Burden sharing mechanisms for the share of renewable electricity consumption or production

The developed 'REBUS model' quantifies the impact of trade in burden sharing mechanisms and the implementation of different rules to setting regional and (inter) national targets for the share of renewable electricity consumption or production. Results are obtained for a range of so-called burden sharing options that reflect differences in economic, social and geographical possibilities to increase the share of renewables in individual geographical regions. The REBUS model furthermore analyses the impact of other supporting mechanisms for renewable electricity on the effects of a burden sharing mechanism.

An important condition of renewable energy policy is often that the target is reached in a cost-effective way. An important means to reach this cost effectiveness is to introduce the possibility of trading. In the REBUS model this is implemented by means of trade in green certificates, which in fact represent different ways of burden sharing. Countries can lower their overall costs of achieving the targets by importing certificates instead of realising (a part of) their target domestically, or (in case of abundant relatively cheap RES-E potentials) export certificates. The REBUS model allows for analysing the benefits of introducing such a trading scheme. Note that in the REBUS model it is assumed that trading occurs through the trading of green certificates, and not of the physical electricity itself.

The main questions that can be answered by the REBUS model include:
- What are the costs of realising (inter) national or regional targets for RES-E?

- What will be the expected price of tradable green certificates in the region?

- What are the cost benefits of interregional trade in tradable green certificates?

- What it the impact of applying different burden sharing rules to achieving RES-E targets?

- Which technologies are likely to penetrate in the coming years on the basis of cost-effectiveness?

- What is the effect of changes in the cost or potential of individual technologies on the penetration of this technology and on the resulting costs of achieving renewable electricity targets?

- What are the effects of other national or regional supporting policies on the certificate price and the costs of achieving targets?
