There is a lot of talk about the impact of BC Hydro purchase agreements with independent power producers but people seem to think it is all from run of river projects, but that is not really the case all. People also blame the Liberals for independent power production, but the reality is that more than half of the power purchased by BC Hydro comes from projects predating the BC Liberal government.
As of October 2013 BC Hydro has 82 active energy purchase agreements in place producing 15,317 GwH/yr. The data comes from a list regularly provided by BC Hydro.
The six largest EPAs represent 8,474 GwH/yr of power, 55.3% of the IPP power BC Hydro purchases. Only one of them is a run of the river hydro project.

McMahon Generating gas fired Taylor 840
Arrow Lakes Hydro storage hydro Slocan 767

Non storage hydro 46 3,624 23.7%
Gas fired 2 3,140 20.5%

Wind 3 1,031 6.7%
Small storage hydro 8 789 5.2%
Other 4 271 1.8%
Biogas 6 91 0.6%
Biomass tend to be wood waste cogeneration plants
Other is three energy recovery projects and one municipal solid waste project
Biogas comes from landfills
1/5th of the private power comes from fossil fuels and just over a quarter comes from traditional large storage hydro projects. This means only 53.5% comes from what could be called green power.

2006-2009 includes 3,307 GwH/yr from Alcan which is a renewal and not a new agreement. BC Hydro has purchased power from Alcan since 1961. If one considers Alcan pre Liberal power, only 6,728 GwH/yr is purchased from projects approved under the BC Liberals, or only 43.9% of the power purchased by BC Hydro from IPPs.
