Mr. Tim Gould:

There certainly are plenty of countries that have designed auctions very effectively. Within the IEA family, Brazil is a good example of a country that has managed this very well. Mexico is a newly joined member of the IEA that has really contributed some very good examples of how auctions can be designed both to bring renewables into the system and to bring in the type of technology that best matches the needs of the system. It is not a guarantee that in a system that has good solar potential, adding a PV, photovoltaic, system is necessarily the right thing to do. There may already be a fairly saturated market at the key times of day for PV systems. It may be necessary to find a different technology mix that would be the best complement to the system. Thinking through the regulatory ways of encouraging both renewable investment in general and the right type of renewable in the right place in the system is the challenge many policymakers have faced. There are some good examples of that in the IEA family.
