Marginal Abatement Costs (MAC) curves
ƒ Costs vary depending on what happened in previous years
ƒ ITC – Induced Technological Change
ƒ Inertia in energy system – lifetimes times for power plants etc
ƒ Using static MACs does not capture this
ƒ But FAIR tries to take into account by interpolating between 3

include: macro-economic effects, gains of ancillary benefits and
cost/gains of changes fuel trade

ƒ Discount rate of 5%, but energy system also 10% (investments
