In modern wholesale power markets the power stations best able to sell their power are those whose variable cost is lowest. What this means is that in the long term to get a good return on your money it is better to build power stations with low variable costs of energy production. In the USA there has been a big fall off in the building of gas fired power stations because they have low capital costs and high running costs (gas is expensive). It is economic vandalism for the ACT to build a gas fired power in this day and age. The price of gas is going to go even higher than it is today - perhaps even 4 times its cost - because gas can be used for transport. The ACT should ONLY consider building the lowest variable cost power sources for its future energy. Today that is geothermal and solar thermal both of which produce power at lower variable cost than any current or future fossil burning plant. If the ACT government continues down the path to build a gas fired power station then in five years time it will have to live with the consequences of a power plant that rarely operates but takes up valuable land.
