Giving the green light for BC small hydro: independent power producers are taking up the challenge to develop British Columbia’s plentiful supplies of small hydro. Suzanne Pritchard reports. International Water Power & Dam Construction, Dec 2008 v60 i12 p40(2)
“Well known for its mountainous topography and abundant rainfall, the coastal regions of British Columbia can have more than 4m of rainfall per year. In addition, the province’s sheer size, run-off from snow melt and thousands of creek reaches mean it is also ideally suited for run-of-river hydro power. ‘There is phenomenal potential for small hydro here,’ says Mike Wise, vice chair of the hydro committee for the Independent Power Producers Association of British Columbia (IPPBC). ‘The hydro sites are just fantastic.'”
“Beyond British Columbia’s ideal geographic setting for hydro power is the unique ‘green’ design of the run-of-river projects. ‘This design is very different to hydro projects almost anywhere in the world. It is the sole reason why we are judged to have the lowest environmental impact,’ says Steve Davis, president of the IPPBC.
“‘We do not have big storage reservoirs,’ says Davis. ‘In fact, typical headpond is only the size of a soccer field. While most others have short, thick pipes in tall concrete dams, our projects have long, narrow steep pipes and low rubber weirs. Our glaciated hanging valleys and alpine lakes enable us to locate the projects above a natural fish barrier and still get lots of head. So unlike most other hydro projects we are able to avoid directly impacting fish habitat.'”
Want to be familiarize yourself with run of river research both in terms of both the environmental and engineering aspects? What are the issues? Want to separate the hype from the reality?
The following databases will gave you access to international research dealing with run of river power generation:
ASFA and Geobase will give you access to environmental and fisheries related research. Compendex is excellent for the engineering side of run of river power generation.
