Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Just by eyeballing the graph you can get an idea of the price range of gas and coal. If we assume (back-of-envelope-style):

The graph shows a range of electricity price using gas of 5 - 7.5 cents/kWh.

1m2 of natural gas (methane) contains ~10kWh of energy and the power plant is 40% efficient, so 1m2 gives 4kWh of electricity. That means the estimated price of producing electricity by gas is 20-30cents/m2 of gas. Note that this is the cost to the power plant operator per m2 consumed, which means the price of gas + running costs.

A quick googling shows that the price of Russian
 gas in Dec. 2009 was ~23cents/m2 .

I don't know if the gas fired power plant efficiency is realistic but if you use the expected price increase from $30/ton CO2 you get a figure for the efficiency about 40% (but the error bars are too big to fit into the comment box).

For coal the price range is 7-9cents/kWh. High-quality coal contains ~9kWh/kg. Again with 40% efficiency that translates into 2.5-3.2cents per kg of coal ($25-32/ton), again neglecting non-fuel costs in production.

Real capricorns don't believe in astrology.
