Legislated Constraints
(a) Achieve electricity self-sufficiency(b) Utilize DSM to reduce expected demand by 66% by
2020(c) Generate 93% of electricity in BC from clean or
renewable energy(d) Keep electricity rates amongst the lowest in North
America(e) Reduce GHG emissions by 33% below 2007 levels(f) Become a net exporter of electricity from clean or
renewable resources(g) Achieving these objectives without the use of
nuclear power

Electricity Supply Resources
Power Smart (demand-side management program); Heritage Hydro (existing hydroelectric units and the proposed
Site C facility); Heritage Thermal (existing thermal units); Resource Smart (upgrades to existing heritage hydro
facilities); Downstream Benefits (the Canadian Entitlement from the
Columbia River Treaty); Non-Firm/Market Imports 2,500 GWh allowance, and Electricity Purchase Agreements (EPAs) with IPPs. Of these seven mechanisms, only three (Power Smart,
Resource Smart, and EPAs) are able to increase energy supply in the future given the policy constraints that currently exist within the province.

Conclusion
Remove electricity and replace revenue in definition of self-sufficiency
Revenue self-sufficiency would require export revenues to exceed import costs
Allows profitable trading activity to maintain low rates reduce the need for expensive EPA
