PHASE II

Water Balance and Hydrological Analysis

Ensemble Meteorological Dataset for North America (EMDNA) forcing data was used to simulate a historical streamflow record, confirm the hydrological feasibility of the project, and establish an average annual water balance for the site.

R = P − ET − ΔS − GW =

1149 mm−861 mm−1.9 mm−7.9 mm =

278 mm

For the total watershed area of 5.557 km², this result corresponds to an average outflow of approximately 0.05 m³/s.

Operational Plan

Operating the facility on a cycle of 8 hours of generating to 10 hours of pumping was the most effective amongst the tested scenarios. Based on 2022 pool prices in Alberta, the facility could expect to have a net revenue approximately between $70-155 million per year; translating to an annual percentage variance of 12.03% and 29.28%, respectively.
