So where are some of the BC Hydro production differences coming from? In fiscal 2008 there was more water available for production. Before 2003 the Burrard thermal plant produced up to 3974 GW/h per year, since then it has produced about 150 to 600 GW/h per year.
Since 2001, demand for power in BC has surpassed the ability for BC Hydro to produce the power. The last year in which BC Hydro produced enough hydro electrical power for BC needs was in 1998.
How has BC Hydro met the shortfall? In large part through long term private power contracts. In the late 1990s this was about 8000 GW/h per year. Now it is about 10 500 GW/h per year. The surplus has always been sold by BC Hydro.
In the late 1990s BC Hydro purchased about 2000 GW/h per year of IPP power. Now they buy about 7500 GW/h per year.

Not wanting to be a stickler, but how can there be a shortfall if BC Hydro sells surplus power?
I realize we buy "dirty" power from Alberta in the wee hours of the morning, but some factual references would make your argument stick. :)
