power plants to close.

South Australia uses wind farms and rooftop solar panels for 40 per cent of its power, more than any part of the country. However, businesses that depend on the steady power provided by coal- and natural gas-fired generators are concerned about disruptions as the state relies more on intermittent renewable energy.
