Modeling technology deployment costs on the basis of learning rates is not easy – if a low pessimistic learning rate is assumed for a technology, it may be squeezed out by technologies with higher learning rate; if a highly optimistic learning rate is assumed, it may lead to unrealistically high estimates of potential cost reductions.
The International Energy Agency (IEA) camp up with estimated commercialization costs of power generation technologies, based on reasonable learning rates (Table 18.2)
