The Zeballos Lake Project is a 23 MW (approx.), run-of-river hydroelectric project (HEP) located Zeballos Lake, B.C. (Vancouver Island). It is owned and operated by the Zeballos Hydro Limited Partnership (ZLHLP).
The Zeballos HEP is a renewable resource project that consists of a two powerhouses, which uses the natural drawdown and water storage capacity of Zeballos Lake to generate 100 GWH/yr. of electricity. The project draws water from the lake via a tunnel and penstock, and directs it through two Francis Turbines, which then return the water to the lake outlet in Maraude Creek. Energy is transmitted through a 20 km, 138 kV transmission line, which interconnects to BC Hydro’s grid at Tahsis. The project maintains a fish flow at the upper reach of the fish habitat in the Maraude Creek downstream of Zeballos Lake. Our involvement in the project has consisted of providing IEM services during the proposed seal of the existing natural rock dam at the outlet of the lake.
