AGL Energy's Andy Vesey says coal investment doesn't add up |AFR

AGL energy chief executive Andy Vesey and other power bosses said the economics of investing in new coal plants don't add up compared with wind and solar power.

Speaking a day after Prime Minister Malcolm Turnbull said the federal government could invest in new coal plants to shore up supply, Mr Vesey said he had examined the numbers and could not commit AGL's capital to coal plant.

He believed the energy security plan outlined by Chief Scientist Alan Finkel was "comprehensive" and should be backed, and joked that as soon as you think you're up to date with energy policy "a flash on your phone" changed everything again.
