This report by Concept Consulting compared input values used in the previous modelling of the EAF against reality. It found that if actual values had been used the EAF would be lower than its current level.
The EAF is an estimate of the impact of the New Zealand Emissions Trading Scheme (NZ ETS) on electricity prices. We are currently seeking feedback on parameters and values to support modelling of the electricity allocation factor (EAF).
