Power supplies in NSW should "be fine for the foreseeable future" but the state's energy minister says he is monitoring the situation closely.
Matt Kean is "cautiously optimistic" about the continuity of power supplies after asking residents to reduce their energy usage on Wednesday night to prevent blackouts when a number of coal-fired power stations unexpectedly failed to come online.
The call came after the minister spoke to Australian Energy Market Operator AEMO chief executive Daniel Westerman, who told him a generator at the Bayswater Power Station wasn't coming back online.
