PEACE RIVER SITE C HYDRO PROJECT AN OPTION TO HELP CLOSE B.C.’S GROWING ELECTRICITY GAP SUMMARY: STAGE 1 REVIEW OF PROJECT FEASIBILITY DECEMBER 2007 Peace River Site C Hydro Project An option to help close B.C.’s growing electricity gap Stage 1 Summary This document provides an overview and summary of the Stage 1 review of the proposed Site C project. This Stage 1 review of project feasibility was a review of existing studies and historical information about the Site C project, with a view to determining if there is enough potential to address key impacts to move to the next stage of project planning and development. This information was reviewed in the context of projected energy demand now and into the future, and an analysis of the expected supply to meet that demand. S ITE C A growing province with growing electricity needs 1 STAGE A heritage built for generations six years, BC Hydro has been a net importer of electricity.

In 2006, BC Hydro produced its Integrated Hydroelectricity and our province’s economic Electricity Plan, which forecasted our province’s development are inextricably linked. In the two long-range electricity needs and examined decades that followed the creation of BC Hydro existing and potential resources to meet in 1961, our province undertook some of the those demands. This plan notes that electricity most ambitious hydroelectric construction consumption in B.C. is expected to increase projects in the world.
