When the NEB is making those forecasts, it provides more than one case, so we use the reference case as the baseline. It takes into account a lot of factors at a high level, and I'm not privy to everything used in balancing out how it arrives at its forecasts. I can't specifically address the storage issue.
However, we do know that in Alberta, they often speak about how much petroleum product they can store right now. Sometimes, you'll see references in the papers to storage in the 30-million barrel range.
I don't know how the NEB, in particular, would factor storage into its forecasting. I'm sorry.
