Oilfield & Industrial Customers

Our Services

Did you know our industrial and oilfield customers use more than 65% of the energy demanded in our service area? We’ll make sure you have the power you need when you need it. Contact us when you want to:

  • Plan a project that needs a new electricial service or an upgrade to an existing electrical service
  • Permanently remove electricity distribution assets from your site
  • Move a line or do road work
  • Review the distribution contract demand for your site
  • Turn your power back on – we have crews available 24/7 to respond to power outages: call 1 800 668 2248 or check the status of your home with the My ATCO Electricity App

Distributed Generation

This page breaks down each phase that is involved in connecting your project to the Alberta grid.

ATCO’s Role
Our team of experts designs and builds the distribution infrastructure needed to safely connect a generation facility to the Alberta Interconnected Electric System. Determining the type and size of generator is the responsibility of the power producer and a third-party electrical consultant, if needed.

Before Requesting Connection
Before submitting a connection request, it’s important for power producers to understand all technical and operating requirements. The following documents provide the details. Please review before requesting connection.


 Prior to the submission of an application, you may direct any questions to

Distributed Generation Interconnection Process

We work with power producers in our service area to safely connect generation facilities to the distribution system and ensure generation does not disrupt service reliability or pose safety risks. 

Click through the phases below and review our process map for more information. 

  • Phase 1 - Application and Feasibility Assessment

    What do I do first? Fill out the application form. You will need to know the size and type of generator as well as the requested location of interconnection. Once your complete application and fees have been received your project will enter our interconnection process and project queue.

    What happens? The Phase 1 Feasibility Assessment is a technical project review to determine the high-level distribution and transmission scope of work required to connect your project, as well as an initial assessment of the interconnection costs and commercial obligations.

    A further detailed review is required in later phases of the project. A high-level feasibility study, project scope, and an order of magnitude cost estimate for the interconnection of the generator will be presented in the Phase 1 Interconnection Proposal, which we will provide for your review.

    What will it cost? Application fees start at $4,128 and will be assessed based on your requested project needs.

    What's next? Once you’ve reviewed the proposal and would like to move forward, full acceptance of the Phase 1 Interconnection proposal and payment of identified fees is required to proceed to the next steps. Fees for the next phases of the process are based on the scope required and whether the project requires a submission to the Alberta Electric System Operator (AESO) for a Behind the Fence Connection and if transmission studies are required.

  • Phase 2 & 3 - Detailed Distribution and Transmission System Interconnection Assessment

    Estimated fees for Phases 2 and 3 will be determined after Phase 1 is complete and vary based on the scope of the project and whether the interconnection requires a submission to the AESO for a Behind the Fence Connection and if transmission studies are required. The fees generally range from $40,000 to $95,000.

    Phase 2 includes the detailed distribution design and a more in-depth estimate and proposal.

    In Phase 3, a transmission protection and control study for the local transmission interconnection will be prepared.

    Under certain criteria, the project may require an application for System Access to the AESO as a Behind the Fence Connection, and additional power flow studies may be required. These additional transmission studies will be completed by ATCO.

  • Phase 4 - Final Interconnection Proposal and Acceptance

    Upon completion of the detailed studies and estimates in both Phases 2 and 3,  we will provide you with a  Final Interconnection proposal, which has the detailed distribution and transmission project scope and estimates, and any additional transmission-related estimated costs for interconnection to the system.

  • Phase 5 - Construct & Prepare to Energize

    Full acceptance of the Final Interconnection proposal and payment of the estimated costs is required to proceed to the execution phase of the project.

    Before energization, the Electric Service Agreement, as well as the Interconnection and Operating Agreement, will be finalized.

  • Phase 6 - Commission, Energize & Close

    Once all the pre-commissioning and interconnection requirements have been fulfilled, the Interconnection is commissioned and energized. The final project costs will be reconciled, and the project can be closed. 

Generation Hosting Capacity Maps

Generation Hosting Capacity Maps are intended to provide an estimate of how much new generation can be installed in an area of the distribution system. The estimated ranges displayed in the maps were calculated to ensure no significant system parameter (e.g., voltage, conductor ampacity, or apparatus rating) violation occurs.

The amount of potential generation reported in the maps is an approximation and is based on general system assumptions. For example, system loading information, existing generator operating modes, and nearby connected loads are all assumed as typical system behavior, and not necessarily custom to a particular site. Distributed Energy Resources (DERs) currently in queue are also excluded. To confirm the amount of generation that can be interconnected to a site, an application must be filed with ATCO and all necessary system information will be used to generate a feasibility study.

The values displayed in the maps represent potential amounts that may be accommodated by the distribution system in its existing form and does not consider any upgrade that could be undertaken to significantly expand these values.
