Welcome

The AESO welcomes you to its Open House on the need to reinforce the electricity system in the Central East (Cold Lake, Vegreville, Provost) area.

Our Principles for Public Involvement in Transmission System Planning

1. Every member of the public must have an opportunity to comment on the plans.

2. The public must have an opportunity to be informed in a timely manner of the direction, plans, status of issues and decisions related to a project.

3. The experience and expertise offered through public involvement is used to improve the quality and implementation of decisions.

4. The public involvement process and the rationale for decisions are transparent.

A STAKEHOLDER is Anyone who has a “stake” in the outcome of the project

www.aeso.ca

The AESO is:

A not-for-profit statutory company, operating in the public interest.

Independent of any company or person with a material interest in the electric industry.

AESO Key Functions:

• Operate the wholesale electric market

• Plan the transmission system

• Arrange access for demand and generation

• Direct day-to-day operation of the transmission system

www.aeso.ca

Transmission System Planning at the AESO • 20-Year Transmission System Outlook – generation and load focused; high level conceptual transmission alternatives • 10-Year Transmission System Plan – roadmap for transmission development and context for Needs Identification Documents • Individual Needs Identification Documents

The AESO’s Transmission System Planning Process Two main drivers of transmission planning: 1. Load growth (demand) 2. Generation development (supply)

Central East (Cold Lake, Vegreville, Provost) Study Area

Cold Lake to Vegreville to Provost study area roughly comprised of:

• County of Paintearth • M.D. of Provost • M.D. of Wainwright • Beaver County

• County of Fort McMurray Vermilion River • County of Two Hills • County of Minburn Cold Lake • County of St. Paul Bonnyville St. Paul • M.D. of Bonnyville Two Hills Edmonton Vegreville Lloydminster • Flagstaff County Viking Wainwright

Overview of Need – Central East (Cold Lake, Vegreville, Provost) Area

The transmission system in this area lacks the capacity to support additional demand or to integrate new generation

• Demand for electricity in this region is growing rapidly

• Demand growth areas: • Cold Lake, Wainwright and Provost areas • Demand is expected to double over the next 10 years

• Gas generation and wind interest in this area: Over 500 MW

TFOs and their Roles

AltaLink and ATCO Electric are the transmission facility owners (TFOs) whose service areas fall within the Central East (Cold Lake, Vegreville, Provost) area.

Once the TFOs have determined their recommended specific routes, they must file Facilities Applications with the Alberta Utilities Commission for approval to construct and operate the required transmission facilities.

Route Selection

When evaluating potential routes, TFOs consider the following factors:

• Agricultural • Electrical • Residential • Visual • Environmental • Other Special Situations • Cost

AESO Recommendation Approval of Need* on Need

Transmission Facility Owner Approval of Routing consultation, detailed and Facilities line design and routing

*Need and facilities applications may be ﬁled together in some circumstances

Alberta’s Transmission Development Process

1. The Need: the AESO studies the need for transmission development, determines a preferred alternative and applies to the Alberta Utilities Commission for approval

2. The Facilities (lines, towers and substations): To meet the need, the Transmission Facility Owner applies to the Alberta Utilities Commission for approval to construct and operate facilities
