Projects in Development

  • WaterCharger Battery Storage – Cochrane, AB

    WaterCharger Battery Storage – Cochrane, AB

    Quick facts:

    • Location: Cochrane, AB
    • Fuel: Energy Storage
    • Capacity (MW): 180
    • Ownership: 100%
    • Operator: Yes
    • First on-stream: 2023
    • Revenue Source: Merchant
    • Builder: Yes

    The WaterCharger Battery Storage Project (“Project”) is located on approximately nine acres of TransAlta owned lands that are part of the Ghost Hydro-electric facility. The Project is located about 18 kilometers west of the Town of Cochrane in Rocky View County. TransAlta wishes to develop this Project to provide reliable electricity service to the Alberta electrical grid and support the development of additional renewable energy for Albertans.

    The battery facility is designed to be charged by electricity produced by the existing Ghost Hydro-electric facility when demand is lower, for example at night, and discharged to support the stability of the electric grid during times of higher demand. It will generate up to a maximum of 180 MW with potential for two phases.

    Project update

    On January 21, 2022, TransAlta filed its Battery Storage Facility Application to the Alberta Utilities Commission (AUC) for the WaterCharger Battery Storage Project. The application has been assigned Proceeding Number 27109.

    To review the application and associated reports filed with the AUC, you can access them through the AUC website. To access the application, you must create an account and then search for the filing using the proceeding number 27109.

    In December 2021, TransAlta published the following reports on the Project webpage and these remain for your review:

    Some of these reports appear as drafts at this stage as they are considered living documents and will be updated as the project progresses. For example, the Environmental Protection Plan and Noise Impact Assessment will be revised once the battery vendor is selected. The documents will be finalized prior to the start of construction. The reports on this webpage will be updated as the project progresses.

    As we have received recent questions related to the risk of battery fires, the risk of leaching or leaking from the batteries, noise concerns and the construction of power lines, please refer to the Stakeholder Update – December 2021 for answers to these questions.

    Regulatory requirements

    The AUC issued a notice of hearing on May 16, 2022 for the WaterCharger Project. The commission will host a virtual hearing, commencing on August 3, 2022, at 10 a.m.

    Learn more about the AUC’s regulatory process on their website.

    The Tempest Wind Power Project (the Project or Tempest) is a proposed 100-megawatt (MW) wind project located approximately 22 km south of Taber and 32 km east of Lethbridge in Warner County, Alberta. The Project will consist of up to 22 wind turbine generators, each with a capacity to generate between 4.5 to 6 MW of power. The final turbine technology will be confirmed as the project advances through the development process.

    The Project is being developed by TransAlta Corporation and we plan to construct, own and operate Tempest wind facility. Current target commercial operation date for the Project is December 2024. As part of our ongoing development efforts, TransAlta has completed the full suite of environmental studies required by Alberta Environment and Parks; continues collecting wind data and advancing its engineering efforts; advancing the project through the AESO interconnection queue; and is on track to submit an application for permit and license to build, own and operate the facility to the Alberta Utilities Commission (AUC) in fall of 2022.

    More information will be shared about the Project in the coming months as we kickoff of stakeholder consultation in accordance with the AUC’s Rule 007 Participant Involvement Program. We welcome and value stakeholder participation and feedback. This webpage will be updated with new information as it becomes available.
