Long Lake Small Hydro Project Minerals North 2005 29 April 2005 Presented by David Carter Regional Power Inc. Stuart Croft - Summit Power Group
Project Location 25 km north of Stewart, in northwest B.C. Situated near historic Premier & Big Missouri mining camps Moderated coastal climate and terrain ideal for small hydro Long Lake valley looking south
Developer Background Doran-Taylor 5.3 MW Project 40 km west of Port Alberni Premier Power s affiliate company, Summit Power, owns and operates two small hydro developments in southwestern B.C. Soo River Project Whistler - 14 MW commissioned 1994 $18 million Doran-Taylor Project Port Alberni - 5.3 MW commissioned 1996 $8 million
Developer Background Regional Power Inc. developer and operator of hydroelectric power plants since 1985. developed 3 small hydro plants (2 in BC and 1 in Ontario) and has rehabilitated 3 existing power plants in N Ontario. Regional has 4 hydroelectric development sites under contract representing 93 MW in capacity Bear Creek, Long Lake and Ucona River in BC Anglier in Quebec Near term development prospects with an aggregate capacity of 135 MW. a subsidiary of Manulife Financial
Joint Venture Background Doran-Taylor Hydro tailrace (Oct 98) (Fisheries Renewal BC project co-sponsored by Summit Power, DFO, Hupacasath First Nation, MC Wright & Associates) Innovative approach to Project development Identify environmentally and economically sound opportunities Established a favourable, cooperative relationship with government agencies, stakeholders Sechelt Creek Hydro spawn channel (Sep 03) (A cooperative arrangement between Regional Power, DFO, Sechelt First Nation)
Project History Several small hydro schemes powered the Premier and Big Missouri mines during 1923 through 1956 Developments on lower Cascade & Fletcher Creeks provided power to nearby Premier mine and townsite
Project History Cominco built dam at Long Lake to provide 8500 dam 3 storage for Big Missouri mine power development Long Lake Concrete Arch Dam: length - 30 m height - 12 m built - 1937 demolished ca 1980 Provided firm power of approx. 1000 kw year round to mine and townsite
Project Background Westmin studied Long Lake hydro scheme to service new 2000 tpd mine in late 1980 s Plans for 7.5 MW hydro power plant shelved when BC Hydro extended transmission line from Aiyansh to Stewart Premier Gold mine operated until mid 1990 s Mine is presently executing closure plant, Boliden seeking to dispose of property
Development Background In 1999, Premier Power entered into Agreement with Boliden to acquire facilities & infrastructure, rights-ofway, roads, etc. for Long Lake small hydro development Provides Boliden cost relief, additional security of supply for ongoing water treatment obligations Late 2002: Premier Power and Regional Power formed Long Lake Joint Venture to advance the development Successfully bid into BC Hydro s 2002 CBG power acquisition program and executed EPA in spring 2003
Development Concept Reinstate historic development at Long Lake with concept refined from earlier Westmin scheme Develop hydro power scheme to optimize utilization of hydrological resource 16 MW installed capacity 2.83 m 3 /s design flows utilize storage on Long Lake develop 775 m head Utilize existing transmission infrastructure to deliver energy for sale to BC Hydro
Feasibility Design 20 m high rockfill dam & intake structure at outlet to Long Lake 1 m buried penstock following Big Missouri haul road 7.5 km to vicinity of Premier Gold mill site Powerhouse with one 16 MW multijet Pelton-type turbine generator unit Automated protection & control system designed for unattended plant operation Power transmission via existing pole line to BC Hydro grid at Stewart Short tailrace to return water to Cascade Creek
Feasibility Design Annual generation of approx. 100 GWh Total Capital Cost estimated at $40 million 2 year construction schedule 5.3 MW Pelton turbine (similar to unit proposed for Long Lake)
Development Schedule Regulatory Review concludes Spring 2005 Commence construction Summer 2005 Commercial operation Winter 2006 / 2007
Benefits Replacement investment and economic stimulus for Stewart, NW BC Sustainable, long term resource development to produce Green Power Maintains valuable infrastructure Affords numerous environmental benefits
Long Lake Hydro Back to the Future Excellent small hydro development opportunity hydrology storage infrastructure Benefits to stakeholders Developers Stewart Province of B.C.
