Long Lake Joint Venture
Developer Background
Regional Power
developer and operator of hydroelectric power plants since 1985, over 120 plant years of operating experience
Developed hydro plants in BC and Ontario
Regional has 6 hydroelectric development sites “under contract” representing 97 MW in capacity
Two 11 MW sites on Bear Creek, near Sechelt currently under construction and Long Lake access construction started summer 2010
a subsidiary of Manulife Financial
Long Lake Joint Venture
Developer Background
Joint Ventured with Premier Power
Corp. in Long Lake Project
Premier’s affiliate company,
Summit Power, owns and operates
two hydro developments in
southwestern B.C.

Long Lake Joint Venture
Project History
Several hydro schemes
powered the old Premier
and Big Missouri mines
during 1923 through
1956
Developments on lower
Cascade & Fletcher
Creeks provided power
to nearby Premier mine
and townsite

Long Lake Joint Venture
Project Background
Westmin studied Long Lake hydro concept to service a new 2,000 tpd mine in late 1980’s
Plans for the hydro plant were shelved when BC Hydro extended the 138kV transmission line from Aiyansh to Stewart
Premier Gold mine operated until mid 1990’s
Long Lake Joint Venture
Project Background
Summer 1999: Premier Powerinitiated technical, environmental and socioeconomic investigations
Late 2002: Premier Power and Regional Power formed Long Lake Joint Venture to advance the development
Early 2005: Completed regulatory review process for 2.83cms (CEAA / CWL)
Fall 2008: Project was successfully bid into BC Hydro’s 2008 Clean Power Call process
Summer 2010: Awarded Energy Purchase Agreement
Long Lake Joint Venture
Project Design
Redevelop concept using Westmin 1980’s strategy
Develop hydro power to optimize utilization of hydrologic resource
– 31 MW installed capacity
– 5.0 m3/s design flows
– utilize storage on Long Lake
– develop 776 m gross head
