  5. Planned and possible generation Around 6,000 MW of generation capacity planned or possible to 2015. Only around 1,500 – 2,200 MW is ‘economic’ (in terms of cost) under most scenarios

  6. Likely new generation to 2015- including a carbon charge • Around 2,200 MW of capacity (from the approx. 6,000 MW listed as planned or possible) is likely to come into the stack by 2015. Primarily small wind and geothermal in the short-term, given likely step in price from carbon charge.

  7. Likely new generation to 2015- excluding a carbon charge • Around 1,600 MW of capacity (from the approx. 6,000 MW listed as planned or possible) likely to come into the stack by 2015. Less small wind and geothermal plant commissioned than carbon charge inclusive scenario. Not necessarily less electricity generated, but different plant mix with higher output for thermal plants.
