Water Supply

Water supply for the Project will be provided from the Bow River under a long-term licence. Conveyance of the water to site will be through the existing EID canal system under contract. The annual water demand for the initial Project phase will be approximately 35,000 m3 (28 AcFt). At full 450 MW production rates, the total Project water consumption will increase to 880,000 m3 (713 AcFt) annually.

Water Storage

IEPS also plans to contract to use an EID owned and operated reservoir to meet the project’s water storage needs. Two reservoirs, Kitsim and Newell are currently under consideration. The projected water demand even at projected production rates of 50,000 tonnes per year would be only a small percentage of the reservoir’s firm live storage capacity. This will ensure that electrolyzer operations can continue during even significantly drier than normal years. At the same time, the use of an already existing reservoir will also significantly reduce the environmental footprint of the Project.

It is expected that the distance from the reservoir to the site combined with the quality of the water within the reservoir will be the key factors in selecting the optimal storage site. The latter is particularly important since to be usable within the electrolyzers, the water must undergo a significant level of treatment and high levels of impurities in the raw water feed will increase treatment costs significantly. IEPS is currently working with the EID to establish the best storage location as well as the optimal system for moving water from storage to the facility.
